Facts and studies

From the first concept to the evaluation and continuous refinement, Preventicus has been working closely with cardiologists, scientists, engineers, patients, and population health experts. For us, the guiding principle has always been on matching medical knowledge with what digital technologies offer today.

Scientific research demonstrates the legitimacy of the use of the Preventicus® Heartbeats App and Preventicus Nightwatch® for stroke prevention. In the most recent international studies on over 1,300 participants (Watch AF and Detect AF Pro), it was shown that the app detected atrial fibrillation (AF) with an accuracy of approx. 96%. The positive predictive value was over 99%, which means that two independent cardiologists subsequently confirmed AF recognized by the Preventicus Heartbeats App in over 99% of the cases.

Cutting-edge research projects by the European Union


Preventicus is supported by two of the European Union's Horizon 2020 research projects (SME Instruments Phase II and Eurostars). Horizon 2020 is the European Union's framework program for research and innovation. This funding program aims to build an EU-wide association built on science and innovation and a competitive economy and, at the same time, contribute to sustainable development. The Horizon 2020 funding project (SME Instruments Phase II) "RedStroke" (Reducing Stroke in Europe) enables Europe-wide clinical studies based on Preventicus technology.

RedStroke - Reducing Europe's Stroke Incidence: Highly Cost-effective Population Screening Programs for Atrial Fibrillation Coupled With High Diagnostic Yield Confirmation Services

The RedStroke study is currently being conducted in seven European countries (estimated study completion date: Dec. 31, 2020). In this study, the effect of a smartphone application in detecting AF will be assessed in a double-blind randomized controlled multicenter trial.

Economic impact

The Managed Care model was assessed from a health-economic perspective: the analysis revealed the positive cost-effectiveness within approximately three years for statutory health insurance providers in Germany. For private health insurance companies, this can be achieved within approximately five years. Please note that Germany is the most complex payor market in the European Union.
