Atrial contractility and fibrotic biomarkers are associated with atrial fibrillation after elective coronary artery bypass grafting.
New-onset postoperative atrial fibrillation is common after cardiac surgery. Less has been reported about the relationship among fibrosis, inflammation, calcium-induced left atrial and right atrial contractile forces, and postoperative atrial fibrillation. We sought to identify predictors of postoperative atrial fibrillation. ⋯ Advanced age, decreased left atrial force value at calcium-induced force measurement of 5.5, enlarged left atrial and right atrial areas, and reduced tricuspid annular plane systolic excursion were identified as independent predictors for postoperative atrial fibrillation.

Persistence of risk of death after hospital discharge to locations other than home after cardiac surgery.
Temporal changes in the risk of postoperative death following cardiac surgery are uncharacterized. We aimed to quantify the duration of postoperative phase with elevated risk of death in patients who underwent cardiac surgery and were discharged to home and destinations other than home. ⋯ Hospital discharges to locations other than home following cardiac surgery were associated with an increased risk of late mortality. The postoperative high-risk phase persisted for 80 days in patients who were discharged to locations other than home, supporting the use of 90-day outcome measures as quality metrics. Predictors of discharge to locations other than home were identified, and this may aid in selective intervention to reduce the risk of death in this vulnerable patient population.
