由冠心病所致的心肌病综合征,远比伴有慢性心力衰竭的其他冠心病临床综合征(如室壁瘤、二尖瓣关闭不全、室间隔破损、暂时性反复性缺血)为多见。而且,其他的综合征因有胸痛史、心脏杂音、或心电图上心肌梗塞的证据,当其发生时几乎总可引起怀疑。相反,至少某些由冠心病引起的心肌病病例,并不伴有冠心病的临床线索。本文报道对临床上难以解释的心力衰竭病人,通过前瞻性临床病理分析,观察由冠心病引起的心肌病的发病率。方法:20岁以上慢性心力衰竭死亡病例,凡有典型心绞痛史、心肌梗塞史、或心电图有透壁心肌梗塞图型者诊断为冠心病,瓣膜性心脏病和先天性心脏病由临床和导管检查诊断,导管检查证实冠状动脉正常且无重要瓣膜病变者,诊断为心肌病(与冠心
Cardiomyopathy syndrome due to coronary heart disease is much more than other clinical syndromes of coronary heart disease (such as aneurysm, mitral regurgitation, ventricular septal damage, temporary recurrent ischemia) with chronic heart failure see. Moreover, other syndromes are almost always suspect when they occur because of history of chest pain, heart murmurs, or evidence of myocardial infarction on an electrocardiogram. In contrast, at least some of the cases of cardiomyopathy caused by coronary heart disease are not associated with clinical clues to coronary heart disease. This article reports the clinically difficult to explain the patients with heart failure, by prospective clinical and pathological analysis of coronary heart disease to observe the incidence of cardiomyopathy. Methods: The deaths of patients with chronic heart failure over the age of 20 were diagnosed as coronary heart disease, valvular heart disease and congenital heart disease by clinical and catheterization tests with history of typical angina pectoris, history of myocardial infarction, or electrocardiogram with transmural myocardial infarction Diagnosis, catheterization confirmed normal coronary artery valve disease and no significant diagnosis of cardiomyopathy (and coronary heart
