Insights
Bempedoic acid significantly lowered cardiovascular events compared to ezetimibe in patients on moderate-intensity statins. This suggests bempedoic acid may offer greater atherosclerotic cardiovascular disease risk reduction than previously thought.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Residual atherosclerotic cardiovascular disease (ASCVD) risk persists despite moderate-intensity statin therapy, necessitating additional non-statin treatments.
- Ezetimibe is a common first-line oral non-statin, while bempedoic acid is an alternative, especially for statin-intolerant patients.
- Real-world cardiovascular outcomes data for bempedoic acid combined with moderate-intensity statins are limited.
Purpose of the Study:
- To compare real-world cardiovascular outcomes between bempedoic acid and ezetimibe when used as add-on therapy to moderate-intensity statins.
- To evaluate the effectiveness of these non-statin therapies in reducing major adverse cardiovascular events.
Main Methods:
- A retrospective cohort study utilizing the TriNetX global federated health research network.
- Inclusion criteria: adults (≥18 years) on moderate-intensity statin therapy with add-on bempedoic acid or ezetimibe.
- Primary outcome: composite of stroke, myocardial infarction, ischemic heart disease, new-onset heart failure, or peripheral artery disease. Risk ratios (RRs) were calculated.
Main Results:
- The study included 6706 matched patients (3353 per group).
- Bempedoic acid was associated with a significantly lower risk of the composite outcome versus ezetimibe (16.7% vs 22.8%; RR: 0.73).
- Individual cardiovascular endpoints favored bempedoic acid, although ezetimibe achieved greater low-density lipoprotein cholesterol (LDL-C) reduction.
Conclusions:
- Bempedoic acid demonstrated significantly lower cardiovascular event rates compared to ezetimibe in adults on moderate-intensity statins.
- Despite lower LDL-C reduction, bempedoic acid showed a greater potential for ASCVD risk reduction.
- Findings support considering bempedoic acid for enhanced ASCVD risk management beyond current clinical guideline recommendations.
Background:
Residual atherosclerotic cardiovascular disease (ASCVD) risk remains common among adults treated with moderate-intensity statins, necessitating nonstatin therapy. Ezetimibe is the preferred first-line oral nonstatin therapy. However, bempedoic acid is emerging as an alternative, particularly in patients with statin intolerance. Cardiovascular outcomes with bempedoic acid among patients receiving moderate-intensity statins in routine care are not well-established.
Objective:
To compare cardiovascular outcomes associated with bempedoic acid vs ezetimibe when added to background moderate-intensity statin therapy in the real world.
Methods:
This retrospective cohort study used the TriNetX global federated health research network. Adults aged 18 years or older receiving moderate-intensity statin therapy with add-on bempedoic acid or ezetimibe were included. The primary outcome was a composite of stroke, myocardial infarction, ischemic heart disease, new-onset heart failure, or peripheral artery disease. Risk ratios (RRs) with 95% CIs were calculated.
Results:
After matching, 6706 patients were included (n = 3353 per cohort). Bempedoic acid was associated with a significantly lower risk of the composite outcome compared with ezetimibe (16.7% vs 22.8%; RR: 0.73; 95% CI: 0.63-0.84). All individual cardiovascular endpoints favored bempedoic acid. Low-density lipoprotein cholesterol (LDL-C) reduction was greater with ezetimibe.
Conclusion:
Among adults on moderate-intensity statins, bempedoic acid was associated with significantly lower cardiovascular event rates compared with ezetimibe, despite smaller LDL-C reductions. These findings complement Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen (CLEAR) Outcomes and suggest greater ASCVD risk-reducing potential for bempedoic acid than currently reflected in clinical guidelines.
