OBJECTIVE: Acute myocardial infarction (AMI) remains a major cause of death and beta-blockers are known to reduce long-term mortality in post-AMI patients. We sought to determine whether patients receiving beta-blockers acutely (within 72 h) following AMI had a lower mortality rate at 6 weeks than patients receiving placebo. METHODS: We conducted a systematic review of randomized controlled clinical trials that assessed 6-week mortality and compared beta-blockers with placebo in patients randomized within the first 72 hours following AMI. We searched these databases: MEDLINE (1966-2006), EMBASE (1980-2007), Cochrane Central Register of Controlled Trials, Health Star (1966-2007), Cochrane Database for Systematic Reviews, ACP Journal Club (1991-2007), Database of Abstracts of Reviews of Effect (< 1st quarter 2007) and Conference Papers Index (1984-2007). Two blinded reviewers extracted the data and rated study quality using the Jadad score and the adequacy of allocation concealment score
