Atrial fibrillation (AF) is not benign. It commonly progresses from paroxysmal AF (PAF) to permanent AF. AF progression is associated with major adverse cardiovascular/cerebral events (MACCE). Cardiovascular risk factors and comorbidities (CVR) are present long before the first AF episode, causing a progressive atrial cardiomyopathy (ACM). The mechanisms of ACM vary between patients hindering effective AF management. The EmbRACE network now aims to unravel the diversity of mechanisms underlying ACM, identify simple diagnostic tools to identify them, and develop a therapeutic approach to prevent ACM progression. The Research Early rhythm-control therapy is one promising intervention to potentially interfere with ACM progression next to CVR management. For a sustained impact we aim to develop care pathways to prevent ACM and AF progression and MACCE. Therefore, we will identify and validate relevant cellular and molecular determinants of ACM and AF and their clinical surrogate parameters; develop an in-silico platform to simulate identified mechanisms of ACM and AF and their effects on AF progression and, based on these data, make suggestions for future refinement of ACM therapy; explore the variety of temporal patterns of PAF as markers of ACM subtypes, demonstrate their prognostic relevance and identify surrogate markers available in clinical practice, based on AI and machine learning; test in a randomized trial stratified for sex the hypothesis that early AF ablation and optimal CVR management in AF patients with ACM delays ACM progression and reduces MACCE; explore whether lifestyle management reduces ACM progression, whereas with only rate control ACM progresses; validate the RACE V AF progression score in real life cohorts and translate this and other knowledge into novel care pathways for AF. The origin Atrial fibrillation is the most common cardiac arrhythmia and can lead to a variety of complications, such as stroke. Currently, there are limited treatment options for this cardiac arrhythmia. Moreover, the disease is often noticed late, which makes proper treatment even more difficult. Therefore, the Dutch Heart Foundation funded the RACE V consortium. Afterwards, the Dutch Heart Foundation guided an exploration to form a national consortium as a follow-up around this theme. This led to the EmbRACE consortium, which is a national network of six university medical centers, UMC Groningen, Maastricht UMC+, UMC Utrecht, Amsterdam UMC and LUMC and Erasmus MC, and hospitals in Arnhem and Eindhoven. The Dutch Heart Foundation funds the research.

The focus of this project is to develop a novel home-based exergaming system aimed at enhancing resistance to falls among individuals post-stroke. Preventing falls and fall-related injuries, minimizes healthcare utilization and societal costs and supports stroke survivors in maintaining independence in daily life. The Research The HEROES system is designed to target balance perturbations and improve stepping responses. It utilizes action observation and motor imagery techniques to personalize training for individuals with stroke. Stroke survivors will undergo a single training session in a rehabilitation center to practice recovering from real balance perturbations before using HEROES at home. The effectiveness of the HEROES-system will be assessed through a proof-of-principle randomized controlled trial (RCT) involving 60 stroke survivors, evaluating its impact on fall resistance and balance enhancement post-stroke. The approach of involving stroke survivors sets HEROES clearly apart from the currently available home-based exergames, which uses ‘healthy’ people and lack the required personalization of different post-stroke individuals. 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.
