Inflammation may be the reason high blood sugar levels damage blood vessels, raising the possibility that anti-inflammatory medications might someday be used to lower the risk of blood vessel disease in people with diabetes, according to a study presented at the American Heart Association's High Blood Pressure Research Scientific Sessions 2014.
"These findings may explain why good blood sugar control is not sufficient to avoid the development of diabetes-induced cardiovascular diseases," said Carlos F. Sánchez-Ferrer, M.D., Ph.D., study author and professor of pharmacology at the Universidad Autónoma de Madrid, Spain. "We need to find new medications focused on reducing inflammation."
Using cultured smooth muscle cells from the main human artery (aorta), researchers found:
"We need to reduce the inflammatory environment associated with diabetes," Sánchez-Ferrer said. "Changes in life-style, such as physical exercise and weight reduction, are important not only because they reduce blood sugar but because they reduce inflammation."
The researchers plan to test whether the effect is similar in cultured cells from the lining of blood vessels and explore the blood sugar/inflammation connection in animals.
