对１４４例煤矿工人主动脉、心脏和冠状动脉的尸检材料进行了分析，胸主动脉经苏丹Ⅳ染色后，用描图称重法分别计算出不同ＡＳ病变区百分比和ＡＳ病变指数。结果表明：煤工尘肺患者与无尘肺病组间ＡＳ病变指数的差异有显著性（Ｐ＜００５），煤矿工人胸主动脉粥样硬化明显重于同年龄组的非煤矿工人。通径分析显示，煤矿工人的ＡＳ病变与年龄有直接的联系，与接尘工龄和工种无关，但尘肺的严重程度对其有一定的促进作用。
The autopsy materials of the aorta, heart and coronary arteries of 144 coal miners were analyzed. The aorta of the thoracic aorta was stained with Sudan Ⅳ, and the percentage of AS lesions and the index of AS lesion were calculated by the method of micrograph. The results showed that there was a significant difference in AS index between coal miners pneumoconiosis and non-pneumoconiosis patients (P <005). Coal miners had significantly higher thoracic aortic atherosclerosis than non-coal miners in the same age group. Path analysis showed that the pathological changes of coal miners were directly related to their age and had no relation with the length of service and the type of work, but the severity of pneumoconiosis had a certain promotion effect on them.
