ScienceDaily -- The twin epidemics of obesity and type 2 diabetes will continue to fuel an explosion in heart failure, already the world’s most prevalent chronic cardiovascular disease, according to John McMurray, professor of cardiology at the Western Infirmary, Glasgow, and President of the Heart Failure Association. He reported that around one-third of patients with heart failure have evidence of diabetes, and for them the outlook is very serious. For doctors, he added, effective treatment is “very difficult”.
