Comparison of Risk of Atrial Fibrillation among Black versus White Patients Following Coronary Artery Bypass Grafting

Obesity has been identified as a risk factor for postoperative atrial fibrillation (POAF) following coronary artery bypass grafting (CABG). However, no studies have addressed the influence of race on this association. A total of 13,594 patients undergoing first-time, isolated CABG without preoperati...

Description
Summary:Obesity has been identified as a risk factor for postoperative atrial fibrillation (POAF) following coronary artery bypass grafting (CABG). However, no studies have addressed the influence of race on this association. A total of 13,594 patients undergoing first-time, isolated CABG without preoperative atrial fibrillation between 1992 and 2011 were included in our study. The association between body mass index (BMI) and POAF was compared by race. Relative risk and 95% confidence intervals were computed using maximum likelihood log-binomial regression. Increasing levels of BMI were associated with higher POAF risk following CABG among black but not white patients (P interaction =0.0009).
