Abstract：
:Venous thromboembolism (VTE) affects approximately 1 per 1000 persons annually. Although patients are increasingly treated with direct oral anticoagulants, many patients continue to be anticoagulated with vitamin K antagonists (VKA). The most important adverse events during VKA treatment, bleeding and the risk of recurrent VTE, are difficult to predict. Global haemostatic assays, such as thrombin generation assays and the viscoelastic whole blood tests thromboelastography (TEG) and thromboelastometry (ROTEM), allow a comprehensive assessment of haemostasis and could potentially predict such side effects. In the present study we compared results from thrombin generation (Calibrated Automated Thrombogram and Innovance ETP assays) and TEG and ROTEM in 84 warfarin-treated patients with primary or recurrent VTE and 87 healthy controls. VKA treatment lead to lagtime prolongation and a lower overall thrombin production, which correlated strongly with INR (Pearson r = 0.89 and r = -0.85, respectively). The reduced thrombin generation of VKA-treated patients was accurately reflected by tissue-factor activated ROTEM (EXTEM) clotting time prolongation (vs. CAT lagtime, r = 0.87). Clot strength or clot formation kinetics were only weakly affected by thrombin generation. Intrinsic pathway activated TEG or ROTEM (INTEM) were not sensitive to the reduced thrombin generation. In conclusion, patients anticoagulated with VKA after VTE showed a reduced plasma thrombin generation that was accurately reflected by tissue factor activated ROTEM. ROTEM provided additional information to thrombin generation, including clot formation kinetics and strength.
