摘要
Aims In the Far East, there has generally been low uptake of oral anticoagulants (OACs) using vitamin K antagonists (VKA, e.g. warfarin) for stroke prevention in atrial fibrillation (AF), but OAC use has been increasing more recently, with the introduction of the non-vitamin K antagonist oral anticoagulants (NOACs). To explore the risks of ischaemic stroke (IS) and death related to AF in East Asia using modelling projections. @@@ Methods and results We performed a modelling analysis of possible trends of IS and death rates in AF patients from the time period of only VKA use to current increasing trends of NOAC use projecting until 2050 in East Asia. Data from published articles on the prevalence of AF, IS, and death were used to model estimated event rates. In 2030, the estimated AF population in East Asia will be 608 100, with the use of NOACs leading to a reduction of 82 259 ISs and 16 917 deaths. There was an estimated annual risk reduction of 5484 ISs and 1128 deaths from 2016 to 2030, respectively. The AF population is estimated to reach 861 900 in 2050, with a reduction of 206 315 ISs and 139 353 deaths. @@@ Conclusion This modelling analysis suggests that the transition from VKA to NOACs may greatly help in reducing the burden of IS and death caused by AF in the East Asian region.
