Brief Summary

Atrial fibrillation (AF) is the most common arrhythmia and a common cause of stroke. AF can be asymptomatic and remain undiagnosed. Both the prevalence of AF and the proportion of strokes related to undetected AF increases with ageing. If AF is timely diagnosed and treated accordingly with anticoagulants, disabling strokes can be prevented. In order to help physicians in diagnosing atrial fibrillation, the MyDiagnostick was developed. It is a CE certified device that is safe, user friendly and easy to use. This device is capable of detecting or excluding AF within one minute by providing a registration of lead I of the ECG. The investigators aim to perform a 2-arm cluster randomized diagnostic trial among patients aged 65 years and over who visit the general practice. In total the investigators will include 42 general practices of which they randomly assign 21 to the MyDiagnostick arm and 21 to the control arm. All persons aged 65 years and over who visit the general practice in the MyDiagnostick arm will be asked to hold the device every time they visit the surgery during one year. The number of newly detected cases of AF with the diagnostic screening strategy with MyDiagnostick (MyDiagnostick arm) will be compared to care as usual (control arm). Also, the number of patients treated with anticoagulants according CHA2DS2-VASc score will be compared between both arms. Finally, the investigators will assess the number of major adverse cardiovascular events (MACE), intracerebral hemorrhages and other major hemorrhages, and all-cause mortality between the arms. End points will be assessed blinded to allocation. The investigators hypothesise that the MyDiagnostick improves the diagnosis of atrial fibrillation in primary care and with accordingly treatment will reduce adverse outcomes.

Outcome Measures

Primary Outcomes (1)

  • Newly detected cases of AF

    For our primary outcome the investigators will calculate the number of atrial fibrillation as detected with MyDiagnostick (MyDiagnostick arm) as compared to care as usual in primary care (control arm)

    One year

Secondary Outcomes (2)

  • Adequate treatment of AF according the CHA2DS2-VASc score

    one year

  • Major cardiovascular events and all cause mortality

    one year

Study Arms (2)

MyDiagnostick

ACTIVE COMPARATOR

Everyone aged 65 years or over, who visits the GP practice will be screened for AF with the MyDiagnostick. When the device indicates a positive result, the single lead ECG will be assessed to confirm/reject the diagnosis. Every new case of diagnosed AF will be evaluated for further treatment by the general practitioner.

Device: MyDiagnostick

Control

NO INTERVENTION

Control arm will perform care as usual with selective screening by feeling the pulse.

Eligibility Criteria

Age65 Years+
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • Community dwelling persons visit the GP and aged 65 years of over

You may not qualify if:

  • Terminal illness of such severity that anticoagulation is considered to be not appropriate in case of newly detected atrial fibrillation
  • Acute situation in which GP should act instantly
  • Patients with a history of AF
