Obesity is associated with postoperative outcomes in patients undergoing cardiac surgery: a cohort study

ABSTRACT:

Background

The purpose of present study was to determine whether obesity was associated with increased adverse outcomes after cardiac surgery.

Methods

This is a retrospective cohort study from a large international database called the Medical Information Mart for Intensive Care III (MIMIC-III). Patients who underwent cardiac surgery and greater than 18 years old were divided into either nonobese (BMI < 30 kg/m2) or obese (BMI ≥ 30 kg/m2). The primary outcome of this study was 28-day mortality from the date of operation. Secondary outcomes included ICU mortality, 1-year mortality, incidence of postoperative atrial fibrillation (POAF), hospital length of stay (HOS_LOS) and ventilation-free days within 28 days (VFD_28).
