Impact of treatment strategies for AF on the progression and regression of AF type in the CABANA trial

Abstract Background The CABANA trial compared drug vs ablation therapy yet did not identify a difference in the primary endpoint of death, stroke, severe bleeding, or cardiac arrest or the secondary endpoint of all-cause mortality by intention to treat (ITT) analysis. Nevertheless, there was evidence of improved outcomes and survival in the as-treated and per-protocol analyses. Objectives To determine how the treatment strategies of drug therapy vs ablation impact the atrial fibrillation progression and regression. Methods CABANA randomized 2204 pts with AF ≥65 yrs old or
