OBJECTIVES: We evaluated the effect of angiotensin-converting enzyme (ACE) inhibitor ramipril on the incidence of atrial fibrillation (AF) in patients enrolled in the Heart Outcomes Prevention Evaluation trial. BACKGROUND: Atrial fibrillation is the most common arrhythmia affecting the general population and is associated with increased morbidity and mortality. Retrospective secondary analyses of some of the large trials of ACE inhibitors have suggested that ACE inhibitors may prevent AF. METHODS: We evaluated the occurrence of AF by reviewing the electrocardiogram tracings at entry, at 2 years, and at the end of the study, as well as hospitalizations among 8335 high-risk participants from the Heart Outcomes Prevention Evaluation study, > or = 55 years, without known heart failure or left ventricular (LV) systolic dysfunction and followed for a median period of 4.5 years. We compared the impact of ramipril and matched placebo on occurrence of AF. The results were compared to similar trials. RESULTS: Over the 4.5 years follow-up, the incidence of new AF was low (2.1%, 177/8335), and ramipril did not significantly reduce the rate of new AF compared with placebo (86/4291 [2.0%] vs 91/4044 [2.2%]) with an odds ratio of 0.92 (95% confidence interval, 0.68-1.24; P = .57). These results added to the previous ACE inhibitor trials (excluding trials in patients with LV dysfunction) showed no significant reduction in new AF among patients treated with these agents (1088/20,930 [5.0%] vs 1343/22,878 [5.9%]; relative risk, 0.92; 95% confidence interval, 0.80-1.05). CONCLUSION: Although the incidence of AF was low, treatment with ramipril in this population without known LV systolic dysfunction did not significantly reduce this dysrhythmia.
