Supports extended outpatient monitoring after cardiac surgery; leaves open whether detection improves outcomes in prospective trials.
Cohort (n=302)
Atrial fibrillation is common after cardiac surgery, frequently asymptomatic, and often occurs post-discharge, highlighting the potential need for extended outpatient monitoring in high-risk patients.
Funk et al. (2003) conducted a cohort in Post-cardiac surgery (n=302). Cardiac surgery (CABG and/or valve surgery) was evaluated on Incidence of atrial fibrillation. Atrial fibrillation occurred in 42% of patients after cardiac surgery, with 69% of episodes being asymptomatic and many occurring after hospital discharge.
