Scientist said Sunday they may have unravelled how chronic stress leads to heart attack and stroke: triggering overproduction of disease-fighting white blood cells which can be harmful in excess.

Surplus cells clump together on the inner walls of arteries, restricting blood flow and encouraging the formation of clots that block circulation or break off and travel to another part of the body.

White blood cells “are important to fight infection and healing, but if you have too many of them, or they are in the wrong place, they can be harmful,” said study co-author Matthias Nahrendorf of the Harvard Medical School in Boston.
