Why the study?
Standardized data definitions are essential for quality monitoring and clinical research, but contemporary pan-European data standards for ACS and PCI were lacking.
The development of standardized data definitions for ACS and PCI by the EuroHeart project will facilitate international observational research, quality improvement, and registry-based randomized trials.
Adoption of EuroHeart mandatory variables supports harmonized ACS and PCI quality metrics across Europe; extends infrastructure for multinational registry research and trials.
Standardized data definitions are essential for monitoring and benchmarking the quality of care and patient outcomes in observational studies and randomized controlled trials. There are no contemporary pan-European data standards for the acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart) project of the European Society of Cardiology (ESC) aimed to develop such data standards for ACS and PCI. Following a systematic review of the literature on ACS and PCI data standards and evaluation of contemporary ACS and PCI registries, we undertook a modified Delphi process involving clinical and registry experts from 11 European countries, as well as representatives from relevant ESC Associations, including the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and Acute CardioVascular Care (ACVC). This resulted in final sets of 68 and 84 'mandatory' variables and several catalogues of optional variables for ACS and PCI, respectively. Data definitions were provided for these variables, which have been programmed as the basis for continuous registration of individual patient data in the online EuroHeart IT platform. By means of a structured process and the interaction with major stakeholders, internationally harmonized data standards for ACS and PCI have been developed. In the context of the EuroHeart project, this will facilitate country-level quality of care improvement, international observational research, registry-based randomized trials, and post-marketing surveillance of devices and pharmacotherapies.

Batra et al. (2022) studied Acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). EuroHeart standardized data variables and definitions was evaluated on Final sets of mandatory and optional variables for ACS and PCI. The EuroHeart project developed 68 mandatory variables for acute coronary syndrome and 84 mandatory variables for percutaneous coronary intervention to facilitate country-level quality improvement and international research.
