Heart failure risk rises with BMI increase

The study, which involved researchers from the Queensland Brain Institute, used a Mendelian randomisation analysis to look at the link between an adiposity-associated variant of the fat-mass- and obesity-associated (FTO) gene and various cardiometabolic traits in 200,000 people.
