[Temporal evolution of fibrinogen and platelets in reaction to various stressors in coronary and non-coronary subjects (author's transl)].
Twenty-one postmyocardial infarction patients are compared with twenty-one matching non-coronary subjects. Fibrinogen level as well as whole blood platelet count were measured six times for each subject in a timespan of 2 hours, during which two stress situations are induced. Throughout the experiment, non-coronary subjects show significantly lower levels of fibrinogen and higher blood platelet count. These two variables follow a specific temporal evolution. Stressfull situations are directly related with a significant decrease in the whole blood platelet count. Films inducing a directional anxiety match a lower blood platelet count, as compared to films inducing a diffuse anxiety. A link may be hypothesized between the stress-induced decrease in blood platelet count and the relative thrombopenia of coronary patients.
