Calcium Channel Blockers Improve Exercise Capacity and Reduce N-Terminal Pro-B-Type Natriuretic Peptide Levels Compared With Beta-Blockers in Patients With Permanent Atrial Fibrillation

Study Questions:

What are the comparative effects of beta-blockers or non-dihydropyridine calcium channel blockers on exercise capacity and levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with permanent atrial fibrillation (AF)?
