Evaluating a Simple Approach to Identify Adults Meeting the 2018 AHA/ACC Cholesterol Guideline Definition of Very High Risk for Atherosclerotic Cardiovascular Disease

Academic Article

Abstract

  • Purpose: The 2018 American Heart Association/American College of Cardiology (AHA/ACC) cholesterol guideline defines very high atherosclerotic cardiovascular disease (ASCVD) risk as a history of ≥ 2 major ASCVD events or 1 major ASCVD event and multiple high-risk conditions. We tested if a simplified approach, having a history of a major ASCVD event, would identify a high proportion of patients that meet the 2018 AHA/ACC cholesterol guideline criteria for very high risk. Methods: We analyzed data from US adults with health insurance in the MarketScan database who had experienced an acute coronary syndrome in the past year (recent ACS, n = 3626), a myocardial infarction (MI) other than a recent ACS (n = 7572), an ischemic stroke (n = 3551), or symptomatic peripheral artery disease (PAD, n = 5919). Patients were followed from January 1, 2016, through December 31, 2017, for recurrent ASCVD events. Results: Among 16,344 patients with a history of a major ASCVD event, 94.0% met the 2018 AHA/ACC cholesterol guideline definition for very high risk including 92.9%, 96.5%, 93.1%, and 96.2% with a recent ACS, history of MI, history of stroke, and symptomatic PAD, respectively. The incidence of ASCVD events per 1000 person-years was 50.4 (95% CI: 47.6–53.3) among all patients with a history of a major ASCVD event versus 53.1 (95% CI: 50.1–56.1) among patients who met the 2018 AHA/ACC cholesterol guideline definition of very high risk. Conclusion: The vast majority of patients with a recent ACS, history of MI, ischemic stroke, or symptomatic PAD meet the 2018 AHA/ACC cholesterol guideline definition of very high risk.
