用γ心功能仪测定21例冠心病人的九项心功能指标,并与18例正常人作对照,结果表明静态时冠心病者LVEF值(51.2±7)明显低于正常人(59.1±8),两者差异有非常显著性意义(P<0.01);而运动后正常人LVEF明显提高(P<0.01),冠心病者明显下降(P<0.01)。因此,γ心功能仪对冠心病人左心功能评定是一种非损伤性的好方法。
Nineteen cardiac function indexes of 21 patients with coronary heart disease were measured by γ-cardiac function instrument and compared with 18 healthy people. The results showed that the LVEF value of static coronary artery disease patients (51.2 ± 7) was significantly lower than that of normal subjects (59.1 ± 8) ), There was a significant difference between the two groups (P <0.01). After exercise, LVEF in normal subjects was significantly increased (P <0.01) and coronary heart disease was significantly decreased (P <0.01). Therefore, γ cardiac function in patients with coronary heart disease left ventricular function assessment is a good non-invasive method.
