【摘要】 目的:探讨初发急性心肌梗死(AMI)患者梗塞前72 h内心绞痛对AMI预后产生的影响。方法:选择166例初发AMI患者进行分析,根据AMI前72 h内有无典型心绞痛发作分为:梗塞前心绞痛组(76例):即AMI前72 h有典型心绞痛发作;对照组(90例):即AMI前72 h无心绞痛发作。结果:与对照组比较,梗塞前心绞痛组肌酸磷酸激酶(CPK)峰值更低,多部位梗塞明显减少,且心衰、心源性休克及近期死亡的发生率明显降低(P<0.05,P<0.01)。结论:AMI前72 h的心绞痛发作可减少梗塞范围、严重并发症及近期死亡率。更多还原

【Abstract】 Objective: To explore the effect of angina pectoris in 72 hours before the initial of acute myocardial infarct( AMI)on the clinical feathers and near prognosis of AMI. Methods: Data of 166 initial AMI patients in our hospital during 1997.4 -2002,8 were analyzed. Those patients were divided into two groups; MI group(76 patients), in which typical angina pectoris came on in 70 hours before AMI, and control group(90 patients), in which there was no typical angina pectoris before AMI. Re-sults: Compared with control group, patients in MI group had lower peak of creatine kinase, and lower rates of heart failure, multi-focal infarction, cardionenic shock, and near death ( P < 0. 05 or P < 0.01). Conclusion: The angina pectoris in 72 hours before AMI presage that severe complications would reduce and the rate of near deaths after AMI would decrease.更多还原
