Here’s one more reason folks living with diabetes or pre-diabetes should take care of their cardiovascular health. New findings published in the journal of British Pharmacology show high blood sugar levels may trigger more severe blockages in arteries that are already blocked, and potentially cause a patient to suffer complications after a heart attack or stroke, HealthDay reports. A heart attack occurs when an artery that provides blood to the heart is blocked. A stroke can happen the same way, except the blockage occurs in arteries that supply blood to the brain. Both can be fatal. What’s more, past research shows that both events are also more common among people suffering from diabetes. To help better understand how diabetes affects the arteries of people suffering from this metabolic illness, a team of scientists at the University of Leicester in England conducted a controlled lab study to see exactly how sugar, or glucose, in the blood can change the behavior of these vital blood vessels.
