摘要
目的利用高频超声评价冠心病(CAD)患者肱动脉内皮依赖性舒张功能(EDD)及其临床意义。方法对113例连续冠脉造影(CAG)受检者术前行高频超声检查肱动脉EDD,并对两种检查结果进行相关性分析。结果冠脉狭窄组、急性心肌梗死(AMI)组肱动脉EDD明显低于对照组(P<0.01);AMI组EDD显著低于心肌缺血组(P <0.01)。结论CAD患者的EDD明显降低。
Objective To investigate the endothelium-dependent dilation of brachial artery in patients with coronary artery diseases(CAD) .Methods Analysis of EDD was conducted in 113 patients before consecutive coronary arteriography(CAG)was applied, and the correlation between the examinations was analyzed. Results EDD of brachial artery induced by reactive hyperemia in patients with single and multiple coronary vessel stenosis and with acute myocardial infarction was lower than that of the control group( P 〈 0.01) ,and that in patients with coronary vessel stenosis was lower than that in patients with acute myocardial infarction( P 〈 0.01 ). Conclusion EDD lesions really exist in patient with CAD.
