摘要
目的:探讨既往心绞痛对急性心肌梗死急诊介入治疗成功后患者预后的影响。方法:将162例首次急性心机梗死患者,根据既往有无心绞痛史分为A组(有心绞痛史76例)和B组(无心绞痛史86例)。所有患者在发病后6h内均接受经皮冠状动脉腔内成形术(PTCA)及支架术,比较两组心衰、心源性休克、严重心律失常及死亡率等的差异。结果:心衰发生率A组低于B组(11.0%Vs20.9%);心源性休克发生率A组低于B组(3.95%Vs17.4%),严重心律失常发生率A组低于B组(10.8%Vs23.3%),死亡发生率A组低于B组(3%Vs10.5%,P<0.001),CK-MB峰值平均数A组比B组低(P<0.05)。结论:既往心绞痛发作可减少心肌梗死范围,严重并发症及近期死亡发生率低。
Objective To explore the effect between previous angina pectoris and short - term prognosis in patients with acute myocardial infarction. Methods： A total of 162 consecutive patients with a first acute myocardial infarction were divided into two groups according to the present or absence of previous angina , every patients was done PCI in 6 hours, and the differences in heart failure, Cardionenic shock , severe arrhythmia and morality. Results： Compared with control group , patients with previous angina had lower rate of heart failure, cardionenic shock, severe arrhythrnia, morality and peak of creatine kinase. Conclusion： Patients with a first acute myocardial infarction, those with previous angina pectoris would reduce severe complications and mortality rate.
