本文用心尖搏动图评定96例冠脉不同程度狭窄冠心病人的左室舒张功能,并与正常对照组比较。冠脉狭窄病人的RFT、a/A比值、a/D比值、TARTI、DATI的均值均有显著或非常显著改变。DATI与冠脉狭窄程度有良好的相关性,为无创伤性方法判定冠脉狭窄程度提供了依据。
In this paper, 96 patients with coronary artery stenosis coronary heart disease in patients with varying degrees of left ventricular diastolic function, and compared with the normal control group. Coronary artery stenosis patients RFT, a / A ratio, a / D ratio, TARTI, DATI mean significant or very significant change. DATI has a good correlation with the degree of coronary stenosis and provides a basis for determining the degree of coronary artery stenosis by noninvasive methods.
