Predictive value of hematological parameters in prognosis of congestive heart failure patients in a tertiary hospital, Addis Ababa, Ethiopia

Hematocrit (Hct), red cell distribution width (RDW), and absolute lymphocyte count (ALC) varied significantly across NYHA functional classes, indicating prognostic relevance in chronic heart failure. Among these, RDW and ALC demonstrated stronger discriminatory performance. Together, these readily available parameters may serve as practical adjuncts for risk stratification in CHF, particularly in resource-limited settings.
