急性心肌梗死后近期病情稳定患者的冠状动脉造影特点

Features of coronary angiograms of stable patients with recent acute myocardial infarction

目的通过回顾性分析患者的冠状动脉造影特点,探讨是否应对急性心肌梗死后近期病情稳定的患者常规行冠状动脉造影。方法回顾性分析50例首次急性心肌梗死发病后病情稳定的患者,在1周至2个月行冠状动脉造影的结果,并与61例病情不稳定的患者对照。结果病情稳定患者冠状动脉造影检出≥70%冠状动脉狭窄性病变的比率为90%,病情不稳定患者的检出率为93.4%。差异无显著性(P=0.755)。结论急性心肌梗死后近期病情稳定的患者,大多数冠状动脉有严重狭窄,应考虑常规行冠状动脉造影检查。

Objective To investigate whether or not stable patients with recent acute myocardial infarction should receive a routine coronary angiogrophy by retrospective analysis of their coronary angiograms. Methods All of the patients underwent coronary angiogrophy from one week to 2 months after the onset of acute myocardial infarction. The features of coronary angiograms of 50 stable patients with first acute myocardial infarction were compared with that of 61 unstable patients＇, Results The lesion of ≥70% coronary stenosis was found in 90% of stable patients and in 93.4% of unstable patients. The difference was not statistically significant（ P = 0. 755）. Conclusion Most of stable patients with first recent acute coronary infarction have severe coronary stenosis. Routine coronary angiography in these patients should be considered.
