高龄冠心病患者外周动脉硬化与冠状动脉硬化的研究

Peripheral arterial atherosclerosis and coronary atherosclerosis in elderly patients with coronary heart disease

目的观察高龄冠心病患者颈动脉、股动脉、股浅动脉、腘动脉的内-中膜厚度(IMT)与冠状动脉硬化的相关性。方法选经冠状动脉造影确诊为冠心病的高龄患者86例,选冠状动脉造影证实无冠状动脉狭窄的患者20例为对照组,采用二维超声检测颈、股、股浅、腘动脉的IMT。动脉粥样硬化斑块积分采用Sutton法,并与冠状动脉病变程度进行对比分析。结果高龄老年冠心病患者外周动脉的IMT,斑块积分显著高于对照组(P<0.001)。斑块指数与冠状动脉病变程度呈正相关。结论颈、股、股浅、腘动脉粥样硬化与冠状动脉粥样硬化的病变相平行。

Objective To study the correlation of intima media thickness （IMT）of carotid, femoral, superficial femoral, and popliteal arteries, with coronary atherosclerosis. Methods Two - dimensional echocardiography was used to measure the IMT and plaques of carotid, femoral, superficial femoral, and popliteal arteries in 86 elderly patients with coronary heart disease confirmed by coronary angiography, plaque scores were calculated using Sutton＇ s method to quantify the extent of atheroasclerosis in carotid, femoral, superficial femoral, and popliteal arteries. The carotid, femoral, superficial semoral, popliteal artery atherosclerosis and coronary atherosclerosis in coronary artery disease were analyzed and compared. And 20 healthy subjects examined by coronary angiography Served as control group. Results The IMT and plaque scores of carotid, femoral, superficial femoral, and popliteal arteries were significantly increased in coronary artery disease group than in control group. Conclusions Carotid, femoral, superficial femoral, and popliteal artery atheroasclerosis and coronary atheroasclerosis are parallel.
