Long-term benefits of preventing venous thromboembolic events.
Summary of "Long-term benefits of preventing venous thromboembolic events."
Abstract Background: Venous thromboembolism (VTE) and its long-term secondary complications are major health problems associated with high rates of morbidity and mortality and considerable costs for healthcare systems. Many patients receive suboptimal therapy, despite the availability of established and effective agents (including low molecular weight heparins, unfractionated heparin, fondaparinux and vitamin K antagonists) and evidence-based, internationally recognised guidelines. Limited knowledge of guidelines, concerns about bleeding risks and the inconvenience of parenteral administration and routine coagulation monitoring contribute to non-adherence to guidelines. Newer oral anticoagulants such as rivaroxaban, dabigatran etexilate, apixaban and edoxaban, which do not have the limitations of established anticoagulants, have been developed. Method: Phase III randomised controlled trials for the treatment of acute VTE or for secondary prevention of recurrent VTE were identified in the PubMed and ClinicalTrials.gov databases. The search was limited to phase III studies and performed up to 26 March 2012 with the terms "rivaroxaban OR Xarelto", "dabigatran OR Pradaxa", "apixaban OR Eliquis" and "edoxaban OR DU-176b OR Lixiana". Findings: A total of 10 phase III studies, four published (three rivaroxaban, one dabigatran), three completed with results presented at recent congresses (dabigatran), and three ongoing (two apixaban, one edoxaban) were identified. Published and completed studies showed that rivaroxaban and dabigatran provided effective and convenient short-term treatment for deep vein thrombosis and VTE, respectively, when compared with standard of care, and showed superiority for long-term prevention of recurrent VTE when compared with placebo. Currently, rivaroxaban is the only newer anticoagulant that has been approved in Europe for the treatment of deep vein thrombosis and prevention of recurrent VTE. Conclusions: Based on results of completed trials, rivaroxaban and dabigatran both may reduce the incidence of secondary complications of VTE and associated socioeconomic costs. Introduction of these newer anticoagulants is likely to have a substantial impact on clinical practice.

Insurance, Long-term Care
Health insurance to provide full or partial coverage for long-term home care services or for long-term nursing care provided in a residential facility such as a nursing home.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Hiv Long-term Survivors
Persons who have experienced prolonged survival of HIV infection. This includes the full spectrum of untreated, HIV-infected long-term asymptomatics to those with AIDS who have survived due to successful treatment.
A persistent increase in synaptic efficacy, usually induced by appropriate activation of the same synapses. The phenomenological properties of long-term potentiation suggest that it may be a cellular mechanism of learning and memory.
Long-term Synaptic Depression
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.

Background The use of recombinant activated factor VII (rFVIIa) on an off-label basis to treat life-threatening bleeding has been associated with a perceived increased risk of thromboembolic complicat...
Warfarin is the predominant oral anticoagulant used for the prevention of recurrent venous thromboembolism (VTE) events. However, its long-term use is complicated by the need to manage the drug within...

Patients with provoked venous thromboembolism caused by transient risk factors can generally stop anticoagulation after 3 months of treatment. For patients with unprovoked venous thromboembolism, for...
