Abstract 4141439: Catheter ablation and clinical outcomes among older Medicare beneficiaries with atrial fibrillation

Cox proportional hazards models were used to estimate hazard ratios (HR) for the composite and individual endpoints from CABANA trial (death, stroke, major bleeding or cardiac arrest) and CASTLE-AF trial (death or heart failure).
