目的 :通过分析梗塞前心绞痛对急性心肌梗塞愈后的影响 ,探讨缺血预适应对心肌梗塞预后的价值。方法 :将45例急性心肌梗塞患者分为梗塞前心绞痛组(A)和无梗塞前心绞痛组(B) ,就其冠心病危险因子 ,严重合并症 ,病死率及心肌酶峰值进行对照分析。结果 :A组严重心律失常 ,心力衰竭发生率 ,心肌酶峰值及住院病死率均较B组低。结论 :梗塞前心绞痛作为缺血预适应指标对预测心肌梗塞病情及预后有重要价值
OBJECTIVE: To investigate the prognostic value of ischemic preconditioning on myocardial infarction by analyzing the effect of pre-infarction angina on the prognosis of acute myocardial infarction. Methods: Forty-five patients with acute myocardial infarction were divided into pre-infarction angina group (A) and non-infarcted pre-angina group (B), and their coronary heart disease risk factors, serious complications, mortality and myocardial enzyme peak were compared. Results: A group of serious arrhythmia, heart failure, myocardial enzyme peak and in-hospital mortality were lower than the B group. Conclusion: Pre-infarction angina pectoris as an indicator of ischemic preconditioning has important value in predicting myocardial infarction status and prognosis
