Aim: To determine by meta‐analysis whether angiotensin‐converting enzyme (ACE) inhibitors improve exercise tolerance in patients with symptomatic left ventricular systolic dysfunction (LVSD). Methods and results: After literature search 13 multi‐centre double blind parallel group trials that evaluated the effect of ACE inhibitors vs. placebo on exercise duration were selected. Ninety‐four percent of patients were in New York Heart Association class II–IV. The studies were combined using the Cochrane meta‐analysis program (Review manager version 4.1). Analyses according to treatment period, exercise protocols and publication periods were performed. Treatment with ACE inhibitor over 4–12 weeks resulted in a beneficial effect on exercise duration ( P= 0.003 and P= 0.0008 for 4‐ and 12‐weeks treatment, respectively), but the magnitude of improvements did not exceed 30 s corresponding to only 5% compared with placebo. Conclusion: In addition to the pronounced effect on mortality and morbidity in patients with symptomatic LVSD, ACE inhibitors have improving effect on functional capacity measured as exercise tolerance time.
