Multicenter Study
Overweight is associated with improved survival and outcomes in patients with atrial fibrillation.
The aim of this study was to investigate the association of body mass index (BMI) with mortality and cardiovascular events in Chinese patients with atrial fibrillation (AF). ⋯ Obesity and overweight were not risk factors for 12-month mortality in Chinese AF patients. Overweight AF patients have better survival and outcomes than normal weight (BMI 18.5-24 kg/m(2)) and underweight patients.
