用γ心功能仪平衡法测定22例冠心病的左心室功能。结果:18例劳累性心绞痛病人静息时的左心室射血分数(LVEF)为58.68±9.84,与对照组比较差异无显著性意义,(P>0.05);运动时冠心病组LVEF值为47.81±11.51,明显低于对照组(P<0.01);4例陈旧性心肌梗塞病人静息时LVEF值(41±7.53明显低于正常人(P<0.01)。认为,γ心功能仪测定左心室功能对冠心病的诊断有重要价值,但对早期冠心病的诊断应加做运动试验,才能获得准确信息。
Measurement of left ventricular function in 22 patients with coronary heart disease by γ balance method. Results: The left ventricular ejection fraction (LVEF) at resting time was 58.68 ± 9.84 in 18 patients with exertional angina pectoris. There was no significant difference between the control group and the control group (P> 0.05). The LVEF of exercise group was 47.81 ± 11.51, significantly lower than that of the control group (P <0.01). The LVEF values at rest in 4 elderly patients with AMI (41 ± 7.53, P <0.01) were significantly lower than those in the control group Function of coronary heart disease diagnosis has important value, but the diagnosis of early coronary heart disease should be added to do exercise test, in order to obtain accurate information.
