Epicardial fat is a metabolically active fat depot that is strongly associated with obesity, metabolic syndrome, and coronary artery disease (CAD). The relation of epicardial fat to diastolic function is unknown. We sought to (1) understand the relation of epicardial fat volume (EFV) to diastolic function and (2) understand the role of EFV in relation to(More)
BACKGROUND Diastolic dysfunction is an independent predictor of mortality in patients with normal left ventricular ejection fraction. There are limited data, however, on whether worsening of diastolic function is associated with worse prognosis. METHODS AND RESULTS We reviewed clinical records and echocardiograms of consecutive patients who had baseline(More)

BACKGROUND Rhythm control with antiarrhythmic drugs (AADs) is not superior to rate control in patients with heart failure (HF) and atrial fibrillation (AF), but AF ablation may be more successful at achieving rhythm control than AADs. However, risks for both ablation and AADs are likely higher and success rates lower in patients with HF. OBJECTIVE To(More)
OBJECTIVES The study sought to investigate whether there is stress-induced worsening of left ventricular mechanical dyssynchrony (LVMD) in patients with ischemic cardiomyopathy (ICM), determine the predictors of LVMD response (LVMDR) and its incremental prognostic value. BACKGROUND The effect of stress physiology on LVMD in patients with ICM has not been(More)
BACKGROUND The aim of our study was to compare myocardial mechanics of constrictive pericarditis (CP) with restrictive cardiomyopathy (RCM), or healthy controls; to assess the impact of pericardial thickening detected by cardiac magnetic resonance on regional myocardial mechanics in CP; and to quantitate the effect of pericardiectomy on myocardial mechanics(More)
BACKGROUND Although impaired left ventricular (LV) filling in constrictive pericarditis (CP) is attributable to external constraints by a tethered pericardium, impaired left atrial (LA) function can further impair LV filling. Previous studies focused on the impact of a tethered pericardium on LV diastolic behavior, but its impact on LA function has been(More)
There are limited data on whether differences exist in left ventricular (LV) mechanical dyssynchrony indices derived from stress versus rest gated positron emission tomography (PET) in patients with normal myocardial perfusion imaging (MPI). Stress/rest 82Rb gated PET was performed in consecutive patients with normal MPI between 2006 and 2010. Patients were(More)
The safety of regadenoson (Reg) during low-level exercise testing has been established. However, its administration at peak exercise for patients who do not reach target heart rate (THR) on standard exercise treadmill stress testing (ETT) needs to be established, particularly among patients with known coronary artery disease (CAD) From our stress myocardial(More)
