Abstract
Background and aimsGuidelines recommend that high-risk patients with atherosclerotic cardiovascular disease (ASCVD) be treated with maximally tolerated statins to lower low-density lipoprotein cholesterol (LDL-C) levels and reduce the risk of major adverse cardiovascular events. In patients whose LDL-C remains elevated, non-statin adjunct therapies, including ezetimibe (EZE), bempedoic acid (BA), and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are recommended. MethodsThe impact of BA and EZE in a fixed-dose combination (FDC) on LDL-C goal attainment was evaluated using a simulation model developed for a United States cohort of high-risk adults with ASCVD. Treatment was simulated for 73,056 patients not at goal (LDL-C >70 mg/dL), comparing BA + EZE (FDC), EZE only, and no oral adjunct therapy (NOAT). The addition of PCSK9 inibitors was assumed after 1 year in patients not at LDL-C goal. Treatment efficacy was estimated from clinical trials. Patient-level outcomes were predicted over a 10-year horizon accounting for treatment discontinuation and general mortality. ResultsBaseline mean age of the cohort was 67 years, most were White (79%) and male (56%). A majority had established coronary artery disease (75%), 48% had diabetes, and mean LDL-C was 103.0 mg/dL. After 1 year, 79% of patients achieved LDL-C goal (mean, 61.1 mg/dL) with BA + EZE (FDC) compared to 58% and 42% with EZE (71.7 mg/dL) and NOAT (78.4 mg/dL), respectively. ConclusionsThis simulation shows that adding BA + EZE (FDC) to maximally tolerated statins would result in more patients achieving LDL-C goal than adding EZE alone or NOAT.
