室性心律失常是心肌梗死(MI)后病人死亡的主要原因,伴左室功能不全者尤其如此。既往多种药物抗心律失常试验表明,这些药物均未能降低死亡率反使死亡率增加。胺碘酮是一种强力抗心律失常药,具有多种有益效应,多项小样本研究证实有益。为评价胺碘酮对MI后左室功能减退病人总死亡 Ventricular arrhythmias are the major cause of death of patients after myocardial infarction (MI), especially with LV dysfunction. Previous anti-arrhythmic trials of various drugs have shown that none of these drugs reduced mortality and increased mortality. Amiodarone, a potent anti-arrhythmic drug, has several beneficial effects and many small sample studies have proven beneficial. To assess the total mortality of amiodarone patients with MI after left ventricular dysfunction
