目的分析非ST段抬高型心肌梗死(NSTEMI)患者冠状动脉病变特点。方法选取2008-01-01—2016-02-29南京医科大学附属无锡第二医院收治的NSTEMI患者136例及ST段抬高型心肌梗死(STEMI)患者207例。比较NSTEMI与STEMI患者冠状动脉病变特点。结果 NSTEMI患者左前降支(LAD)病变发生率低于STEMI患者,左回旋支(LCX)、左冠状动脉主干(LM)发生率及侧支循环形成者所占比例、多支病变者所占比例高于STEMI患者(P<0.05)。130例NSTEMI患者中,单支病变者49例(占37.6%),双支病变者35例(占26.9%),三支病变者46例(占35.5%);完全闭塞者30例(占23.0%),90%≤狭窄率<100%者93例(占71.5%),50%≤狭窄率<90%者7例(占5.5%)。结论 NSTEMI患者以LCX、LM病变及多支病变为主。
Objective To analyze the characteristics of coronary lesions in patients with non-ST elevation myocardial infarction (NSTEMI). Methods Totally 136 NSTEMI patients and 207 ST - segment elevation myocardial infarction (STEMI) patients admitted to Wuxi Second Hospital Affiliated to Nanjing Medical University were recruited from January 2008 to January 2016. Compare the characteristics of coronary lesions in patients with NSTEMI and STEMI. Results The incidence of left anterior descending artery (LAD) in patients with NSTEMI was lower than that in patients with STEMI. The incidence of left circumflex coronary artery (LCX) and left main coronary artery (LM) and the proportion of collateral circulation, the proportion of multivessel disease Higher than STEMI patients (P <0.05). In 130 patients with NSTEMI, 49 patients (37.6%) had single vessel disease, 35 patients (26.9%) had double vessel disease, 46 patients (35.5%) had three lesions, and 30 patients (23.0% Ninety-nine (71.5%) had a stenosis rate of <100%, and seven (5.5%) had a stenosis rate of <90%. Conclusion The patients with NSTEMI are mainly LCX, LM and multi-vessel disease.
