摘要
目的 :评价急性心肌梗塞 (AMI)前心绞痛发作对 AMI预后的影响。方法 :对梗塞前一周内心绞痛发作的 AMI 183例与梗塞前无心绞痛发作的 AMI 136例的梗塞面积 ,近期并发症及住院病死率进行比较分析。结果 :有心绞痛发作组梗塞面积较小 (P<0 .0 5 ) ,梗塞后一周内严重心律失常 ,急性肺水肿 ,心源性休克等心血管事件及住院病死率均低于梗塞前无心绞痛发作组 (P<0 .0 5 )。结论 :梗塞前心绞痛发作对心肌产生的缺血预适应有明确的心肌保护作用。
Objective:To evaluate the effect of angina pectoris attack before infarction on the prognosis of acute myocardial infarction(AMI).Methods:The 183 cases of AMI with angina attack within a week before infarction and the 136 cases of AMI without angina attack were compared with each other and analyzed in terms of the infarct size,complication in short term and hospita lization mortality.Results:The infarct size of the group with angina attack is significantly smaller than that of the group without angina attack ( P <0 05).The angiocardiopathy such as severe arrhythmia,acute pulmonary edema and cardiac shock,etc.Within a week after infarction and the hospitalization mortality of the group with angina attack were all significantly lower than that of the group without angina attack( P <0 05).Conclusion:The angina attack before infarction can produce the ischemic preconditioning on myocardium that provides myocardium with definite protection.
