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 investigate the correlation between intima - media thickness (IMT) and coronary atherosclerosis in carotid artery, femoral artery, superficial femoral artery and popliteal artery in elderly patients with coronary heart disease. Methods Totally 86 elderly patients diagnosed as CHD by coronary angiography were selected. Twenty patients without coronary stenosis who underwent coronary angiography were selected as the control group. The IMT of cervical, femoral, superficial and popliteal arteries were detected by two-dimensional ultrasonography. Atherosclerotic plaque score using Sutton method, and coronary artery lesions were compared. Results The IMT and plaque scores of peripheral artery in elderly patients with coronary heart disease were significantly higher than those in control group (P <0.001). Plaque index and the degree of coronary artery disease was positively correlated. Conclusions Neck, femoral, superficial femoral neck and 腘 Atherosclerosis are parallel with coronary atherosclerosis.
