Does obesity increase the risk of new-onset atrial fibrillation after cardiac surgery?
Obesity is a significant risk factor for postoperative atrial fibrillation and should be incorporated into future risk models.
Obesity is an important determinant of new-onset AF after cardiac surgery. Future postoperative AF risk models should incorporate BMI or obesity levels. Studies examining the efficacy of AF-minimizing prophylactic interventions in high-BMI patients, particularly in the elderly, may be warranted.
Zacharias et al. (Tue,) studied this question.
