以往硝酸甘油禁用于急性心肌梗塞。近年来却认为口服、舌下含化或静注硝酸甘油可产生良好的血流动力学效应。特别在左心衰时疗效更佳。它可降低左室充盈压,增加心排出量,缩小梗塞面积,降低早期病死率。动物试验还证明硝酸甘油可提高室颤阀,故推论司用于室性心律失常的治疗。本文通过前瞻性随机试验旨在评价硝酸甘油治疗急性心肌梗塞并发室性早搏的效果。
In the past, nitroglycerin was banned in acute myocardial infarction. In recent years, it is believed that oral, sublingual or intravenous nitroglycerin can produce good hemodynamic effects. Especially in the left heart failure better. It can reduce left ventricular filling pressure, increase cardiac output, reduce infarct size and reduce early mortality. Animal experiments also show that nitroglycerin can increase the ventricular fibrillation valve, so inference division for the treatment of ventricular arrhythmias. This prospective randomized trial aimed to evaluate the efficacy of nitroglycerin in the treatment of acute myocardial infarction complicated by premature ventricular contractions.
