Abstract: Objective Discuss elderly hypertension of chronic heart failure among the edema of lower limbs and the N end of b-type natriuretic peptide(NT-proBNP) formerly relationship and its value in differential diagnosis.Methods Hospitalized for high blood pressure and breathing difficulties in 301 cases of elderly patients,with 220ng/L for the NT-proBNP exception standard defines value,and comparing the edema of lower limbs and the NT-proBNP levels and heart failure.Results In the elderly hypertension of chronic heart failure population of double lower limbs swelling predict heart failure with NT-proBNP similar value.Conclusion Elevated levels of double lower limbs swelling in the NT-proBNP positive predictive value was 90.3％,negative predictive value was 42.1％,sensitivity 74.4％,specificity 80.0％ ;On heart failure of sensitivity 86.4％,specificity 78％.The edema of lower limbs were significantly associated with NT-proBNP and heart failure.
