RESUMO
OBJECTIVE: Novel lipid-lowering therapies are being introduced. Few studies exist of the real-world effectiveness of adenosine-tri-phosphate citrate lyase inhibition with bempedoic acid. METHODS: This study audited bempedoic acid therapy in 216 consecutive patients from three hospital centres - a university hospital (n = 77) and two district general hospitals (n = 106 and 33). Cardiovascular disease (CVD) risk factors, prescription qualification criteria, efficacy and adverse effects were assessed. RESULTS: The population was aged 65.9 ± 11.0 years, 42% were male, 25% had type 2 diabetes, and 31% had familial hypercholesterolaemia. CVD was present in 19% and multibed vascular disease in 8%. Statin intolerance was reported in 92%. Bempedoic acid reduced total cholesterol by 1.58 ± 1.44 mmol/L (20%), LDL-C by 1.37 ± 1.31 mmol/L (27%), triglycerides by 0.22 mmol/L (2%) with an 0.06 mmol/L (1%) increase in HDL-C after 22 ± 9 months follow-up. An LDL-C <2.5 mmol/L was achieved in 40% and <2 mmol/L in 20%. Efficacy (r2 = .33) was predicted by baseline LDL-C (ß = .54; p <.001). No significant changes were seen in transaminases, creatinine, creatine kinase, urate or HbA1c. Treatment was discontinued by 33% of patients and occurred due to myalgia (43%), lack of efficacy (16%) and gastrointestinal adverse effects (15%). No cases of gout were observed. In a logistic regression only the number of previous drug classes not tolerated (ß = 1.60; p = .009) was a contributing factor to discontinuation. CONCLUSION: This audit suggests that bempedoic acid therapy is effective but that adverse effects and discontinuation are common. This suggests nocebo effects might be generalizable to all lipid-lowering drug therapies in susceptible individuals.
