目的比较ST段抬高型急性心肌梗死(STEMI)与非ST段抬高型急性心肌梗死(NSTE-MI)临床及冠状动脉病变的特点。方法回顾STEMI与NSTEMI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情况。结果STEMI组完全闭塞率为46.5%,三支病变率为32.6%,有Ⅱ级以上侧支循环的为39.5%,NSTEMI组的三支病变率为56.3%、≥75%的严重狭窄率为59.30%,完全闭塞率11.00%,有Ⅱ级以上侧支循环的为65.6%。STEMI的CK和TNI峰值(2346±1072)IU/L与(1.67±0.69)ng/ml,高于NSTEMI(835±476)IU/L与(0.83±0.49ng/ml),两组间高血压、糖尿病患病率差异无统计学意义。结论STEMI完全闭塞率高于NSTEMI,冠状动脉病变程度NSTEMI高于STEMI,二者具有不同的冠状动脉病变特点。
Objective To compare the clinical characteristics of coronary artery disease (STEMI) and non-ST-elevation acute myocardial infarction (NSTE-MI). Methods The clinical data and coronary angiography data of STEMI and NSTEMI patients were retrospectively analyzed. The clinical features and coronary artery lesions were analyzed. Results The complete occlusion rate was 46.5% in the STEMI group, 32.6% in the three-vessel disease group, 39.5% in the collateral vessels with grade Ⅱ or higher, 56.3% in the NSTEMI group, and 59.30 in ≥ 75% %, The complete occlusion rate was 11.00%, there were 65.6% of the collateral circulation above the grade Ⅱ. The peak values of CK and TNI in STEMI were 2346 ± 1072 IU / L and 1.67 ± 0.69 ng / ml, higher than that of NSTEMI 835 ± 476 IU / L and 0.83 ± 0.49 ng / ml, respectively There was no significant difference in the prevalence of diabetes. Conclusion The rate of complete occlusion of STEMI is higher than that of NSTEMI, the severity of coronary artery disease is higher than that of STEMI, and both of them have different characteristics of coronary artery disease.
