Sunny Po is a Cardiac Electro-physiologist and has his expertise in “The effects of the autonomic nervous system on cardiac arrhythmias”. He has discovered that simultaneous activation of the sympathetic and parasympathetic nervous system plays a great role in triggering atrial fibrillation. He also pioneered the therapy of using low-level vagal stimulation at the strength not slowing the sinus rate or atrioventricular conduction to treat atrial fibrillation.

Abstract:

Atrial fibrillation (AF) is the most commonly encountered arrhythmia. Catheter or surgical ablation, aiming at isolating the pulmonary veins to eliminate the triggers and substrate of AF is the therapy of choice for drug-refractory AF. Despite the advances of the ablation technologies, the success rate of AF ablation remains disappointing. It is evident that pulmonary vein isolation (PVI) is not enough to treat even the earliest stage of AF, paroxysmal AF, not to speak more advanced stages of AF. It is known that simultaneous activation of the sympathetic and parasympathetic nervous system plays a major role in the initiation and maintenance of AF. Interventions targeting these neural elements have been shown to favorably affect the clinical course of AF. Multiple preclinical studies demonstrated that low-level vagal stimulation at the strength not slowing the sinus or atrio-ventricular conduction was capable of suppressing AF initiation as well as terminating AF. Injection of botulinum toxin into major atrial ganglionated plexi, the integration centers of the cardiac autonomic nervous system, not only prevented post-operative AF in paroxysmal AF patients undergoing open-heart surgeries but also significantly suppressed the progression of AF in these patients. Recently, a novel therapy by transcutaneous stimulation of the auricular branch of the vagus nerve demonstrated its efficacy on shortening the AF duration, prolonging the atrial effective refractory period as well as suppressing the inflammatory markers such as TNF-α and CRP in paroxysmal AF patients undergoing AF ablation. Results of these recent clinical studies indicate that autonomic neural modulation may be a novel and noninvasive therapy for patients suffering from drug-refractory AF.

Abstract:

Porphyromonas gingivalis have been found in atherosclerotic lesions in humans. We developed a murine model of atherosclerosis using a 60% fat diet and gavage of PCB-77 and/or P. gingivalis. The model was assessed by histological examination of the aortic sinus, and ELISA assays for biomarkers of damage to the endothelial glycocalyx. C57/BL6 mice were raised from six weeks on either regular diet or a 60% fat diet. PCB-77 and/or P. gingivalis (ATCC 33277) suspensions were administered by oral gavage and mice sacrificed on days 10, 15 or 20. Frozen sections were cut through the arotic valve and analyzed for the presence and size of plaques, amount of fibrous tissue and inflammation. ELISA test kits measured thrombin-anti-thrombin complex, anti-thrombin III, total plasminogen activation inhibitor-1, syndecan 1, heparan sulfate and hyaluronan synthase 1. Animals receiving one PCB-77 gavage and one bacterial gavage demonstrated a low level of fibrous tissue and fat staining with a moderate level of inflammation. Fat staining was observed in foam cells in the artery walls of two sections in the aortic sinus with cholesterol inclusions. Most mice receiving three gavages of PCB-77 showed a moderate level of fat staining with low inflammation. Significantly higher levels of PAI-1 in mice were receiving one PCB-77 gavage and one bacterial gavage than in the control group. Levels of heparan sulfate detected in mice receiving three gavages of PCB-77 were significantly higher than in the control group. The levels of syndecan 1 and hyaluronan synthase 1 in the mice receiving three gavages of PCB-77 were significantly higher than in controls. The data show that administration of PCB and P. gingivalis to mice fed a high fat diet resulted in pathological features and biomarker abnormalities indicative of the presence of cardiovascular disease.

Lingfang Zeng has his expertise in Stem Cell Research in Vascular Biology field, specifically on Mechanotransduction, Epigenetic Modification and Alternative Splicing. He has done extensive investigation on HDAC3, HDAC7 and IRE1α/XBP1 signal pathway. His current research focuses on Alternative Translation. His group found that small open reading frame within so-called non-coding area or non-coding RNA could be translated to produce functional small peptides. In addition to ATG, they found that other codons could also initiate the translation to produce more small peptides.

Abstract:

Histone deacetylase 7 (HDAC7) belongs to the class II HDAC family and plays a pivotal role in the maintenance of endothelium integrity. There are eight splicing variants in mouse HDAC7 mRNAs. Within the 5’ terminal non-coding area of some variants, there exist some short open reading frames (sORFs). Whether these sORFs can be translated or resulting peptides play roles in cellular physiology remain unclear. In this study, we demonstrated that one sORF encoding a 7-amino-acid (7-aa) peptide could be translated in vascular progenitor cells (VPCs). Importantly, this 7-aa peptide (7A) could transfer the phosphate group from the phosphorylated Ser393 site of MEKK1 to the Thr145 site of 14-3-3γ protein. The phosphorylated 7A (7Ap) could then directly phosphorylate 14-3-3γ protein in a cell-free, in-gel buffer system. The adjacent histidine and proline residues are essential for the phosphate group reception and transfer. In vitro functional analyses revealed that 7A and 7Ap increased VPC self-renewal and migration and enhanced vascular endothelial growth factor (VEGF)-induced VPC migration and differentiation toward the endothelial cell (EC) lineage, in which MEKK1 and 14-3-3γ served as the upstream kinase and downstream effector, respectively. Knockdown of either MEKK1 or 14-3-3γ attenuated VEGF-induced VPC migration and differentiation. Exogenous 7Ap could rescue the effect of VEGF on the MEKK1 siRNA-transfected VPCs but not on the 14-3-3γ siRNA-transfected VPCs. In vivo studies revealed that 7A, especially 7Ap, induced capillary vessel formation in matrigel plug assays, increased re-endothelialization and suppressed neointima formation in the femoral artery injury model, and promoted foot blood perfusion recovery in the hind limb ischemia model by increasing Sca1+ cell niche formation. These results indicate that the sORFs within the non-coding area can be translated and that 7A may play an important role in cellular processes such as proliferation, migration and differentiation by acting as a phosphorylation carrier.

Abstract:

Fight against reducing the disability in heart failure patients is on and tremendous advancements in management of such patients with low ejection fraction over past few decades has improved the prognosis. Wealth of research data is available on this, wherein the scientists have delved deep into studying the apoptosis of myocytes and how the failing cells can be brought back into function by targeting the maladaptive neurohormonal pathways. Across the spectrum of the heart failure patients, the following range of pharmacotherapy prescribed over the past years has definitely lowered the hospital admission rates and prolonged survival but still the readmission rates are high and financial burden on the healthcare systems are alarming–diuretics, renin-angiotensin-aldosterone system inhibitors, B-blockers, digoxin and vasodilators being the mainstay of therapy. The discovery of two new classes of drugs has marked a new beginning in the care of chronic heart failure patients. Ivabradine and sacubitril/valsartan seem to be promising agents in improving the functional capacity and quality of life, reducing the hospital readmission rates and mortality. They reduce the stress on the myocardium by reducing the heart rate and improve the blood flow by relaxing the vessels thereby improving clinical outcomes. End stage heart failure patients still queue up for heart transplantation worldwide but lack of available donors necessitates them to use ventricular assist devices (like LVAD) as a bridge therapy in capable centers. ECMO also has been used for short term circulatory support. The key focus in this talk will be on novel drug treatment for systolic heart failure.

She is supported by the Bradley Merrill Patten Research Fellowship and by an American Heart Association Pre-doctoral Fellowship.

Abstract:

Myocardial infarction (MI) elicits inflammatory reactions that are orchestrated by a wide range of immune cells including macrophages. Reprogramming macrophages towards a resolving and reparative phenotype is a potential therapeutic approach for MI. However, how to modify macrophages in order to improve cardiac injury is not clear. Interleukin 4 receptor alpha (IL4Ra) activation is one of the major alternative activated macrophage (also names M2 macrophage) inducers, so IL4Ra is a potential macrophage modifier. Here, we knocked out IL4Ra from myeloid cells to determine how IL4Ra signaling is involved in cardiac remodeling post MI. Myeloid-specific IL4Ra knockout (MyIL4RaKO) did not show significant change in cardiac hypertrophy and interstitial fibrosis. There was decreased infarct size at one week post MI, but by three weeks there was no significant difference in infarct size. We saw significantly increased infarct thickness and perivascular fibrosis at three weeks, indicating the involvement of IL4Ra signaling in cardiac remodeling. Importantly, along with these significant changes in cardiac remodeling, MyIL4RaKO mice showed significantly decreased cardiac function at three weeks post MI. IL4Ra signaling was significantly inactivated in macrophages; however no change was shown in macrophage polarization in heart tissues post MI. In conclusion, IL4Ra signaling in myeloid cells is critical in maintaining proper cardiac remodeling and cardiac function post MI, which suggests the potential of modifying macrophages through enhancing IL4Ra signaling as a therapeutic strategy for MI.

Abstract:

Statement of the Problem: Cardiovascular disease (CVD) is the primary cause of death worldwide causing 29.6% in 2010. In the UK, CVD was the second cause of mortality, responsible for 27% deaths in 2014 and 48% of all deaths in Greece in 2012. CVD is a result of risk factors such as hypertension, dyslipidemia, overweight/obesity, stress, smoking, physical inactivity and diabetes. CVD prevention consists of two stages: Primary and secondary. Pharmacists, one of the most accessible healthcare professionals, do not have a clear role in the existing pathways. In our view, there are three prevention stages: Primary, secondary and tertiary. The primary prevention constitutes enhancing awareness and initial screening of the public for CVD risk factors (obesity, lack of exercise, alcohol misuse and tobacco use) in order to estimate their CVD risk. Pharmacists could offer services such as weight management, alcohol brief intervention, smoking cessation and health checks. Secondary prevention is the management of post-diagnosis risk conditions (diabetes, hypertension and dyslipidemia) in order to prevent the incidence of a CVD disease. At this stage, pharmacists could provide services with a view to optimize medicines to improve medication adherence and to offer lifestyle advice. Tertiary prevention is the linkage between prevention and treatment for those who already suffered a CVD episode with a view to decreasing the risk of a secondary episode or mortality.

Methodology & Theoretical Orientation: A qualitative study utilizing semi-structured interviews with UK and Greek pharmacists was undertaken to explore their current and future roles in CVD prevention. The conceptual framework used was based on the results of the literature search conducted on the pharmacist's role in CVD risk factors and conditions. The interview schedule, which included 28 questions in three sections, was designed based on the proposed CVD prevention pathway. Purposive sampling was used, obtaining 40 participants in total for both countries.

Results: The analysis identified the following themes; role recognition and priority services. Both UK and Greek pharmacists played a role in secondary prevention, after risk conditions have been diagnosed. They are eager to monitor patients’ blood pressure or blood glucose when necessary, and provide lifestyle advice when they dispense the prescribed medications to them. Furthermore, in Greece it was identified that pharmacists had an appetite to initiate CVD prevention services. Pharmacists were willing to start a weight management programme to help their clients to reduce their CVD risk. Therefore, a weight management service was designed and is currently being evaluated.

Conclusion & Significance: This study identified UK and Greek pharmacists’ perspectives on their role in CVD prevention. Pharmacists’ role is mainly focused in secondary and less in primary and tertiary CVD prevention. However, in Greece, pharmacists recognized a potential role in primary prevention and early screening of CVD. There is a need of more work targeted in tertiary prevention to reduce complications and the chance of a secondary or a third CVD episode as well as premature mortality.

Andrey V Kuznetsov has worked on the problems of delicate mechanisms of energy metabolism in the heart and their changes under pathophysiological conditions. He has studied mitochondrial function and regulation in normal cells and in various pathological states, in particular in the field of mitochondrial cardiac system, mitochondrial interactions with other intracellular structures and systems, performing analysis of mitochondria in situ and in vivo. Also, he studied the roles of mitochondrial damage in ischemia reperfusion injury, apoptosis, calcium homeostasis, oxidative stress, mitochondrial ROS production, cardiac and muscle diseases with imaging of mitochondria and mitochondrial function, mitochondrial dynamics (fission, fusion, motility) in various living cells. He has extensive knowledge in cardiac bioenergetics and mitochondrial physiology and experience in optical imaging (fluorescent, two-photon) of single cell and single mitochondria, imaging of mitochondrial Ca2+, ROS, membrane potential, mitochondrial dynamics for basic science and in clinically oriented studies.

Abstract:

The control of mitochondrial function is a cardinal issue in the field of cardiac bioenergetics, and the analysis of mitochondrial regulations is central to basic research and in the diagnosis of many diseases. Interaction between cytoskeletal proteins and mitochondria can actively participate in mitochondrial regulation. Potential candidates for the key roles in this regulation are the cytoskeletal proteins plectin and tubulin. Analysis of cardiac cells has revealed regular arrangement of β-tubulin II, fully co-localized with mitochondria. β-tubulin IV demonstrated a characteristic staining of branched network, β-tubulin III was matched with Z-lines and β-tubulin I was diffusely spotted and fragmentary polymerized. In contrast, HL-1 cells were characterized by the complete absence of β-tubulin II. Comparative analysis of cardiomyocytes and HL-1 cells with cardiac phenotype revealed a dramatic difference in the mechanisms of mitochondrial regulation. In the heart, colocalization of β-tubulin isotype II with mitochondria suggests that it can participate in the coupling of ATP-ADP translocase (ANT), mitochondrial creatine kinase and VDAC. This mitochondrial supercomplex is responsible for the efficient intracellular energy transfer via the phosphocreatine pathway. We found also that in skeletal muscle of plectin knockout mice, mitochondrial content was reduced; mitochondria were aggregated in sarcoplasmic and subsarcolemmal regions, and were no longer associated with Z-disks. Our results show that the depletion of distinct plectin isoforms (P1b and P1d) affects mitochondrial network organization and function in different ways. Existing data suggest that cytoskeletal proteins may control the VDAC, contributing to the regulation of mitochondrial and cellular physiology.

Abstract:

The transurethral prostatectomy syndrome (TURS) is defined as severe vascular hypotension reaction that complicates endoscopic surgery as a result of massive irrigating fluid absorption causing severe acute dilution hyponatremia (HN) of <120 mmol/l. The vascular shock is usually mistaken for one of the recognized shocks and volumetric overload shock type 1 (VOS1) is overlooked making volumetric overload shock type 2 (VOS2) unrecognizable. In adults VOS1 is induced by the infusion of 3.5-5 liters of sodium-free fluids and is known as TURS or HN shock. VOS2 is induced by 12-14 liters of sodium-based fluids and is known as the adult respiratory distress syndrome. The most effective treatment for VOS1 and VOS2 is hypertonic sodium of 5%NaCl or 8.4% sodium bicarbonate. The literature on TURS is reviewed and the underlying pathoetiology is discussed. As Starling’s law for the capillary-interstitial fluid transfer, which underlies the principles of fluid therapy, proved wrong an alternative mechanism was found by studying the hydrodynamics of the porous orifice (G) tube akin to capillary. Incorporating the G tube in a chamber (C), representing the interstitial space surrounding a capillary, demonstrated a rapid dynamic magnetic field-like fluid circulation between the C and G tube lumen. The G-C phenomenon is autonomous having both filtration and absorption forces making a true replacement for Starling’s law in every tissue and organ of the body.

Abstract:

Objectives: Myocardial ischemic reperfusion injury remains the most uncontrolled aspect of cardiac operations. This study aims at testing the hypothesis that aminophylline could serve as a potential myocardial protector against reperfusion injury during coronary artery bypass grafting (CABG).

Methods: A prospective, randomized, single blinded, placebo - controlled study involving 60 patients divided into two groups. Group A (30 patients) preoperatively received aminophylline, 200 mg orally per day for 3 days with a total dose of 600 mg. Group B (30 patients) was given placebo. All patients underwent uniform pre/intra/post-operative management. Assessment of cardiac markers (Troponin I) and cardiac enzymes were done before induction of anesthesia, after 30 min of aortic cross clamping and postoperatively (1, 24 and 48 hours). Preoperative concentration of aminophylline in serum was measured. Postoperative, 12 lead ECG after 48 hours and echocardiographic full study examination at the 6th day were examined.

Results: Total ICU stay hours and ventilation hours were statistically higher (p-value<0.05) in group B (67.20±21.28 and 16.47±8.76 hours, respectively) than in group A (46.87±14.46 and 12.20±3.56 hours, respectively). The need of inotropes in group A was lower than that in group B in the immediate postoperative period. However, Troponin I and cardiac enzymes in both groups were of no statistical significant difference (p-value>0.05).

Conclusions: Aminophylline may have beneficial role in CABG surgeries by decreasing the ventilation hours, need of inotropic support and total ICU stay hours. However, there was no relevant impact on cardiac marker and enzymes.

Abstract:

Purpose: The significance of electrocardiographic ECG changes during adenosine stress test is debatable. This study will further elaborate the significance of these changes in predicting the possibility of CAD.

Methods: This was a retrospective observational registry performed in a single center at the Kingdom of Saudi Arabia. The data were collected from the nuclear medicine database identifying all the reported Gated myocardial perfusion SPECT with adenosine stress tests between January 2013 and January 2014. The adenosine dose were fixed with all patients based on body weight and was given as a continuous infusion of 140 mcg/kg/min over a 6-minute period.

Results: There were 346 patients identified with cardiac nuclear scans in the pre-specified time frame who were subjected to adenosine stress scan. 152 of these patients were male accounting for 44% of the total population. Average age at the time of examination was 60.82±11.29 years. Patients were presented with one or more risk factors. Patients with base line abnormalities, past history of CAD with or without PCI or CABG and previous MI were excluded from the study. Ninety-eight patients (28%) were reported as positive for CAD, 40 patients were reported with ischemic ECG changes (12%) during adenosine infusion, 23 patients who have ischemic changes were positive on MPI, while 17 patients who have positive ECG had a negative MPI. Odd Ratio (OR) was 4.16, 95% C.I. was (2.11-8.18). Fisher Exact test was applied and showed a P value of <0.01. No reported case of asystole, myocardial infarction or complete heart block in this study period.

Conclusions: Our study showed that the probability of a positive MPI is 4 times higher with positive ECG ischemic changes during adenosine stress test and consequently these ECG ischemic changes should be taken in consideration in the final report.

Abstract:

Cardiac Resynchronization Therapy (CRT) is known as a highly effective therapy in advanced heart failure patients with cardiac dissinchrony. However, still one third of patients do not fully respond to CRT. Among the many contributors for the high rate of non-responders, the lack of procedures dedicated to CRT device settings optimization is known as one of the most frequent. On the other side, the echocardiography optimization is not widely used in the real world of CRT follow up visits. Thus, device-based techniques have been developed to by-pass the need of repeated echo evaluations to optimize CRT settings. There are multiple drivers of non-response. Common factors are AV/VV timing, reduced BiV pacing, LV lead placement, presence of arrhythmias, appropriate patient selection, patient compliance and presence of comorbidities. The current challenge facing practitioners is to maximize the rate of patients who respond to CRT and the magnitude of the response. A very particular and important subgroup of HF population with CRT includes the patients with AF since the optimal use of CRT in this cluster remains uncertain. The current area of interest achieving these goals includes the tailoring patients’ selection, the individualizing LV placement and, in particular, the application of new technologies and algorithms for CRT delivery in optimal fashion, reducing inappropriate shocks incidence and optimizing device longevity.

Qiuping Zhang has her expertise in “Nesprin family research in Cardiovascular Biology field, specifically on understanding the complex roles of nesprin-1 and -2, family members of multi-isomeric scaffolding proteins, in regulating normal and pathological processes in the heart and muscle”. She has studied extensively the role of nesprins in myoblast differentiation and function as well as mutations in nesprin-1 or -2 in associations with Emery Dreifuss muscular dystrophy and dilated cardiomyopathy. Her current research focuses on “Defining the roles of nesprins in cardiac cell function by determining the functional significance of novel nesprin-1 and -2 mutations on the linker of nucleoskeleton-and-cytoskeleton complex that connects the nuclear envelope to the actin cytoskeleton, and also identifying novel roles for nesprins in the sarcomere”. This may reveal novel pathways that contribute to the development of cardiac cell dysfunction and cardiomyopathy.

Abstract:

Nesprins-1 and -2 are highly expressed in skeletal and cardiac muscle and together with SUN (Sad1p/UNC84)-domain containing proteins and lamin A/C form the linker of nucleoskeleton and cytoskeleton (LINC) bridging complex at the nuclear envelope (NE). Mutations in nesprin-1 and -2 have previously been found in patients with autosomal dominant Emery-Dreifuss muscular dystrophy 4 (AD-EDMD 4, OMIM 612998) and 5 (AD-EDMD5, OMIM 612999) as well as dilated cardiomyopathy (DCM). In this study, three novel rare variants (R8272Q, S8381C and N8406K) in the C-terminus of the SYNE-1 gene (nesprin-1) were identified in 7 DCM patients by mutation screening. Expression of these mutants caused nuclear morphology defects and reduced lamin A/C and SUN2 staining at the NE. GST-pull down indicated that nesprin-1/lamin/SUN interactions were disrupted. Nesprin-1 mutations were also associated with augmented activation of the ERK pathway in vitro and in hearts in vivo. During C2C12 muscle cell differentiation, nesprin-1 levels are increased concomitantly with kinesin light chain (KLC-1/2), and immunoprecipitation and GST-pull down showed that these proteins interacted via a recently identified LEWD domain in the C-terminus of nesprin-1. Expression of nesprin-1 mutants in C2C12 cells caused defects in myoblast differentiation and fusion associated with dysregulation of myogenic transcription factors and disruption of the nesprin-1 and KLC-1/2 interaction at the outer nuclear membrane. These findings support a role for nesprin-1 in myogenesis and muscle disease, and uncover a novel mechanism whereby disruption of the LINC complex may contribute to the pathogenesis of DCM.

Abstract:

Introduction & Objective: Sildenafil (phosphodiesterase inhibitor type 5) has been successfully used to treat primary pulmonary hypertension. Mitral valve disease notably stenotic lesion is a long standing disease, in developing countries late detection results in increase association with severe secondary (PAH) pulmonary hypertension. Right ventricular (RV) failure is a leading cause of increased morbidity and mortality of patients with severe pulmonary hypertension undergoing mitral valve surgery. The study aims to confirm the effectiveness of preoperative oral sildenafil in decreasing the incidence of RV failure in this category of patients.

Methods: Eighty patients scheduled for mitral valve replacement surgery with severe PAH, RV systolic pressure (RVSP) ≥60mmHg were included in the study. Patients were randomized into two groups: Gr C - placebo (N=40), and Gr S - Sildenafil (N=40) with oral sildenafil 25 mg eight hourly for 48 h before surgery with the last dose given 25 mg in 10 ml via nasogastric tube after induction of anesthesia. In both group the need for inotropes was recorded and doses were titrated to achieve hemodynamic stability during and after cardiopulmonary bypass (CPB).

Results: Pulmonary artery pressure was significantly reduced in the sildenafil group. Ventilation time was less in the sildenafil group but without statically significant value, CPB time was significantly lower in the sildenafil group (p=0.05) and postoperative ITU stay was significantly lower (P<0.001) in sildenafil group. The requirements of inotropes notably dobutrex and milrinone were significantly more with placebo group compared to sildenafil group.

Conclusions: It is concluded that sildenafil is safe and effective in reducing severe pulmonary hypertension when given to patients prior to the mitral valve replacement surgery; which facilitated weaning from CPB.

Abstract:

Aortic dissection has varying presentations. This disease entity can mimic other acute emergencies posing a diagnostic dilemma. There should be high index of suspicion in diagnosing aortic dissection in patients of all ages. With newer advanced modalities of diagnosis and the risk score algorithms, the clinical outcome of an otherwise catastrophic disease has improved to a great extent. All the patients of collagen disease, bicuspid aortic valve, coarctation of aorta, uncontrolled HT and unexplained AR should be thoroughly evaluated. This interesting case of a 73 year old elderly gentleman presented with sudden onset chest discomfort radiating to the jaw with a short episode of sudden shortness of breath. The physical examination was unremarkable with stable hemodynamics and well felt peripheral pulses with no discrepancy. His D dimers were found to be markedly elevated with raised serum creatinine. The cardiac enzymes were normal. ECG was not indicative of myocardial ischemia. Echo showed minimal AR, mild anterolateral pericardial effusion with good LV systolic function and PA pressure of 32 mm Hg. He was hyper-tensed on medication with history of CVA 3 years ago and was on Warfarin since then. He remained stable hemodynamically for the initial 24 hours after admission, later he developed atrial fibrillation with controlled ventricular response. Owing to renal dysfunction, instead of pulmonary CT angiography, VQ scan was done to rule out pulmonary embolism. It revealed multiple perfusion defects in both lung fields. Simultaneous repeat echocardiography revealed increase in grade of AR to more than 1/4 and mild increase in PE with echogenicity seen within the effusion behind RV (possibly blood). CT chest was immediately performed which clinched the diagnosis of type A aortic dissection. He was immediately referred to the cardiac surgeon who did emergency surgical correction with successful recovery.

Abstract:

Cocaine abuse can cause acute and chronic cardiovascular complications which include, coronary artery spasm , aortic dissection,  myocardial infraction, left ventricular dysfunction and  thrombosis that  can  lead to fatal thromboembolic event.  It has been well described in the literature that  cocaine  significanlty  increases the risk of  ischemic stroke  in young adults within 24 hours of use. Interestingly  the risk of cerebral infarct  relating  to acute cocaine comsuption  is notably  higher  than the usuall well known  stroke  risk factors.

A 32 years old gentleman  who is known to have history of  cocaine abuse, presented  with an acute stroke, myocardial infraction and significant large left ventricular thrombus which took place within  short time window following cocaine abuse.

Abstract:

Background

Hypertension is one  of the cardiovascular variables raised state, systolic and diastolic blood pressure are its parameters that can be easily measured, alteration of blood pressure is commonly observed in different condition, but persistent elevated state is one of the alarming remark of the cardiovascular  biology, therefore status of blood pressure in the adult in different anthropometric measures are adopted but especial focus is given to waist circumference at different anatomical site said to be one of the indicator of adiposity depots that is associated with cardio metabolic risk.

Aims: Hence,  this study  aims to find whether  addition of waist circumference (WC) to body mass index (BMI;  kg/m2)  play additive or strong independent  role in predicting   health risk than does BMI alone.

Methods: A community based cross sectional study  was conducted by incorporating  total of substantial number   (more than 100) of  subjects in the data who were male only  older than 25 years, non smokers, non alcoholic, didn’t have history of taking  any type of medication, non vegetarian with normal physical activity and were residents in the urban and rural areas throughout, were included in the present study. Waist circumference referenced to umbilicus measured by non tensile and non flexible measuring tape and at the mean time height and weight were also recorded by standard device in order to calculate BMI and blood pressure was measured  by Aneroid sphygmomanometer of the respective  subject subsequently data analysis was made by using SPSS  to compare the BMI and Waist circumference relationship with blood Pressure independently  to identify their  relationship with hypertension.

Results: Keeping few exceptional aside, Both BMI and Waist Circumference exhibited positive association with blood pressure, while the waist circumference was more strongly associated with hiking of blood pressure and also BMI is not always the relating parametric tool to metabolic disease as was conventionally considered.

Conclusion

The result and analytical data showed that (P<0.05) there is significant strong correlation of blood pressure with waist circumference comparatively more than BMI thus WC alone can significantly predict the co-morbidity therefore this study  approach to suggest and hints to follow as a routine task  for measuring Waist circumference while taking inference for diagnosing hypertension risk at least in male.

He started the Department of Cardiothoracic Surgery in this Medical College Hospital which is located in a village called kalitheerthalkuppam, Pondicherry, India. We have started this cardiothoracic program and open heart surgeries since April 2016 onwards till date. His team has successfully completed more than 90 open heart surgeries in a span of 10 months which includes beating heart CABG, On-Pump CABG, valvular heart surgeries and both adult and pediatric congenital heart surgeries.

Abstract:

To discuss the feasibility of starting and establishing a superspecialty department like cardiothoracic surgery in rural and semi-urban centers is a herculean task. We planned to setup a pilot project on how to start a superspecialty department in Rural and semiurban places and also to do open heart surgical procedures at an affordable cost. We discussed our plan with a medical college hospital in our locality and they helped us to start this within their premises with available infrastructure. We closely followed up the inpatient crowd of the hospital and secured cases from all fields of medicine and especially from cardiology department. We managed to maintain a registry of cases and categorized patients based on their symptoms and who needed surgery. Our next task of building the infrastructure was aimed and we procured materials necessary to start this program which included setting up of operation theatre, CT ICU and postoperative wards. Our other task of recruiting staffs for caring the patients was breathtaking and was managed successfully. After establishing this we started our first open heart procedure on April 2016 and continued from thereon. Today, we had crossed more than 90 open heart surgeries apart from vascular and thoracic surgeries. We have now established a center which can perform all cardiac surgery programs that are done at any standard hospitals or medical colleges in major cities. Today we proudly say that the task is well started and could be achieved with the help of a supporting team of dedicated doctors and paramedical staffs and equally supported with the necessary infrastructure by the hospital to cater the underprivileged people with the support of various schemes and insurance assistance.

Abstract:

Statement of the Problem: Mitral valve can be accessed through left atrium or via inter-atrial septum. Although left atrium is the traditional approach, trans-septal approach gives better exposure in difficult cases. This retrospective study was designed to evaluate the safety, pitfalls and effectiveness of the extended vertical trans-septal approach for routine mitral valve exposure.

Methodology & Theoretical Orientation: It is a retrospective study of 1017 consecutive patients undergoing an isolated primary mitral valve procedure (repair, replacement) through a median sternotomy between the years 2000 and 2015 by eight different surgeons. Out of these 135 patients were operated by extended vertical trans-septal approach (EVTSA, group A) while 882 patients were accessed through traditional left atrial (LA, group B) approach via posterior inter-atrial groove.

Findings: There were 135 patients (M/F=56/79) in group A and 882 patients (M/F=398/484) in group B. Logistic euro score was significantly lower in EVTSA group (0.61 vs. 0.90 p=0.000001). In LA group, there were more patients with pre-operative TIA or stroke (94 vs. 6 p=0.005), and this difference was statistically significant. Cumulative cross clamp time was 82 (44-212) minutes (EVTSA) and 78 (30-360) minutes (LA) groups (p=0.271) while cardiopulmonary bypass time was 107 (58-290) and 114 (43-602) minutes (p=0.121). Post-operative blood loss was 415 ml (EVTSA) versus 427 (LA) ml (p=0.273). No significant difference was found in the incidence of post-operative atrial fibrillation (p=0.22) or heart block requiring permanent pacemaker (p=0.14).

Conclusion & Significance: Extended vertical trans-septal approach is safe and reproducible. It gives excellent exposure of the mitral valve. It is reasonable way to routinely expose mitral valve without significant increase in cross clamp time, post-operative arrhythmia, heart block or bleeding.

Abstract:

Statement of the Problem: The purpose of this study was to assess the effectiveness of cognitive behavioral couple therapy (CBCT) in treating heart disease by managing marital conflict among female patients with coronary heart disease.

Methodology: This study was completed using repeated measure design with a sample of 20 female cardiac patients approached at Institute of Cardiology Multan who were matched on the characteristics of age, education and economic class. This sample was then randomly assigned to the intervention (n=10) and control groups (n=10). CBCT was administered to the intervention group (n-10) while control group was on medication only. Data were collected on measures of Kansas Marital Satisfaction (KMS) Scale, Revised Dyadic Adjustment Scale (RDAS) and coronary heart disease symptoms check list (CHDS) from both groups before and after the administration of CBCT to intervention group. The data were analyzed by employing Kolmogorov-Smirnov test, Mann-Whitney U test and Wilcoxon W test.

Findings: Significant differences were found in pre and post scores on marital satisfaction scale, dyadic adjustment scale and symptoms of CHD for intervention group. The CBCT was found to be effective in increasing stability and satisfaction in the marital relationship of females. Female Patients after CBCT also reported a decrease in their symptoms of CHD.

Conclusion: From the present findings, CBCT seems very effective in resolving conflicts and decreasing severity of symptoms of CHD among female cardiac patients.

Recommendations: CBCT can be considered as practicable method in managing marital conflicts associated with CHD.

Abstract:

Congenital cardiac disease is not uncommon in daily medical practice. Many studies have been carried out worldwide, showing incidence variation in different parts of the world as 5-10/1000 live birth. In Bangladesh, a mere study was done in this respect. This retrospective study was conducted from the records preserved in hospital register, compiled by the author from pediatric cardiology and cardiac surgery department over a period of 4 years extends from 2010-2013 in National Institute of Cardio Vascular Diseases Hospital. 6520 cases of live births weighing more than 1500gm and age over 28th weeks of gestational period were recorded by clinical examination and echocardiography with color Doppler. This study showed that 196 babies out of 6520 live births had CHD as 30/1000 live births. Study also expressed that higher incidence of CHD was observed in preterm baby than full term baby. Among the congenital heart lesions, atrial septal defect, ventricular septal defect, Patent ductus arteriosus, Tetralogy of Fallot`s, TGA were commonest having 20.41%, 13.78%, 10.71%, 8.67% and 4.59%, respectively. 15.81% of the patients had other associated somatic anomalies among which down syndrome was the commonest (7.14%). CHD of various patterns deserves crucial challenge among the newborns for management in Bangladesh. Various factors like high maternal age, drugs intake, antenatal infection, family history, gestational DM, down’s syndrome, mother having SLE are related to these diseases. Moreover, appropriate research can be accomplished taking large relevant sample gathering from different tertiary medical college hospitals to reveal actual scenario to prevent and treat the diseases.

Abstract:

In most countries worldwide, the number of patients with chronic heart failure (HF) is growing with 1-3% of the adult population suffering from this syndrome, rising to about 10% in the very elderly. In the near future, a large part of the worldwide population will suffer from heart failure and society will be faced with the consequences. On average, one in five patients is readmitted within 12 months, making heart failure one of the most common causes of hospitalization in people over 65 years of age. A multidisciplinary team approach involving several professionals with their own expertise is important in attaining an optimal effect. Physicians, nurses and other health care professionals are keys ensuring the delivery of evidence based care. Markers of clinical (in) stability, psychosocial risk factors, and issues related to patient mobility might be important indicators to determine which inter-professional service might be most effective for which patient. Current HF guidelines recommend that HF patients are enrolled in a multidisciplinary-care management program to reduce the risk of HF hospitalization. A multidisciplinary approach to HF may reduce costs, decrease length of stay, curtail readmissions, improve compliance and reduce mortality. An important limitation, however, is the substantial heterogeneity in both the terms of the models of care and the interventions offered, including: clinic or community-based systems of care, remote management and enhanced patient self-care. Conventional trials that randomize individual patients may not be the best way to test the effect of a service; novel approaches, such as the cluster randomized controlled trial, may be superior. It is unlikely that any one approach is optimal. The best form of care might seek to compensate for the weaknesses of each approach by exploiting their strengths. A strong HF cardiology lead, supported by primary care physicians, nurse specialists and pharmacists in the hospital and community with the ability to offer patients remote support might offer the best service. Key to the success of multidisciplinary HF programs may be the coordination of care along the spectrum of severity of HF and throughout the chain-of-care delivered by the various services within the healthcare system. Further research is warranted to identify the most efficacious multidisciplinary approaches to HF.

Learning Objectives: Objectives are to: Define multidisciplinary approach to HF; examine the literature role and recommendations of multidisciplinary in HF and; identify barriers to optimal models of multidisciplinary approach to HF.

Abstract:

Introduction: Out-of-hospital cardiac arrest in the absence of structural heart disease is rare and can be due to subclinical cardiomyopathy or primary electrical disorders. Adverse collagen remodeling may occur in cardiac arrest patients; MMP-9 is proven to help risk stratification.

Clinical Case Description: In 2005, R.R, a 35 year old metal-worker, surprisingly began to show high values of MMP9. TIMPs, MMP2, NT-pro-BNP and all the other laboratory tests, abdominal echography, electrocardiogram and echocardiography were within the reference range. 10 years later, R.R suddenly collapsed at home; his wife promptly began a successful cardiac massage, supported by territorial tele-emergency network. R.R was admitted to the intensive unit with frequent ventricular extrasystoles, left ventricular dysfunction. Medical history of his family includes sudden death of two paternal uncles; mother with Takotsubo syndrome. Unremarkable clinical examination and electrocardiogram showed no biochemical evidence of acute myocardial infarction; CRP elevation. Un-obstructed coronary arteries on coronary were revealed in angiography. Chest X-ray showed mild interstitial fibrosis. There were no signs of arrhythmogenic cardiomyopathy on Cardio-NMR.

Discharge Diagnosis: Discharge diagnosis was: “Resuscitated cardiac arrest, in subject without evidence of structural heart disease, treated with ICD bicameral system”.

Reviewing Clinical Information & Diagnosis: Familial histories of sudden death, mild endocardial irregularities, left ventricle enlargement, reduced ejection fraction, low EKG voltage are suggestive of familial cardiomyopathy. Welding, chest X-ray fibrosis, RCP is suggestive of welder’s lung. Then, reformulated diagnosis: Resuscitated cardiac arrest in sub-clinical familial cardiomyopathy, chronically subjected to professional cardio-toxic damage.

Conclusions & Implications for Clinical Practice: R.R lethal arrhythmia was firstly considered as “idiopathic” in nature, since process laboratory and radiology testing were not analyzed properly. Interestingly, long before cardiac arrest, MMP9 had begun to rise, announcing a cardio-pulmonary adverse remodeling. The case of R.R teaches us that early biomarkers such as MMP9, correct and timely diagnosis, tele-medicine and emergency services network could really save lives of patients at high risk of sudden death.

Abstract:

Heart failure (HF) is an increasingly common syndrome associated with high mortality and economic burden. A range of terms has been used to describe HF viz. chronic HF (CHF), acute HF (AHF), HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). Pathophysiology of HFrEF is complex. Landmark trails in patient with HFrEF include SOLVD-T, CIBIS-II, CHARM-Alternative and CHARM-Added, SHIFT, EMPHASISHF and PARADIGM-HF. Natriuretic peptides (NPs) are a group of hormones that have potent effects on sodium and fluid balance. Neprilysin is a zinc-dependent metallopeptidase that catalyses the degradation of various peptides. Inhibition of neprilysin increases bioavailability of NPs, bradykinin, and substance P, resulting in natriuretic, vasodilatory and anti-proliferative effects. LCZ696 is useful not only for the treatment of HF but also likely to be a useful antihypertensive drug. LCZ696 is a novel drug that comprises sacubitril (AHU377) and valsartan in a 1:1 molar ratio. It simultaneously inhibits neprilysin and blocks AT1 receptors. PARADIGM-HF is the first study to test the efficacy of LCZ696 on morbidity and mortality in patients with HFrEF. The trail was stopped early, according to pre-specified rules, after a median follow-up of 27 months, because the boundary for an overwhelming benefit with LCZ696 had been crossed. LCZ696 was associated with a significantly lower death from cardiovascular causes or first hospitalization (taken together-20% or separately 20-21%). Secondary endpoint viz. death from any cause, showed a 16% reduction (p<0.001). The superiority of LCZ696 over enalapril was not accompanied by important safety concerns. The LCZ696 group had a higher proportion of patients with non-serious angioedema, but not associated with an increase in serious angioedema.

Abstract:

Aim:C делана попытка нового анализа м еханизм а An attempt to study the mechanism of heart failure.

Method: Information search in the literature, participate in conferences, discussions with Russian leading cardiologists.

Result: Having heart failure means that for some reason your heart is not pumping blood around the body as well as it used to. Heart failure can be a major manifestation of virtually all diseases of the heart, including coronary atherosclerosis, myocardial infarction, acquired valvular disease, congenital heart disease, arrhythmias and cardiomyopathy. Population‐based echocardiographic studies have demonstrated that more than 50% of participants with left ventricular systolic dysfunction (generally defined as LVEF <35–40%) have no symptoms or signs of heart failure. How to interpret this data? How the heart can pump insufficient blood to one person and sufficient amount of blood to another? Where is the logic? The reason according to my theory of CVD is that, near liver, arteriovenous anastomoses (AVA) or cascade AVA opens for longer time than optimal. Veins overflow begin mechano-induced arrhythmia. Opened AVA lead to stagnation of blood in the area of small pelvis and ankle/feet. The other reasons are stasis of microcirculations, weight gain, varicose veins, endometriosis, prostatitis, hemorrhoids, thrombosis, and cancer. The development of these diseases is accompanied in most cases with heart failure.

Conclusions: It is necessary to correct the glaring errors in cardiology which are existing from past 50-100 years. It is necessary to develop pulse wave suppressors and artificial anastomosis with an adjustable diameter hole.

Josephine Achan is a young Researcher with special interest in Cardiovascular Disease. She is currently practicing at Uganda Heart Institute as a Physician and a second year adult Cardiology Fellow. She is involved in the local research in her country and currently part of Acute Myocardial Infarction in Uganda.

Abstract:

Introduction: Myocardial infarction is one of the leading causes of mortality worldwide with decreasing incidence in developed countries and increasing incidences in developing countries, Uganda inclusive. This increasing trend has been attributed to urbanization and changing life styles in developing countries. There is high burden of risk factors like hypertension and diabetes mellitus in our setting.

Aim: The purpose of this study is to describe the clinical presentation and in-hospital outcome among patients admitted with myocardial infarction at Mulago Hospital.

Method: This was a prospective cohort study that was conducted in Mulago Hospital complex and Uganda Heart Institute in 2013. 54 subjects were recruited during the eight months study period. Data collected through standardized questionnaire and blood samples obtained. Participants were followed for minimum of two weeks and maximum of one month.

Results: A total of 54 patients were recruited, 29/54 (63%) had ST segment elevation myocardial infarction (STEMI) and 17/54 (37%) had non-ST segment elevation myocardial infarction. Chest pain (66.7%) was the common presentation. Most patients in this study came to the hospital more than 72 hours with median time of presentation to the hospital from onset of symptoms 93.5 hours (SD 57.09, OR=1.002 95% CI 0.9-1.0). The mean age for the study participants was 58.7 (SD=+/-10) with more males 38/54 (70.4%) than females 16/54 (29.6%). Common associated symptoms were breathlessness 39/54 (54.7%), palpitations 21/54 (38.9%). Symptoms occurred at rest with exercise and emotional stress. Only 7/59 (13%) of the participants had low systolic and 11/54 (20.4%) low diastolic blood pressure. 18/54 (33.3%) had high systolic and 20/54 (37%) diastolic pressure at admission. 19/54 (35.2%) of participants had significant pulmonary rales at admission. 34/54 (63%) had New York Heart Association class I and 40/54(74.1%) were in Killip class I. Risk factors included past medical history of hypertension 35/54 (OR=1.53, 95% CI=0.48-4.90), diabetes mellitus (OR=1.52, 95% CI=0.46-4.95), dyslipidemia 7/54 (OR=1.73, 95.5 CI=0.29-10.10), high LDL cholesterol were higher risk for myocardial infarction. Low HDL (OR=1.9, 95% CI=0.55-6.58) confers higher risk for myocardial infarction compared to normal and high HDL cholesterol levels. Also similar patterns were seen in family history as positive for hypertension (59.3%) (OR=1.1, 95.5 CI=0.35-3.88) and diabetes mellitus (37%). Overall 10/54 (24.1%) developed shock, 10/54 (18.5%) had pulmonary oedema and congestive heart failure, 6/54 (11.1%) developed arrhythmia, 6/54 (11.1%) died in the hospital, and 2/54 (3.7%) had ventricular wall aneurysm formation. 1/54(1.9%) had stroke, reinfarction and thrombus formation.

Conclusion: Majority of patients admitted with myocardial infarction had STEMI and presented with chest pain. Most patients were males. Hypertension, diabetes mellitus and dyslipidemia were high risk factors. Almost half of the patients with STEMI developed pulmonary edema, shock, congestive heart failure and arrhythmia.

Abstract:

Statement of the Problem: Obesity which is excess fatty weight is one of the most predominant cardiovascular risk factor. The association between obesity and cardiovascular disease is complex and not limited to the standard risk factors like hypertension, dyslipidemia, and type 2 diabetes mellitus. Recent years researches have shown that obesity causes most cardiovascular diseases through mechanisms like subclinical inflammation, endothelial dysfunction, increased sympathetic tone, atherogenic lipid profiles, enhanced thrombogenic factors, and also through obstructive sleep apnea. The purpose of this study is to create awareness of obesity, its bad outcome and to awaken us on the lifestyle we live.

Methodological & Theoretical Orientation: Based on my research done in Ghana, people with issues of obesity have cardiovascular disease.

Findings: Several studies have shown association between obesity and prognosis among those with coronary disease and heart failure, this may be due to limitations of ways we define obesity. There are numerous data suggesting that measuring central obesity or total body fat content might be more appropriate than using the body mass index method alone.

Conclusion: The management of obesity is challenging and studies using lifestyle modification alone or with pharmacologic agents generally have limited success and high levels of weight regain. Bariatric surgery has proven to be an effective and safe way to induce and maintain significant weight loss but its limited to those with medically complicated obesity or people who are severely obese therefore urging imminent doctors and medical practitioners to thoroughly educate their patients who are obese or yet to get obese on the bad effect of obesity and also encourage them to exercise regularly which may reduce their weight and also help boost their metabolic activities hence keeping them healthy.

Abstract:

Background & Aim: Cardiac resynchronization therapy (CRT) reduces symptoms and improves left ventricular function in patients with heart failure due to left ventricular systolic dysfunction and cardiac dyssynchrony. We analyzed the clinical and echocardiographic outcome of CRT in heart failure patients.

Methods: A total 35 heart failure patients were included in this prospective observational study, conducted from Feb 2015–Feb 2016 in the cardiology department of NICVD, Dhaka. Demographic profile, clinical data and investigations including coronary angiogram were done. Patients underwent CRT-P (BiV pacemaker) or CRT-D (defibrillator) and were followed up. Clinical, electrocardiographic and echocardiographic study were performed before and three months after CRT implantation.

Results: After three months of BiV pacing, New York Heart Association functional class improved from 3.3±0.44 to 1.7±0.6 (p<0.001). Left ventricular end diastolic diameter was reduced from 67.9±5.2 to 61.9±5.9 mm (p<0.001) and left ventricular end systolic diameter was reduced from 56.4±6.5 to 50.5±7.2 mm (p<0.001). Ejection fraction was significantly increased after three months from 27.5±4.3% to 38.8±6.7%, (p<0.001).The average grade of mitral regurgitation was decreased from 1.49±0.65 to 0.43±0.61 (p<0.001). The number of hospitalization was also significantly reduced from 2.51±1.44 to 0.11±0.32 (p<0.001). Among the study patients, 71.4% patient was responders, 17.1% super responders and 11.4% non-responders.

Conclusions: Although the study was performed on a small number of patients, it can be considered that CRT had favorable hemodynamic and clinical results and reduced the need for hospitalization in our heart failure patients.

Abstract:

Statement of the Problem: Clinical trials have demonstrated that cardiac resynchronization therapy (CRT) is effective in patients with non-ischemic cardiomyopathy. However, patients with dilated-phase hypertrophic cardiomyopathy (DHCM) have been generally excluded from such trials. We aimed to compare the clinical outcome of CRT in patients with DHCM, idiopathic dilated cardiomyopathy (IDCM) or ischemic cardiomyopathy (ICM).

Methodology & Theoretical Orientation: A total of 312 consecutive patients (DHCM=16; IDCM=231; ICM=65) undergoing CRT in Fuwai hospital were studied respectively. Response to CRT was defined as reduction in left ventricular end-systolic volume (LVESV) ≥15% at six-month follow-up.

Findings: Compared with DHCM, IDCM was associated with a lower total mortality [hazards ratio, HR: 0.35 (95% confidence interval, CI 0.13-0.90)], cardiac mortality [HR: 0.29 (95% CI 0.11-0.77)] and total mortality or heart failure (HF) hospitalizations [HR: 0.34 (95% CI 0.17-0.69)], independent of known confounders. Compared with DHCM, the total mortality, cardiac mortality and total mortality or HF hospitalizations favored ICM but were not statistically significant. [HR: 0.59 (95% CI 0.22-1.61); HR: 0.59 (95% CI 0.21-1.63); HR: 0.54 (95% CI 0.26–1.15) respectively]. Response rate to CRT was lower in the DHCM group than the other two groups although the differences didn't reach statistical significance.

Conclusion & Significance: Compared with IDCM, DHCM was associated with a worse outcome after CRT; the clinical outcome of DHCM patients receiving CRT was similar to or even worse than that of ICM patients. These indicate that DHCM behaves very differently after CRT.
