Obesity may predict bleeding during warfarin treatment

Adults with obesity have an elevated risk for bleeding while assigned warfarin therapy compared with adults who are normal weight, researchers reported at the American Heart Association’s Arteriosclerosis, Thrombosis and Vascular Biology/Peripheral Vascular Disease Scientific Sessions.Researchers examined the association between BMI and bleeding in a study of 863 patients assigned warfarin who came to an anticoagulation clinic during a 1-year period. The mean age of the patients was 69 years and 44% were women. The researchers calculated CHA2DS2-VASc scores for each patient and documented major and minor bleeding events.
