The use of AI in electrocardiograms could reduce hospitalisations for heart failure by 40%

The consortium of the FAITHFUL innovation project, led by the Spanish start-up Idoven, with the support of EIT Health, has just launched the development of a technological solution that aims to prevent 4 out of 10 hospitalisations for heart failure in Europe. TIC Salut Social Foundation is one of the entities that is part of this new consortium, funded with 1.7 million euros until the end of 2025.

The project is based on the use of advanced algorithms and artificial intelligence applied to electrocardiograms (ECGs) to detect early signs of heart failure in Primary Care settings. By providing a disease score from ECG results, this ground-breaking approach provides clinicians at healthcare centres with crucial information to make informed decisions on patient treatment and management, with earlier referral to a cardiologist. The project will recruit more than 2,500 European patients with risk factors associated with heart failure to demonstrate the reliability of its algorithm in the early detection of heart failure decompensation.

Heart failure ranks first in terms of hospital admissions

Heart failure affects 770,000 people in Spain1 and more than 15 million in Europe2. It is also the leading cause of hospitalisation in people over 65 years of age and of unscheduled hospital readmissions3. Studies suggest that hospitalisations for HF will increase by 50% in the next 25 years4, mainly due to the progressive ageing of the population and a growing prevalence of cardiovascular risk factors such as hypertension, diabetes, hypercholesterolemia, and obesity, among others.

Dr Manuel Marina Breysse, cardiologist, and CEO of Idoven, explains: “This project has the potential to transform the way heart failure is diagnosed and managed radically.” Heart failure represents a huge cost to healthcare systems because it is difficult to diagnose before it manifests itself. “In this way, we want to contribute to the sustainability of the healthcare system, improving the health and quality of life of the population,” adds Dr. Marina Breysse.

Under the leadership of Idoven, the FAITHFUL consortium is formed by prominent health organizations, including AstraZeneca Spain, the Servicio Madrileño de Salud (SERMAS), the Fundación para la Investigación Biomédica del Hospital 12 de Octubre, the Fundación para la Investigación Biomédica del Hospital Gregorio Marañón, the Fundación para la Investigación e Innovación Biosanitaria de Atención Primaria, the Institut Català de la Salut, Karolinska Institute, Region Stockholm, MADoPA – Centre Expert en Technologies et Services pour le Maintien en Autonomie à Domicile des Personnes Âgées, and the Estonian Health Insurance Fund. Additionally, FAITHFUL counts on the collaboration of several key external partners, including the Fundación Instituto de Investigación Marqués de Valdecilla (Idival), the Fundación del Ilustre Colegio Oficial de Médicos de Madrid (Fundación ICOMEM), and TIC Salut Social Foundation.

About the role of TIC Salut Social Foundation

TIC Salut Social Foundation will provide its experience in understanding the complexities of public healthcare systems in integrating new technologies and processes into established healthcare frameworks. Thus, its focus will be on assisting in the development of realistic scalability plans, carefully assessing the feasibility of scaling up solutions while considering our systemic view.

Moreover, it will serve as a strategic partner in the FAITHFUL project, forging close collaborations with stakeholders, including the Catalan Ministry of Health. This partnership will ensure alignment with broader healthcare objectives and regulatory frameworks, enhancing the project’s efficacy and sustainability.
