近年来,对左心室舒张功能的研究愈来愈多,已证明在冠心病左心室舒张功能受损早于收缩功能受损,而且有人认为伴有左心室肥厚的疾病如冠心病、高血压病等发生心衰的90％为舒张障碍性心衰。本文利用心阻抗血流图观察AMI患者左心室主动舒张期的改变,旨在更深入地了解AMI对左室舒张功能的影响。 1 资料与方法 1.1 对象 (1)AMI组:20例,男15例,女5例,年龄43～66岁(平均53岁)。均有AMI典型症状、血清酶谱变化及心电图诊断依据。急性发作后2—3周。(2)心绞痛(CHD)组:按WHO标准选择冠心病劳累型心绞痛患者30例,男22例,女8例,年龄44～65岁(平均54岁)。均经病史、体检、心电图、超声心动图等项检查排除MI、心肌病及心瓣膜病等。(3)对照组:30例,男23例,女7例,年龄42～65岁(平均55岁)。经询问病史、体检,有关辅助检查排除心
In recent years, more and more studies on left ventricular diastolic function have been demonstrated in patients with impaired left ventricular diastolic function of coronary heart disease earlier than the impaired systolic function, and some people think that with left ventricular hypertrophy such as coronary heart disease, hypertension 90% of other heart failure occurs diastolic heart failure. In this paper, the change of left ventricular active diastolic phase in patients with AMI was observed by cardiac impedance and blood flow diagram to understand the effect of AMI on left ventricular diastolic function. 1 Materials and Methods 1.1 Object (1) AMI group: 20 cases, 15 males and 5 females, aged 43 to 66 years (mean 53 years). There are typical symptoms of AMI, changes in serum enzyme and ECG based on diagnosis. 2-3 weeks after acute attack. (2) Angina pectoris (CHD) group: Thirty patients with angina pectoris undergoing coronary heart disease were selected according to the WHO criteria. There were 22 males and 8 females, aged 44-65 years (average 54 years). Have been history, physical examination, electrocardiogram, echocardiography and other items excluded check MI, cardiomyopathy and valvular heart disease. (3) Control group: 30 cases, 23 males and 7 females, aged from 42 to 65 years (average 55 years). After asking medical history, physical examination, the auxiliary examination to exclude the heart
