ABSTRACT
This article reports on the role of anticoagulant therapy in reducing the risk of thrombosis with the lowest possible risk of bleeding. Since the risk of adverse outcome is almost tripled when patients have an international normalized ratio below 2, slowly increasing the dose of vitamin K antagonists should be reconsidered. It mentions that an international normalized ratio of 2-3 is optimal, but ratios that are slightly higher than this therapeutic range are moderately safe and it is likely that the absolute risk of thrombosis and bleeding at a ratio of 3-4 would be lower than 7 percent annually.

    Background: Deep vein thrombosis (DVT) is one of the most common complications of total hip (THA) and total knee arthroplasty (TKA). Though the reported incidence of DVT is very high, that of proximal DVT is low and that of fatal thromboembolism is very low. Hence the issue of prophylaxis for...

    Thrombophilia can best be defined as a disorder of coagulation that contributes to a predisposition towards thrombosis. Although the term thrombophilia has been used to describe arterial thrombosis, its most common usage has been in reference to venous thromboembolism (VTE). Thrombophilia can be...

    Increased factor VIII (FVIII) levels are a prevalent and independent risk factor for venous thromboembolism (VTE). The low density lipoprotein receptor-related protein 1 (LRP1) has been associated with FVIII catabolism. After a median of 10 years of the first thrombotic episode, we evaluated...
