Insights
Bempedoic acid (BA) effectively lowers low-density lipoprotein cholesterol (LDL-C) in chronic coronary syndrome (CCS) patients on intensive therapy. Higher baseline LDL-C and diabetes predict greater reduction, with BA showing good tolerability and persistence.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Achieving target low-density lipoprotein cholesterol (LDL-C) levels in chronic coronary syndrome (CCS) patients is difficult despite intensive therapy.
- Bempedoic acid (BA) is an oral option, but real-world data on its effectiveness and patient-specific response factors in Spain are limited.
Purpose of the Study:
- To evaluate the clinical performance and safety of bempedoic acid (BA) in a real-world Spanish cohort of chronic coronary syndrome (CCS) patients.
- To identify patient-level factors associated with LDL-C reduction and target attainment when adding BA to intensive lipid-lowering therapy.
Main Methods:
- Prospective, multicentre study in Cáceres province, Spain, involving 118 CCS patients with LDL-C ≥ 55 mg/dL on stable intensive lipid-lowering therapy.
- Bempedoic acid (BA) 180 mg/day was added to background treatment; lipid parameters, metabolic profile, and safety were assessed over a median of 28 weeks.
- Multivariable analyses were used to determine factors influencing LDL-C reduction and goal achievement.
Main Results:
- Bempedoic acid (BA) reduced LDL-C by 22.8% (mean reduction of 16.36 mg/dL; p < 0.001), achieving target LDL-C < 55 mg/dL in 48.3% of patients.
- Higher baseline LDL-C and the presence of diabetes mellitus were independently associated with greater LDL-C reduction (p=0.001 and p=0.024, respectively).
- BA was well tolerated with high treatment persistence (94.4%), despite a modest increase in uric acid levels and no reported gout events. Over half the patients had elevated baseline lipoprotein(a) levels, indicating significant residual risk.
Conclusions:
- In a real-world Spanish CCS population on intensive therapy, bempedoic acid (BA) provides significant LDL-C reduction and is well-tolerated.
- Patients with higher baseline LDL-C and diabetes mellitus experience greater benefits, supporting personalized treatment approaches.
- BA serves as a valuable intermediate-cost therapeutic option in Spain for patients needing further LDL-C lowering before escalating to more expensive treatments.
Abstract:
Background/Objectives: Achieving guideline-recommended low-density lipoprotein cholesterol (LDL-C) targets in patients with chronic coronary syndrome (CCS) remains challenging despite intensive lipid-lowering therapy. Bempedoic acid (BA) offers an oral therapeutic option, although data on its clinical performance and patient-level determinants of response in real-world Spanish settings are limited. Methods: We conducted a prospective multicentre study across the four healthcare areas of Cáceres province, Spain, including consecutive CCS patients with LDL-C ≥ 55 mg/dL despite stable intensive lipid-lowering therapy. BA 180 mg/day was added to background treatment. Lipid parameters, metabolic profile, and safety outcomes were assessed after a median follow-up of 28 weeks (IQR 23-47). Multivariable analyses were performed to identify factors associated with of LDL-C reduction and target attainment. A total of 118 patients were analyzed for outcomes. Results: A total of 118 patients (mean age 62.4 ± 10.0 years; 79.2% male) were included. BA reduced LDL-C by 22.8% (-16.36 mg/dL; p < 0.001), enabling 48.3% of patients to achieve LDL-C < 55 mg/dL. Higher baseline LDL-C (β = -0.515; p = 0.001) and the presence of diabetes mellitus (B = 13.8 mg/dL; p = 0.024) were independently associated with greater LDL-C reduction. Notably, 56.3% of patients presented with elevated baseline lipoprotein(a) levels (>50 mg/dL), describing a high underlying burden of residual risk. BA was well tolerated, with a modest increase in uric acid levels but no gout events and a high treatment persistence rate (94.4%). Conclusions: In a real-world CCS population receiving intensive lipid-lowering therapy, BA provides clinically meaningful LDL-C reduction with a favorable safety profile in this multicentre cohort from Cáceres province. Patients with higher baseline LDL-C and diabetes derive greater benefit, supporting a more personalized approach to therapy. These findings reinforce the role of BA in Spanish patients as an intermediate step in lipid-lowering strategies before escalation to more costly therapies, addressing the scarcity of local real-world data.
