摘要
目的探讨影响急诊PCI术后心电图ST段变化的意义及影响因素。方法根据急诊PCI术后心电图与术前对比,对应导联ST段回落≥50%为ST段回落组(212例),ST段回落<50%为ST段无回落组(42例),比较两组一般临床资料及院内发生的恶性心血管事件,并分析影响ST段回落的因素。结果无回落组年龄、2型糖尿病、前壁心梗及术前心功能Killip≥II级的比例,发病至再通时间与ST段回落组比较有统计学差异,P<0.05;术后院内发生的恶性心血管事件也明显增加。结论急诊PCI术后ST段回落是心肌再灌注和判断早期预后的有效指标,2型糖尿病、前壁心梗,术前心功能Killip≥II级、发病至再通时间是影响术后ST段回落的独立预测因素。
Objective To elucidate the clinical implication of the early ST segment changes in acute ST-segment elevation myocardial infarction（STEMI） after emergent percutaneous coronary intervention（PCI） and its influential factors.Methods Two groups were divided-declining more than 50% as ST segment decline group（n=212,∑STE resolved≥50%） and less than 50% as none-ST segment decline group（n=42,∑STE resolved 50%）,to compare the nomal clinical data and the major adverse cardiac events（MACE）,and to observe the influence of the ST segment descending.Results In none-ST segment decline group,the patients were often older or had diabetes and experienced longer to open the infarct related arteries（IRA）（P 0.05）.The rates of the anterior wall of myocardial infarction and the cardiac function with Killip≥ II level were both higher in the patient s of none-ST segment decline group than that in group ST segment decline group.The incidence of major in hospital adverse cardiac events（MACE） was also significantly higher after angioplasty in none-ST segment decline group than that in group ST segment decline group（P 0.05）.Conclusion The early decline degree of ST segment may be an effective parameter to represent improved myocardial perfusion and estimate the clinical outcome in STEMI patients.Diabetes,the anterior wall of myocardial infarction,the cardiac function with Killip≥II level and the opening time of IRA are the independent risk factors affecting the decline degree of ST segment.
