Incidence Of, Predictors For, And Mortality Associated With Malignant Ventricular Arrhythmias In Non-St Elevation Myocardial Infarction Patients., Shuchita Gupta, Md, Gregg S. Pressman, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

BACKGROUND: The incidence of non-ST elevation myocardial infarction (NSTEMI) is increasing. Although life-threatening ventricular arrhythmias have been well-documented in patients with ST elevation MI (STEMI), their incidence and importance in NSTEMI have not been examined in similar detail. We examined the incidence, predictors, and mortality rates of ventricular arrhythmias in a cohort of NSTEMI patients undergoing an early invasive strategy.

METHODS: Consecutive patients admitted with NSTEMI who underwent cardiac catheterization within 48 h of admission were identified by chart review. Presence and type of ventricular arrhythmias and 30-day mortality were recorded. Malignant arrhythmias were defined as sustained ventricular tachycardia (VT, …

Distribution Of Left Ventricular Ejection Fraction In Angina Patients With Severe Coronary Artery Disease Not Amenable To Revascularization., Shuchita Gupta, Gregg S. Pressman, D Lynn Morris, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

BACKGROUND: As the number of angina patients with severe coronary artery disease not amenable to revascularization increases, new therapies will be developed. How patients with depressed compared to normal left ventricular ejection fraction (LVEF) will respond to new therapies may differ.

HYPOTHESIS: We conducted a retrospective chart review to determine the distribution of LVEF in angina patients with severe coronary artery disease (three-vessel disease with >50% stenosis major epicardial vessels or >50% stenosis left main) not amenable to revascularization.

METHODS: Patients underwent cardiac catheterization between 2004 and 2009. LVEF, measured by echocardiography, nuclear-gated imaging or radioventriculography within 6 months of …

Body Mass Index, Treatment Practices, And Mortality In Patients With Acute Heart Failure, Timothy Fitzgibbons, Olga Hardy, Darleen Lessard, Joel Gore, Jorge Yarzebski, Robert Goldberg

OBJECTIVES: Obesity is associated with an increased risk of heart failure (HF). Among patients presenting with acute HF, however, differences in clinical characteristics, treatment regimens, and short-term prognosis of varying weights are largely unknown, particularly from a broader population-based perspective. METHODS: A total of 3722 patients admitted with acute HF to 11 greater Worcester (Massachusetts, USA) hospitals during 1995 and 2000 were categorized as being lean (n = 216), normal weight (n = 1465), overweight (n = 1007), or obese (n = 1034) at the time of hospitalization. RESULTS: Obese patients with decompensated HF were significantly younger (mean age = …
