RESUMO
In patients with short episodes of clinical, non-triggered AF is the evidence for long-term anticoagulation based on the CHA2DS2-VASc score strong. In situations where a temporary trigger for AF is observed (e.g. after surgery or an infection), or when AF is only detected on a cardiac implantable electronic device (CIED) or smartwatch, the evidence for anticoagulation is less well established. Despite the short duration of the AF episode(s), both patients with subclinical or triggered AF are often at an inherently increased risk of stroke or thromboembolism. In some of these cases long-term anticoagulation can be considered, especially when other cardiovascular risk factors are present. Important considerations when deciding to start with long-term anticoagulation are the individually estimated risk of thrombosis and bleeding, the implementation of shared decision making, and the optimization of the overall cardiovascular risk management.
