目的探讨颈动脉粥样硬化与冠心病的相关性。方法 2011年05月至2012年05月期间,我院诊治的80例拟诊冠心病患者,给予颈动脉彩色超声检测,对颈动脉后壁内中膜厚度(IMT),进行测量,根据测量结果计算斑块积分,以及斑块发生率,并在1周内进行冠状动脉造影术。根据造影结果,将其分为对照组和冠心病组,分别为50例和30例。结果与对照组相比(0.73±0.21),冠心病组IMT明显增高(0.96±0.77),P<0.05;与对照组相比(1.13±0.83),冠心病组斑块积分明显增高(2.11±1.25),P<0.05;与对照组相比(16.7%),冠心病组斑块发生率明显升高(60.0%),P<0.05。对于冠心病组,颈动脉斑块超声检查的诊断敏感性为86.0%。结论冠心病与颈动脉粥样硬化有明显的相关性,通过颈动脉彩色多普勒超声检查,可以了解是否存在,或者冠心病的病变程度,相应地进行预防性治疗,或者及时的对症治疗。
Objective To investigate the relationship between carotid atherosclerosis and coronary heart disease. Methods From May 2011 to May 2012, 80 patients diagnosed as coronary heart disease in our hospital were given carotid color ultrasound to measure the IMT of the carotid artery. According to the measurement results Plaque scores were calculated as well as plaque incidence and coronary angiography was performed within 1 week. According to angiography results, it was divided into control group and coronary heart disease group, 50 cases and 30 cases. Results Compared with the control group (0.73 ± 0.21), IMT was significantly increased in CHD group (0.96 ± 0.77, P <0.05). Compared with the control group (1.13 ± 0.83), the score of plaque in CHD group was significantly higher (2.11 ± 1.25), P <0.05; Compared with the control group (16.7%), the incidence of plaque in coronary heart disease group was significantly increased (60.0%), P <0.05. For coronary heart disease group, the diagnostic sensitivity of carotid plaque ultrasonography was 86.0%. Conclusion Coronary heart disease and carotid atherosclerosis have obvious correlation. Carotid color Doppler ultrasound examination can understand the existence of coronary heart disease or the degree of lesion, accordingly, prophylactic treatment or timely symptomatic treatment.
