• 摘要：

• 目的    探讨急性ST段抬高型心肌梗死(STEMI)患者梗死相关血管(IRA)与入门至球囊扩张（D-to-B）时间的关系。方法    连续入选2016年5—10月在首都医科大学附属北京安贞医院诊断为STEMI，症状发作12 h内接受冠状动脉造影且资料完整的患者179例。记录患者性别、既往病史、D-to-B时间及IRA等资料。根据IRA位置将患者分为3组：左前降支组（74例）、左回旋支组（25例）、右冠状动脉组（80例）。分析IRA与D-to-B时间的关系。结果    3组患者性别比例、危险因素、既往病史比较差异均无统计学意义（均P＞0.05）。左回旋支组D-to-B时间明显长于左前降支组和右冠状动脉组［（86±18）min比（74±16）、（67±12）min］（P＜0.05）。结论    IRA为左回旋支与D-to-B时间延长明显相关。

• Objective    To analyze the relation between infarct-related artery（IRA） and door-to-balloon(D-to-B) time in patients with acute ST-segment elevation myocardial infarction（STEMI）. Methods    A total of 179 STEMI patients were successively enrolled from May to October 2015 in Beijing Anzhen Hospital, Capital Medical University. All patients had coronary angiography in 12 h after the onset of infarction. General information, medical histories, D-to-B time and IRA were recorded. The patients were divided into 3 groups according to the location of IRA: left anterior descending artery(LAD) group（n＝74）, left circumflex artery(LCX) group（n＝25） and right coronary artery(RCA) group（n＝80）. The relation between IRA and D-to-B time was analyzed. Results   Sex ratio, risk factors and medical histories showed no significant differences among groups（P＞0.05）. D-to-B time in LCX group was significantly longer than that in LAD group and RCA group［（86±18）min vs （74±16）,（67±12）min］（P＜0.05）. Conclusion    The location of IRA is related to D-to-B time; LCX infarction is an independent predictor of longer D-to-B time.
