【摘要】 目的:探讨ST段抬高型急性下壁心肌梗死(AIMI)并心力衰竭(HF)患者的冠状动脉病变特点及临床特征。方法:对108例行急诊冠状动脉介入治疗的ST段抬高型AIMI患者的临床资料进行分析,根据心功能分为2组,HF组32例,无HF组76例,比较2组临床特征及冠脉病变特点。结果:HF组年龄偏大(P<0.05),血清肌酐水平、恶性心律失常、心源性休克需要主动脉内球囊反搏比例(均P<0.01),三度房室传导阻滞发生率显著高于非HF组(P<0.05);罪犯血管为右冠状动脉,合并前降支血管病变,HF组显著高于非HF组(P<0.05和P<0.01)。结论:ST段抬高型AIMI罪犯血管为右冠状动脉,同时合并有前降支血管病变时,易发生心力衰竭。更多还原

【Abstract】 Objective:To explore the characteristics of coronary artery lesions and clinical features of patients with ST segment elevation acute inferior wall myocardial infarction (AIMI) complicated with heart failure (HF).Methods:Clinical data of 108 patients with ST-segment elevation AIMI undergoing emergency percutaneous coronary intervention were analyzed.Patients were divided into two groups according to the heart function:32 cases with HF and 76 cases without HF.The clinical features and coronary artery characteristics were compared between two groups.Results:The results revealed that patients in HF group were more likely to be old age(P<0.05),and had a higher serum creatinine level(P<0.01),lower left ventricular ejection fraction (P<0.01),and higher incidence of third degree atrioventricular block (P<0.05)when compared with those patients without HF;the frequency of right coronary artery lesion together with left anterior descending-vessel disease was notably higher in HF group than those without HF(P<0.05,P<0.01). Conclusions:Patients with right coronary artery involvement together with left anterior descending-vessel disease were prone to develop HF in case of ST-segment elevation AIMI.更多还原
