People suffering from coronary artery disease might want to look into overseas health insurance.
This could be especially important if they tend to put on weight around their middle.
According to research from the Mayo Clinic, people with belly fat and coronary artery disease are twice as likely to die as people whose fat collects elsewhere.
Published in the Journal of the American College of Cardiology, the study looked at data from almost 16,000 people involved in five studies around the world.
Francisco Lopez-Jimenez, lead investigator of the project, commented: "Visceral fat has been found to be more metabolically active. It produces more changes in cholesterol, blood pressure and blood sugar.
"However, people who have fat mostly in other locations in the body, specifically, the legs and buttocks, don't show this increased risk."
