Objectives: Frailty is associated with adverse outcomes, but little is known of the impact of frailty on patients with implantable cardioverter defibrillators (ICDs). This study sought to determine the prevalence of frailty, based on quantitative assessment, and assessed its potential impact on outcomes among community-dwelling men with ICDs. Methods: A…
Objectives: Obscure overt gastrointestinal bleeding can be challenging to evaluate in patients with electronic cardiac devices such as continuous flow left ventricular assist devices (LVADs), pacemakers (PPMs), and implantable cardioverter defibrillators (ICDs). Limited data exist on the utility and safety of single balloon enteroscopy (SBE) in patients with cardiac devices….
Objectives: Gas exchange measurements obtained during submaximal exercise have been shown to provide prognostic and diagnostic information in patients with heart failure (HF) and to differentiate heart versus lung limitations in patients with unexplained dyspnea. The aim of our study was to assess the clinical utility of submaximal cardiopulmonary exercise…
Sudden cardiac death (SCD) due to ventricular tachyarrhythmias is a leading cause of death in the United States. Various etiologies, including ischemic and nonischemic cardiomyopathies, hypertrophic cardiomyopathy, valvular or congenital heart diseases and other less common disorders, may result in SCD. Beta blockers are the only class of medications that…
This report describes a 42-year-old man with Brugada syndrome (BRS) mimicking acute coronary syndrome. Chest pain, near-syncope, and electrocardiographic changes were thought initially to be due to ischemia. Cardiac catheterization was performed. The coronary arteries and left ventricular function were normal. Careful review of his electrocardiogram suggested a diagnosis of…
