Acute stress may heighten thrombotic risk via platelet activation; hypothesis-generating for mechanisms in ischemia.
Do mental and cold pressor stress increase platelet activation and hemoconcentration in healthy men?
Acute psychological and cold stress cause concurrent increases in platelet activation and hemoconcentration, which are related to catecholamine and blood pressure changes and may play key roles in thrombosis and ischemia.
