Increase in utilization of guideline-recommended therapies in an implementation project: the Atrial Fibrillation registry. Use of guideline-recommended therapies at baseline, 12 months, and 24 months in the longitudinal cohort. ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker, CRT, cardiac resynchronization therapy; CRT-P, CRT with pacemaker; CRT-D, CRT with defibrillator; HF, heart failure. *P < 0.001, 12 and 24 months versus baseline. †P < 0.001, 12 versus 24 months. ‡P = 0.007, 12 versus 24 months. §P = 0.009, 12 versus 24 months.
