  • Obesity may cause cardiac electrical and structural remodeling, increasing the predisposition to AF; this is an underlying pathophysiology that is not well understood.

  • Their clearance was also higher than that found in people who had never been obese, suggesting that a post-bariatric surgery patient would need a higher dose than typically given [12].
