Until recently the standard approach of patients with recent-onset atrial fibrillation (AF) involved early cardioversion. In the latest ESC AF guidelines, a delayed cardioversion approach within 48 hours has been added to the recommendations. However, given the self-terminating and recurrent nature of AF, cardioversion may not always be necessary, and rate control medication could suffice to manage symptoms until spontaneous conversion to sinus rhythm occurs. The Research Continuous heart rhythm monitoring elucidated the recurrent and transient nature of recent-onset atrial fibrillation (AF). In the RACE7 we showed that a wait-and-see approach (WAS) in patients with recent-onset AF (rate control for symptom relief followed by delayed cardioversion if needed <48h) allows spontaneous conversion to sinus rhythm in 69% of patients, obviating active cardioversion. Recurrences within one month were seen in 30% of patients in both groups, i.e. the initially chosen strategy did not affect the recurrence pattern. Considering the latter, it remains unclear whether cardioversion is needed at all, especially since cardioversion strategy does not seem to affect behaviour of the arrhythmia over time. Instead of cardioversion a watchful-waiting rate control strategy may be appropriate as initial strategy. Therefore, we intend to perform a multi-center clinical randomized controlled trial to show non-inferiority of watchful-waiting with rate control versus the WAS approach in terms of prevalence of sinus rhythm at 4 weeks follow-up, using a novel telemonitoring infrastructure to guide rate and rhythm control during follow-up. This novel telemonitoring infrastructure may facilitate the watchful-waiting strategy and obviate the need for cardioversion and reduce costs compared to the delayed rhythm control WAS strategy. The study will be conducted across multiple centers in the Netherlands, including UMC Groningen, Radboud UMC, Amsterdam UMC, Alrijne Hospital, VieCuri Medical Centre, Zuyderland Medical Centre, Elisabeth-TweeSteden Hospital, Rijnstate Hospital, Martini Hospital, St. Antonius Hospital, Antonius Hospital, Noordwest Hospitalgroup, Medisch Spectrum Twente, and Maastricht University Medical Center. Origin This project is funded within the Innovative Medical Devices Initiative (IMDI) program 'Heart for Sustainable Care'. The focus of this program is the development of medical technology for the earlier detection, monitoring, and better treatment of cardiovascular diseases to ensure accessible healthcare and sufficient staffing. The program has been developed en funded by the Dutch Heart Foundation, ZonMw and NWO, who collaborate within the Dutch CardioVascular Alliance.

Promoting a healthy lifestyle and maintaining it for a long time is crucial for the prevention of cardiovascular diseases. Lifestyle change areonly sustainable and impactful if it takes into account the context in which it occurs. The research Therefore, this netwerk will disseminate this insight widely to policymakers, researchers and everyone who contributes to promoting healthy behaviors. In this way, we can collectively achieve greater health gains when implementing potentially successful interventions. The ultimate goal is to achieve sustainable and impactful lifestyle change in the population. In the projects LIKE, BENEFIT and SUPREME NUDGE, unique expertise has been gained in the field of (1) embedding lifestyle interventions in complex systems, and (2) changing systems underlying lifestyle behavior. Within this national network, we want to disseminate and embed this expertise among researchers, practice professionals and policy makers. We will combine this expertise in the form of two toolboxes; a toolbox for practice professionals and policy makers and a toolbox for researchers. To this end, existing tools will be adapted, where necessary, to make them more widely usable. We aim to embed the toolboxes in (existing) structures and will make the toolboxes findable and disseminated through this netwerk. This network will serve as a structure for connections between stakeholders and contribute to the realization of a sustainable knowledge infrastructure. With this project we identify and create important conditions for successful further development and upscaling of innovative and sustainable ways to sustain healthy living for longer. With this we go further than many existing networks and knowledge infrastructures that focus only on 'effective interventions' but not on the structural embedding in systems or addressing the systems themselves. The origin From 2017, the Dutch Heart Foundation, together with ZonMw, invested in research by three healthy living consortia (LIKE, BENEFIT and SUPREME NUDGE). The common goal was to find new ways to achieve sustainable and impactful lifestyle change in the population. Heart Foundation and ZonMw asked the three healthy living consortia Supreme Nudge, LIKE and Benefit to join forces within this theme by using the knowledge they have gained over the past few years. Although the three consortia each had a different approach, the research leaders agreed on what is needed for lifestyle change to be truly successful: a shift in thinking about lifestyle change. Subsequently, the Dutch Heart Foundation and ZonMw provided follow-up funding to join forces and acquired knowledge in a new knowledge infrastructure.
