MHRA launches learning module on oral anticoagulants

Effect of treatment delay, age, and stroke severity on the effects of intravenous thrombolysis with alteplase for acute ischaemic stroke: a meta-analysis of individual patient data from randomised trials

The Lancet
This meta-analysis of individual patient data from 9 RCTs of alteplase for acute ischaemic stroke found that it improved the odds of a good stroke outcome versus control when given within 4.5 hours, with proportional treatment benefits similar regardless of age or stroke severity.

 

Frequent and possibly inappropriate use of combination therapy with an oral anticoagulant and antiplatelet agents in patients with atrial fibrillation in Europe

Heart
This analysis of European registry data found that 10.9% of patients with AF were treated with a combination of oral anticoagulant and one or two antiplatelets. The majority of those on dual (95%) or triple (64%) combination therapy did not have an accepted indication.

 

Perioperative Atrial Fibrillation and the Long-term Risk of Ischemic Stroke

Journal of the American Medical Association
Among patients hospitalised for surgery, perioperative AF was linked to increased long-term risk of ischaemic stroke. More studies are needed to better delineate the risk and determine optimal antithrombotic strategies in such patients with other risk factors for stroke.
