【摘要】 目的　评价急性下壁心肌梗死及其高危合并症的临床意义。方法　总结 2 14例住院急性心肌梗死患者 ,其中下壁心肌梗死 10 4例 ,全部病例在病史、心电图改变及心肌酶谱均符合急性心肌梗死的诊断标准。单纯下壁梗死6 4例 ,下壁及正后壁梗死 2 1例 ,下壁及右心室梗死 6例 ,下壁右心室及正后壁梗死 4例 ,前壁加下壁梗死 4例 ,下壁及高侧壁梗死 5例。结果　主要合并症有高度房室传导阻滞18例 ,前壁缺血 2 3例 ,右心室梗死出现低血压状态 5例。下壁心肌梗死出现高危合并症者住院病死率为 17% ,而无合并症的住院病死率是 8 6 %。结论　下壁心肌梗死出现上述三大并发症提示梗死面积较大 ,病死率高 ,预后差。更多还原

【Abstract】 Objectives This study examined whether patients of inferior wall acute myocardial infarction (AMI) with high risk subsets were at higher risk for in-hospital mortality and assessed the determinants of high mortality. Methods The charts of patients ( n=104 ) with inferior wall AMI and an initial electrocardiogram that displayed precordial ST-segment depression ( n=23 ), right ventricular AMI with hypotension ( n=5 ) or advanced or complete atrioventricular block ( n=18 ) were reviewed. Results and Conclusions High risk subsets of inferior wall AMI are at high risk for in-hospital mortality, but the determinants of in-hospital mortality of inferior wall AMI may not necessarily coincide with those responsible for high risk subsets, probably because of larger area in high risk subsets of inferior wall AMI.更多还原
