AF is the leading cause of stroke, and by comparison to other types of stroke,2 AF-related stroke is more severe; yet highly preventable. Although we have overwhelming evidence that oral anticoagulation (OAC) is highly effective in preventing stroke in patients with AF,3 therapy has remained underused until recently.
In their Heart paper, Adderley et al4 report the results of temporal trends in age-sex standardised AF prevalence and use of stroke prevention therapy among 744 primary care practices across the UK from 2000 to 2016. Once again, this demonstrates the value of high-quality (and very large) data sets utilising data from a practice rather than a hospital level, the authors are able to characterise over 5 million individuals with AF.
