本文用选择性冠状动脉造影和无创心功检测方法,对照研究了100例造影病人心脏功能的改变与冠脉狭窄程度的关系。发现随冠脉狭窄程度的加重,心功能指标发生异常。收缩功能指标改变仅在中度狭窄以上有意义,而舒张功能指标改变在轻度狭窄病人即有意义,且舒张振幅时间指数DATI与冠脉狭窄程度呈良好相关性。分析A/D与PEP/LVET数值分布可见二者有交叉、重叠,且A/D较PEP/LVET相对敏感。
In this paper, selective coronary angiography and noninvasive heart function testing methods, a controlled study of 100 patients with contrast-enhanced cardiac function changes and the relationship between coronary stenosis. Found with the severity of coronary stenosis, abnormal cardiac function indicators. Changes in systolic function only meaningful in moderate stenosis, and diastolic function changes in patients with mild stenosis that is meaningful, and diastolic amplitude time index DATI and coronary stenosis showed a good correlation. Analysis of A / D and PEP / LVET numerical distribution shows that there is a cross, overlap, and A / D is relatively sensitive to PEP / LVET.
