The fourth edition of IACR guidelines builds on the previous iteration by applying a more systematic and fully documented methodology, synthesising current international cardiac rehabilitation (CR) guidelines and providing recommendations for CR based on the strongest possible evidence.
This resource is intended to provide best practice guidance to assist CR providers as they support patients transitioning from the acute phase of cardiac disease to long-term management. The medical, physical, and psychosocial aspects of heart disease are comprehensively addressed through a specific set of core components.

The guideline development group (GDG) achieved this by conducting a systematic review of key guidelines published since 2013 and extracting and evaluating recommendations based on their strength and level of evidence. These were compiled into a decision matrix and critically appraised to identify contextually appropriate elements for the Irish healthcare setting. Where existing guidelines lacked detail, additional sources were consulted. Interdisciplinary input was maintained throughout to ensure clinical relevance and breadth of expertise. This approach enabled the GDG to integrate the strengths of multiple guidelines, resulting in a robust and operational framework to support the effective delivery of CR services in Ireland.
Fundamentally, this document provides a detailed, step-by-step guide to the key components of modern CR, outlines how they should be implemented, and defines the standards to be met throughout CR.

Where fully implemented, CR programmes will align with best international standards and guarantee the delivery of high-quality CR.
