目的分析伴梗塞前心绞痛的急性心肌梗死(AMI)患者的临床及造影特点,并评价梗塞前心绞痛对直接PCI近期疗效的影响。方法连续观察247例行直接PCI的AMI患者,根据AMI前2周内有无心绞痛分为梗塞前心绞痛组和非梗塞前心绞痛组,分析其临床和造影特点,并评价其对直接PCI近期疗效的影响。结果梗塞前心绞痛组共107例(43·3%)。与非梗塞前心绞痛组比较,梗塞前心绞痛组年龄较大(分别为62·3岁和60·8岁),左室射血分数较高(60·8%:57·2%,P=0·043)。两组间住院死亡率差异无统计学意义,住院期间死亡、再梗塞、急诊CABG、心源性休克、术后室颤需电复律的联合终点事件差异无统计学意义(P>0·05)。结论梗塞前心绞痛对AMI直接PCI近期疗效无保护作用。
Objective To analyze the clinical and angiographic features of patients with acute myocardial infarction (AMI) with pre-infarction angina and evaluate the effect of pre-infarction angina on the immediate effect of direct PCI. Methods A total of 247 AMI patients undergoing direct PCI were enrolled in this study. According to the presence or absence of angina in the first 2 weeks of AMI, they were divided into pre-infarction angina group and non-infarcted angina group. The clinical and radiographic features were analyzed. influences. Results A total of 107 patients (43.3%) had pre-infarction angina pectoris. Compared with non-infarction patients, pre-infarction angina patients were older (62.3 years and 60.8 years respectively), higher left ventricular ejection fraction (60.8% vs 57.2%, P = 0 · 043). There was no significant difference in in-hospital mortality between the two groups. There was no significant difference in the combined end-point events of death, re-infarction, emergency CABG, cardiogenic shock and postoperative ventricular fibrillation during hospitalization (P> 0.05) ). Conclusion Preinfarction angina has no protective effect on immediate PCI of AMI.
