摘要: 目的:探讨冠状动脉(冠脉)急性完全闭塞的急性冠脉综合征(ACS)患者入院心电图的不典型改变,以便尽快做出侵入性治疗策略。方法:回顾性分析2014-01-2017-02于我院导管室行急诊PCI的1支主要冠脉急性完全闭塞患者168例,根据入院时心电图是否有典型改变分为2组:典型改变组156例(符合急性ST段抬高型心肌梗死典型心电图改变)和非典型改变组12例(表现为心电图无改变或ST段压低/T波倒置、低平)。了解3支主要冠脉闭塞的发生率、典型心电图改变发生率,不典型心电图改变发生率及其分布情况,记录患者进入急诊室大门到冠脉球囊扩张的时间(D-TO-B)和出院时左室射血分数(LVEF)。结果:168例患者冠脉闭塞性病变部位中,首先位于左前降支88例,其次为右冠脉58例,冠脉左回旋支22例;其中非典型改变组分别为5例(5.7%)、3例(5.2%)、4例(18.2%)。典型改变组D-TO-B时间为(2.75±0.76) h,非典型改变组为(3.54±0.80) h。左前降支闭塞患者中,非典型改变组较典型改变组EF值明显降低。结论:非典型改变组D-To-B时间明显延长,前降支闭塞非典型改变组心功能明显降低,所以早期识别有助于尽早采取侵入性治疗策略。Abstract: Objective:To investigate the atypical changes of electrocardiogram in patients with acute coronary syndrome (ACS) caused by acute complete occlusion of the coronary artery, and so we can make an invasive treatment strategy as soon as possible.Method:A total of 168 patients with ACS in our hospital from January 2014 to February 2017 were selected.Coronary angiography showed one of the coronary arteries completely closed.Patients' information was recorded and analysed, including symptoms, the incidence of three major coronary artery occlusion, the incidence of typical electrocardiogram changes, the incidence of atypical electrocardiogram changes and their distribution, the time of patient from the hospital door to the coronary artery balloon expansion time (door to balloon, D-TO-B) and EF values at discharge.Result:Of the 168 occlusive coronary arteries, 88 cases were left anterior descending artery, 58 cases were right coronary artery, and 22 cases were left circumflex artery, with 5 (5.7%), 3 (5.2%) and 4 (18.2%) cases in the atypical electrocardiogram group, respectively.The D-TOB time was (2.75±0.76) h in the electrocardiogram typical group and (3.54±0.80) h in the electrocardiogram atypical change group.In patients with left anterior descending coronary artery, compared with the electrocardiogram typical group, the EF value was significantly lower in the electrocardiogram atypical group. Conclusion:The D-To-B time was significantly prolonged and the cardiac function in patients with left anterior descending coronary artery occlusion was significantly decreased in the electrocardiogram atypical group.Therefore, early identification could help to adopt the invasive treatment strategy as soon as possible.
