Postoperative pneumonia in isolated coronary artery bypass grafting: A comprehensive study of epidemiology, etiology, and disease burden from China (2020-2023).

ABSTRACT:

Objective

To investigate the epidemiological trends,etiological profiles and disease burden metrics related to postoperative pneumonia following isolated coronary artery bypass grafting (CABG).

Methods

A retrospective analysis was conducted on data from 518 patients who developed postoperative pneumonia following isolated CABG between January 1, 2020, and November 30, 2023.

Results

Postoperative pneumonia occurred at a rate of 11.34% among the cohort (518/4569),which fluctuated by year (P < 0.001). Patients aged 60-80 and over 80 years exhibited significantly higher incidence rates compared to those under 60 years (all P < 0.05) A total of 416 strains were identified, with Gram-negative bacteria accounting for 86.5%, primarily represented by Klebsiella pneumoniae (31.
