对β—阻滞剂长期应用能否降低心肌梗塞(MI)后的猝死率颇有争论。此种不恒定的结果究竟是由于病例的选择,样本的大小和药物应用时间长短的不同;还是β—阻滞剂的药理特性所致,一直不太清楚。本试验研究的目的是观察“高度危险”的MI患者应用心得安治疗一年能否降低其死亡率。 病例选择与方法:从1977年12月起至1980年7月30止,在挪威120万居民区的12所医院的重点监
Long-term use of beta-blockers has led to controversy over the ability to reduce the rate of sudden death after myocardial infarction (MI). Whether such a constant result is due to the choice of case, the size of the sample and the length of time the drug is used, or the pharmacological nature of the β-blocker, remains unclear. The purpose of this pilot study was to observe if propranolol can reduce its mortality rate in patients with “high-risk” MI for one year. Case Selection and Methods: From December 1977 until July 30, 1980, the focus of supervision in 12 hospitals in 1.2 million inhabitants of Norway
