颈动脉及股动脉粥样硬化预测冠心病

目的利用体表超声研究颈动脉及股动脉粥样硬化与冠状动脉粥样硬化的关系。方法根据冠状动脉造影,将61名患者分为冠心病组(35人)及正常组(26人),利用高频线阵探头测定颈动脉及股动脉后壁内中膜厚度(IMT),观察有无斑块形成及其程度。结果冠心病组患者颈动脉及股动脉内中膜厚度较正常组明显增厚,斑块的阳性率高,两者呈高度相关(P<0.05)。并且随着血管病变的增加,冠心病程度加重。结论颈动脉及股动脉粥样硬化是冠心病的高危因素,对冠心病有较大的预测价值。

Coronary atherosclerosis prediction based on carotid and femoral atherosclerosis

Objective To evaluate the relation between carotid and femoral atherosclerosis and coronary artery diseases (CAD) with ultrasonography. Methods Thirty-five CAD patients and 26 normal controls according to coronary angiography were examined with high frequency ultrasound. The intimia-media thickness(IMT)and plaques were measured. Results The IMT of carotid and femoral arteries in CAD patients was significantly increased in comparison to that in normal group.The dectation rate of arterial plaques was significantly high in CAD patients compared to that in normal group. The severity of arterial diseases corrected well with the extent of CAD. Conclution Carotid and femoral atherosclerosis are risk factors of CAD and have great values in predicting CAD.
