Impact of prognostic nutritional index on mortality among patients receiving coronary artery bypass grafting surgery: a retrospective cohort study.

ABSTRACT:

Background

The Prognostic Nutritional Index (PNI), calculated from serum albumin levels and lymphocyte counts, is a simple and objective measure of nutritional status. While PNI has been shown to be a significant prognostic tool in gastrointestinal surgery and heart failure, its role in patients undergoing coronary artery bypass grafting (CABG) remains unclear. This study aims to evaluate whether PNI can serve as a meaningful risk factor for patients undergoing CABG.

Methods

This observational retrospective analysis involved a substantial sample of 2889 patients who underwent isolated CABG at one of four medical centres. The primary outcomes included short- and long-term mortality. Perioperative serum albumin levels and total lymphocyte counts used to calculate PNIs were col
