BACKGROUND The Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial showed that apixaban is better than warfarin at prevention of stroke or systemic embolism, causes less bleeding, and results in lower mortality. We assessed in this trial's participants how results differed according to patients'… (More)
BACKGROUND Cardiac resynchronization therapy with defibrillator (CRT-D) reduces morbidity and mortality among selected patients with heart failure in clinical trials. The effectiveness of this therapy in clinical practice has not been well studied. METHODS AND RESULTS We compared a cohort of 4471 patients from the National Cardiovascular Data Registry's… (More)
BACKGROUND Implantable cardioverter-defibrillator (ICD) therapy is associated with improved outcomes in patients with heart failure (HF), but whether this association holds among older patients with multiple comorbid illnesses and worse HF burden remains unclear. METHODS AND RESULTS Using the National Cardiovascular Data Registry's ICD Registry and the… (More)

AIMS History of bleeding strongly influences decisions for anticoagulation in atrial fibrillation (AF). We analyzed outcomes in relation to history of bleeding and randomization in ARISTOTLE trial patients. METHODS AND RESULTS The on-treatment safety population included 18,140 patients receiving at least 1 dose of study drug (apixaban) or warfarin.… (More)
A trial fibrillation (AF) is a global health problem. The condition brings an increased risk of stroke, systemic embolism, and heart failure (HF) and is associated with impaired quality of life, frequent hospitalizations, and mortality. 1 Observational studies have been the main source of information for many years and have defined the clinical… (More)
BACKGROUND Conveying contemporary treatment options for those at risk of sudden cardiac arrest (SCA) is challenging. The purpose of the present research was to evaluate the quality and usability of available patient educational tools relevant to SCA and its treatment options, such as implantable cardioverter defibrillators (ICDs). We hypothesized that this… (More)
