目的:探讨分叉病变对ST段抬高型急性心肌梗死(STEM I)患者急诊冠脉介入治疗(PC I)效果的影响。方法:318例连续入选的STEM I患者在发病12 h内行PC I,根据冠脉造影提示是否为分叉病变分为分叉组(n=92)和非分叉组(n=226)。结果:分叉组PC I的成功率为86%,与非分叉组(84%)相比无显著差异。两组30 d主要不良事件也无统计学差异(分叉组与非分叉组:6%vs.7%)。结论:STEM I患者急诊PC I治疗分叉病变的即刻和近期疗效与无分叉病变相近。
Objective: To investigate the effect of bifurcation on the efficacy of emergency PCI (PCI) in patients with ST-elevation acute myocardial infarction (STEMI). Methods: Thirty-eight consecutive STEM I patients underwent PCI within 12 hours of onset and were divided into bifurcation group (n = 92) and non-bifurcated group (n = 226) according to coronary angiography. Results: The success rate of PC I in the forked group was 86%, which was not significantly different from that in the non-forked group (84%). There were also no significant differences in the 30-day adverse events between the two groups (bifurcated vs non-forked: 6% vs. 7%). Conclusions: The immediate and immediate effects of emergency PC I in patients with STEM I on bifurcation are similar to those without bifurcation.
