作者选择符合下列3项者为缺血性心肌病:(1)左心室摄影下心搏出率在0.4以下,且按AHA分类可见各部位的异常收缩。(2)经冠状动脉造影证实,主要冠状动脉分枝75%以上有明显狭窄。(3)既往无原发性心瓣膜病及先天性心脏病史。共25例,其中内科治疗组16例,以强心、利尿及血管扩张药物治疗为主。外科治疗组9例,均进行A-C搭桥术。平均冠状动脉患病枝数:前者2.2枝,后者3.4枝。平均心脏功能:前者2.9度,后者3.2度。两组既往有无心肌梗塞史,听诊有无奔马律,超声心动图检查二尖瓣前叶是否出现B-B’段,并测定左室舒张末期直径(LVDd),心导管检查肺动脉收缩压(PAS),心脏系数(CI),左心室摄影计算心搏出率
The authors selected those who meet the following three were ischemic cardiomyopathy: (1) left ventricular cardioplegia rate of 0.4 or less, and by the AHA classification showed abnormal contraction of various parts. (2) confirmed by coronary angiography, the main coronary artery branches more than 75% obvious stenosis. (3) past no history of primary valvular heart disease and congenital heart disease. A total of 25 cases, of which 16 cases of medical treatment group, with cardiac, diuretic and vasodilator drug-based. Surgical treatment group, 9 cases were performed A-C bypass surgery. The average number of coronary artery disease branches: the former 2.2, the latter 3.4. Average heart function: the former 2.9 degrees, the latter 3.2 degrees. The two groups had no history of myocardial infarction, auscultation with or without anesthesia, echocardiography check whether the anterior mitral valve appeared B-B ’segment, and measured left ventricular end-diastolic diameter (LVDd), cardiac catheterization pulmonary artery systolic pressure (PAS), cardiac coefficient (CI), left ventricular imaging stroke rate
