Use Of Triple-Site Ventricular Pacing In A Patient With Severe Congestive Heart Failure And Atrial Fibrillation., Faizel Osman, Jeilan Mohamed, G. Andre' Ng
Internal Medicine, East Africa
Cardiac resynchronization therapy (CRT) has become an accepted treatment for selected patients with drug-resistant heart failure. Data for patients in atrial fibrillation (AF) remains limited but suggests benefit in these patients too. We report the case of an 82-year-old patient with heart failure, VVIR permanent pacemaker, and permanent AF who had an upgrade to triple-site CRT implantation with good clinical response. Triple-site ventricular pacing may enhance the chance of response and LV reverse remodeling and should be considered in AF patients undergoing CRT implantation.

The burden of coronary heart disease (CHD) is increasing at a greater rate in South Asia than in any other region globally, but there is little direct evidence about its determinants. The Pakistan Risk of Myocardial Infarction Study (PROMIS) is an epidemiological resource to enable reliable study of genetic, lifestyle and other determinants of CHD in South Asia. By March 2009, PROMIS had recruited over 5,000 cases of first-ever confirmed acute myocardial infarction (MI) and over 5,000 matched controls aged 30-80 years. For each participant, information has been recorded on demographic factors, lifestyle, medical and family history, anthropometry, and a …

Center for Translational Medicine Faculty Papers
Aldosterone produces a multitude of effects in vivo, including promotion of postmyocardial infarction adverse cardiac remodeling and heart failure progression. It is produced and secreted by the adrenocortical zona glomerulosa (AZG) cells after angiotensin II (AngII) activation of AngII type 1 receptors (AT(1)Rs). Until now, the general consensus for AngII signaling to aldosterone production has been that it proceeds via activation of G(q/11)-proteins, to which the AT(1)R normally couples. Here, we describe a novel signaling pathway underlying this AT(1)R-dependent aldosterone production mediated by beta-arrestin-1 (betaarr1), a universal heptahelical receptor adapter/scaffolding protein. This pathway results in sustained ERK activation and subsequent …

Primary Cardiac Tumors., Suraj Maraj, Md, Gregg S. Pressman, Md, Vincent M. Figueredo, Md
Division of Cardiology Faculty Papers
Primary cardiac tumors are a rare entity compared to tumors that metastasize to the heart. Patients with such tumors may be asymptomatic. Many cases are found incidentally during evaluation of an unrelated medical condition. It is important for the clinician to have a high index of suspicion when evaluating a patient presenting with signs and systemic symptoms concerning possible malignancy, plus cardiac specific symptoms or complications. These can include new onset dyspnea, congestive heart failure, arrhythmias or murmurs varying with body positions. Imaging, particularly the use of echocardiography, remains the cornerstone of diagnosis, and may be combined with new imaging …

Women with lupus are at increased risk for developing cardiovascular disease (CVD). Previous studies of atherosclerosis in SLE have not been representative of the minority groups most affected by lupus and its complications. Therefore, a study of 41 lupus cases and 83 controls was conducted to investigate the relationship between carotid atherosclerosis and inflammation in African-American women. Participation consisted of a questionnaire, physical examination, fasting blood draw, and ultrasound of the carotid arteries. There were observed differences between cases and controls with regard to carotid intima media thickness (IMT) and traditional cardiovascular risk factors, although few reached statistical significance. Tumor …

Extracardiac or genetic abnormalities (EGA) represent a factor in the morbidity of patients with congenital heart disease. We evaluated the way neonates with CHD are screened at our institution and determined the yield for the screening tests. We reviewed the charts of 223 neonates with structural CHD. Subjects were categorized into 6 groups: univentricular, left-sided obstructive lesions, right-sided obstructive lesions, septal defects, conotruncal defects (CTD), and other. We reviewed which patients underwent cranial ultrasonogram (CUS), abdominal ultrasonogram (AUS), and/or genetic studies (GS) as well as their results. There was a high prevalence of EGA in each group by CUS (32% …
Use Of Clopidogrel In The Reduction Of Myocardial Damage During Percutaneous Coronary Intervention, Arijit Dasgupta, Debabrata Mukherjee
Use Of Clopidogrel In The Reduction Of Myocardial Damage During Percutaneous Coronary Intervention, Arijit Dasgupta, Debabrata Mukherjee
Gill Heart & Vascular Institute Faculty Publications
It is estimated that approximately a quarter of patients undergoing coronary intervention may have significant post-procedural creatinine (CK)/creatinine kinase myocardial band (CK-MB) elevations and approximately half may have post-procedural troponin elevations. Current data suggest that periprocedural infarction is associated with short-, intermediate-, and long-term adverse outcomes, most notably mortality. This review examines the role of clopidogrel in decreasing periprocedural myonecrosis following percutaneous coronary intervention (PCI). Clopidogrel is an important pharmacologic agent used to reduce myocardial infarction post-coronary intervention as assessed directly by the evaluation of cardiac biomarkers and indirectly by the evaluation of short-term ischemic events. The optimal dose of …

Alcohol In Moderation, Cardioprotection And Neuroprotection : Epidemiological Considerations And Mechanistic Studies, Dipak K. Das Dr.
UCHC Articles - Research
In contrast to many years of important research and clinical attention to the pathological effects of alcohol (ethanol) abuse, the past several decades have seen the publication of a number of peer-reviewed studies indicating beneficial effects of light-moderate, non-binge consumption of varied alcoholic beverages, as well as experimental demonstrations that moderate alcohol exposure can initiate typically cytoprotective mechanisms. A considerable body of epidemiology associates moderate alcohol consumption with significantly reduced risks of coronary heart disease and, albeit currently a less robust relationship, cerebrovascular (ischemic) stroke. Experimental studies with experimental rodent models and cultures (cardiac myocytes, endothelial cells) indicate that moderate …

Scholarship and Professional Work – COPHS
Sildenafil is a phosphodiesterase 5 inhibitor widely used for the treatment of pulmonary hypertension in children. Despite limited available safety and efficacy evidence, use of sildenafil continues to increase. To date, sildenafil use for pediatric pulmonary hypertension has been characterized for 193 children through 16 studies and 28 case series and reports. The primary efficacy data suggest that sildenafil is beneficial for facilitating the weaning of inhaled nitric oxide in children after cardiac surgery. Compiled safety data suggest that sildenafil is well tolerated among children with idiopathic pulmonary arterial hypertension and pulmonary arterial hypertension associated with congenital heart disease. This …

Section of Cardiothoracic Surgery
The diagnosis of mediastinal adenopathy is a dilemma amongst treating physicians especially in South Asia. This is because although tuberculosis is endemic in this region, many a times lymphoma and sarcoidosis cannot be excluded. Often patients are being treated with medications without a confirmed diagnosis. The Video-assisted thoracoscopy (VATS) has revolutionized the way mediastinal adenopathy is diagnosed and managed in this part of the world.

Letter By Jeilan Et Al Regarding Article, "Longitudinal Strain Delay Index By Speckle Tracking Imaging: A New Marker Of Response To Cardiac Resynchronization Therapy"., Jeilan Mohamed, Jiun H. Tuan, G. Andre' Ng
Internal Medicine, East Africa
We read with interest the recent article by Lim et al.1 This article demonstrated a strong correlation between a novel longitudinal strain delay index and left ventricular end-systolic volume reduction in both ischemic and nonischemic patients.
The principle outlined by the authors is that an increased longitudinal strain delay index requires both dyssynchrony (defined in their article as a discrepancy between the time of end-systolic contraction and the time to peak strain) and residual contractility. Their concept elegantly considers the problem of cardiac resynchronization therapy (CRT) nonresponse in heart failure patients who have myocardial segments with delayed contraction due …

Despite the evidence for early fetal experience exerting programming influences on later neurological development and health risk, very few prospective studies of human fetal behavior have been reported. In a prospective longitudinal study, fetal nervous system maturation was serially assessed by monitoring fetal heart rate (FHR) responses to vibroacoustic stimulation (VAS) in 191 maternal/fetal dyads. Responses were not detected at 26 weeks gestational age (GA). Sex-specific, age-characteristic changes in the FHR response to VAS were observed by 31 weeks' GA. Males showed larger responses and continued to exhibit maturational changes until 37 weeks'GA, females however, presented with a mature FHR …

BACKGROUND: Angiotensin converting enzyme (ACE) inhibitors are known to improve clinical outcome and ventricular function in adults with heart failure. Infants with single-ventricle physiology show abnormalities in ventricular function as well as poor growth. The ability of an ACE inhibitor to preserve ventricular function and improve growth in these infants is unknown.
METHODS: The Pediatric Heart Network designed a randomized, double-blind trial to compare outcomes in infants with single-ventricle physiology receiving enalapril or placebo. Neonates < or =45 days old were eligible. The primary outcome is weight-for-age Z-score at 14 months of age. Secondary outcomes include other measures of somatic growth, laboratory and functional measures of heart failure, developmental indices, measures of ventricular size and function, and the relationship of the renin-angiotensin-aldosterone system genotype to the response to enalapril. The incidence and spectrum of adverse events will also be compared between treatment groups.
RESULTS: A total of 1,245 neonates were screened and 533 (43%) were eligible. The consent rate was 43%; 230 subjects were enrolled. Parental reluctance to …

This study was aimed to explore underlying mechanism(s) of cardiovascular effects of piperine. Intravenous administration of piperine caused a dose-dependent (1 to 10 mg/kg) decrease in mean arterial pressure (MAP) in normotensive anesthetized rats, the next higher dose (30 mg/kg) did not cause any further change in MAP. The fall in blood pressure (BP) was followed by small increase in MAP after each dose. In Langendorrf's rabbit heart preparation, piperine caused partial inhibition and verapamil caused complete inhibition of force and rate of ventricular contractions and coronary flow. In rabbit aortic rings, piperine inhibited high K(+) (80 mM) precontractions and …

With the advent of highly active antiretroviral therapy, there has been a significant change in the epidemiology of pulmonary disease in HIV/AIDS. The relative prevalence of non-infectious manifestations is likely to rise. HIV associated pulmonary hypertension (HIV-PH), albeit low prevalence, is associated with significant morbidity and mortality. Presently, despite having scanty evidence on the management modalities of HIV-PH, evidence extrapolated from idiopathic pulmonary hypertension is being utilised to effectively manage some of these patients. Efforts should therefore be made to screen, diagnose and treat these patients. A case of a thirty year old female with HIV disease and severe pulmonary …
