ACE-inhibitor therapy after myocardial infarction--a new treatment strategy.
Potential benefit or harm of drug therapy in patients with chronic congestive heart failure and those later presenting to hospital after an acute myocardial infarction (AMI) have been studied in a number of large-scale survival studies during the last few decades. Currently available data are reviewed in order to consider both methodology and also the clinical relevance of findings with emphasis on trials with ACE-inhibitors like CONSENSUS-II, the ISIS-4, GISSI-3 and Chinese mega-trials, TRACE, SAVE and AIRE. Results of SAVE and AIRE show a clear survival benefit for the patients. Furthermore, the benefit of both trials was in addition to any other benefit which resulted from aspirin, thrombolytic and beta-blocker therapies. In absolute terms, treatment of 1,000 patients with ramipril (AIRE) for 1 year would be expected to result in the prevention/delay of 40 premature deaths. The beneficial effects of ramipril were clearly apparent by 30 days though additional benefit beyond this point was also present. Furthermore, prespecified subgroup analysis revealed significant benefit for patients at risk like women and the elderly. A selective approach is argued for the treatment of patients with ACE-inhibitors after myocardial infarction.
