心踝血管指数在老年冠心病中的应用价值研究

Application Value of Cardio-ankle Vascular Index to the Elderly with Coronary Heart Disease

目的探讨心踝血管指数(CAVI)在老年冠心病中的应用价值。方法将557例老年冠心病患者(冠心病组)及131例体检正常者(对照组)进行CAVI检测、病史采集及常规生化指标检查,分析CAVI与老年冠心病的关系。结果冠心病组CAVI高于对照组,差异有统计学意义(P<0.01)。CAVI与冠心病严重程度呈正相关(r=0.694,P=0.003);Logisitic回归分析结果显示:年龄、吸烟史、高血压、糖尿病、低密度脂蛋白胆固醇、CAVI是冠心病严重程度的危险因素(P<0.05)。结论 CAVI与冠心病严重程度关系密切,CAVI检查有助于预测冠心病严重程度,且其操作简便,无创伤性,临床上尤其基层医院值得推广应用。

Objective To explore the application value of cardio-ankle vascular index（CAVI） to the elderly with coronary heart disease.Methods 557 cases of old patients with coronary artery disease（CHD group） and 131 cases of healthy control group received medical CAVI detection,medical history collection and conventional biochemical examination to analyze the relationship between CAVI and coronary heart disease with ages.Results CAVI in coronary heart disease group was higher than that in the control group,the difference was statistically significant（P0.01）.CAVI was positively correlated to the severity of heart disease（r=0.694,P=0.003）;Logisitic regression analysis showed that ages,smoking,high blood pressure,diabetes,low density lipoprotein cholesterol,and CAVI were the risk factors for the severity of coronary diseases（P0.05）.Conclusion CAVI was closely related to the severity of coronary heart disease.CAVI inspection could help to predict the severity of coronary heart disease and was worth popularizing in basic-level hospitals with simple operation and without traumatic damages.
