ESC Quality Indicators for Post-myocardial infarction Care: Transition and Chronic Coronary Syndrome Phases. Developed in collaboration with the European Association of Preventive Cardiology of the ESC.

Aims We aimed to develop the European Society of Cardiology (ESC) quality indicators (QIs) for myocardial infarction (MI), from one year after hospital discharge, corresponding to transition to the chronic coronary syndromes phase.Methods And Results We collaborated with the European Association of Preventive Cardiology (EAPC) and developed QIs for the long-term management of patients following MI. We applied the ESC methodology for QI development by: (i) determining key domains of post-MI care; (ii) developing candidate QIs by performing a systematic review of the literature, and (iii) selecting the final set of QIs using a modified Delphi approach. In total, 18 QIs were identified across seven domains of care including (1) structural framework, (2) risk assessment and follow-up, (3) pharmacological management, (4) rehabilitation, behavioral and preventive interventions, (5) coronary revascularization, (6) clinical outcomes and (7) patient-reported outcomes.Conclusion We present the ESC QIs from one year after hospitalization for MI, to standardize and address gaps in care for this high-risk group. These QIs are supported by evidence from contemporary literature, endorsed by expert consensus and aligned with the 2024 ESC guidelines on the management of chronic coronary syndromes.Measures to evaluate and improve the long-term management of patients following a heart attack are needed. In this paper, we identified key aspects of care that can help clinicians, decision-makers and patients improve the quality of care, from one year after a heart attack onwards, and help address inequalities and variations in clinical practice.
