Industry relationships among authors of U.S. Clinical Practice Guidelines in cardiology from 2014 to 2020.

Clinical practice guidelines and Scientific statements are influential publications that define the standard of care for many diseases.

We identified guidelines published between 2014 and 2020 by the American Heart Association (AHA) and the American College of Cardiology (ACC) in order to assess the payment status of CPG authors using the Open Payment Program (OPP) database.
