Evaluation of HRR (Hemoglobin/Red Blood Cell Distribution Width Ratio) and RAR (Red Blood Cell Distribution Width/Albumin Ratio) in Myocarditis Patients: Associations with Various Clinical Parameters.

Aim: This study investigates the prognostic value of the Hemoglobin/Red Blood Cell Distribution Width Ratio (HRR) and the Red Blood Cell Distribution Width/Albumin Ratio (RAR) in patients with myocarditis. We aimed to evaluate how these novel biomarkers correlate with clinical parameters, disease severity, and outcomes.

Methods: A retrospective analysis was conducted on 301 patients diagnosed with myocarditis between January 2020 and March 2024.
