About me

  • I hold a position as senior consultant, Department of Cardiology at Danderyds University Hospital and as associate professor at the Department of Clinical Sciences, Karolinska Institutet at the same hospital. Our research group is dedicated to improve stroke prevention among patients
    with atrial fibrillation, partly by studying ECG screening and alternative ways of detecting patients with atrial fibrillation.


  • The majority of our projects are clinical trials, many of them with hard clinical endpoints. One of the landmark studies on atrial fibrillation screening, STROKESTOP (NCT01593553), was performed by our group. The biomarker-enhanced STROKESTOP II (NCT02743416) will report the primary endpoint during 2024. A randomised clinical trial on AF detection post stroke (AF SPICE, NCT05134454) is recruiting from 26 stroke units in Sweden. Further projects include developement and implementation of smartphone PPG heart rhythm diagnosis (SMARTBEATS, NCT04300270), digital, siteless and risk prediction model-enhanced atrial fibrillation screening in high-risk groups (CONSIDERING-AF, NCT05838781), the relation between excessive supraventricular activity and atrial fibrillation (ESA AF, NCT04593498) and a longitudinal study on progression of atrial fibrllation in the young (PRAY, NCT05080712).
