Heart failure (HF) is a major global public health problem associated with high morbidity, mortality, and healthcare expenditure. Red Cell Distribution Width (RDW), a routinely available hematological parameter reflecting erythrocyte size variability, has emerged as a potential prognostic biomarker in cardiovascular diseases. Elevated RDW has been linked with inflammation, oxidative stress, malnutrition, and poor cardiovascular outcomes.
