Perioperative atrial fibrillation and the long-term risk of ischemic stroke.

ABSTRACT:

Importance

Clinically apparent atrial fibrillation increases the risk of ischemic stroke. In contrast, perioperative atrial fibrillation may be viewed as a transient response to physiological stress, and the long-term risk of stroke after perioperative atrial fibrillation is unclear.

Objective

To examine the association between perioperative atrial fibrillation and the long-term risk of stroke.

Design, setting, and participants

Retrospective cohort study using administrative claims data on patients hospitalized for surgery (as defined by surgical diagnosis related group codes), and discharged alive and free of documented cerebrovascular disease or preexisting atrial fibrillation from nonfederal California acute care hospitals between 2007 and 2011. Patients undergoing
