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。
PURPOSE: To evaluate the effect of pre-AMI angina attack on the prognosis of acute myocardial infarction (AMI). Methods: The infarct size, recent complications and in-hospital mortality of 183 AMI patients with angina pectoris in the previous week before infarction and 136 AMI patients without angina pectoris before infarction were compared. Results: The area of infarction in patients with angina pectoris was smaller (P <0.05). The incidences of cardiovascular events and hospitalizations such as severe cardiac arrhythmia, acute pulmonary edema and cardiogenic shock in one week after infarction were lower than those without angina pectoris Attack group (P <0.05). Conclusion: Pre-infarction angina pectoris has obvious myocardial protective effect on myocardial ischemic preconditioning.
