ABSTRACT
Objective:To observe the clinical efficacy of rh-BNP combined with continuous renal replacement therapy on the re-fractory heart failure in cardiorenal syndrome. Methods:Totally 48 patients with refractory heart failure in cardiorenal syndrome in our hospital were selected and randomly divided into the observation group and the control group. The control group was received the con-ventional drug therapy combined with continuous renal replacement therapy, and the observation group was received rh-BNP therapy ad-ditionally. After 7 days, NT-ProBNP, heart rate, LVEF, SV, BUN, Scr and GFR of the two groups were compared, and the clinical efficacy of the two groups was evaluated. Results:After the treatment, all the observed indicators in the two groups were significantly improved than those before the treatment, and the improvement in the observation group was better than that in the control group ( P<0. 05). The total effective rate of the observation group was higher than that of the control group(91. 67% vs 79. 17%, P<0. 05). Conclusion:The combination of rh-BNP and continuous renal replacement therapy can improve heart and kidney function of the refrac-tory heart failure in cardiorenal syndrome with better efficacy.
