Researchers are looking closely at what they believe links chronic stress and heart attacks: an overproduction of white blood cells.
The body makes an excess of white blood cells during times of stress. The white blood cells, or leukocytes, are important for fighting infection, "but if you have too many of them, or they are in the wrong place, they can be harmful," Matthias Nahrendorf of Harvard Medical School, a co-author of the study, told Agence France-Presse. The cells can stick to artery walls, restricting blood flow and helping form blood clots.
