Association between anxiety and factors of coagulation and fibrinolysis

Psychotherapy and Psychosomatics

Abstract

Psychological stress and anxiety have been shown to produce an activation of coagulation and fibrinolysis. Resulting hypercoagulability is a risk factor for cardiovascular diseases, and could therefore contribute to an increased prevalence of coronary artery disease in anxiety patients. However, hemostasis function has not yet been studied in patients with clinically relevant anxiety disorders. A group of anxiety patients (panic disorder with agoraphobia or social phobia) and a healthy control group (each n = 29) completed some questionnaires [SCL-K9 (a short form of the SCL-90-R), State Trait Anxiety Inventory, ADS (general depression scale)], and had blood drawn after a 15-min rest period. To assess the reaction of the hemostatic system by global entities, sum scores were computed from parameters of coagulation and fibrinolysis (fibrinogen, FVII, FVIII, vWF, F1 + 2, TAT, D-dimer, alpha(2)-AP, PAP, tPA, PAI-1). Interfering variables, such as age, gender, alcohol consumption and smoking status, were controlled. Anxiety patients scored higher in a composite hemostatic score and a sum score of fibrinolysis in comparison to the control group, with a predominant activation of inhibitors in fibrinolysis. However, the psychological v...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
