桡动脉增强指数与冠心病严重程度的相关性研究

Relationship between Radial Arterial Augmentation Index and Severity of Coronary Artery Disease

目的探讨桡动脉增强指数(AIR)在评价冠心病发生中的敏感性,研究AIR与冠心病严重程度的相关性。方法 128例患者被冠脉造影结果分为4组,1支病变组、2支病变组、3支病变组及非狭窄组,脉搏波检测装置计算受检者AIR。结果各病变组AIR值均高于非冠脉狭窄组,差异有统计学意(P<0.05),AIR值随冠脉狭窄的程度增大而增加。AIR与相关因素的相关性的相关因素对比显示,冠脉病变、吸烟、Cre等与AIR正相关,P<0.01。结论 AIR是预测冠心病严重程度的重要危险指标。

Objective To investigate whether radial arterial augmentation index（AIR） was an independent risk factor of coronary heart disease,and the relationship between AIR and the severity of coronary artery disease.Methods 128 subjects were divided into 4 groups by the result of coronary angiography： 1 lesion group;2 lesions group;3 lesions group and normal control group.AIR was measured using the Omron HEM-9010AI.Results The larger the AIR was,the more the number of coronary stenosis vessels was.Linear regression analysis indicated that AIR was significantly correlated with the severity of coronary stenosis（correlation coefficient）.Multilinear regression analysis indicates,severity was the independent risk factor for coronary heart disease,it correlated positively with the severity of heart disease（P0.01）.Conclusion AIR is an independent risk factor of coronary heart disease and a predictor of angiographic coronary artery disease severity.
