Statins have improved the potential to prevent cardiovascular disease events and to prolong the lives of patients. Statins, among the most widely used drugs worldwide, reduce the levels of low-density lipoprotein cholesterol (LDL-C) by an average of 30-50%. However, non-adherence to statin therapy, due to statin intolerance, might be as high as 60% after 24 months of treatment and is associated with a 70% increase in the risk of cardiovascular disease events. Statin intolerance can be classified as a complete inability to tolerate any dose of a statin or a partial intolerance with the inability to tolerate the dose necessary to achieve the patient-specific therapeutic objective. Reasons for discontinuation are many, with statin-associated muscle symptoms being cited as the most frequent reason for stopping therapy and the incidence of muscle symptoms increasing with treatment intensity. Considering the causal effect of LDL-C in the atherosclerotic process, clinicians should consider that regardless of the lipid-lowering drugs patients are willing to take, any reduction in LDL-C they achieve will afford them some benefit in reducing cardiovascular risk. Besides statins, the current therapeutic armamentarium offers different strategies to reach LDL-C targets in statin-intolerant patients (i.e. a fixed combination between a lower dose of statin plus ezetimibe, bempedoic acid, or proprotein convertase subtilisin/kexin type 9 inhibition)., Competing Interests: Conflict of interest: none declared., (© The Author(s) 2024.

Aims: We performed quality control of lipid-lowering therapy (LLT) in patients with acute coronary syndrome (ACS), with a view to proposing corrective actions., Methods and Results: Using a Define Measure Analysis Improve Control (DMAIC) approach applied to data from the ACS EuroPath IV survey, we measured attainment of two quality indicators (QIs) related to lipid-lowering treatment: (i) prescription of high-intensity statins (or equipotent treatment) before discharge, and (ii) proportion with LDL-cholesterol <55 mg/dL (1.4 mmol/L) during follow-up. A total of 530 European cardiologists responded and provided data for up to 5 patients from their centre, for acute and follow-up phases. Corrective measures are proposed to increase the rate of attainment of both QIs. Attainment of the first QI was measured in 929 acute-phase patients, 99% had LLT prescribed at discharge and 75% of patients fulfilled the first QI. Attainment of the second QI was assessed in 1721 patients with follow-up. The second QI was reached in 31% of patients. The DMAIC approach yielded 10 potential changes in prescription, 3 for the first and 7 for the second QI. The overall strategy is 'Fire to Target', i.e. early intensification of the LLT using statins, ezetimibe, bempedoic acid, and proprotein convertase subtilisin/kexin type-9 inhibitors, and is presented as an algorithm for routine application., Conclusion: Quality control for LLT, based on the ACS EuroPath IV survey, detected 10 potential changes in prescription that could enhance attainment of 2 QIs. Whether the Fire to Target strategy will be adopted and effective needs to be assessed in further steps of the EuroPath Quality programme., Competing Interests: Conflict of interest: F.S. has received research grants from and/or was speaker (with or without lecture fees) on a.o.

Aims: Reduction of low-density lipoprotein cholesterol (LDL-C) decreases cardiovascular mortality and morbidity. Bempedoic acid represents a promising novel lipid-modifying agent for patients who cannot reach guideline recommended LDL-C goals or statin-intolerant patients, but data on safety and cardiovascular outcomes are limited. We therefore aimed to systematically review randomized controlled trials investigating bempedoic acid vs. placebo in patients with hyperlipidaemia., Methods: A systematic search on the databases PubMed, Web of Science, and Embase until 20 March 2023 was performed. All randomized trials comparing bempedoic acid (180 mg daily) with placebo in patients with an indication for lipid-lowering therapy were included. As a primary endpoint, we analysed three-point major adverse cardiovascular events (MACEs) consisting of cardiovascular death, non-fatal myocardial infarction (MI), or non-fatal stroke. The analysis was carried out using the odds ratio (OR) as the outcome measure. Due to the expected heterogeneity across studies, a random-effects model was fitted to the data., Results: Out of 258 manuscripts, 10 manuscripts fulfilled the inclusion criteria. In total, these trials included 18 200 patients (9765 on bempedoic acid, 8435 on placebo). Bempedoic acid significantly reduced MACEs compared with placebo (OR 0.84 [95% confidence interval (CI) 0.76-0.96]; P < 0.001; I2 = 0%). The endpoint reduction was driven by a lower rate of non-fatal MI, whereas bempedoic acid had no significant effect on stroke (OR 0.86 [95% CI 0.69-1.08]; P = 0.20, I2 = 0%) and all-cause mortality (OR 1.19 [95% CI 0.73-1.93]; P = 0.49; I2 = 18%)., Conclusion: Bempedoic acid reduced non-fatal MI in patients with hyperlipidaemia, whereas it had no significant effect on stroke and all-cause mortality., (© The Author(s) 2023.

Patients suffering from acute coronary syndrome (ACS) present a high risk of recurrence and new adverse cardiovascular events after hospital discharge. Elevated plasma LDL-cholesterol (LDL-C) levels have been shown to be a causal factor for the development of coronary heart disease, and robust clinical evidence has documented that LDL-C levels decrease linearly correlates with a reduction in cardiovascular events. Recent studies have also demonstrated the safety and efficacy of an early and significant reduction in LDL-C levels in patients with ACS. In this position paper, Italian Association of Hospital Cardiologists proposes a decision algorithm on early adoption of lipid-lowering strategies at hospital discharge and short-term follow-up of patients with ACS, in the light of the multiple evidence generated in recent years on the treatment of hypercholesterolaemia and the available therapeutic options, considering current reimbursement criteria., (© The Author(s) 2023.

There is still the need to lower LDL-c, although the use of statins, ezetimibe and proprotein convertase subtilisin/kexin type 9. Patients with atherosclerotic cardiovascular disease and/or familial hypercholesterolaemia are treated with statins at maximum tolerated dose, with or without further lipid-lowering drugs, but very often, we can't reach the goal, so bempedoic acid treatment lead to a significant reduction in low-density lipoprotein cholesterol, in different groups of patients, with a favourable safety profile., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

The knowledge that roughly 20% of survivors from an acute coronary syndrome (ACS) event experience a subsequent ischaemic cardiovascular event within 24 months with a 5-year mortality range between 19 and 22% highlights the importance of the lipid-lowering strategies in the secondary prevention after ACS. In this framework, statin treatment significantly improves clinical outcome after ACS. Within this remit, in the present review we critically discuss the use of statin and non-statin lipid-lowering approaches (ezetimibe, evolocumab, alirocumab, inclisiran, and bempedoic acid) in the early management of ACS patients. Relative to this latter aspect, the knowledge that circulating proprotein convertase subtilisin/kexin type 9 (PCSK9) levels are raised during ACS could be a generating hypothesis justifying the use of PCSK9 inhibitors in ACS. Thus, in a field fraught of uncertainty, the main barrier to the widespread prescription of non-statin agents (e.g. PCSK9 inhibitors) relates to their costs when compared with other lipid-lowering agents (e.g. statins and ezetimibe)., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

After experiencing an acute coronary syndrome (ACS), patients are at a high risk of suffering from recurrent ischaemic cardiovascular events, especially in the very early phase. Low density lipoprotein-cholesterol (LDL-C) is causally involved in atherosclerosis and a clear, monotonic relationship between pharmacologic LDL-C lowering and a reduction in cardiovascular events post-ACS has been shown, a concept termed 'the lower, the better'. Current ESC guidelines suggest an LDL-C guided, step-wise initiation and escalation of lipid-lowering therapy (LLT). Observational studies consistently show low rates of guideline-recommended LLT adaptions and concomitant low rates of LDL-C target goal achievement, leaving patients at residual risk, especially in the vulnerable post-ACS phase. In addition to the well-established 'the lower, the better' approach, a 'strike early and strike strong' approach in the early post-ACS phase with upfront initiation of a combined lipid-lowering approach using high-intensity statins and ezetimibe seems reasonable. We discuss the rationale, clinical trial evidence and experience for such an approach and highlight existing knowledge gaps. In addition, the concept of acute initiation of PCSK9 inhibition in the early phase is reviewed. Ultimately, we focus on hurdles and solutions to provide high-quality, evidence-based follow-up care in post-ACS patients., Competing Interests: Conflicts of interest: K.A.K. was a member of the advisory boards at Novartis, Sanofi, and Amgen and received speaker fees from Amgen.

Dyslipidaemias and in particular elevated plasma low-density lipoprotein cholesterol (LDL-C) levels are major risk factors for atherosclerotic cardiovascular disease (ASCVD). Indeed, the more LDL-C is reduced the larger will be the ASCVD risk reduction. Although statins represent the first-line intervention to reduce the atherosclerotic burden driven by raised levels of LDL-C, adherence is not optimal and most patients do not follow guidelines and recommended doses. Thus, to achieve optimal LDL-C goals, especially in very high-risk patients, there is a need for new and safe agents, more tolerable than statins with low risk of myalgia. Thus, the present review will address the most recent clinical trials with bempedoic acid and inclisiran. Bempedoic acid is an oral drug acting at a biochemical step preceding hydroxymethylglutaryl-CoA reductase and not associated with muscular side effects. Inclisiran, the first-in-class small interfering RNA-based approach, has the ability to effectively reduce LDL-C by inhibiting the hepatic synthesis of proprotein convertase subtilisin/kexin type 9, with the advantage of requiring subcutaneous of a single dose on Day 1, Day 90, and every 6 months thereafter., (Published on behalf of the European Society of Cardiology. © The Author(s) 2021.)

Aim: Bempedoic acid is a novel oral drug, which has been increasingly researched to play an important role in the treatment of hypercholesterolemia recently. However, results from original studies were inconsistent and inconclusive. We aimed to conduct a meta-analysis to quantitatively appraise the efficacy and safety of bempedoic acid., Methods: PubMed, Embase, Web of Science and Scopus were searched from inception to 30 January 2020. We included randomized controlled trials that compared the efficacy and safety of bempedoic acid with placebo in patients with hypercholesterolemia. Results from trials were presented as mean differences or odds ratios (ORs) with 95% confidence intervals (CIs) and were pooled by random or fixed effects model. The risk of bias and heterogeneity among trials were also assessed and analyzed., Results: Pooled analysis of 10 eligible trials showed that bempedoic acid treatment resulted in greater lowering of the low-density lipoprotein cholesterol level than the placebo group (mean difference -23.16%, 95% CI -26.92% to -19.04%). We also found that improvements in lipid parameters and biomarkers were still maintained at weeks 24 and 52 from the long-term trials. As for safety, bempedoic acid did not increase the risk of overall adverse events (OR 1.02, 95% CI 0.88 to 1.18). However, the incidence of adverse events leading to discontinuation was higher in the bempedoic acid group (OR 1.44, 95% CI 1.14 to 1.82)., Conclusions: Available evidence from randomized controlled trials suggests that bempedoic acid provides a well-tolerated and effective therapeutic option for lipid lowering in patients with hyperlipidemia., (Published on behalf of the European Society of Cardiology.

Purpose: An update on clinical development of a first-in-class oral medication for adjunctive cholesterol lowering in high-risk patients with persistent elevation of low-density lipoprotein cholesterol (LDL-C) despite statin therapy is reviewed., Summary: Despite the proven efficacy of statin therapy, many patients cannot reach LDL-C goals with statins alone, largely due to inadequate response or intolerance. Nonstatin treatment options to reduce LDL-C include ezetimibe, bile acid sequestrants, and proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors; however their use has been limited by modest clinical benefit or high treatment costs. Novel nonstatin treatments are in development to further address the needs of this population. Bempedoic acid is a first-in-class oral adenosine triphosphate (ATP) citrate lyase inhibitor being evaluated as an additional treatment option for high-risk patients requiring further reduction in LDL-C. Bempedoic acid has been evaluated in multiple phase 2 and phase 3 trials as monotherapy or for use in combination with ezetimibe and/or statin therapy. Treatment with bempedoic acid has been demonstrated to result in significant reductions in LDL-C and several other cardiovascular risk markers without the myalgia associated with statin therapy., Conclusion: Bempedoic acid, used alone or with ezetimibe in a fixed-dose combination formulation, may be an effective alternative to current guideline-recommended nonstatin therapies in patients who do not attain adequate LDL-C lowering with maximally tolerated statin therapy and in statin-intolerant patients at risk for atherosclerotic cardiovascular disease., (© American Society of Health-System Pharmacists 2021.

Despite the demonstrated benefits of statins and injectable biologics, there is a need for new and safe oral agents for addressing classical lipid targets, low-density lipoprotein cholesterol (LDL-C), triglycerides and high-density lipoprotein cholesterol (HDL-C). LDL-C is unquestionably causal in the development of atherogenesis and atherosclerotic cardiovascular disease, but new options are required to address triglyceride-rich lipoproteins and lipoprotein(a). For hypercholesterolaemia, pitavastatin provides a very low dose and potent statin that does not adversely affect glucose metabolism; bempedoic acid acts at a biochemical step preceding hydroxymethylglutaryl-CoA reductase and is not associated with muscular side effects. For hypertriglyceridaemia, pemafibrate displays a unique and selective agonist activity on peroxisomal proliferator activated receptor-α that does not elevate homocysteine or creatinine. Although omega-3 fatty acids supplementation is not effective in secondary prevention, high dose eicosapentaenoic ethyl ester can lead to a remarkable fall in first and recurrent events in high risk patients with hypertriglyceridaemia/low HDL-C. Gemcabene, a dicarboxylic acid regulating apolipoprotein B-100, is effective in reducing both cholesterol and triglycerides. Among cholesteryl ester transfer protein antagonists that elevate HDL-C, only anacetrapib reduces cardiovascular events. Probucol stimulates reverse cholesteryl ester transport, lowers LDL-C stabilizing plaques and may lower incidence of cardiovascular events. These agents, which act through novel mechanisms, afford good and potentially safe treatment choices that may increase adherence and the attainment of therapeutic targets.

Aims: The aim of this study was to evaluate the low-density lipoprotein cholesterol lowering efficacy and safety of a bempedoic acid 180 mg and ezetimibe 10 mg fixed-dose combination in patients with hypercholesterolemia and a high risk of cardiovascular disease receiving maximally tolerated statin therapy., Methods: This phase 3, double-blind clinical trial enrolled adult patients at high risk of cardiovascular disease due to atherosclerotic cardiovascular disease, heterozygous familial hypercholesterolemia, or multiple cardiovascular disease risk factors. Patients were randomly assigned (2:2:2:1) to treatment with the fixed-dose combination, bempedoic acid 180 mg, ezetimibe 10 mg or placebo added to stable background statin therapy for 12 weeks. The primary efficacy endpoint was the percentage change from baseline to week 12 in low-density lipoprotein cholesterol., Results: Among the 301 patients included in the primary analysis, the mean baseline low-density lipoprotein cholesterol level was 3.87 mmol/L (149.8 mg/dL). At week 12, the fixed-dose combination lowered low-density lipoprotein cholesterol (-36.2%) significantly more than placebo (1.8% (placebo-corrected difference -38.0%); P  < 0.001), ezetimibe alone (-23.2%; P  < 0.001) or bempedoic acid alone (-17.2%; P  < 0.001). The fixed-dose combination lowered low-density lipoprotein cholesterol levels similarly across subgroups, including patients receiving high-intensity, other-intensity or no statin therapy. Improvements with the fixed-dose combination were also observed in secondary efficacy endpoints, including high-sensitivity C-reactive protein. In this trial, fixed-dose combination treatment had a generally similar safety profile compared with bempedoic acid, ezetimibe or placebo., Conclusion: The bempedoic acid and ezetimibe fixed-dose combination significantly lowered low-density lipoprotein cholesterol versus placebo or other oral monotherapies and had a favourable safety profile when added to maximally tolerated statin therapy in patients with hypercholesterolemia and high cardiovascular disease risk., Trial Registration: ClinicalTrials.gov identifier: NCT03337308.
