Increased Risk of Heart Failure in Elderly Patients Treated with Beta-Blockers After AV Node Ablation.

Introduction: Controversy exists regarding the indication of beta-blockers (BB) in different scenarios in patients with cardiovascular disease. We sought to evaluate the effect of BB on survival and heart failure (HF) hospitalizations in a sample of pacemaker-dependent patients after AV node ablation to control ventricular rate for atrial tachyarrhythmias.

Methods: A retrospective study including consecutive patients that underwent AV node ablation was conducted in a single center between 2011 and 2019.
