急性非ST段抬高型与ST段抬高型心肌梗死冠脉病变特征比较

目的比较非ST段抬高型急性心肌梗死（NSTEAMI）与ST段抬高型急性心肌梗死（STEAMI）冠状动脉病变的特点。方法回顾NSTEAMI与STEAMI患者的临床及冠状动脉造影资料,分析二者的临床特点及冠状动脉病变血管的支数、狭窄程度及侧支循环情况。结果 NSTEAMI组的多支病变率为63.34%,其中大于75%的严重狭窄率为78.33%,侧支循环率为30.00%,三者均高于STEAMI组,而完全闭塞率为8.33%,低于STEAMI组。两组间高血压、糖尿病患病率差异无统计学意义。在病变血管的构成上组间无差异。结论 NSTEAMI的冠状动脉病变程度高于STEAMI,完全闭塞率低于后者,二者具有不同的冠状动脉病变特点。

Comparative study of coronary artery lesion characteristics between non-ST-segment elevation acute myocardial infarction and ST-segment elevation acute myocardial infarction

Objective To Compare the characteristics of coronary artery lesions of non-ST-segment elevation acute myocardial infarction（NSTEAMI）and ST-segment elevation acute myocardial infarction（STEAMI）.Methods The Clinical and angiographic data of the NSTEAMI and STEAMI patients were reviewed.The clinical characteristics of both blood vessels and coronary lesion count,degree of stenosis and collateral circulation were analyzed.Results In NSTEAMI group,the rate of multi-vessel disease（71.00%）,severe stenosis（stenosis more than 75%,78.33%）,and collateral circulation（31.00%）were higher than those in STEAMI group,while the total occlusion rate was 8.33%,lower than that in STEAMI group.There was no significant difference in prevalence rates of hypertension and diabetes between the two groups.No difference in the composition of the involved blood vessels was found between the two groups.Conclusion NSTEAMI has a severer coronary artery disease but lower rate of complete occlusion than STEAMI.The characteristics of coronary artery disease were different in NSTEAMI and STEAMI.
