About the mSToPS Study
Researchers at the Scripps Translational Science Institute (STSI) conducted the study in partnership with collaborators, Aetna and Janssen Pharmaceuticals. The innovative study design demonstrated that the digital solution enabled by Zio effectively monitored a large and geographically dispersed population of patients who had risk factors for AF. 

The study involved 5,214 eligible Aetna members who were identified through claims data to have risk factors for AF but had not been previously diagnosed. 1,738 individuals were enrolled via a web-based platform to undergo either immediate or delayed active ECG monitoring at home for up to 4 weeks with a Zio XT patch monitor (two-week monitoring periods spaced four months apart). Each monitored participant was matched with two non-monitored participants with a similar CHA2DS2-VASc, a standardized stroke-risk assessment score, to act as controls. 

The study looked at the time to first diagnosis of AF and its clinical consequences for the active monitoring cohort as well as the cohort undergoing usual care.
