摘要

Since their introduction into clinical use several decades ago, the beta blockers have proven enormously successful anti- ischemic, anti-hypertensive and anti-arrhythmic agents. They have been especially useful in improving morbidity and mortality after acute myocardial infarctions (MI). The results of the placebo-controlled Norwegian Multicenter Study (with timolol), the American Beta Blocker Heart Attack Trial (BHAT; with propra-nolol), and the Goteborg Metoprolol Trial, showed for the first time that medical treatment started after onset of MI can decrease total mortality. The timolol and propranolol studies, which were started 1-2 weeks after onset of acute MI and had a follow-up of approximately 2 years, showed a reduction in total mortality of 36% and 26%, respectively. In the Goteborg Metoprolol Trial, in which the beta blocker was given to patients with suspected acute MI shortly after hospital arrival, mortality at 3 months was decreased by 36%. Many other small studies have also been published, and today data are available from 24 long-term trials that included approximately 25,000 patients. The average reduction in mortality in these trials was approximately 20% over about 2 years of follow-up.
