ImpactModerate impact

The social discussions seem to recognize the significance of the research for clinical decision-making, but do not promote immediate changes in practice.

Abstract in brief

  • A meta-analysis of 29 randomized trials involving over 28,000 patients with nonvalvular atrial fibrillation shows that both adjusted-dose warfarin and antiplatelet agents significantly reduce the risk of stroke, with warfarin being about 40% more effective than antiplatelet therapy.
  • The study found that warfarin reduces stroke risk by approximately 60%, while antiplatelet agents reduce it by about 20%, and increases in major bleeding are small across treatments.
  • Methodological differences among studies varied, but overall findings suggest that anticoagulation with warfarin provides superior stroke prevention compared to antiplatelet therapy in patients with atrial fibrillation.]

ワルファリンは適切に管理されていれば安全性も高く、脳卒中もしくは全身性塞栓症リスクを6割ほど低下させる 。そのベネフィットは、出血リスクを考慮してもなお大きい 。 https://t.co/yGYq5Wmv0c https://t.co/mzLI1vDpkh https://t.co/d6JMQodyyp

13/15 Third point – what is the estimated risk reduction by using anticoagulation x placebo ? The best available data would be for the trials that compared warfarin x placebo. Again, going for meta-analysis data (https://t.co/LGWTOsLU7i) we have this figure: https://t.co/RZOrODVCnZ

5b) #Warfarin has been known to greatly attenuate #stroke risk for years (meta-analysis at https://t.co/NHPBcjWqcG), but for almost as long there has also been limited provider adherence to guidelines and patient compliance with warfarin.

3/15 The first point that crossed my mind when someone spoke at “intermediate” was the history of Aspirin for stroke prevention in Afib. Let’s that a look at that evidence – a meta-analysis published in 2007 by Hart and colleagues (https://t.co/LGWTOsLU7i)
