颈动脉超声测量在老年冠心病筛查的应用价值

Application value of carotid ultrasound measurement in screening senile coronary heart disease

目的探讨颈动脉超声测量在老年冠心病筛查的应用价值。方法依据冠状动脉造影结果将拟诊冠心病的老年患者80例分为冠心病组(50例)和非冠心病组(30例)。彩色多普勒超声检测两组颈动脉斑块及颈动脉内膜-中层厚度(IMT)。结果冠心病组颈动脉斑块检测率高于非冠心病组(84.0%vs.53.3%)(P<0.05)。冠心病组22例单支病变、24例双支病变和4例三支病变患者的IMT均大于非冠心病组[(0.85±0.07)mm、(1.10±0.08)mm和(1.34±0.07)mm vs.(0.75±0.24)mm](P<0.05)。结论超声测定颈动脉对于老年冠心病筛查有较好应用价值。

Objective To explore the application value of carotid ultrasound measurement in screening senile coronary heart disease （CHD ） .Methods According to the results of coronary arteriography ,80 senile patients with suspected diagnosis of CHD were divided into groups of CHD （50 cases） and non‐CHD（30 cases） .Carotid plaques and carotid intima‐media thickness（IMT） were detected by color Doppler ultrasound .Results The detection rate of carotid plaques in group CHD was higher than that in group non‐CHD（84.0% vs .53.3% ）（P〈0 .05） .The IMT of 22 cases with single‐vessel ,24 cases with double‐vessel lesions and 4 cases with triple‐vessel lesions in group CHD were all thicker than that in group non‐CHD [（0.85 ± 0.07） mm ,（1.10 ± 0.08） mm and （1.34 ± 0.07） mm vs .（0.75 ± 0.24） mm]（P〈0 .05） .Conclusion Carotid ultrasound measurement has good clinical value in screening senile patients with CHD .
