Overweight is associated with improved survival and outcomes in patients with atrial fibrillation

Abstract

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.

Is There an Obesity Paradox for Outcomes in Atrial Fibrillation?

“…21 Four observational studies were based on Asian populations. [17][18][19]23 In 12 out of 13 studies, the mean age progressively decreased with higher BMI categories, with the study by Overvad et al 16 being the exception (Table). In 2016 alone, 6 other studies were published examining the relationship of BMI with outcomes in AF.…”

“…[16][17][18][19][20][21][22][23] One study included AF patients who underwent an ablation procedure for rhythm control strategy. 21 Four observational studies were based on Asian populations.…”

Is Low Body Weight a Novel Risk Factor for Thromboembolic Events in Patients With Non-Valvular Atrial Fibrillation?

“…9 However, the incidence of stroke in their population was not associated with BMI. Accordingly, the report by Hamatani et al provides the first evidence that LBW is associated with the highly increased incidence of thromboembolic events observed in NVAF patients.…”

The year in cardiology 2016: arrhythmias and cardiac implantable electronic devices

“…Nijedan stupanj povećanja tjelesne težine nije bio povezan s različitim rizikom od krvarenja. Jedno od mogućih objašnjenja navedenih rezultata jest ranija i rigoroznija uporaba dodatnih lijekova, promjena životnoga stila 19 te bolja metabolička rezerva 20 koja u konačnici može utjecati na srednjoročnu prognozu u pretilih bolesnika.…”

“…No measure of adiposity was associated with a different risk of bleeding. Among possible explanations for this finding are an earlier more rigorous use of co-medications and life-style modification 19 and better metabolic reserve, 20 which may ultimately affect intermediateterm prognosis in obese patients.…”
