Obesity, diabetes fuel heart failure risk
The twin epidemics of obesity and type 2 diabetes will fuel an explosion in heart failure, researchers in Scotland suggest.
John McMurray, professor of cardiology at the Western Infirmary in Glasgow, Scotland, said about one-third of patients with heart failure have evidence of diabetes, and for them the outlook is very serious and effective treatment is
Obesity is at least as great a risk factor for heart failure as it is for heart attack or stroke, McMurray says in a statement.
Obesity more than doubles the risk.
The pathways by which obesity plays such a role in heart failure are not yet fully understood, but have been shown to have an indirect effect through hypertension, heart attack or diabetes -- and a direct effect on the heart muscle itself, McMurray says.
The finding was presented at the Heart Failure Congress in Nice, France.
