Does higher body mass index, abdominal fatness, and fat mass increase the risk of atrial fibrillation?
General and abdominal adiposity, as well as higher body fat mass, are associated with an increased risk of atrial fibrillation, even at high-normal BMI levels.
< 0.0001, with a stronger association at higher BMI levels, however, increased risk was observed even at a BMI of 22-24 compared to 20. In conclusion, general and abdominal adiposity and higher body fat mass increase the risk of atrial fibrillation.
