Summary

Anticoagulants influence either coagulation, inflammation and inflammatory processes in deep vein thrombosis (DVT). Acute DVT cause an inflammatory response that may persist for a long period of time. There is a need to describe patterns of change in serum biomarker levels after acute DVT, and explore the association between trajectory biological patterns and clinical evolution in the era of various anticoagulants in the acute phase of treatment in order to be able to further avoid recurrence and late sequelae. It appears that direct oral anticoagulants and heparin alter inflammatory markers in different ways. It is therefore important to study the evolution of markers according to the different treatments used and secondarily to compare them with each other. Tinzaparin is used in the long term in patients with DVT, it is necessary to measure the evolution of inflammatory markers and then in another study to compare with the other molecules.
