利用我科１９８０年以来１～７９岁尸检所得心脏１０７例，每１０岁为一年龄组，每组均为８例以上。经图像分析仪描记、电脑计算处理测得内膜、中膜面积、内弹性板周长及内膜面积占内弹性板等价圆面积的百分比。为心血管造影、血管超声波诊断冠状动脉粥样硬化提供可靠的数据。同时观察了不同年龄组冠状动脉各枝的狭窄程度。 107 cases of cardiac autopsies from 1 to 79 years old in our department since 1980 were used, and each 10-year-old group had more than 8 cases in each group. The image analyzer tracing, computer calculation of the measured endomembrane, medial membrane area, the inner elastic plate circumference and the inner membrane area of ​​the inner elastic plate equivalent circular area percentage. For cardiovascular angiography, vascular ultrasound diagnosis of coronary atherosclerosis provide reliable data. At the same time, we observed the degree of stenosis of coronary branches in different age groups.
