Why the study?
Does renal impairment increase the risk of atrial fibrillation recurrence in patients with persistent atrial fibrillation undergoing successful cardioversion?
Does renal impairment increase the risk of atrial fibrillation recurrence in patients with persistent atrial fibrillation undergoing successful cardioversion?
Impaired renal function is a strong, independent predictor of atrial fibrillation recurrence after successful cardioversion, and maintaining sinus rhythm is associated with improved renal function.
No takes yet. Share an insight, caveat, or question.
Renal impairment may flag higher AF recurrence risk post-cardioversion; leaves open whether optimizing eGFR improves rhythm control in trials.
Schmidt et al. (2011) studied this question.
