What is the prognostic significance and recurrence risk of new onset atrial fibrillation/flutter in acute pericarditis?
New onset AF/f in acute pericarditis identifies a population with a high recurrence risk (~35%), suggesting these patients should be considered for oral anticoagulation.
The occurrence of AF/f in acute pericarditis identifies a predisposed population to AF/f with a high recurrence risk (about 35%): in these patients, pericarditis may act as an arrhythmic trigger and oral anticoagulation should be seriously considered according to guidelines.
