非Q波心肌梗塞(MI)后再梗塞的发生率高于Q波MI,且再梗塞对左室功能和生存率均有不利影响。本文评价地尔硫对非Q波MI患者再梗塞及其后死亡率的影响。方法在多中心地尔硫心肌梗塞后研究中的2466例患者中,除外需行冠脉搭桥术和服用钙拮抗剂者,以及心电图(ECG)示异常Q波者,共有514例非Q波MI患者进入本研究。所有患者在MI后3～15天内随机分入地尔硫(D)组或安慰剂(P)组,其中D组 The incidence of reinfarction after Q-MI was higher than Q-wave MI, and reinfarction had adverse effects on left ventricular function and survival. This article evaluates the effect of diltiazem on reinfarction and subsequent mortality in non-Q-wave MI patients. Methods Among the 2466 patients who underwent multicentre Sulfartar after myocardial infarction, excluding coronary artery bypass (CABG) and calcium channel blockers, and ECG-abnormal Q waves, there were 514 non-Q waves MI patients entered the study. All patients were randomly assigned to diltiazem (D) or placebo (P) within 3 to 15 days after MI, with group D
