| 摘 要： | 回顾性分析急诊24 h 行经皮冠状动脉介入(PCI)治疗的急性心肌梗死(AMI)患者149例,其中112例梗死相关血管(IRA)为右冠状动脉(RCA 组)与37例 IRA 为左回旋支动脉(LCX 组),结果显示 LCX 组与 RCA 组比较,LCX 组发病至就诊时间较长,心力衰竭及胸闷发生率较高( P <0．05),但其右室心肌梗死、房室传导阻滞发生率较低(P <0．05),心电图定位准确性及敏感性均较低(P <0．05),LCX组较 RCA 组非 ST 抬高急性心肌梗死发生率较高( P <0．05),冠状动脉造影 LCX 组右侧优势型较少(P <0．05),且IRA 位于 LCX 以近段病变为主。

| Abstract: | A total of 149 acute myocardial infarction patients undergoing primary PCI in the first 24 hours were an-alysed, including 112 RCA-infarct-related artery(RCA group) and 37 LCX-infarct-related artery(LCX group) AMI patients. Compaerd with RCA-related MI, patients with LCX-related MI had less ratios of right ventricular myocar-dial infarction,atrioventricular block(P < 0. 05),but longer onset to admission time,higher rates of heart failure as well as chest dirtress(P < 0. 05). The accuracy and sensitivity of electrocardiogram on LCX-related MI positioning was lower(P < 0. 05), LCX-related NSTEMI incidence was higher(P < 0. 05), and less cases of right dominance in coronary angiography occurred in LCX group(P < 0. 05). Furthermore,proximal LCX occlusion was more fre-quently presented. |
