Key Points

The study aims to evaluate the effectiveness of the red blood cell distribution width–albumin ratio as a predictor of outcomes in heart failure patients.
Conducted a 6-year cohort study on heart failure patients
Measured red blood cell distribution width and albumin levels
Analyzed the association between RAR levels and patient prognosis
Elevated RAR levels correlated with higher risk of heart failure rehospitalization
Higher RAR levels were linked to increased all-cause mortality
RAR demonstrated potential for risk stratification in heart failure management

Abstract

Elevated RAR levels are independently associated with a worse prognosis in HF patients, including higher risks of HF re-hospitalization and all-cause mortality. The RAR holds promise as a valuable tool for risk stratification and prognosis assessment in HF management.
