Objective:
To investigate the risk factors of worsening renal function (WRF) in patients with chronic heart failure (CHF) and WRF influence on prognosis.
Methods:
A case-control study were undertaken to analyze independent risk factor statistically related to incidence of WRF, and to assess the influence of WRF on prognosis.
Results:
The independent predictors of WRF were creatinine level at admission (OR 2.248, 95%CI 1.088 - 4.647, P = 0.029) and NYHA class on admission (OR 2.485, 95%CI 1.385 - 4.459, P = 0.002). The mortality of patient with WRF was obviously higher than that of control group during hospitalization (OR 3.824, 95%CI 2.452 - 5.637, P < 0.015).
Conclusions:
WRF is a common complication among patients hospitalized for CHF, and is obviously associated with mortality during hospitalization. Higher creatinine level and weak heart function are independent risk factors for incidence of WRF of patients with CHF.
