American College of Cardiology/American Heart Association EHR Terminology Files

The American College of Cardiology (www.acc.org)/American Heart Association (professional.heart.org) Terminology is a set of terms intended to represent key data elements and definitions for electronic health records (EHRs) created for patients with cardiovascular disorders. The goals of developing these clinical data standards include: to establish a consistent, interoperable, and universal clinical vocabulary as a foundation for both clinical care and clinical research, including clinical trials; to promote the ubiquitous use of EHRs and facilitate the exchange of data across systems through harmonized, standardized definitions of key data elements; to facilitate the further development of clinical registries, quality and performance improvement programs, outcomes evaluations, and clinical research, including the comparison of results within and across these initiatives. ACC/AHA is fully responsible for the content of this standard.

A Task Force on Clinical Data Standards was convened by the American College of Cardiology (ACC) and the American Heart Association (AHA) where they seated a Writing Committee chaired by Jeffrey R. Boris, MD to develop the terminology in collaboration with the American Academy of Pediatrics, the Association of European Paediatric Cardiologists, the Child Health Corporation of America, the Congenital Cardiac Anesthesia Society, the Congenital Heart Surgeons' Society, the International Society for Nomenclature of Paediatric and Congenital Heart Disease, the National Association of Children's Hospitals and Related Institutions, and the Society of Thoracic Surgeons.

The first domain, Pediatric and Congenital Cardiology (PCC), was published as the 2017 AHA/ACC Key Data Elements and Definitions for Ambulatory Electronic Health Records in Pediatric and Congenital Cardiology (Boris JR et al. J Am Coll Cardiol. 2017 Aug 22;70(8):1029-1095). It is one of sixteen domains of mutual interest that have been identified. The other domains are to be comprised of: congenital heart defect nomenclature, adult congenital heart disease, critical care, cardiomyopathy, cardiac transplantation, pulmonary hypertension, congenital cardiac surgery, echocardiography, diagnostic and interventional catheterization, exercise stress testing and physiology, electrophysiology, cardiac magnetic resonance imaging, fetal physiology, perfusion, and cardiac anesthesia.

The ACC/AHA Cardiovascular and Noncardiovascular Complications of COVID-19 Terminology, is terminology used in support of the American College of Cardiology (ACC)/American Heart Association's (AHA) efforts to collect key data elements pertaining to cardiovascular and noncardiovascular complications of COVID-19 (from 2022 AHA/ACC Key Data Elements and Definitions for Cardiovascular and Noncardiovascular Complications of COVID-19: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Data Standards. Bozkurt B et al. Circ Cardiovasc Qual Outcomes. 2022; 15:e000111).

Also included are the following additional files:

Changes.txt (A text file of changes between the most recent and the current version of the PCC terminology. For each change record, the Changes.txt contains a complete row of tab delimited data with the same data elements as described above. An "A" will precede any new concept additions, a "C" will precede any modification to existing concepts, and a "D" will precede any concepts that have been deleted.)
Version.txt (A text file that contains the version of NCI Thesaurus that corresponds to the current spreadsheet data. The database is reconciled the last Monday of every month. The files will be posted during the following two weeks. The version appears as YR.MOweek. An example is 20.02d which corresponds to the year 2020, the month of February, and the "d" refers to the fourth Monday of the month.)
