ABSTRACT
Objective To investigate the diagnostic value of blood homocysteine,ankle -brachial index and brachial -ankle pulse wave velocity in elderly patients with coronary heart disease (CHD).Methods 97 patients with routine coronary angiography were classified into CHD group (65 cases)and non -CHD group (32 cases) according to the results of coronary angiography.There were 24 cases with single -vessel disease in 65 CHD cases, 21 cases with double -vessel disease and 20 patients with multivessel disease of CHD.Basic clinical parameters,age, gender,TC,TG,LDL -C,HDL -C,etc and blood HCY,ABI,baPWV levels were compared among groups.Results The age of double -vessel disease group,multivessel disease group was significantly higher than that in single -vessel disease group(t =3.721,3.927,all P 0.05),and the ABI of multi -vessel disease,double vessel disease group were significantly lower than that of non -CHD group (all P <0.01).HCY,baPWV of CHD group were significantly higher than non -CHD group(all P <0.01 ),double vessel disease,HCY multivessel disease group,ABI,baPWV average water with single -vessel disease group were signifi-cantly different(all P <0.01 ).With the increase of coronary lesions involved,the blood HCY,baPWV showed an increasing trend and ABI showed an decreasing trend.Conclusion Combined detection of HCY,baPWV and ABI has great value in early detection and early intervention of CHD in the elderly.
