WASHINGTON, March 23, 2020 — The 2020 AHA/ACC Key Data Elements and Definitions for Coronary Q1 Revascularization published in the Journal of the American College of Cardiology and Circulation on Monday, March 23, 2020, at 2:00 p.m. ET.

The American College of Cardiology and American Heart Association recognize the importance of the use of clinical data standards for patient management, assessment of outcomes, and conduct of research, and the importance of defining the processes and outcomes of clinical care, whether in randomized trials, observational studies, registries, or quality improvement initiatives. This document publishes consensus-based key data elements and definitions for databases capturing information about coronary revascularization.

Heart disease is the leading cause of death in the United States, and coronary artery disease is the most common type of heart disease. The annual estimated cost of heart disease in the United States is $218 billion, and a substantial portion of this expense is related to the cost of hospitalizations for interventional cardiology and cardiac surgery. Large databases, such as the Society of Thoracic Surgeons (STS) National Database, the ACC National Cardiovascular Data Registry (NCDR), and the Get With The Guidelines–Coronary Artery Disease database, contain a wealth of information on cardiac surgical procedures, invasive cardiac procedures, and selected clinical conditions but do not contain information about healthcare economics (charges and costs) and only limited data on longitudinal outcome. To address these limitations, the STS and NCDR metrics must be linked to other sources of data such as Centers for Medicare and Medicaid Services data. The success of this type of research, using linked data sets, depends on the harmonization of clinical data standards and definitions across databases.
