Overweight patients are more at risk to experience a return of atrial fibrillation, a heart rhythm disorder, after a corrective procedure compared to those with normal weight, showed the latest research presented at European Society of Cardiology’s EHRA 2022. The research used Danish nationwide registries, which included a total of 9,229 adults who underwent a first-time atrial fibrillation from 2010 through 2018 to find that, as compared to the normal weight group, the overweight, obese and morbidly obese groups had a 19 percent, 22 percent and 32 percent higher likelihood of atrial fibrillation respectively.
