目的探讨超声检查在诊断冠心病患者动脉血管功能异常中的临床应用价值。方法收集冠心病患者50例,作为实验组,收集健康人员50名,作为对照组,分别测定两组人员的肱动脉内皮依赖性血管舒张功能以及颈动脉硬化参数,分析压力应变弹性系数、硬化度、顺应性与肱动脉内皮依赖性血管舒张功能的相关性。结果实验组患者的肱动脉内皮依赖性血管舒张功能系数、顺应性明显低于健康人员;实验组患者的压力应变弹性系数、硬化度明显高于健康人员;经检验,压力应变弹性系数、硬化度与肱动脉内皮依赖性血管舒张功能呈负相关;顺应性与肱动脉内皮依赖性血管舒张功能呈正相关。结论超声检查在冠心患者动脉血管功能异常的判断中具有良好的临床应用价值。
Objective To investigate the clinical value of ultrasonography in the diagnosis of arterial dysfunction in patients with coronary heart disease. Methods Fifty patients with coronary heart disease were collected. Fifty healthy subjects were collected as the experimental group. The brachial artery endothelium-dependent vasodilatation and carotid artery atherosclerosis were measured as the control group. The stress-strain elastic modulus, , Compliance and brachial artery endothelium-dependent vasodilation related. Results The endothelium-dependent vasodilatory function and compliance of the brachial artery in the experimental group were significantly lower than those in the healthy group. The stress-strain elastic coefficient and the degree of sclerosis in the experimental group were significantly higher than those in the healthy group. The stress-strain elastic modulus, And brachial artery endothelium-dependent vasodilation was negatively correlated; compliance and brachial artery endothelium-dependent vasodilation was positively correlated. Conclusion Ultrasonography has a good clinical value in judging arterial vascular dysfunction in patients with coronary heart disease.
