A new study suggests that high blood sugar can cause stronger contractions of blood vessels, increasing the risk of complications in heart attack patients. Researcher Dr. Richard Rainbow explains, “This is the first study to show direct evidence of blood vessel contraction to glucose, and the potential mechanism behind this contractile response. In the experimental models we used in this study, including human blood vessels, increasing glucose to the levels that could be reached after a large meal altered vascular contraction.”
