They found a decreased ability of blood vessels to relax resulted from increased activity of a natural mechanism for altering protein form and function, says Dr. Rita C.Tostes, physiologist in the MCG School of Medicine.
The researchers suspect increased modification of proteins by a glucose-derived molecule is a player in vascular problems associated with hypertension, stroke and obesity as well.
One aftermath of high glucose levels is low levels of the powerful vasodilator nitric oxide in blood vessels, a shortfall that increases the risk of high blood pressure and eventual narrowing of the vessels, researchers reported at the American Society of Hypertension 24th Annual Scientific Program in San Francisco during a joint session with the Council for High Blood Pressure.
"We know diabetes is a major risk factor for cardiovascular disease and we think this is one of the reasons," Dr. Tostes says.
Diabetes increases the risk of cardiovascular disease such as heart disease and stroke, even when glucose, or blood sugar, levels are under control. In fact, about 75 percent of people with diabetes die from some form of heart or blood vessel disease, according to the American Heart Association.
