肥胖和房颤(AF)是日益严峻的公共健康挑战。研究发现随着体质量指数(BMI)增加,发生AF的风险随之上升。减重不仅对于肥胖、高血压、糖耐量受损、糖尿病及阻塞性睡眠呼吸障碍等心血管危险因素皆能发挥有利效应,还可以有效改善肥胖引起的心房结构重构及电生理改变等AF发生及进展的基础因素。严谨的体质量管理策略可以有效减少AF负担。 Obesity and atrial fibrillation (AF) are increasingly serious public health challenges. The study found that as body mass index (BMI) increased, the risk of AF increased. Weight loss is not only beneficial to cardiovascular risk factors such as obesity, hypertension, impaired glucose tolerance, diabetes mellitus and obstructive sleep apnea, but also can effectively ameliorate obesity caused atrial structural remodeling and electrophysiological changes such as AF And the basic factors of progress. Stringent body mass management strategies can effectively reduce the AF burden.
