The Current Model for Recognition and Modification of Risk Factors for Atrial Fibrillation is Ineffective

Introduction: There is growing data that successful modification of risk factors (RF) for atrial fibrillation (AF) can significantly improve the outcomes of AF therapies. These RFs include obesity, exercise, hypertension, diabetes, cholesterol, smoking, and obstructive sleep apnea (OSA). RF modification has mostly been delegated out of electrophysiology clinics to primary care providers. Hypothesis: The current model for recognition and modification of RF for AF is suboptimal. Methods: Consecutive patients referred to the University of Virginia for initial ablation of paroxysmal or persistent AF with a minimum of 90 days of follow-up since September 2010 were included in this study. RFs were compared immediately pre- and at latest follow-up post ablation. RFs included body mass index (BMI), hypertension, treated obstructive sleep apnea, Type 1 or 2 diabetes, lipid profile and smoking. Results: Of 1750 ablation patients, 1190 met inclusion criteria. Mean age at ablation was 64 years, 63% male, mean LA dime...
