Abstract
A group of experts convened by the Spanish Society of Arteriosclerosis (SEA) has been in charge of updating the SEA document on the indications of PCSK9 inhibitors (PCSK9i) in clinical practice that was published in 2016. This update is justified by the fact that the data from clinical trials carried out on a large scale with PCSK9i have shown that in addition to their high potency to lower atherogenic cholesterol, they reduce the risk of atherosclerotic cardiovascular disease, both in patients with stable disease, and with recent disease, and with a high degree of security. This update provides the recommendations and level of evidence for the prescription of iPCSK9 in patients with homozygous and heterozygous familial hypercholesterolemia, with atherosclerotic cardiovascular disease, and in primary prevention in patients with very high cardiovascular risk. These recommendations have been established taking into account the concentration of LDL-C, the clinical situation of the patient, the additional risk factors and the cost-effectiveness of their use.

Abstract
BACKGROUND Patients with prior cardiovascular events are at very high risk of recurrent events and may benefit from low-density lipoprotein cholesterol (LDL-C) lowering beyond that achieved with maximally tolerated statins. OBJECTIVE To assess potential differences between the efficacy and safety of the proprotein convertase subtilisin/kexin type 9 inhibitor, alirocumab, in patients with vs without prior myocardial infarction (MI)/ischemic stroke. METHODS Data (n = 4880) were pooled from nine ODYSSEY phase 3 trials of alirocumab 75/150 mg or 150 mg every 2 weeks, mostly on background statins ± other lipid-lowering therapies. Analyses were performed according to statin status, alirocumab dose, and control (placebo or ezetimibe). RESULTS Baseline LDL-C, non-high-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and apolipoprotein B levels were lower and lipoprotein(a) higher in patients with than without prior MI/ischemic stroke. LDL-C levels were reduced from baseline to week 24 in patients with (51.1%-62.9%) and without (43.6%-58.3%) prior MI/ischemic stroke, with no significant interaction between prior MI/ischemic stroke status and LDL-C-lowering efficacy of alirocumab vs controls. Alirocumab significantly reduced other lipid/lipoproteins (including lipoprotein[a]) similarly in patients with/without MI/ischemic stroke. Week 24 LDL-C goal attainment rates for subgroups with/without prior MI/ischemic stroke on background statins were 74.1%-84.8% and 63.7%-74.7%, respectively. The safety profile of alirocumab was generally similar regardless of prior MI/ischemic stroke status. CONCLUSIONS Alirocumab significantly reduced LDL-C and other atherogenic lipids/lipoproteins in patients with prior MI/ischemic stroke, and the majority of this very high cardiovascular risk population achieved LDL-C goals; efficacy and safety results were similar in patients without prior MI/ischemic stroke.

Abstract
PURPOSE OF REVIEW The 2018 ACC/AHA Multisociety blood cholesterol guidelines provide updated recommendations based on contemporary evidence on the management of serum cholesterol for the prevention of atherosclerotic cardiovascular disease (ASCVD) events. This review discusses clinically important topics in the new guidelines related to secondary ASCVD prevention. RECENT FINDINGS Since the 2013 ACC/AHA blood cholesterol guidelines, several large randomized control trials involving ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (evolocumab and alirocumab) have been published. The trials provided evidence that these non-statin, LDL-cholesterol lowering agents are efficacious in reducing risk for ASCVD events in patients with clinical ASCVD. The 2018 guidelines incorporate these new findings into updated clinical recommendations on therapeutic strategies related to the use of ezetimibe and PCSK9 inhibitors. The guidelines also recommend risk stratification of secondary prevention patients to identify those at very high-risk of ASCVD events as these patients would derive the most absolute risk reduction from the addition of non-statin therapies. While high-intensity statins remain the first-line treatment to prevent recurrent ASCVD events in secondary prevention patients, ezetimibe and PCSK9 inhibitors are evidence-based non-statin agents that can be used when residual on top of maximally tolerated statin therapy in patients deemed to be at very-high risk of recurrent ASCVD events.

Abstract
There is now significant evidence for the benefits of lowering low-density lipoprotein cholesterol (LDL-c) to reduce the risk of atherosclerotic cardiovascular disease (ASCVD). Although statins are the most widely prescribed lipid-lowering therapy that effectively lower LDL-c, especially in combination with ezetimibe, some patients require adjunctive therapy to further lower LDL-c and mitigate attendant risk of ASCVD. The gap can be filled by proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies whose use is currently supported by two recent cardiovascular outcome studies and new treatment guidelines. We provide an overview of extant studies investigating PCSK9 monoclonal antibodies in various patient populations, an update of the guidelines regarding their use and a case-based discussion.

Abstract
The 2013 American College of Cardiology/American Heart Association guideline on the treatment of blood cholesterol was a landmark document guiding health care professionals around the globe on how to administer lipid-lowering therapies. Those guidelines were primarily focused on statin therapy benefit groups. The writing committee found insufficient evidence for specific low-density lipoprotein cholesterol (LDL-C) treatment targets. There have been many important updates in the lipid literature since the publication of that document. Most importantly, clinical trials have provided definitive evidence for the pivotal role of LDL-C in atherogenesis and the improvement in clinical outcomes by means of aggressive LDL-C reduction. Ezetimibe, evolocumab, and alirocumab treatment resulted in substantial reductions in major adverse cardiovascular outcomes. These data encourage a discussion on whether LDL-C targets are warranted in primary and/or secondary prevention, and if so, how low should those targets be. In order to answer such questions, the costs and safety of such therapies, as well as the safety of very low levels of LDL-C need to be addressed. This review discusses the relationship between LDL-C lowering and cardiovascular risk reduction, the efficacy, safety, and cost-effectiveness of high-intensity lipid-lowering therapies, and the recommendations from the most recent lipid guidelines.

Abstract
Coronary artery disease (CAD) is one of the leading causes of mortality. High circulating levels of low-density lipoprotein (LDL) in the blood are associated with cardiovascular mortality, whether through an etiological role or through its association with the progression of CAD per se. Randomized clinical trials have shown that, when LDL levels are reduced, cardiovascular risk is also reduced, which reinforces this association. The first major trial involving a hypolipidemic agent of the statin family, the Scandinavian Simvastatin Survival Study (4S), was published in 1994 and found a significant reduction in mortality in patients at high cardiovascular risk. However, even in subsequent studies with different statins, a residual risk persisted, and this seems not to have changed over time; it is speculated that this risk may be due to statin intolerance. In this scenario, the potential exists for novel hypolipidemic agents to drive a true revolution in the therapy of dyslipidemia. The recent discovery of PCSK9 inhibitors (PCSK9i), a class of hypolipidemic monoclonal antibodies, is extremely promising. PCSK9 inhibition is capable of promoting a mean LDL reduction of up to 60%, with potential for very significant clinical repercussions, as every 38 mg/dL reduction in LDL appears to be associated with a 22% reduction in cardiovascular risk. This review addresses a brief history of PCSK9i, major trials of these drugs, cardiovascular outcomes, and aspects related to their efficacy and safety. Finally, the molecular mechanisms and possible pleiotropic effects of PCSK9i are also discussed.

Abstract
PURPOSE OF REVIEW The association between elevated plasma levels of lipoprotein (a) [Lp(a)] and atherosclerotic cardiovascular disease (ASCVD) has been discussed for many years. Recent genetic findings have confirmed that elevated Lp(a) similar to elevated LDL-cholesterol (LDL-C) might be causally related to premature ASCVD. Lp(a) is relatively refractory to lifestyle interventions. The results of studies with statins and their possible effect on Lp(a) are conflicting. Specific Lp(a) apheresis is used as a treatment against background statin therapy and can decrease Lp(a). The purpose of this review is to discuss whether new drugs which decrease Lp(a) can prevent ASCVD and decrease ASCVD mortality when applied in addition to statins. RECENT FINDINGS Some new LDL-C-lowering drugs such as mipomersen and lomitapide decrease elevated Lp(a) in addition to statins but they have some unpleasant adverse effects. Recently, an antisense oligonucleotide against apo(a), AKCEA-APO(a)Rx, has been shown to selectively decrease Lp(a). The most recent advance in LDL-C lowering are PCSK9 inhibitors. Alirocumab and evolocumab do not only significantly reduce LDL-C on top of maximally tolerated statin therapy and prevent ASCVD events, but also further decrease Lp(a). There is no data to indicate whether mipomersen, lomitapide, or IONIS-APO(a)-LRx decrease ASCVD events and mortality. Conclusive evidence is still lacking as to whether the treatment with PCSK9 inhibitors against background statin therapy actually additionally reduces ASCVD risk due to the lowering of Lp(a) or simply due to lowering LDL-C to levels much lower than high-intensity statin treatment as monotherapy. Ongoing trials will probably provide an answer to these questions.

Abstract
The recent development of monoclonal antibodies targeted to proprotein convertase subtilisin/kexin type 9 (PCSK9), e.g., PCSK9 inhibitors has revolutionized the landscape of lipid management. Many clinical trials assessing this class have demonstrated remarkable and consistent reductions in low-density lipoprotein-cholesterol. Moreover, the GLAGOV trial demonstrated the efficacy of evolocumab, when added to statin therapy, in reducing the progression of atherosclerosis measured by serial intravascular ultrasound, with the first suggestion of continued benefit down to LDL-C levels of 0.5 mmol/L (20 mg/dL). This trial was followed by the FOURIER Cardiovascular Outcomes trial in more than 27,000 patients with stable atherosclerotic cardiovascular disease (ASCVD) where evolocumab reduced the primary endpoint of atherosclerotic events by 15%, without significant safety differences between treatment groups. Furthermore, subgroup analyses suggested greater benefits seen in those with longer exposure to evolocumab recent acute coronary syndrome, multiple myocardial infarctions, multivessel coronary artery disease, peripheral arterial disease, as well as the subgroup who achieved very low low-density lipoprotein-cholesterol levels of below 0.3 mmol/L (10 mg/dL). Moreover, the EBBINGHAUS substudy demonstrated no differences in objectively measured cognitive function between treatment groups. The SPIRE 2 trial evaluating bococizumab in high-risk patients with baseline LDL-C ≥2.6 mmol/L (100 mg/dL) demonstrated significant atherosclerotic risk reduction, but the trial and further development of the drug was prematurely discontinued due to substantial attenuation of the LDL-C effect over time due to the development of neutralizing antibodies. Finally, the ODYSSEY Cardiovascular Outcomes trial testing alirocumab in subjects with recent (<1 year) acute coronary syndrome demonstrated a 15% relative risk reduction in the primary composite outcome, as well as a significant reduction in total mortality. Greater benefits were noted in those whose LDL-C at baseline was 2.6 mmol/L (100 mg/dL) or greater. These trials collectively demonstrate the added efficacy of PCSK9 inhibitors over moderate and high-intensity statin therapy for unprecedented low-density lipoprotein-cholesterol reduction and incremental ASCVD risk reduction.

Abstract
BACKGROUND The ODYSSEY Outcomes (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) trial included participants with a recent acute coronary syndrome. Compared with participants receiving statins alone, those receiving a statin plus alirocumab had lower rates of a composite outcome including myocardial infarction (MI), stroke, and death. OBJECTIVE To determine the cost-effectiveness of alirocumab in these circumstances. DESIGN Decision analysis using the Cardiovascular Disease Policy Model. DATA SOURCES Data sources representative of the United States combined with data from the ODYSSEY Outcomes trial. TARGET POPULATION U.S. adults with a recent first MI and a baseline low-density lipoprotein cholesterol level of 1.81 mmol/L (70 mg/dL) or greater. TIME HORIZON Lifetime. PERSPECTIVE U.S. health system. INTERVENTION Alirocumab or ezetimibe added to statin therapy. OUTCOME MEASURES Incremental cost-effectiveness ratio in 2018 U.S. dollars per quality-adjusted life-year (QALY) gained. RESULTS OF BASE-CASE ANALYSIS Compared with a statin alone, the addition of ezetimibe cost $81 000 (95% uncertainty interval [UI], $51 000 to $215 000) per QALY. Compared with a statin alone, the addition of alirocumab cost $308 000 (UI, $197 000 to $678 000) per QALY. Compared with the combination of statin and ezetimibe, replacing ezetimibe with alirocumab cost $997 000 (UI, $254 000 to dominated) per QALY. RESULTS OF SENSITIVITY ANALYSIS The price of alirocumab would have to decrease from its original cost of $14 560 to $1974 annually to be cost-effective relative to ezetimibe. LIMITATION Effectiveness estimates were based on a single randomized trial with a median follow-up of 2.8 years and should not be extrapolated to patients with stable coronary heart disease. CONCLUSION The price of alirocumab would have to be reduced considerably to be cost-effective. Because substantial reductions already have occurred, we believe that timely, independent cost-effectiveness analyses can inform clinical and policy discussions of new drugs as they enter the market.

Abstract
AbstractProprotein convertase subtilisin/kexin type 9 (PCSK9) is a hepatic enzyme that regulates the low-density lipoprotein cholesterol (LDL-c) receptor and thus circulating LDL-c levels. With overwhelming evidence now supporting the reduction in LDL-c to lower the risk of cardiovascular disease, PCSK9 inhibitors represent an important therapeutic target, particularly in high-risk populations. Here, we summarise and update the science of PCSK9, including its discovery and the development of various inhibitors, including the now approved monoclonal antibodies. In addition, we summarise the clinical applications of PCSK9 inhibitors in a range of patient populations, as well as the major randomised controlled trials investigating their use in coronary prevention.

Abstract
AIMS Individuals with both diabetes mellitus (DM) and atherosclerotic cardiovascular disease (ASCVD) are at very high risk of cardiovascular events. This post-hoc analysis evaluated efficacy and safety of the PCSK9 inhibitor alirocumab among 984 individuals with DM and ASCVD pooled from 9 ODYSSEY Phase 3 trials. MATERIALS AND METHODS Changes in low-density lipoprotein cholesterol (LDL-C) and other lipids from baseline to Week 24 were analysed (intention-to-treat) in four pools by alirocumab dosage (150 mg every 2 weeks [150] or 75 mg with possible increase to 150 mg every 2 weeks [75/150]), control (placebo/ezetimibe) and background statin usage (yes/no). RESULTS At Week 24, LDL-C changes from baseline in pools with background statins were -61.5% with alirocumab 150 (vs -1.0% with placebo), -46.4% with alirocumab 75/150 (vs +6.3% with placebo) and -48.7% with alirocumab 75/150 (vs -20.6% with ezetimibe), and -54.9% with alirocumab 75/150 (vs +4.0% with ezetimibe) without background statins. A greater proportion of alirocumab recipients achieved LDL-C < 70 and < 55 mg/dL at Week 24 vs controls. Alirocumab also resulted in significant reductions in non-high-density lipoprotein cholesterol, apolipoprotein B and lipoprotein(a) vs controls. Alirocumab did not appear to affect glycaemia over 78-104 weeks. Overall safety was similar between treatment groups, with a higher injection-site reaction frequency (mostly mild) with alirocumab. CONCLUSION Alirocumab significantly reduced LDL-C and other atherogenic lipid parameters, and was generally well tolerated in individuals with DM and ASCVD.

Abstract
Inflammatory changes are responsible for maintenance of the atherosclerotic process and may underlie some of the most feared vascular complications. Among the multiple mechanisms of inflammation, the arterial deposition of lipids and particularly of cholesterol crystals is the one responsible for the activation of inflammasome NLRP3, followed by the rise of circulating markers, mainly C-reactive protein (CRP). Elevation of lipoproteins, LDL but also VLDL and remnants, associates with increased inflammatory changes and coronary risk. Lipid lowering medications can reduce cholesterolemia and CRP: patients with elevations of both are at greatest cardiovascular (CV) risk and receive maximum benefit from therapy. Evaluation of the major drug series indicates that statins exert the largest LDL and CRP reduction, accompanied by reduced CV events. Other drugs, mainly active on the triglyceride/HDL axis, for example, PPAR agonists, may improve CRP and the lipid pattern, especially in patients with metabolic syndrome. PCSK9 antagonists, the newest most potent medications, do not induce significant changes in inflammatory markers, but patients with the highest baseline CRP levels show the best CV risk reduction. Parallel evaluation of lipids and inflammatory changes clearly indicates a significant link, both guiding to patients at highest risk, and to the best pharmacological approach. Key messages Lipid lowering agents with "pleiotropic" effects provide a more effective approach to CV prevention In CANTOS study, patients achieving on-treatment hsCRP concentrations ≤2 mg/L had a higher benefit in terms of reduction in major CV events The anti-inflammatory activity of PCSK9 antagonists appears to be of a minimal extent.

Abstract
PURPOSE OF REVIEW There has been confusion following the 2013 American College of Cardiology/American Heart Association (ACC/AHA) Lipid guidelines on the role of non-statin medications for cardiovascular prevention. RECENT FINDINGS Several recent large trials have also now shown that lowering LDL with non-statins reduces cardiovascular events. In ASCVD patients on statins, adding ezetimibe or a PCSK9 inhibitor led to reductions in CV events in the IMPROVE IT, FOURIER, and most recently the ODYSSEY-OUTCOMES trials. Additional novel therapies reducing LDL and other atherogenic lipoproteins are in development during this exciting time in this field. With recent evidence, the 2017 ACC Expert Consensus Decision pathway calls for initial therapy with statins, monitoring LDL levels, and then adding ezetimibe and/or PCSK9 inhibitors to further lower LDL-C to targets based on the patient's risk.
