How can stress change the way blood clots?

Stress and clotting: In healthy people, acute mental stress activates clotting within normal physiologic range. In people with atherosclerosis & impaired endothelial function, acute stress may precipitate a hypercoagulable state -- not good. Chronic psychosocial stressors like job strain and poverty also make blood stickier -- hypercoagulable. Depression may cause this too. http://tinyurl.com/ov2fa9l.
