miR-21 may noninvasively mark atrial fibrosis extent; hypothesis-generating for ablation outcome prediction in persistent AF.
Does circulating miR-21 correlate with left atrial low-voltage areas and predict procedure outcome in patients with persistent atrial fibrillation undergoing ablation?
Circulating miR-21 may serve as a noninvasive biomarker for the extent of left atrial fibrosis (low-voltage areas) and predict ablation success in patients with persistent AF.
