急性心肌梗死患者中MACE和非MACE心电图特征及意义

Characteristics and Significance of Electrocardiogram in MACE and non-MACE of Acute Myocardial Infarction

目的探讨急性心肌梗死患者心电图特征及意义。方法选取2017年1月-2018年1月在南京医科大学附属淮安第一医院治疗的急性心肌梗死患者132例,根据住院期间是否发生主要不良心血管事件(MACE)进行分组,比较临床资料、心电图差异。结果132例患者住院期间中发生MACE患者为27例(MACE组),未发生MACE患者105例(无MACE组);MACE组和无MACE组患者性别、年龄、糖尿病、高血压和吸烟比例比较差异无统计学意义(P>0.05);MACE组左心室射血分数(LVEF)为(50.02±9.22)%,明显低于无MACE组(Pv0.05),而 Gensini 评分为(34.48± 10.21)分,明显高于无 MACE 组(P<0.05);MACE 组 QTc 间期为(460.50±54.48)ms,明显高于无MACE组(P<0.05);MACE组T波倒置、ST段压低比例分别为55.56%和40.74%,明显高于无MACE组(P<0.05)。结论在急性心肌梗死患者中,发生MACE和未发生MACE者心电图特征有一定差异,值得进一步研究。

Objective To explore the characteristics and significance of electrocardiogram in patients with acute myocardial infarction. Methods 132 patients with acute myocardial infarction treated in our hospital from January 2017 to January 2018 were divided into groups according to whether major adverse cardiovascular events (MACE) occurred during hospitalization, the differences of clinical data and electrocardiogram were compared. Results Among 132 patients, 27 (MACE group) had MACE during hospitalization, and 105 (no MACE group) had no MACE;There were no significant difference in sex, age, diabetes, hypertension and smoking rate between MACE group and non-MACE group(P< 0.05);The left ventricular ejection fraction (LVEF) in MACE group (50.02±9.22)% was significantly lower than that in non-MACE group (P<0.05) while Gensini score (34.48± 10.21) was significantly higher than that in non-MACE group (P<0.05);The QTc interval in the MACE group was (460.50±54.48) ms, which was significantly higher than that in the non-MACE group (P<0.05);The proportion of T-wave inversion and ST-segment depression in MACE group were 55.56% and 40.74%, which were significantly higher than those in non-MACE group (P<0.05). Conclusion In patients with acute myocardial infarction, there are some differences in ECG characteristics between those with and without MACE, which deserves further study.
