【摘要】 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经皮冠状动脉介入治疗(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%比57.2%，P=0.043)。两组间住院死亡率无差异，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亦无显著性(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。
