Association between hemoglobin-to-red cell distribution width ratio and 30-day mortality after cardiac surgery.

ABSTRACT:

Background

Postoperative mortality after cardiac surgery remains a significant challenge, with traditional risk scores showing limited predictive accuracy. The hemoglobin-to-red cell distribution width ratio (HRR) has emerged as a novel biomarker with potential prognostic value. This study aims to evaluate the association between preoperative HRR, red cell distribution width (RDW), and 30-day postoperative mortality in cardiac surgery patients. We hypothesized that preoperative HRR and RDW are associated with 30-day postoperative mortality in cardiac surgery patients.

Methods

We conducted a retrospective study of 926 patients who underwent cardiac and aortic surgeries. Data on demographics, comorbidities, and perioperative details were extracted from electronic health record
