Abstract
Background and aims
Cardiovascular outcomes trials have demonstrated that lowering low-density lipoprotein cholesterol (LDL-C) reduces the risk for future cardiovascular events. We assessed the potential cardiovascular benefits of bempedoic acid through a simulation study in patients with atherosclerotic cardiovascular disease (ASCVD) and elevated LDL-C.
Methods
The validated SMART prediction model was used to estimate the baseline 10-year risk of three-point major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke) in patients with ASCVD who were enrolled in four Phase 3, randomized, placebo-controlled bempedoic acid studies. The predicted change in 10-year cardiovascular risk associated with bempedoic acid was estimated for each patient based on the Cholesterol Treatment Trialists' model. Data were analyzed in two cohorts: Cohort 1 included mostly patients treated with moderate-high intensity statins, and Cohort 2 included patients who were intolerant of more than low-intensity statin.
Results
A total of 2884 patients were included in Cohort 1 and 226 in Cohort 2. Weighted average baseline 10-year cardiovascular event risk was 26.1% and 31.6% for Cohorts 1 and 2, respectively. The least squares mean percent difference (95% confidence interval (CI) of the predicted absolute change in 10-year cardiovascular event risk with bempedoic acid was -3.3% (-3.7% to -2.9%) for patients in Cohort 1 and -6.0% (-7.7% to -4.3%) for patients in Cohort 2 compared with placebo (p < 0.0001 for both).
Conclusions
Among patients with ASCVD who could potentially benefit from additional LDL-C lowering, our simulation predicted a lower absolute cardiovascular event risk after initiating bempedoic acid as compared with placebo.
