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.

Clinical staff in hospital wards traditionally collect vital signs periodically to assess a patient's cardiorespiratory status, often with intervals of 6 to 10 hours. This method, known as spot-checking, has limitations due to its infrequent nature and dependence on contact sensors, which can be uncomfortable for patients, particularly during sleep. The Focus Recent advancements demonstrate that vital signs like heart rate, respiration rate, blood oxygen saturation, and temperature can be monitored remotely using camera-based methods, which are less invasive compared to contact sensors. This innovation could significantly enhance patient comfort by enabling continuous monitoring without the need for frequent interventions by clinical staff. Continuous monitoring also allows for trend analysis of vital signs, offering a comprehensive assessment of a patient's cardiorespiratory condition. Additionally, camera-based methods enable video context analysis, such as detecting patient movements or identifying pain through facial expression analysis. This project explores the use of continuous video monitoring as an unobtrusive method to predict and monitor patient deterioration or adverse events. The Research Initially, the feasibility and reliability of camera-based continuous monitoring will be evaluated using data from consenting patients in the ICU at Catharina Hospital in Eindhoven and healthy volunteers. Subsequently, robust technologies will be developed to automatically detect signs of patient deterioration by generating automated early warning scores based on measured vital signs. Throughout the project, feedback from clinical staff and patient experiences will inform the design and implementation of camera-based technologies and early warning systems. 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.
