Comparison of Long-Term Risk Adverse Outcomes In Patients with Atrial Fibrillation Having Ablation vs Antiarrhythmic Medications

The impact of atrial fibrillation (AF) catheter ablation vs. chronic antiarrhythmic therapy alone on clinical outcomes such as death and stroke remains unclear. We compared adverse outcomes for AF ablation versus chronic antiarrhythmic therapy in 1070 adults with AF treated between 2010 and 2014 in the Kaiser Permanente Northern California and Southern California healthcare delivery systems. Patients undergoing AF catheter ablation were matched to patients treated with only antiarrhythmic medications, based on age, gender, history of heart failure, history of coronary heart disease, history of hypertension, history of diabetes, and high-dimensional propensity score.
