Descriptive Information
Brief Title ICMJE	Genetically Targeted Therapy for the Prevention of Symptomatic Atrial Fibrillation in Patients With Heart Failure
Official Title ICMJE	GENETIC-AF - A Genotype-Directed Comparative Effectiveness Trial of Bucindolol and Toprol-XL for Prevention of Symptomatic Atrial Fibrillation/Atrial Flutter in Patients With Heart Failure
Brief Summary	This study is being done to compare the effects of bucindolol hydrochloride (bucindolol) to metoprolol succinate (Toprol-XL) on the recurrence of symptomatic atrial fibrillation/atrial flutter in patients with heart failure who have a specific genotype for the beta-1 adrenergic receptor.
Detailed Description	The goal of the GENETIC-AF trial is to demonstrate the superiority of pharmacogenetically targeted bucindolol compared to metoprolol for the prevention of symptomatic atrial fibrillation or atrial flutter in a genotype-defined population with heart failure and/or reduced left ventricular ejection fraction at high risk of atrial fibrillation/atrial flutter recurrence.
