NCT04108884

Brief Summary

In the RedStroke study, the effect of a smartphone application in detecting Atrial Fibrillation (AF) will be assessed in a double-blind randomised controlled multicenter trial. Outpatients with an elevated risk for atrial fibrillation will be randomized to an intervention arm (app group) and to a standard-of-care arm (control group). Both groups will have the app installed on their private smartphones and will be asked to perform a predefined measurement protocol. All patients will continue their prior therapy with their general practitioner and obtain every medical treatment indicated. This study will not cause any restrictions on the usual treatment of the study patients. The only difference between the two groups will be, that patients in the app group will be informed by their local PI, if the recordings of the app indicate AF (and obtain a 14 day Holter ECG for AF verification), whereas the patients in the "usual care" group will obtain the read out of the app at the end of the study.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of Atrial Fibrillation

    Prevalence of Atrial Fibrillation confirmed by ECG in the app group compared with the standard care group

    6 months

Secondary Outcomes (2)

  • Costs related to the AF screening

    6 months

  • Compliance of patients using the app

    6 months

Study Arms (2)

App Group

EXPERIMENTAL

In the app group, if an episode of arrhythmia is detected with the app, the local investigator will contact the respective patient to schedule an appointment for a 14 day Holter ECG.

Device: App measurementDevice: 14 day Holter ECG

Standard Care Group

OTHER

The control group will perform the same measurements as the intervention group, with the only difference that a cumulated Portable Document Format (PDF) report is provided after 6 months instead of the immediate feedback in the app group.

Device: App measurement

Interventions

App measurement twice a day in the first two weeks after enrollment and twice a week (on different days) from the third week onward and whenever patients feel palpitations

App GroupStandard Care Group

14 day moblie patch Holter ECG for AF confirmation

App Group
