糖尿病时冠状动脉病的发病率增加,青年糖尿病人的动脉硬化提前,以及动脉硬化与临床前糖尿病合并存在问题,已是众所周知的事实。但近年来在临床上和流行病学上发现,在没有冠状动脉主支病变和高血压的情况下,糖尿病会发生心脏功能不全,称之为糖尿病性心肌病,表现特点为:多系中年或老年患者,糖尿病史至少三年,有明显的心脏大和全心衰竭,临床类似于特发性充血性心肌病。心电图有心室肥厚或非特异性ST—T的变化。早期病人处于临床前期无明显症状,心脏收缩时间间期测定(简称STI测定)可作为左室功能受
It is a well-known fact that the incidence of coronary artery disease increases in diabetes, the advancement of atherosclerosis in young people with diabetes and the combination of atherosclerosis and preclinical diabetes mellitus. However, in recent years, clinically and epidemiologically found that in the absence of major coronary artery disease and hypertension, cardiac dysfunction occurs in diabetes, known as diabetic cardiomyopathy, characterized by: multi-line middle-aged Or elderly patients, at least three years of history of diabetes, significant heart and heart failure, clinical similar to idiopathic congestive cardiomyopathy. ECG changes in ventricular hypertrophy or non-specific ST-T. Early patients in the preclinical no obvious symptoms, systolic time interval measurement (referred to as STI determination) can be used as left ventricular function
