A PAN-EUROPEAN FLAGSHIP INITIATIVE

Trustworthy AISafer hearts

Building the European ecosystem for AI adoption in CVD and related NCD care

ABOUT CHAIN

We create the conditions for trustworthy cardiovascular AI to move from validation to real-world deployment at scale across Europe

OUR MISSION

From connected data to AI that works in practice

CHAIN brings together data, AI and real-world implementation to accelerate safe and equitable adoption across European healthcare systems

Connected data

CHAIN will reduce the fragmentation that currently limits the reuse of cardiovascular health data by improving interoperability, harmonisation, metadata and data quality across participating organisations. In line with the European Health Data Space (EHDS), this will support consistent data authorised use through shared standards and governance approaches.

Key outputs:

EHDS-aligned data standards, phenotype library, CV metadata catalogue and federated infrastructure

Discoverable AI

CHAIN will make AI solutions easier to find, understand and assess by combining a searchable repository aligned with FAIR principles (Findable, Accessible, Interoperable, Reusable) with AI Passports and evaluation services.

Key outputs:

FAIR AI repository, AI Passports and evaluation services

Real-world implementation

CHAIN will test selected AI solutions in six real-world use cases across different clinical settings and populations, generating evidence on performance, implementation barriers and transferability. This will help identify what is needed for trustworthy AI solutions to move from validation towards broader adoption in cardiovascular care.

Key outputs:

Six real-world use cases generating evidence for implementation, transfer and scale

ENABLING IMPLEMENTATION

Core components

Clinician working with health data

Federated data foundation

Federated local data nodes and an ESC reference node, supported by a phenotype library, CV metadata catalogue, harmonisation and data quality tools aligned with the EHDS

Cardiac imaging and clinical technology

AI discovery and documentation

FAIR AI repository and AI Passports making evidence on performance, fairness, explainability, validation and regulatory status transparent and accessible

Patient and clinician during a consultation

Evaluation, deployment and regulatory readiness

AI evaluation services, deployment guidelines and integration support, training, regulatory guidance and post-market monitoring frameworks

AI IN CLINICAL PRACTICE

Six real-world use cases

Six complementary use cases will validate and implement mature AI solutions in real healthcare settings, spanning risk prediction, tailored prevention, early detection and diagnostic workflows

Risk prediction
Population cardiovascular risk prediction — illustrative healthcare image
Cardiovascular careClinical expertise

Personalised cardiovascular
risk trajectories

AI uses longitudinal health data to identify high-risk trajectories earlier and support more personalised cardiovascular prevention

Clinical decision support
Guideline-directed clinical decision support — illustrative healthcare image
Cardiovascular careClinical expertise

Turning guidelines into personalised care

AI supports clinicians with guideline-aligned recommendations and translates approved treatment plans into clear, personalised explanations for patients

ECG triage
ECG triage and early detection — illustrative healthcare image
Cardiovascular careClinical expertise

Earlier detection from routine ECGs

AI analyses routine 12-lead ECGs to flag actionable patterns and improve referral, monitoring and treatment pathways

Cardiac imaging
Echocardiography and cardiac MRI — illustrative healthcare image
Cardiovascular careClinical expertise

Faster, more consistent echo and CMR

AI automates cardiac measurements and structured reporting to reduce variability and turnaround time, with mandatory human verification

Multimodal risk stratification
Right-ventricular failure — illustrative healthcare image
Cardiovascular careClinical expertise

Earlier detection of right-ventricular failure

AI combines imaging, ECG and clinical data to detect RV dysfunction earlier and predict deterioration in high-risk patients

Opportunistic screening
Routine chest CT screening — illustrative healthcare image
Cardiovascular careClinical expertise

Cardiovascular insights from routine chest CT

AI extracts cardiovascular biomarkers from existing chest CT scans to identify actionable abnormalities and support preventive follow-up without additional imaging
