心尖搏动图对陈旧性心肌梗塞患者左室舒张功能参数的对比分析

用心尖搏动图对52例陈旧性下壁心肌梗塞、47例陈旧性前间壁心肌梗塞、53例陈旧性广泛前壁心肌梗塞与50例正常对照组的左室舒张功能参数对比分析,结果显示:陈旧性心肌梗塞病人的TRTI、A/D比值、DATL、A/H、RFT、AST均值有显著或非常显著差异(P<0.05,P<0.01)。陈旧性心肌梗塞组间比较,广泛前壁心肌梗塞的A/D、SFT、AST均值有显著/或非常显著差异(P<0.05,P<0.01)。表明陈旧性心肌梗塞舒张功能异常及AST延长的代偿性改变。

EVALUATION OF APEXCARDIOGRAM ON LEFT VENTRICULAR DIASTOLIC FUNCTION IN PATIENTS WITH OLD MYOCARDIAL INFARCTION

The apexcardiographic parameters of left ventricular diastolic function in 152 patients with old myocardial infarction (MI), including 52 cases with old inferior MI, 47 cases with old anteroseptal MI, 53 cases with old extensive anterior MI, were analysed and compared with those of 50 healthy volunteers. The results show that TRTI, A/D ratio, DATI, A/H, RFT, AST in patients with old MI are all different significantly from those in healthy group (P <0.01), which suggests that diastolic disfunction in patients with old MI may be a compensatory process.
