Study summary

Cardiac thromboembolism attributed to atrial fibrillation (AF) constitutes at least one-third of ischemic strokes. Indeed, stroke may be the first manifestation of previously undetected AF. The prevalence is projected to increase 20% the coming decades, especially in age group 65 years and above of age. To add to incidence, the diabetic population have an increased risk yet not properly investigated. In patients with confirmed AF, assessment using the CHA2DS2-VASc score (congestive heart failure, hypertension, age 65 years and above, diabetes mellitus, stroke, vascular disease, age 75 years and above, sexual category), is applied for risk stratification. If the CHA2DS2-VASc score is at least 1, or definitely 2 points typically a non-vitamin K antagonist oral anticoagulant (NOAC) should be prescribed. The chest- and thumb-electrocardiogram (ECG) system Coala Heart Monitor has proven efficacious in detecting AF following recent cryptogenic stroke. This system also showed to be feasible from a patient perspective. Thus, in patients aged 65 years and above with diabetes mellitus at least 2 points are reached. Therefore, patient with these risk factors should be considered for further evaluation for NOAC to prevent stroke, which provides the rational for this study.

What researchers measure

Primary outcomes

  1. Number of participants with the diagnosis of atrial fibrillation

    Incidence of atrial fibrillation during the monitoring period

    Time frame: 90 days

Secondary outcomes

  1. Patient-reported symptoms (descriptive category variables) of atrial fibrillation using a questionnaire in a digital application

    Symptoms (questionnaire with the following categories of answers: palpitation, dizziness, dyspnea, chest pain, other) when atrial fibrillation is diagnosed using the patient report (in the digital application with the mentioned categories of symptoms predefined) at the time of ECG transmission.

    Time frame: 90 days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2021 (actual). Primary completion is estimated for Apr 2022, 7 months after the start.

Of 533 non-industry observational studies under Diabetes Mellitus, half reached primary completion within 42 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 175. This study's planned 7 months is below that.

Counting every sponsor, half of 642 studies reached it within 36 months; a quarter within 14 and three quarters within 122.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 30, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
