老年冠心病踝臂指数与血管病变的关系

Relationship of ankle brachial index and vasculopathy in elderly people with coronary artery disease

目的探讨老年冠心病踝臂指数与血管病变的关系。方法将47例老年冠心病患者依据双源冠脉CT结果，分为单支血管病变组17例、两支血管病变组12例、三支血管病变组18例，以19例非冠心病患者作为对照组，做踝臂指数检测．统计学比较各组患者的踝臂指数的高低。结果老年冠心病患者的踝臂指数明显低于非冠心病患者（P〈0．01）。在老年冠心病患者中，随着血管病变数目的增多，踝臂指数有下降趋势，三支血管病变组明显低于单支血管病变组和两支血管病变组（P〈0．05）。但单支血管病变组和两支血管病变组两者之间未见统计学差异（P〉0．05）。结论老年冠心病与血管病变的关系密切，提示低踝臂指数的老年冠心病患者血管病变愈严重。

Objective To explore the relationship of ankle brachial index （ABI） and vasculopathy in elderly people with coronary artery disease （CHD） . Method 47 elderly CHD patients were divided into 3 groups according to the dual source CT coronary angiography results, single-vessel disease group （ 17 cases）, double-vessel disease group （ 12 cases）, triple-vessel disease group （ 18 cases）. The control group was the non CHD group （ 19 cases）. The ABI was measured and compared at the same time. Results The ABI of the CHD patients was significantly lower than that of the non CHD patients, CHD group 〈 non CHD group （P〈0.01）. In the CHD patients, the more severe vasculopathy, the lower was the ABL The ABI of the triple-vessel disease group was lower than that of the single-vessel disease group or the double-vessel disease group （P〈0.05） . There was no significant difference in the ABI between the singlevessel disease group and the double-vessel disease group （P 〉 0.05 ）. Conclusion In elderly CHD patients, ABI correlated with the vasculopathy which suggested the vasculopathy was much more severe in the lower ABI CHD patients than that in the others.
