DISEASE INTERVENTION COMPARISON RESULTS
Am J Med. 2010 Jul;123(7):638-645.e4 Systematic Review
IN anticoagulants, vitamin K antagonists, atrial fibrillation The Use of
frequency of use of anticoagulants, vitamin K antagonists
As Treatment, Chronic
Is worse Than
frequency of use recommended by guidelines
To oral anticoagulants are largely underused in patients with AF and previous AIT or stroke (<70% patients anticoagulated in 25/29 studies, range 19-81%)) or CHADS2 > 2 (<70% patients anticoagulated in 7/9 studies, range 39-92%)
N Engl J Med. 2015 Aug 27;373(9):823-33 Randomized Controlled Trial, Multicenter Study
IN anticoagulants, vitamin K antagonists, atrial fibrillation, periprocedure interruption of anticoagulation The Use of
no bridging anticoagulation, just stopping warfarin 5 days before the procedure and resuming it within 24 hours afterwards
As Treatment, Acute
Is better Than
bridging anticoagulation with full-dose low-molecular-weight heparin (LMWH)
To avoid major bleeding (1.3% just stop Vs 3.2% bridging) while having similar incidence of arterial thromboembolism (0.4% just stop VS 0.3% bridging)
