摘要
目的探讨急性ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)患者ST段抬高指数(∑STI)与其左心室功能的相关性。方法选择72例初发急性STEMI接受急诊直接冠状动脉介入治疗(PCI)的患者,根据直接PCI术后∑STI回落的情况分为ST段回落组和非ST段回落组。观察两组患者年龄、性别、吸烟史、前壁心肌梗死、高脂血症病史、高血压病史、心绞痛病史、CK-MB、2型糖尿病病史、发病至就诊时间、Killip分级、住院期间及直接PCI术后6个月左室射血分数(LVEF)。结果两组患者年龄、性别、梗死部位、心绞痛病史、CK-MB、Killip分级等比较,差异均无统计学意义(P>0.05);而ST段回落组患者住院期间LVEF及直接PCI术后6个月LVEF均明显高于非ST段回落组,差异有统计学意义(P<0.05)。结论∑STI对急性STEMI患者的左心室功能有较好的预测价值。
Objective To investigate the relationship between ST-segment elevation index （ ∑ STI） and left ventricular function for acute ST-segment elevation myocardial infarction（STEMI） patients. Methods According to the circumstance of ∑ STI fall after percutaneous coronary inter- vention（PCI） , 72 acute STEMI patients who had undergone emergency treatment of PCI directly were divided into ST-segment fall group and non-ST-segment fall group. The following items were observed in the two groups, including age, sex, history of smoking, anterior myocardial infarction, history of hyperlipidemia, history of hypertension, history of angina peetoris, CK-MB , history of type 2 diabetes, onset ＆ visiting time, Killip classification, and left ventricular ejection fraction （LVEF） in hospital and 6 months after direct PCI. Results No statistically significant difference in age, sex, infarct sites, history of angina pectoris, CK-MB, Killip classification, etc. was existed between the two groups （ P 〉 0.05 ）. However, LVEF of ST-segment fall group in hospital and 6 months after direct PCI were significantly higher than that of non-ST-segment fall group, with statis- tically significant difference（ P 〈 0.05 ）. Conclusion ∑ STI has great clinical value in predicting left ventricular function of acute ST-segment elevation myocardial infarction patients .
