Popis: | Exaggerated procoagulant responses to acute mental stress may contribute to coronary thrombosis, and continuing low-grade systemic coagulation activation may link negative affect with the development of coronary artery disease. We investigated whether negative and positive affect and perceived social support would moderate stress procoagulant reactivity. Psychological functioning, exhaustion, negative affectivity, depression, anxiety, worrying, vigor, and social support were assessed in 27 apparently healthy men (mean age 47 ± 8 years) who underwent the 13-min Trier Social Stress Test combining preparation, speech, and mental arithmetic. Plasma levels of von Willebrand factor antigen (VWF:Ag), fibrinogen, factor VII clotting activity (FVII:C), FVIII:C, FXII:C, and D-dimer were measured immediately before and after stress. Acute stress elicited significant increases in hemodynamic, cortisol, and coagulant activity (p values |
