最近,Ovize等认为临床上急性心肌梗塞(AMI)前多次发作心绞痛可使心肌缺血处于适应性状态,而国内则很少报告。为此我们观察分析了1988年1月～1994年12月住院的98例AMI患者,从临床方面探索心肌梗塞(MI)前有无心肌缺血性适应(MIP)对MI面积及近期预后的影响。 1 资料和方法 1.1 临床资料 所收集98例首次AMI,均符合WHO诊断标准。且入院后反复查心肌酶,包括肌酸激酶(CK)、谷草转氨酶(GOT)和乳酸脱氢酶(LDH)等,均符合AMI的特征性改变。其中男69例,女29例,年龄47～86岁,平均66±8.89岁。A组62例:即AMI前有心绞痛史或经心电图、包括动态心电图检查有心肌缺血性表现,病程2天～10年,但多为1个月～2年,占
Recently, Ovize et al. Concluded that multiple episodes of angina pectoris prior to clinical acute myocardial infarction (AMI) may cause myocardial ischemia to be adaptive, whereas seldom reported in China. To this end, we observed and analyzed 98 AMI patients hospitalized from January 1988 to December 1994 to investigate the clinical effect of myocardial ischemic adaptation (MIP) on the area and immediate prognosis of MI before myocardial infarction (MI) . 1 Materials and Methods 1.1 Clinical data collected 98 cases of the first AMI, are in line with WHO diagnostic criteria. Cardiac enzymes, including creatine kinase (CK), aspartate aminotransferase (GOT) and lactate dehydrogenase (LDH), were repeatedly examined after admission, which were in accordance with the characteristic changes of AMI. There were 69 males and 29 females, aged from 47 to 86 years, with an average of 66 ± 8.89 years. A group of 62 patients: the history of angina or ECG before AMI, including dynamic ECG examination of myocardial ischemia, the duration of 2 days to 10 years, but mostly 1 month to 2 years, accounting for
