体重指数(BMI)对心房颤动(简称房颤)患者预后(卒中/栓塞、心血管死亡、全因死亡及出血)的影响存在争议。既往有研究提出肥胖是房颤患者发病起始、复发和进展中的一个独立危险因素。然而,近年又有研究指出,在房颤患者中,低体重与卒中/栓塞、心血管死亡、全因死亡及出血的风险增加有关,而超重/肥胖可降低这些风险,并将这一现象称为“肥胖悖论”。
The impact of body mass index (BMI) on the prognosis of patients with atrial fibrillation (stroke / embolism, cardiovascular death, all-cause mortality and hemorrhage) is controversial. Previous studies have suggested that obesity is an independent risk factor for the onset, relapse and progression of AF in patients with AF. However, recent studies have shown that low body weight is associated with increased risk of stroke / embolism, cardiovascular death, all-cause mortality and bleeding in patients with AF, and overweight / obesity reduces these risks and calls this phenomenon For “fat paradox ”.
