The impact of beta-blocker use on postoperative atrial fibrillation after aortic valve replacement.

ABSTRACT:

Background

Current guidelines recommend perioperative use of beta-blocker (BB) in patients undergoing cardiac surgery to prevent postoperative atrial fibrillation (POAF). However, this recommendation is mainly based on studies those exclusively enrolled patients undergoing coronary artery bypass grafting. This study was conducted to evaluate the impact of perioperative BB use on the occurrence of POAF after aortic valve replacement (AVR).

Methods

From January 2015 to June 2018, 296 patients (male: female = 163:133) who underwent AVR at our institution were retrospectively reviewed. Patients who underwent concomitant valve surgery other than AVR or patients with preoperative arrhythmia were excluded. Mean age at the operation was 67±12 years. All patients were continuously te
