Evaluating three biomarkers as prognostic factors of in-hospital mortality and severity in heart failure: A prospective cohort.

Objective: To identify the relationship between red blood cell distribution width (RDW, %), interleukin-6 (IL-6) (pg/ml), high sensitivity-c-reactive protein (hs-CRP) (mg/l), in-hospital mortality and disease severity among patients with heart failure (HF).

Methods: Prospective cohort. We included adults diagnosed with acute non-ischemic HF in 2015.
