Coagulation activation after discontinuation of VTE treatment with different oral anticoagulants and impact on 12-month clinical outcomes

In logistic regression analysis, only ΔTAT (optimal cut-off > 178% from baseline demonstrated a significant risk increase for VTE/death (odds ratio 3.76; 95% confidence interval 1.46-9.68; p = 0.006). In conclusion, the concept of testing coagulation activation parameters may also be transferred to VTE patients at the end of DOAC therapy. For patients with an increase of TAT levels within 4 weeks after treatment discontinuation (> 178% from baseline) is associated with an increased risk for VTE recurrence or death at 12 months.
