[Hemostasis suppression by a combination of heparin and acetylsalicylic acid]
The effect of a combined application of acetylsalicylic acid and heparin on haemostasis is examined on 7 healthy test persons. Apart from the change of the plasmatic coagulation and the platelet function by the pharmaca a prolongation of the bleeding time which is larger than the values of the individual application can be established. In the in-vitro-experiment could be proved that the prolonged bleeding time is based on the prevented by acetylsalicylic acid release of the heparin neutralising factor 4 from the platelets. An improvement of the therapeutic effect of heparin when at the same time acetylsalicylic acid is given is discussed.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
