Study covered systemic hemostasis in 69 males aged 47.6 +/- 2.1 years with 1 stage arterial hypertension and 1 stage vibration disease, exposed to various types of occupational vibration at work. Those exposed to bump vibration demonstrated an increase in platelets aggregation with all aggregation inductors, if compared to reference values, increased generaton and activity of von Willebrand factor, moderately depressed fibrinolysis system with increased serum content of fibrin and fibrinogen degradation products and decreased anticoagulation factors activity. Those exposed to rotation vibration demonstrated less changes.
