Study Summary

REACT-AF is a multicenter prospective, randomized, open-label, blinded endpoint (PROBE design), controlled trial comparing the current Standard Of Care (SOC) of continuous Direct Oral Anticoagulation (DOAC) use versus time-delimited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) in participants with a history of paroxysmal or persistent Atrial Fibrillation (AF) and low-to-moderate stroke risk.

Primary Outcome

The primary objective (efficacy objective) of the REACT-AF trial is to assess whether AFSW-guided, time-delimited DOAC therapy is non-inferior to continuous DOAC therapy for a composite endpoint that includes: (1) Ischemic stroke; (2) Systemic embolism; and (3) All-cause mortality. Stroke is defined as an acute episode of focal or global neurological dysfunction caused by brain, spinal cord, or retinal vascular injury as a result of hemorrhage or infarction; and classified as ischemic, hemorrha
