Abstract

Background:

The present study investigated whether preoperative angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) use affected the incidence of postoperative atrial fibrillation (POAF) in patients undergoing off-pump coronary artery bypass graft (OPCAB).

Hypothesis:

Preoperative use of ACEI or ARB was related to POAF in patients undergoing OPCAB.

Methods:

This retrospective, observational, cohort study involved 1050 patients who underwent OPCAB from January 2006 to December 2009.

Results:

ACEI or ARB, ACEI alone, and ARB alone did not exert beneficial effect on the occurrence of POAF, and ACEI or ARB use was rather associated with an increased incidence of POAF (ACEI or ARB: odds ratio [OR]: 1.66, 95% confidence interval [CI]: 1.04–2.62, P = 0.03; ACEI alone: OR: 1.30, 95% CI: 0.57–2.97, P = 0.53; ARB alone: OR: 1.57, 95% CI: 0.93–2.64, P = 0.09).

Conclusions:

ACEI or ARB, ACEI alone, and ARB alone did not favorably influence the occurrence of POAF in patients undergoing OPCAB. © 2011 Wiley Periodicals, Inc.
