本文目的不在于重复叙述梗死前驱症群及对它的疗法,而在于研究这一前驱症群对于初发的心肌梗死短期病程演变有何影响。按YuPN诊断梗死前驱症群的标准(其标准为:1.胸骨后憋闷感或疼痛:a.发作频率及严重性不断增加,b.通常与劳累无关,c.对休息和亚硝酸类药效应改变或无效应;2.有心肌缺血的心电图表现;3.缺少心肌坏死的心电图或血清酶变化的证据;4.近期内有发展成急性心肌梗死的可能。)将住院的初发心肌梗死病人333例分为两组。A组为有前驱症群表现者149例(男92,女57),B组为无前驱症群表
The purpose of this article is not to repeat the description of the group of infarction and its treatment, but to study the impact of this predominant group on the short-term course of the initial myocardial infarction. According to YuPN diagnosis of infarction predominate group standards (the criteria are: 1. Feeling or pain after the sternum: a. The frequency and severity of seizures increased, b. Usually unrelated to fatigue, c. Rest and nitrous acid effects Change or no effect; 2. Electrocardiogram with myocardial ischemia; 3. Evidence of electrocardiographic or serum enzyme changes that lack myocardial necrosis; 4. Recent development of acute myocardial infarction is possible.) The hospitalized primary myocardial infarction 333 patients were divided into two groups. 149 patients (group A, group B) had precursor disorder group (male 92, female 57), group B
