摘　　要：目的 观察老年急性心肌梗死前有无心绞痛对心功能及预后的影响。方法 ７６例老年初发急性心肌梗死患者按急性心肌梗死发病前有无心绞痛发作分为两组，有心绞痛发作组４２例，无心绞痛发作组３４例，观察其心律失常、梗死后心绞痛、心功能和病死率。结果 心肌梗死前有心绞痛发作组的心原性休克和心力衰竭的发生率及病死率均低于心肌梗死前无心绞痛发作组（分别为３３．３％ vs５８．8％，２．４％ vs２３．５％），两组间差异有显著性，Ｐ＜０．０５；超声心动图检查发现ＬＶＥＦ和Ｅ／Ａ有心绞痛发作组高于无心绞痛发作组（分别为 ０．５２ ± ０．０５６ ｖｓ ０．４５±0.０３，０．８６±0.２９ vs ０．５４±0．３５），两组间差异有显著性，Ｐ＜0.05。结论 心肌梗死前有心绞痛对老年初发急性心肌梗死患者的心功能有保护作用，可改善患者的近期预后。Objective To observe the influence of pre-infarction angina on ventricular function and prognosis of first acute myocardial infarction in old people. Methods 76 first acute myocardial infarction old patients was divided into two groups: angina pectoris group (n = 42); no angina pectoris group (n = 34). Global left ventricular function was assessed by echocardiography, arrhythmia, cardiogenic shock, heart failure, infarction angina and mortality was observed in hospital. Results The rate of cardiogenic shock and heart failure and mortality was lower in angina pectoris group (33.3% vs 58.8%; 2.4% vs 23.5%), LVEF and E/A was higher in angina pectoris group (0.52 ± 0.056 vs 0.45 ± 0.03, 0.86 ± 0.29 vs 0.54 ± 0.35), P < 0.05. Conclusion pre-infarction angina possesses the protecting effects on ventricular function of first acute myocardial infarction in old people, and can improve the prognosis of first acute myocardial infarction in old people.
