ABSTRACT
BACKGROUND:
The long-term prognostic significance of in-hospital worsening renal function (WRF) during treatment of acute cardiac decompensation (ACD) remains controversial.METHODS:
We analyzed data from 100 patients (mean age=75 years; 53% men) presenting with ACD, in whom the serum cystatin C (Cys-C) concentration was measured upon admission to the hospital and 4 days later. We examined the relationship between changes in Cys-C and primary study endpoint of risk of death and re-hospitalization for management of ACD, up to 180 days, searched for predictors by multiple variable analysis and calculated the hazard ratios (HR) and 95% confidence intervals (CI).RESULTS:
A median (25th to 75th percentile) increase in Cys-C from 1.29 (0.88-1.66)mg/l on day 1 to 1.31 (1.00-1.84)mg/l on day 4, observed in 66% of all patients, was associated with a significant decrease (p=0.040) in the 180-day incidence of primary study endpoint. By multiple variable regression analysis, an increase in Cys-C was an independent predictor of death and re-hospitalization for management of ACD (HR 0.415; 95% CI 0.193-0.885; p=0.023).CONCLUSIONS:
An increase in serum Cys-C concentration after hospitalization for management of ACD was associated with a decreased, long-term incidence of primary study endpoint.Key words
