Rivaroxaban should also be considered for the treatment of patients at high risk of stroke or who have suffered a previous TIA/stroke. The ROCKET-AF trial enrolled a cohort of patients at higher baseline risk of stroke (mean CHADS2 score of 3.5) and more patients who had suffered a previous stroke or TIA (55%) compared to the other NOAC trials [22]. Consequently, although it is clear that rivaroxaban is noninferior to warfarin in the prevention of stroke and systemic embolism in this cohort, further studies may be necessary to fully address the relative benefit of rivaroxaban compared to warfarin and other NOACs in patients at low risk of stroke (CHADS2 score of 0–1).
