Ghrelin Receptor Deficiency Does Not Affect Diet-Induced Atherosclerosis In Low-Density Lipoprotein Receptor-Null Mice, Kirk M. Habegger, Erin Grant, Paul Thomas Pfluger, Diego Perez-Tilve, Alan Daugherty, Dennis Bruemmer, Matthias H. Tschöp, Susanna M. Hofmann

Saha Cardiovascular Research Center Faculty Publications

OBJECTIVE: Ghrelin, a stomach-derived, secreted peptide, and its receptor (growth hormone secretagogue receptor, GHSR) are known to modulate food intake and energy homeostasis. The ghrelin system is also expressed broadly in cardiovascular tissues. Since ghrelin has been associated with anti-inflammatory and anti-atherogenic properties, but is also well known to promote obesity and impair glucose metabolism, we investigated whether ghrelin has any impact on the development of atherosclerosis. The hypothesis that endogenous ghrelin signaling may be involved in atherosclerosis has not been tested previously.

METHODS AND RESULTS: We crossed ghrelin receptor knockout mice (GHSr^-/-) into a low-density lipoprotein receptor-null …

Effect Of Percutaneous Mitral Vavuloplasty On Pregnant Mother And Foetus--A Tertiary Care Hospital Experience From A Developing Country, Syed Haider Imam, Abbas Haider Zaidi, Sana Shoukat, Sajid H. Dhakam

Section of Cardiology

This study evaluated the short and long-term consequences of Percutaneous Mitral Valvuloplasty (PMV) in pregnant patients and their offspring, in a tertiary care setting, Karachi, Pakistan. The hospital database was used to retrieve all patients who underwent PMV during pregnancy in the period 1998-2007. The follow up data of the patients and the born children were obtained from the hospital records and also by contacting the patients via phone. Six patients underwent PMV but follow-up was available for 5 patients only. All 5 patients were admitted due to severe mitral stenosis with symptoms of dyspnea and palpitation. Mean age was …

Predictors Of Appropriate Defibrillator Therapies- A Single Center Analysis, Rina R. Shah, Ratika Gupta, Carrie Stackhouse, Robin Ward, Behzad B. Pavri

Division of Cardiology Faculty Papers

Discussion:

• Although differences in HR and the JT interval were statistically significant in patients who received appropriate shock vs. those who did not, these differences are not clinically meaningful
• We did not identify any clinical predictors of early vs. late ICD shocks
• These data suggest that we may not be able to improve on current guidelines for patient selection for ICD implantation.

Objectives: Glycemic variability increases oxidative stress and may trigger the inflammation and coagulation cascades. Variability may be associated with increase morbidity and mortality in ICU patients. We analyzed glycemic variability after major surgery in diabetic (DM) and non-diabetic (NDM) patients using an automated intravenous blood glucose monitor (IVBG).

The Prevalence And Risk Factors Of Acute Myocardial Infarction (Ami) After Acute Ischemic Stroke (Ais) In The United States, Ali Seifi, Md, Fred Rincon, Md, Msc, Michael Moussouttas, Md, Mitchell Maltenfort, Phd, Matthew Vibbert, Md, Rodney Bell, Md, Maria Carissa Pineda, Md, Diana Tzeng, Md, Jacqueline Urtecho, Md, Anish Koka, Md, William Mcbride, Md

Objectives: To determine the prevalence and risk factors for, and the association with in-hospital mortality of, AMI after AIS, and to study the effect of intravenous recombinant tissue plasminogen activator (r-tPA) in this setting. We hypothesized that AMI would be associated with lower survival rate at hospital discharge but that intravenous r-tPA would be associated with lower risk of AMI.

BACKGROUND: Complex anatomy and limited windows complicate echocardiographic assessments of ventricular function in Fontan patients. For the Pediatric Heart Network Fontan Cross-Sectional Study, data were acquired from which mean ventricular pressure change during isovolumetric contraction (dP/dt(ic)), Tei index, and maximal systolic annular velocity (S') could be measured. The purpose of this study was to compare these nongeometric indices of ventricular function to cardiac magnetic resonance (CMR) measurements of ventricular ejection fraction (EF).

METHODS: Echocardiographic and CMR studies were performed prospectively using standardized protocols; measurements were completed by core laboratories. Data from both modalities were available from 137 patients.

RESULTS: A …

Mother And Child Technique Combined With Super Selective Pharmacological Intervention For Large Intracoronary Thrombus, Nasir Rahman, Sajid H. Dhakam

Section of Cardiology

Primary percutaneous intervention (PCI) in acute ST elevation myocardial infarction (MI) is a preferred way of treatment nowadays. Sometimes it becomes difficult to get good myocardial blood flow during PCI if clot burden is large. In this case of an elderly lady, the use of "Mother and Child Technique" combined with super selective pharmacological intervention is demonstrated to achieve good blood flow when conventional means are not working.

Alcoholic Cardiomyopathy: A Review., Anil George, Vincent M Figueredo

Division of Cardiology Faculty Papers

Alcohol abuse can cause cardiomyopathy indistinguishable from other types of dilated nonischemic cardiomyopathy. Most heavy drinkers remain asymptomatic in the earlier stages of disease progression, and many never develop the familiar clinical manifestations that typify heart failure. We review the current thinking on the pathophysiology, clinical characteristics, and treatments available for alcoholic cardiomyopathy. The relationship of alcohol to heart disease is complicated by the fact that in moderation, alcohol has been shown to afford a certain degree of protection against cardiovascular disease.

Advanced Glycation End Products Accelerate Ischemia/Reperfusion Injury Through Receptor Of Advanced End Product/Nitrative Thioredoxin Inactivation In Cardiac Microvascular Endothelial Cells., Yi Liu, Yanzhuo Ma, Rutao Wang, Chenhai Xia, Rongqing Zhang, Kun Lian, Ronghua Luan, Lu Sun, Lu Yang, Wayne B Lau, Haichang Wang, Ling Tao

Department of Emergency Medicine Faculty Papers

The advanced glycation end products (AGEs) are associated with increased cardiac endothelial injury. However, no causative link has been established between increased AGEs and enhanced endothelial injury after ischemia/reperfusion. More importantly, the molecular mechanisms by which AGEs may increase endothelial injury remain unknown. Adult rat cardiac microvascular endothelial cells (CMECs) were isolated and incubated with AGE-modified bovine serum albumin (BSA) or BSA. After AGE-BSA or BSA preculture, CMECs were subjected to simulated ischemia (SI)/reperfusion (R). AGE-BSA increased SI/R injury as evidenced by enhanced lactate dehydrogenase release and caspase-3 activity. Moreover, AGE-BSA significantly increased SI/R-induced oxidative/nitrative stress in CMECs (as measured …

A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo

Paulo A Lotufo

Background: Brazil has the highest cerebrovascular death rate in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes. Methods: We analysed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by sex and age (35–74 y). The annual percent change (APC) and significant changes in the trends were identified with joinpoint Poisson regression. The average annual percent change (AAPC) for 2005-09 was presented because that period had the best quality of information. Results: After excluding deaths due to stroke sequels, for men, the APCs (95% confidence intervals) were: 1979-84: 0.7 (-0.8 to …
