【摘要】：目的探讨超声在老年冠心病患者颈动脉硬化及血流动力学检测中的价值。方法选取老年冠心病患者103例为实验组,根据冠状动脉造影结果将实验组分为单支病变组53例和非单支病变组50例,另选同期进行体检的无冠心病的老年患者103例为常规组。所有患者均接受超声检测,分析并比较颈动脉硬化情况和血流动力学参数。结果实验组内中膜厚度(IMT)增厚比例、存在斑块比例、IMT厚度、斑块厚度、Crouse积分均显著高于常规组,软斑比例显著高于常规组,扁平斑、硬斑比例显著低于常规组(均P0.05),两组混合斑比例无统计学差异(P0.05);实验组收缩期峰值流速(PSV)、阻力指数(RI)显著高于常规组(P0.05);单支病变组IMT增厚比例、颈动脉斑块比例均显著低于非单支病变组(P0.05)。结论应用超声可准确检测老年冠心病颈动脉硬化程度和血流动力学参数,为冠心病诊断和治疗提供有效依据。
[Abstract]:Objective to investigate the value of ultrasound in the detection of carotid atherosclerosis and hemodynamics in elderly patients with coronary heart disease. Methods 103 elderly patients with coronary heart disease were selected as experimental group. According to the results of coronary angiography, the experimental group was divided into single vessel lesion group (53 cases) and non-single vessel disease group (50 cases). 103 elderly patients without coronary heart disease were selected as routine group. All patients were examined by ultrasound. Results the intima media thickness (IMT) thickening ratio, plaque ratio (IMT) and plaque thickness (IMT) were analyzed and compared in the experimental group. The Crouse score was significantly higher than that of the routine group, the percentage of soft spot was significantly higher than that of the routine group, and the proportion of flat plaque and hard spot was significantly lower than that of the routine group (all P 0.05). There was no significant difference in the proportion of mixed spots between the two groups (P 0.05). The peak systolic velocity (PSV) and resistance index (RI) in the experimental group were significantly higher than those in the control group (P 0.05). The proportion of IMT thickening in single vessel lesion group. The ratio of carotid plaque was significantly lower than that of non-single vessel lesion group (P 0.05). Conclusion Ultrasound can accurately detect the degree of carotid atherosclerosis and hemodynamic parameters in elderly patients with coronary heart disease. To provide effective basis for the diagnosis and treatment of coronary heart disease.
