Long lasting sitting position and haemostasis.
Blood coagulation, fibrinolysis and platelet aggregability were assessed in 8 physicians aged 30-40 years, who had travelled non-stop by car from Salonica to Athens (510 km) and returned to Salonica after 48 h of rest and after administration of 1 g of aspirin. At the end of journey A, platelet aggregability was found to be increased (6 out of 8 persons), AT III was decreased by 30% (p less than 0.001), the F VIII:C / F VIIIR: Ag ratio was decreased (p less than 0.02) and ELT was prolonged. At the end of journey B the findings were the following: platelet aggregation was not affected, the decrease of AT III was not statistically significant and ELT was significantly shortened (p less than 0.005). A common finding of both journeys was the increase of platelet counts at the end (p less than 0.005). The correlation between long lasting sitting and the response of the haemostatic balance is suggested. The influence of aspirin is discussed.
