Effect of preoperative angiotensin converting enzyme inhibitor or angiotensin receptor blocker use on the frequency of atrial fibrillation after cardiac surgery: a cohort study from the atrial fibrillation suppression trials II and III

Abstract

Although preoperative ACEI or ARB use reduced the odds of developing POAF by 29%, this association with not found to be statistically significant. A study with approximately 600 subjects would be needed to discern if ACEIs or ARBs truly impact POAF.
