摘要
目的观察ST段抬高型心肌梗死(STEMI)梗死相关动脉合并心肌桥对直接行经皮冠状动脉介入(PCI)治疗的影响。方法将594例STEMI直接行PCI治疗成功的患者分为两组:梗死相关动脉合并心肌桥者46例为肌桥组,梗死相关动脉未合并心肌桥者548例为对照组,比较两组直接行PCI治疗术后即刻冠状动脉造影结果和6个月主要心脏不良事件(死亡、靶血管重建、靶病变重建、非致死性心肌梗死)。结果594例患者术后即刻前向血流TIMI3级率为92.1%(547/594),其中肌桥组为60.9%(28/46),对照组为94.7%(519/548),两组比较差异有统计学意义(P〈0.01)。住院病死率为4.4%(26/594),其中肌桥组为13.0%(6/46),对照组为3.6%(20/548),两组比较差异有统计学意义(P〈0.01)。6个月主要心脏不良事件发生率肌桥组为22.5%(9/40),对照组为5.1%(27/528),两组比较差异有统计学意义(P〈0.01)。结论梗死相关动脉合并心肌桥患者直接PCI治疗术后即刻前向血流改善较差,可能是导致住院病死率高和6个月主要心脏不良事件常见的原因之一。
Objective To study the effect of ST- elevation myocardial infarction(STEMI) related artery combined with myocardial bridge on primary percutaneous coronary artery intervention (PCI) therapy. Methods Five hundred and ninety -four patients underwent primary PCI therapy from March 1999 to April 2006 were retrospectively studied. These patients were divided into two groups at random: infarct related artery with myocardial bridge( myocardial bridge group), infarct related artery without myocardial bridge (control group). The difference of prompt coronary angiography finding and 6 months main adverse cardiovascular event (MACE) rate between the two groups were investigated. Results Thrombolysis in myocardial infarction(TIMI) outflow Ⅲ rate was 92.1% (547/594) in patients promptly after PCI, it was 60.9% (28/46) in myocardial bridge group and 94.7% (519/548)in control group(P 〈 0.01 ). Inpatient mortality rate was 4.4% (26/594) in 594 patients underwent primary PCI, 13.0% (6/ 46) in myocardial bridge group and 3.6% ( 20/548 ) in control group ( P 〈 0. 01 ). Six months MACE rate was 22.5 % (9/40) in myocardial bridge group and 5.1% (27/528) in control group ( P 〈 0.01 ). Conclusion The artery grade outflow was poor in patients with infarct related artery with myocardial bridge, which may be related to high mortality rate and 6 months MACE rate in those patients.
