Dr. Rajeen Pathar (1) and co researchers from Adelaide Australia seem to think so.
Hypertension,diabetes,obesity, sleep apnea and smoking are recognized risk factors for the development of atrial fibrillation (AF).The authors reasoned that the same risk factors might predispose to recurrence of AF after a successful atrial fibrillation ablation and that aggressive risk factor reduction just might decrease the recurrence rate. Their published data (1) tends to support that hypothesis.
A excellent discussion of risk factor importance in AF by Dr. John Mandrola on Medscape can be found here.
