Johan Engdahl is a Professor of Cardiology and Senior Consultant at the Department of Clinical Sciences, Danderyd Hospital, Karolinska Institutet. His primary affiliation is with the Department of Cardiology at Danderyd Hospital. Engdahl leads a research group focused on improving detection, monitoring, and treatment strategies for atrial fibrillation (AF), particularly through innovative screening methods and digital health technologies.

Research Interests:

• Development of clinical trials with hard endpoints for AF management
• ECG screening methodologies (e.g., STROKESTOP and SMARTBEATS projects)
• Integration of biomarkers and machine learning into AF diagnosis
• Stroke prevention strategies in high-risk populations
• Smartphone-based diagnostics using photoplethysmography

Grants & Projects:

• AF SPICE trial (Swedish Research Council): Evaluates extended ECG monitoring post-stroke/TIA
• CONSIDERING-AF study: Digital AF screening in high-risk groups
• SMARTBEATS: Smartphone PPG heart rhythm diagnostics

Advising & Teams: Supervises doctoral candidates focusing on AF screening protocols and clinical outcomes. Active in thesis evaluations across Scandinavian universities. His team collaborates internationally on cardiovascular registries and device validation studies.

Labs/Teams: Leads the Atrial Fibrillation Research Group at Danderyd Hospital, specializing in translational research between clinical practice and digital health innovations.
