Relationship between hematocrit and coronary artery lesions in elderly coronary heart disease patients
Abstract：Objective To study the relationship between hematocrit and coronary artery lesions in elderly coronary heart disease (CHD) patients.Methods Five hundred and ninety-eight elderly patients were divided into CHD group (n=422) and CHD-free group (n=176) according to their coronary angiography.Their general clinical data,routine blood test parameters and biochemical test parameters were compared.The SYNTAX score of coronary artery lesions was recorded.Results The age was significantly older,the ratio of males and smoking was significantly higher,the incidence of DM and the ESR were significantly higher,the number of WBC,neutrophils and monocytes was significantly greater,the serum levels of FBG,TG,LDL-C and apolipoprotein A were significantly higher whereas the number of RBC was significantly smaller,the serum hemoglobin and LDL-C levels and hematocrit were significantly lower in CHD group than in CHD-free group (P＜0.05,P＜0.01).Spearman rank correlation analysis showed that the hematocrit was negatively related with the SYNTAX score (r=-0.151,P=0.000).The area under the ROC curve for hematocrit in predicting CHD was 0.589 (95％CI:0.540-0.639,P=0.001).The cut-off point value of hematocrit was 39.95％ with a sensitivity of 61.1％ and a specificity of 46.6％.Conclusion Hematocrit is closely related with coronary artery lesions in elderly CHD patients,and lower hematocrit can predict the risk of CHD.
