Abstract

Background The aim of the present study was to prospectively study whether a combination of markers for myocardial cell injury and left ventricular overload at admission can reliably risk stratify patients hospitalized for chronic heart failure (CHF). Methods and Results Serum concentrations of heart-type fatty acid binding protein (H-FABP) and plasma concentrations of brain natriuretic peptide (BNP) were measured at admission in 186 consecutive patients hospitalized for CHF. During a mean follow-up period of 534±350 days, there were 44 cardiac events, including 16 cardiac deaths and 28 readmissions for worsening heart failure. Normal upper limits for H-FABP and BNP values were determined from the receiver operating characteristic curves (4.3 ng/ml for H-FABP and 200 pg/ml for BNP). A stepwise Cox regression analysis demonstrated that high H-FABP (hazard ratio 5.416, p=0.0002) and high BNP (hazard ratio 2.411, p=0.0463) were independent predictors of cardiac events. High concentrations of both H-FABP and BNP at admission were associated with the highest incidence of cardiac mortality and cardiac events. Kaplan-Meier analysis also showed that the combination of H-FABP and BNP concentrations could reliably stratify patients for cardiac events. Conclusion Combined measurement of H-FABP and BNP concentrations at admission may be a highly reliable evaluation for risk stratifying patients hospitalized for CHF. (Circ J 2005; 69: 922 - 927)
