左室射血分数对急诊冠状动脉介入治疗急性ST段抬高心肌梗死患者远期预后的影响

目的 探究在急性ST段抬高心肌梗死行急诊冠状动脉介入治疗患者中左室射血分数对远期预后的影响度.方法 截取我院2007年3月至2012年1月共300例患者,按左室射血分数(LVEF)分为低值组(LVEF≤40％)、中间组(40％＜LVEF＜60％)、高值组(60％＜LVEF),对比三组患者间临床资料差异性.结果 三组患者中MACE情况比较 总发生率比较:低值组高于中间组(P＜0.05);低值组高于高值组(P＜0.01);中间组高于高值组(P＜0.05).三组间MACE发生率由高到低为低值组、中间组、高值组,差异有显著性(P＜0.05).结论 在行急诊PCI治疗的STEMI患者随访过程中MACE发生率伴随LVEF减低而升高,随访中需加大对LVEF较低患者的宣教力度,减少MACE发生率,提高PCI术后满意度.

The effect of left ventricular ejection fraction to long-term prognosis of emergent percutaneous coronary intervention in patients with acute ST segment elevation myocardial infarction

Objective To explore the effect of left ventricular ejection fraction to long-term prognosis in patients with acute ST segment elevation myocardial infarction in emergency percutaneous coronary interventional therapy. Methods In our hospital from March 2007 to January 2012, 300 patients, according to left ventricular ejection fraction （LVEF） were divided into lower values in the group （LVEF 〈40%）, intermediate group （40%〈LVEF〈60%）, higher values in the group （60%〈LVEF）, clinical data difference were analyzed and compared in 3 groups. Results In the group of high values, at the time of admission, higher blood pressure appeared oxygen good advantage, MACE total incidence was compared： low value contrast intermediate group： c2=4.66, （ p〈0.05 ）; low value vs high value group：c2=18.53, （ ,0〈 0.01 ）; the middle group contrast group： c2=high value in 5.10, （ P〈0.05 ）.In three groups of MACE from high to low value group, intermediate group, high value group, difference line statistical analysis indicated that P was less than 0.05.Conclusion In the treatment of patients with emergency PCI STEMI during follow-up of the incidence of MACE increased with LVEF decreasing, thus, during the follow-up the low LVEF patients should get more education strength, in order to decrease the incidence of MACE, and improve PCI postoperative satisfaction.
