AHA/ACC Key Data Elements and Definitions for Coronary Revascularization Published

April 27, 2020—The American College of Cardiology and American Heart Association's (ACC/AHA) Task Force on Clinical Data Standards have produced the “2020 AHA/ACC Key Data Elements and Definitions for Coronary Revascularization.” The document was published by Gregory J. Dehmer, MD, et al of the Writing Committee to Develop Clinical Data Standards for Coronary Revascularization in Journal of the American College of Cardiology (2020;75;1975–2088).

Biykem Bozkurt, MD, who serves as Chair, ACC/AHA Task Force on Clinical Data Standards, explained the aims of the document in its preamble.

According to the preamble, “The ACC and AHA 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.”

The preamble outlines the specific goals of clinical data standards as the following:

  1. To establish a consistent, interoperable, and universal clinical vocabulary as a foundation for clinical care and clinical research
  2. To facilitate the exchange of data across systems through harmonized, standardized definitions of key data elements
  3. To facilitate the further development of clinical registries, quality and performance improvement programs, outcomes evaluations, public reporting, and clinical research, including the comparison of results within and across these initiatives

The Data Elements and Definitions encompass:

  • History and risk factors
  • Clinical presentations
  • Laboratory tests
  • Noninvasive tests
  • Invasive testing
  • Surgical revascularization
  • Coronary artery nomenclature
  • Percutaneous coronary intervention
  • Other outcomes

Anticipated use of these clinical data standards includes, but is not limited to, the following settings:

  1. Cardiovascular procedure reports related to coronary revascularization: (a) stress testing reports; (b) nuclear perfusion study reports; (c) cardiac magnetic resonance, CT, and positron emission tomography reports; (d) echocardiogram reports; (e) cardiac catheterization reports; (f) percutaneous intervention reports; (g) cardiac surgery reports; (h) revascularization summary for the patient’s records
  2. Electronic health record systems that store and retrieve data related to coronary revascularization
  3. Cardiovascular clinical studies related to coronary revascularization
  4. Registries that collect, analyze, store, and report information on coronary revascularization
  5. Digital health information technology interoperability
  6. Public reporting programs
  7. United States medical schools, for incorporation into medical teaching
