Use Of Clopidogrel In The Reduction Of Myocardial Damage During Percutaneous Coronary Intervention, Arijit Dasgupta, Debabrata Mukherjee Mar 2009

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 …

ABSTRACT: BACKGROUND: Circadian (diurnal) rhythm is an integral part of the physiology of the body; specifically, sleep, feeding behavior and metabolism are tightly linked to the light-dark cycle dictated by earth's rotation. METHODS: The present study examines the effect of diurnal rhythm on gene expression in the subcutaneous adipose tissue of overweight to mildly obese, healthy individuals. In this well-controlled clinical study, adipose biopsies were taken in the morning, afternoon and evening from individuals in three study arms: treatment with the weight loss drug sibutramine/fasted, placebo/fed and placebo/fasted. RESULTS: The results indicated that diurnal rhythm was the most significant driver …


Alcohol In Moderation, Cardioprotection And Neuroprotection : Epidemiological Considerations And Mechanistic Studies, Dipak K. Das Dr. Feb 2009

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 …

Sildenafil For The Treatment Of Pulmonary Hypertension In Pediatric Patients, Alice J. Huddleston, Chad A. Knoderer, Jennifer L. Morris, Eric S. Ebenroth

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 …

Dilemma In The Diagnosis Of Mediastinal Adenopathy In The South Asian Population-Role Of Ct Guided Biopsy, Mediastinoscopy And Video-Assisted Thoracoscopy (Vats), Marium Muzaffar, Hashim M Hanif, Saulat H. Fatimi

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.

Manuscripts, Articles, Book Chapters and Other Papers

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 …

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 Jan 2009

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 …

Abstract

Introduction

X-linked adrenoleukodystrophy leads to demyelination of the nervous system, adrenal insufficiency, and accumulation of long-chain fatty acids. Most young patients with X-linked adrenoleukodystrophy develop seizures and progressive neurologic deficits, and die within the first two decades of life. Congenital or acquired disorders of the respiratory system have not been previously described in patients with X-linked adrenoleukodystrophy.

Case presentation

A 3-year-old Arabic boy from Yemen presented with discoloration of the mucous membranes and nail beds, which were considered cyanoses due to methemoglobinemia. He also had shortness of breath, fatigue, emesis and dehydration episodes for which he was admitted to …

Psychology Faculty Articles and Research

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 …

Fatal Transfusion Related Acute Lung Injury Following Coronary Artery By-Pass Surgery: A Case Report., Fauzia Ahmad Bawany, Hasanat Sharif

Section of Cardiothoracic Surgery

Background:Transfusion related acute lung injury (TRALI) is a potentially fatal Acute Lung Injury following transfusion of blood components. Hypotheses implicate donor-derived anti-human leukocyte antigen or granulocyte antibodies reacting with recipients' leukocytes, releasing inflammatory mediators. Lack of agreement on underlying cellular and molecular mechanisms renders improving transfusion safety difficult and expensive.

Case Presentation:

Literature search has not revealed any case of TRALI from Pakistan. We report the case of fatal TRALI in a 68 year old male who received blood products after coronary artery by-pass surgery.

Conclusion:

This article aims to create awareness about this complication and suggests that post …

Department of Biological & Biomedical Sciences

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 …


Hiv-Associated Pulmonary Hypertension: Case Report, Jay Shavadia, S. Das, Gerald Yonga Nov 2008

Hiv-Associated Pulmonary Hypertension: Case Report, Jay Shavadia, S. Das, Gerald Yonga

Internal Medicine, East Africa

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 …

Center for Translational Medicine Faculty Papers

Based on extensive preclinical data, glycogen synthase kinase-3 (GSK-3) has been proposed to be a viable drug target for a wide variety of disease states, ranging from diabetes to bipolar disorder. Since these new drugs, which will be more powerful GSK-3 inhibitors than lithium, may potentially be given to women of childbearing potential, and since it has controversially been suggested that lithium therapy might be linked to congenital cardiac defects, we asked whether GSK-3 family members are required for normal heart development in mice. We report that terminal cardiomyocyte differentiation was substantially blunted in Gsk3b(-/-) embryoid bodies. While GSK-3alpha-deficient mice …

OBJECTIVE: The initial palliative procedure for patients born with hypoplastic left heart syndrome and related single right ventricle anomalies, the Norwood procedure, remains among the highest risk procedures in congenital heart surgery. The classic Norwood procedure provides pulmonary blood flow with a modified Blalock-Taussig shunt. Improved outcomes have been reported in a few small, nonrandomized studies of a modification of the Norwood procedure that uses a right ventricle-pulmonary artery shunt to provide pulmonary blood flow. Other nonrandomized studies have shown no differences between the two techniques.

METHODS: The Pediatric Heart Network designed a randomized clinical trial to compare outcomes for …

The Dose-Response Of Nitrous Oxide In Postoperative Nausea In Patients Undergoing Gynecologic Laparoscopic Surgery: A Preliminary Study., Boris Mraovic, Tatjana Simurina, Zdenko Sonicki, Neven Skitarelic, Tong J. Gan

Department of Anesthesiology Faculty Papers

BACKGROUND: Whether nitrous oxide (N(2)O) increases the incidence of postoperative nausea and vomiting (PONV) after laparoscopic gynecologic surgery is still controversial, which may be due to the administration of different concentrations of inspired N(2)O. We investigated whether N(2)O results in a dose-response increase in PONV. METHODS: Patients undergoing gynecologic laparoscopic surgery were randomized to receive 30% oxygen with air (G0, n = 46), 50% N(2)O with oxygen (G50, n = 46), or 70% N(2)O with oxygen (G70, n = 45). A standardized general anesthetic was used with no PONV prophylaxis. Known risk factors for PONV were controlled. Metoclopramide was used …
