本文对５６１例急性心肌梗塞（ＡＭＩ）患者进行１０年回顾性调查。心功能不全的发生率为４６．３５％，其中９５例用过洋地黄类药物，应用该药后对心室率减慢（Ｐ＜０．０１）、改善心功能不全（Ｐ＜０．０１）有效，并对并发有房颤、房扑及阵发性室上速患者治疗也有效。用药后近期未发现有严重心律失常及梗塞面积的扩大。洋地黄类药物组病死率为４１．０２％；对照组为２０．７６％。病死率的高低与心功能程度成正相关。
In this paper, 561 patients with acute myocardial infarction (AMI) were retrospectively investigated for 10 years. The incidence of heart failure was 46.35%, of which 95 cases had been treated with digitalis, the ventricular rate was decreased (P <0.01) and heart failure was improved (P <0.01) Effective, and concurrent with atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia treatment is also effective. Recently found no serious arrhythmia and infarct size expansion. Digitalis drug group mortality was 41.02%; control group was 20.76%. The level of mortality is positively correlated with the degree of cardiac function.
