Abstract
Anthony W Austin Stephen M Patterson Roland von Känel Hemoconcentration and Hemostasis During Acute Stress Interacting and Independent Effects Annals of Behavioral Medicine Volume 42 Issue 2 October 2011 Pages 153–173 https//doiorg/101007/s1216001192740Acute psychological stress can produce significant hemoconcentration as well as prothrombotic changes in blood both of which may have potentially harmful effects on the cardiovascular system It is unclear whether these effects are independent or have influence on each otherThis review discusses research investigating the effects of acute psychological stress on hemoconcentration and hemostasis and explores future directions for psychohematology research Physiology associations with cardiovascular disease and relationships between acute psychological stress are discussed independently for hemoconcentration and hemostasis followed by an examination of the effects of stresshemoconcentration on hemostasisTraditional methods of adjusting for stresshemoconcentration effects eg calculated plasma volume or hematocrit level corrections may not be appropriate when examining stressinduced changes in hemostasis The effects of acute stress on hemostasis should be examined in conjunction with hemoconcentration
