Abstract

Aim. Red cell distribution width (RDW) is a measure of anisocytosis. Higher values are robustly associated to adverse outcome in several conditions, including chronic heart failure (HF). The present study aimed to compared its prognostic role with that of echocardiographic parameters in this kind of patients. Methods. 232 stable and optimally treated chronic HF patients were enrolled. We excluded subjects suffering from valvular diseases or atrial fibrillation. They underwent blood sampling and echocardiographic examination. The primary endpoint of the study was cardiovascular death and/or HF hospitalization in the first year after enrolment. Results. 49 patients reached the primary endpoint. RDW best cut-off at ROC curve was 14.45%. Univariate analysis associated mitral regurgitation grade, left ventricular ejection fraction (LVEF), posterior wall thickness (PWT), LV mass index, and RDW>14.45% to the primary endpoint. Multivariate regression analysis showed that LVEF, PWT, and RDW>14.45% predict the primary endpoint. Area under ROC curve was 0.808 for LVEF, 0.762 for NYHA class, and 0.761 for RDW. Conclusion. In chronic HF patients RDW is a better predictor of adverse outcome than several echocardiographic parameters associated to outcome itself (LV mass index, mitral regurgitation grade), predicts prognosis even adjusting for those parameters, age and NYHA class, and is associated to several echocardiographic measurements. In conclusion, RDW can expand our tool bag in order to better follow-up these patients.
