Key Points Question What are the trends and sociodemographic variations in the use of secondary prevention treatments for US adults with atherosclerotic cardiovascular disease (ASCVD) in ambulatory settings prior to and following the 2013 American College of Cardiology and American Heart Association guidelines? Findings In this cross-sectional study using nationally representative sample of 11 033 visits for adults with ASCVD, representing a weighted total of 275.3 million visits, statin therapy, aspirin prescription, and lifestyle counseling rates remained low. There was an increase in statin and aspirin prescriptions following the 2013 American College of Cardiology and American Heart Association guidelines, and women and Black patients continued to have lower rates of ASCVD prevention treatments. Meaning These findings suggest low use of secondary cardiovascular prevention strategies among patients with ASCVD and persisting gender and racial disparities.
