Therapeutic effect of erythropoietin combined adjuvant iron treatment on patients with diastolic heart failure complicated anemia / 心血管康复医学杂志

ABSTRACT

Objective:To observe the influence of erythropoietin (EPO)combined adjuvant iron treatment on cardiac function,exercise capacity and anemia in patients with diastolic heart failure (DHF)complicated anemia.Methods:A total of 94 DHF + anemia patients were randomly divided into routine treatment group (n=46)and combined treatment group (n=48,received EPO combined adjuvant iron treatment based on routine treatment).Patients re-ceived 6min walking test,levels of hemoglobin (Hb)and N-terminal pro brain natriuretic peptide (NT-proBNP), transmitral early diastolic peak velocity deceleration time (DT),early diastolic peak flow velocity (E),late diastolic peak flow velocity (A)and E/A etc.were measured and compared between two groups before and after six-month treatment.Results:Compared with before treatment,after treatment,NT-proBNP and DT significantly reduced, E/A and 6min walking distance significantly rose in both groups,P <0.05 or <0.01;compared with routine treat-ment group after treatment,there were significant reductions in NT-proBNP level [(368.4±110.7)pg/ml vs.(239 ±89.7)pg/ml]and DT [(257.5±73.4)ms vs.(208.9±59.1)ms],and significant rise in Hb level [(83.3±9.2) g/L vs.(122.1±13.6)g/L],E/A [(0.87±0.3)vs.(1.07±0.27)]and 6min walking distance [(367.54±21.08) m vs.(438.63±20.35)m]in combined treatment group,P <0.05 all.Conclusion:Erythropoietin combined iron treatment can better improve heart function and exercise capacity in patients with diastolic heart failure complicated anemia.
