Long-Term Prognostic Value of the Prognostic Nutritional Index in Patients Undergoing Coronary Artery Bypass Grafting.

ABSTRACT:

Background

The Prognostic Nutritional Index (PNI) as an indicator of nutritional and immunological status has been widely applied in various medical conditions. However, its prognostic role in postoperative outcomes after coronary artery bypass grafting has not been fully elucidated. This study investigated the long-term prognostic impact of PNI for patients undergoing coronary artery bypass grafting.

Methods

A total of 6626 patients who underwent coronary artery bypass grafting from 2001 to 2017 were analyzed. PNI was calculated as 10×serum albumin (g/dL)+0.005×total lymphocyte count (per mm³).

Results

PNI is negatively correlated with age (r=-0.24, P<0.001) and positively correlated with body mass index (r=0.13, P<0.001). PNI w
