摘要
作者用心尖搏动图(ACG)评定了冠脉造影病人100例的左心室舒张功能,并与正常对照组比较。结果表明,随冠脉狭窄程度的加重和狭窄支数的增多,病人的ACG各指标如:快速充盈时间(RFT)、A波振幅相对比(A/H)、A波与全舒张期高度比(A/D)、总舒张时间指数(TARTI)及舒张振幅时间指数(DATI)均有显著或非常显著改变,且DATI与冠脉狭窄程度呈良好负相关(Y=-0.75DATI+0.98)。提示ACG对临床无创评估冠脉狭窄程度有重要参考价值。
The left ventricular diastolic function of 100 patients with coronary stenosis was assessed by apex-cardiogram,and the results were compared with that of 40 normal subjects.Rapid filling time was decreased only in severe stenosis group (P<0.01).Significant changes in A/H,A/D,DATI,TARTI were also foword in mild,moderate severe stenosis groups.With progressive coronary artery stenosis,DATI showed a negative correlation with the change in percent stenosis.The change in DAT vs % stenosis was expressed in the following equation:Y=0.75DATI+0.98 (where Y=% stenosis of coronary artery).
