EMBRACE

2023

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.

Delta Plan Heart Failure

2023

Heart failure is a severe and chronic condition were the heart is unable to pump blood around the body properly, due to a structural and/or functional abnormality of the heart. It has many different causes, with the most common being hypertension and coronary artery disease. Heart failure is an unpredictable condition with sudden exacerbations of the disease, hospitalization, and will ultimately lead to death. Proper (and early) treatment may improve the symptoms of health failure and may lead to a relatively longer and better quality of life.
The origin
On the cardiovascular disease research agenda, as drawn up at the initiative of the Dutch Heart Foundation in 2014 and revised in 2020, the themes “Earlier recognition of cardiovascular disease” and “Heart failure” have been placed on the agenda. The DCVA also announced the Delta Plan Heart Failure in the 2022 annual plan.
This resulted in the Delta Plan Heart Failure, which is initiated and financed by the Hartstichting, the Netherlands Heart Institute, and the Dutch Cardiovascular Alliance. In this national project, healthcare professionals, researchers, and patients have joined forces and will focus on the entire continuum of the disease from prevention to palliative care.
The research
We expect that burden of disease can largely be reduced by addressing the following key-points:

Increasing public awareness of heart failure
Early detection of heart failure
Stimulating the collaboration among all (different) disciplines within the field of health failure
Initiation of research consortia for innovative treatment and management of heart failure patients
Furthermore, this project will not only focus on positively influencing survival but also on optimizing the patient’s quality of life and will pursue a strategic and operational approach.
