Impact of Guideline-Directed Statin Prescriptions on Cardiovascular Outcomes by Race in a Real-World Primary Prevention Cohort

Year: 2024

Type: article

Abstract: Background: Data on real-world statin prescription in large, private health care networks and impacts on primary prevention of atherosclerotic cardiovascular disease (ASCVD) outcomes across race are scarce. Objectives: The purpose of this study was to investigate the impact of statin prescription on ASCVD outcomes within and across race in a large, nongovernmental health care system. Methods: Statin prescription in Black and White patients without ASCVD was evaluated (2013-2019). Guideline-directed statin intensity was defined as at least "moderate" for intermediate and high-risk patients. Statin prescription at index and ASCVD outcomes at follow-up (myocardial infarction/revascularization, stroke, mortality) were assessed via electronic health care records using International Classification of Diseases-9 and 10 codes. Cox regression models, adjusted for CVD risk factors, were used to calculate HRs for association between statin prescription and incident ASCVD events across race. Results: < 0.05) and all-cause mortality. Intermediate and high-risk Black patients faced a 17% higher risk of mortality compared to White patients. However, the interaction between race and statin prescription was not a significant predictor of incident ASCVD events. Conclusions: Statins remain underprescribed. Although Black patients received proportionally less statin prescription than White patients, this was not associated with higher risk of mortality in Black patients.
