Consensus document on diagnosis and management of familial hypercholesterolemia from the Italian Society for the Study of Atherosclerosis (SISA). Nutr Metab Cardiovasc Dis 2024; 34:1819-1836. [PMID: 38871496 DOI: 10.1016/j.numecd.2024.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 04/04/2024] [Accepted: 05/03/2024] [Indexed: 06/15/2024]
Abstract
AIMS Familial Hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism that causes an increased risk of premature atherosclerotic cardiovascular disease (ASCVD). Although early diagnosis and treatment of FH can significantly improve the cardiovascular prognosis, this disorder is underdiagnosed and undertreated. For these reasons the Italian Society for the Study of Atherosclerosis (SISA) assembled a Consensus Panel with the task to provide guidelines for FH diagnosis and treatment. DATA SYNTHESIS Our guidelines include: i) an overview of the genetic complexity of FH and the role of candidate genes involved in LDL metabolism; ii) the prevalence of FH in the population; iii) the clinical criteria adopted for the diagnosis of FH; iv) the screening for ASCVD and the role of cardiovascular imaging techniques; v) the role of molecular diagnosis in establishing the genetic bases of the disorder; vi) the current therapeutic options in both heterozygous and homozygous FH. Treatment strategies and targets are currently based on low-density lipoprotein cholesterol (LDL-C) levels, as the prognosis of FH largely depends on the magnitude of LDL-C reduction achieved by lipid-lowering therapies. Statins with or without ezetimibe are the mainstay of treatment. Addition of novel medications like PCSK9 inhibitors, ANGPTL3 inhibitors or lomitapide in homozygous FH results in a further reduction of LDL-C levels. LDL apheresis is indicated in FH patients with inadequate response to cholesterol-lowering therapies. CONCLUSION FH is a common, treatable genetic disorder and, although our understanding of this disease has improved, many challenges still remain with regard to its identification and management.

Abstract
Non-statin drugs find utility in the management of dyslipidaemia in mixed dyslipidaemia, patients with statin intolerance, and when guidelines directed low-density lipoprotein cholesterol (LDL-C) target cannot be achieved despite maximally tolerated statin. The most definite indication of fenofibrate monotherapy is fasting serum triglyceride >500 mg/dl to reduce the risk of acute pancreatitis It offers a modest reduction in cardiovascular events. The statin-ezetimibe combination is commonly used for lipid lowering particularly after ACS. Fish oils reduce serum triglycerides by about 25 %. EPA (and not DHA) seems to have cardioprotective effects. Despite cardiovascular outcome benefits, bile-exchange resins have limited use due to poor tolerance. Bempedoic acid added to maximally tolerated statin therapy is approved to lower LDL-C in adults with primary hypercholesterolemia or mixed dyslipidaemias, HeFH, in patients with ASCVD who require additional lowering of LDL-C, and in patients who are statin-intolerant. Inclisiran is a long-acting double-stranded small interfering RNA (siRNA) that inhibits the transcription of PCSK-9 leading to a decrease in PCSK9 generation in hepatocytes and an increase in LDL receptor expression in the liver cell membrane leading to about 50 % reduction in serum LDL-C levels. Lomitapide lowers plasma levels of all ApoB-containing lipoproteins, including VLDL, LDL, and chylomicrons by inhibiting the enzyme microsomal triglyceride transfer protein (MTP) and approved for the treatment of adult patients with homozygous familial hypercholesterolemia (HoFH). Close monitoring for hepatotoxicity is required. Mipomersen is a single-stranded synthetic antisense oligonucleotide (ASO) that affects the production and secretion of apoB-containing lipoproteins with demonstrated efficacy in both homozygous and heterozygous FH patients. It is approved for restricted use due to risk of hepatotoxicity. Pelacarsen is an antisense oligonucleotide that reduces the production of apo(a) in the liver.

Abstract
Familial hypercholesterolemia (FH) is an autosomal dominant inheritable disease with severe disorders of lipid metabolism. It is mainly marked by increasing levels of plasma total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), xanthoma, corneal arch, and early-onset coronary heart disease (CHD). The prevalence of FH is high, and it is dangerous and clinically underdiagnosed. The clinical treatment for FH includes both pharmacological and non-pharmacological treatment, of which non-pharmacological treatment mainly includes therapeutic lifestyle change and dietary therapy, LDL apheresis, liver transplantation and gene therapy. In recent years, many novel drugs have been developed to treat FH more effectively. In addition, the continuous maturity of non-pharmacological treatment techniques has also brought more hope for the treatment of FH. This paper analyzes the pathogenic mechanism and the progress in clinical treatment of FH. Furthermore, it also summarizes the mechanism and structure-activity relationship of FH therapeutic drugs that have been marketed. In a word, this article provides a reference value for the research and development of FH therapeutic drugs.

Abstract
AIMS Refractory hypercholesterolemia (RH), caused primarily by the loss-of-function mutation of LDL receptor (LDLR) gene seen in HoFH and HeFH patients, remains a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Statin and ezetimibe combination therapy lower circulating LDL by 30% in HoFH patients. PCSK9 mAB, being an LDLR-dependent therapy, is not effective in HoFH, but lowers LDL by 25% in HeFH patients. A maximum reduction of 50% was noted in HoFH patients treated with ANGPTL3 mAB, which was not enough to achieve therapeutic goal of LDL. Therefore, new approaches are warranted to offer hopes to individuals intolerant to higher dose statins and not able to achieve recommended LDL level. DATA SYNTHESIS New approaches to lower LDL include gene therapy and gene editing. AAV-based gene therapy has shown encouraging results in animal models. Using CRISPR/Cas9-mediated genome/base editing, gain of function and loss of function have been successfully done in animal models. Recent progress in the refinement of genome/base editing has overcome the issues of off-target mutagenesis with ∼1% mutagenesis in case of PCSK9 and almost no off-target mutagenesis in inactivating ANGPTL3 in animal models showing 50% reduction in cholesterol. Current approaches using CRISPR-Cas9 genome/base editing targeting LDLR-dependent and LDLR-independent pathways are underway. CONCLUSIONS The new information on gain of LDLR function and inactivation of ANGPTL3 together with developments in genome/base editing technology to overcome off-target insertion and deletion mutagenesis offer hope to refractory hypercholesterolemic individuals who are at a higher risk of developing ASCVD.

Abstract
Familial hypercholesterolemia (FH) is the most common, but poorly diagnosed autosomal-dominant genetic disease which increases the cardio-vascular risk. AIM To evaluate the experience of FH registry conducted in Karelia Republic. METHODS FH registry in Karelia is existing from 2004, it includes 350 patients with heterozygous FH (110 with definite FH), the mean age is 48 ± 2.3 years. The genetic study was performed in 102 patients (29.1%). RESULT The creation of the registry has contributed to the active identification of FH, and now the estimated frequency of FH occurrence in Karelia may be 1:300, in patients with cardiovascular disease 1:10. We also analyzed genetic features of FH in our republic and found that the LDL-C level, above which the probability of LDL receptor mutation increases in Karelia, is 6.5 mmol/L. We analyzed risk factors of ischemic heart disease and the prognosis in FH. CONCLUSION The creation and maintenance of a registry is an effective way of organizing timely diagnosis and adequate treatment of FH patients.

Abstract
BACKGROUND AND AIMS Familial hypercholesterolemia (FH) is a common autosomal dominant disorder that can result in premature atherosclerotic cardiovascular disease (ASCVD). Limited data are available worldwide about the prevalence and management of FH. Here, we aimed to estimate the prevalence and management of patients with FH in five Arabian Gulf countries (Saudi Arabia, Oman, United Arab Emirates, Kuwait, and Bahrain). METHODS The multicentre, multinational Gulf FH registry included adults (≥18 years old) recruited from outpatient clinics in 14 tertiary-care centres across five Arabian Gulf countries over the last five years. The Gulf FH registry had four phases: 1- screening, 2- classification based on the Dutch Lipid Clinic Network, 3- genetic testing, and 4- follow-up. RESULTS Among 34,366 screened patient records, 3713 patients had suspected FH (mean age: 49±15 years; 52% women) and 306 patients had definite or probable FH. Thus, the estimated FH prevalence was 0.9% (1:112). Treatments included high-intensity statin therapy (34%), ezetimibe (10%), and proprotein convertase subtilisin/kexin type 9 inhibitors (0.4%). Targets for low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol were achieved by 12% and 30%, respectively, of patients at high ASCVD risk, and by 3% and 6%, respectively, of patients at very high ASCVD risk (p <0.001; for both comparisons). CONCLUSIONS This snap-shot study was the first to show the high estimated prevalence of FH in the Arabian Gulf region (about 3-fold the estimated prevalence worldwide), and is a "call-to-action" for further confirmation in future population studies. The small proportions of patients that achieved target LDL-C values implied that health care policies need to implement nation-wide screening, raise FH awareness, and improve management strategies for FH.

Abstract
Aim: To determine the prevalence, genetic characteristics, current management and outcomes of familial hypercholesterolaemia (FH) in the Gulf region. Methods: Adult (18-70 years) FH patients were recruited from 9 hospitals and centres across 5 Arabian Gulf countries. The study was divided into 4 phases and included patients from 3 different categories. In phase 1, suspected FH patients (category 1) were collected according to the lipid profile and clinical data obtained through hospital record systems. In phase 2, patients from category 2 (patients with a previous clinical diagnosis of FH) and category 1 were stratified into definitive, probable and possible FH according to the Dutch Lipid Clinic Network criteria. In phase 3, 500 patients with definitive and probable FH from categories 1 and 2 will undergo genetic testing for 4 common FH genes. In phase 4, these 500 patients with another 100 patients from category 3 (patients with previous genetic diagnosis of FH) will be followed for 1 year to evaluate clinical management and cardiovascular outcomes. The Gulf FH cohort was screened from a total of 34,366 patients attending out-patient clinics. Results: The final Gulf FH cohort consisted of 3,317 patients (mean age: 47±12 years, 54% females). The number of patients with definitive FH is 203. In this initial phase of the study, the prevalence of (probable and definite) FH is 1/232. Conclusion: The prevalence of FH in the adult population of the Arabian Gulf region is high. The Gulf FH registry, a first-of-a-kind multi-national study in the Middle East region, will help in improving underdiagnosis and undertreatment of FH in the region.

Abstract
The American College of Cardiology and American Heart Association (ACC/AHA) guidelines identified four statin benefit groups on the basis of atherosclerotic cardiovascular disease risk reduction and proposed statin therapy by evidence-based intensity. Although these guidelines used randomized controlled trials with hard outcomes as exclusive evidence for its recommendations, a limited number of studies conducted in Asian countries makes its application of treatment strategy, intensity, and statin doses uncertain in these population. This prospective, multicenter study aimed to evaluate the efficacy of rosuvastatin 10 mg in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines in the Korean population. The primary endpoint was percentage reduction in low-density lipoprotein (LDL) cholesterol. Secondary endpoints were percentage reduction in other lipids and achievement of ≥50% reduction in LDL cholesterol. Rosuvastatin 10 mg lowered LDL cholesterol by 61.4 mg/dL, a 44.9% decrease from baseline after eight weeks. Reduction of LDL cholesterol ≥50% was achieved in 46.3% of patients. Rosuvastatin 10 mg was generally well tolerated. In the Korean population, rosuvastatin 10 mg was favorable and tolerant in lowering LDL cholesterol in the four statin benefit groups requiring high- or moderate-intensity statin therapy according to the ACC/AHA guidelines.

Abstract
The reduction of plasma apolipoprotein B (apoB) containing lipoproteins has long been pursued as the main modifiable risk factor for the development of cardiovascular disease (CVD). This has led to an intense search for strategies aiming at reducing plasma apoB-lipoproteins, culminating in reduction of overall CV risk. Despite 3 decades of progress, CVD remains the leading cause of morbidity and mortality worldwide and, as such, new therapeutic targets are still warranted. Clinical and preclinical research has moved forward from the original concept, under which some lipids must be accumulated and other removed to achieve the ideal condition in disease prevention, into the concept that mechanisms that orchestrate lipid movement between lipoproteins, cells and organelles is equally involved in CVD. As such, this review scrutinizes potentially atherogenic changes in lipid trafficking and assesses the molecular mechanisms behind it. New developments in risk assessment and new targets for the mitigation of residual CVD risk are also addressed.

Abstract
Coronary heart disease (CHD) is the leading cause of mortality worldwide and high low-density lipoprotein (LDL) cholesterol levels have been shown to be key in the pathogenesis of this condition. Lipid control has therefore been the subject of decades of research and has led to many large and robust randomized controlled trials, as well as the highest grossing drug of all time—Lipitor (atorvastatin). Statin therapy has long been indicated for secondary and more recently primary prevention. However, despite the large-scale use of statins, CHD prevalence remains high, and some patients do not respond to statin therapy. There has been a large push to find and test alternative lipid-lowering agents, these include fibrates, cholesterol absorption inhibitors, and proprotein convertase subtilisin/kexin type 9 (PCSK-9) inhibitors. It is the aim of this review to assess the literature surrounding each of these groups of drugs.

Abstract
Atherosclerosis often begins in childhood or adolescence. Post-mortem studies in children have shown the presence of coronary atheroma, and there are hereditary conditions associated with hyperlipidaemia in childhood which lead to premature cardiovascular disease. Detection of hyperlipidaemia early in life can be crucial in the prevention of premature death from atherosclerosis. The circulating lipoproteins are in a constant state of flux, with passage of apolipoproteins and lipids between the various particles. Genetic variants of apolipoproteins can cause both hypercholesterolaemia and hypertriglyceridaemia. Elevated concentrations of lipoprotein(a) predispose to coronary artery disease. Another important molecule in lipid metabolism, proprotein convertase subtilisin/kexin type 9 (PCSK9), plays a crucial role in the removal of low-density lipoprotein (LDL) receptors. Reference intervals for the various lipid subfractions are now available for children, and there are guidelines regarding when to take action regarding paediatric hyperlipidaemia. The most important genetic condition in children which may lead to premature death from coronary heart disease is familial hypercholesterolaemia (FH). FH is best diagnosed and treated early in life. Most cases are due to defects in the LDL receptor. Pharmacotherapy for FH usually involves the statin group of drugs, although newer medications are now available, especially for the treatment of homozygous FH. Statin therapy has been demonstrated to be successful in preventing cardiac events in FH. Secondary dyslipidaemia in childhood can be associated with numerous diseases including diabetes, lifestyle disorders such as obesity, and drugs. Treatment of the underlying condition usually resolves the hyperlipidaemia.

Abstract
AIM We aimed to compare the effects of fixed-dose combinations of ezetimibe plus rosuvastatin to rosuvastatin alone in patients with primary hypercholesterolemia, including a subgroup analysis of patients with diabetes mellitus (DM) or metabolic syndrome (MetS). METHOD This multicenter eight-week randomized double-blind phase III study evaluated the safety and efficacy of fixed-dose combinations of ezetimibe 10 mg plus rosuvastatin, compared with rosuvastatin alone in patients with primary hypercholesterolemia. Four hundred and seven patients with primary hypercholesterolemia who required lipid-lowering treatment according to the ATP III guideline were randomized to one of the following six treatments for 8 weeks: fixed-dose combinations with ezetimibe 10 mg daily plus rosuvastatin (5, 10, or 20 mg daily) or rosuvastatin alone (5, 10, or 20 mg daily). RESULTS Fixed-dose combination of ezetimibe plus rosuvastatin significantly reduced LDL cholesterol, total cholesterol, and triglyceride levels compared with rosuvastatin alone. Depending on the rosuvastatin dose, these fixed-dose combinations of ezetimibe plus rosuvastatin provided LDL cholesterol, total cholesterol, and triglyceride reductions of 56%-63%, 37%-43%, and 19%-24%, respectively. Moreover, the effect of combination treatment on cholesterol levels was more pronounced in patients with DM or MetS than in non-DM or non-MetS patients, respectively, whereas the effect of rosuvastatin alone did not differ between DM vs non-DM or MetS vs non-MetS patients. CONCLUSION Fixed-dose combinations of ezetimibe and rosuvastatin provided significantly superior efficacy to rosuvastatin alone in lowering LDL cholesterol, total cholesterol, and triglyceride levels. Moreover, the reduction rate was greater in patients with DM or MetS.

Abstract
Emergence of hyperlipidemia in urban population of India and the world at large is very high and accounts to several fatal diseases. This condition is known to manifest elevated levels of lipids and/or lipoproteins. Serious limitations like inadequate solubility, less absorption, less bioavailability, ineffectiveness in lowering of cholesterol levels, patient incompliance and so on are noticed with majority of anti-hyperlipidemic drugs and dosage forms, which are used conventionally. To overcome these shortcomings, building technology platforms for development of appropriate dosage forms is the need of the hour. These efforts are required to maximize patient acceptability while maintaining safety, efficacy, accessibility and affordability. Hyperlipidemia, its types, etiology, pathophysiology and conventional dosage forms are discussed here. The current approaches and novel developments which illustrate controlled drug release and sustained therapeutic effect along with site specific and target oriented drug delivery with better patient compliance are also reviewed critically. Despite the incentives provided by the efforts of formulation scientists, there is still a need for implementation of pharmaceutical technologies that enable to combat limitations of anti-hyperlipidemic drugs and conventional dosage forms associated with it. The present review emphasize on applications of novel drug delivery systems in pharmacotherapy of anti-hyperlipidemic drugs demonstrating the advantages and disadvantages.

Abstract
OBJECTIVES To evaluate the lipid-altering efficacy and safety of ezetimibe monotherapy in young children with heterozygous familial hypercholesterolemia (HeFH) or nonfamilial hypercholesterolemia (nonFH). STUDY DESIGN One hundred thirty-eight children 6-10 years of age with diagnosed HeFH or clinically important nonFH (low-density lipoprotein cholesterol [LDL-C] ≥ 160 mg/dL [4.1 mmol/L]) were enrolled into a multicenter, 12-week, randomized, double-blind, placebo-controlled study. Following screening/drug washout and a 5-week single-blind placebo-run-in with diet stabilization, subjects were randomized 2:1 to daily ezetimibe 10 mg (n = 93) or placebo (n = 45) for 12 weeks. Lipid-altering efficacy and safety were assessed in all treated patients. RESULTS Overall, mean age was 8.3 years, 57% were girls, 80% were white, mean baseline LDL-C was 228 mg/dL (5.9 mmol/L), and 91% had HeFH. After 12 weeks, ezetimibe significantly reduced LDL-C by 27% after adjustment for placebo (P < .001) and produced significant reductions in total cholesterol (21%), nonhigh-density lipoprotein cholesterol (26%), and apolipoprotein B (20%) (P < .001 for all). LDL-C lowering response in sex, race, baseline lipids, and HeFH/nonFH subgroups was generally consistent with overall study results. Ezetimibe was well tolerated, with a safety profile similar to studies in older children, adolescents, and adults. CONCLUSIONS Ezetimibe monotherapy produced clinically relevant reductions in LDL-C and other key lipid variables in young children with primary HeFH or clinically important nonFH, with a favorable safety/tolerability profile.

Abstract
BACKGROUND This study evaluated the effectiveness of long-term intensive lipid-lowering therapy in children and adolescents with familial hypercholesterolaemia. METHODS The charts of 89 children and adolescents with heterozygous familial hypercholesterolaemia among ∼1000 patients treated from 1974 to 2008 were reviewed. Familial hypercholesterolaemia was defined as low-density lipoprotein cholesterol level >90th percentile in individuals with a history of familial hypercholesterolaemia. RESULTS Of the 89 patients, 51% were male; the mean age at diagnosis was 8 ± 4 years, and the mean follow-up was 13 ± 8 years. Baseline and most recent low-density lipoprotein cholesterol levels (mg/dl) under treatment were 250 ± 50 and 142 ± 49, respectively, reduced 43% from baseline (p < 0.0001). At the most recent visit, 39 patients received statin monotherapy, mainly atorvastatin or rosuvastatin, and 50 (56%) patients received combination therapy, mainly vytorin or rosuvastain/ezetimibe, 15 patients were >30 years of age, and none developed symptomatic cardiovascular disease or needed revascularisation. CONCLUSIONS Long-term statin-based therapy can reduce low-density lipoprotein cholesterol levels in most children and adolescents with heterozygous familial hypercholesterolaemia and decrease cardiovascular risk significantly.

Abstract
BACKGROUND Fibrates have been prescribed for decades as 'broad-spectrum' lipid modifying agents that can improve plasma levels of triglycerides, high-density lipoprotein cholesterol, and triglyceride-rich lipoproteins, including very low- and intermediate-density lipoproteins. Fibrates are variably effective in lowering low-density cholesterol levels. Available fibrates include gemfibrozil, fenofibrate, bezafibrate, etiofibrate and ciprofobrate; only fenofibrate and gemfibrozil are available in Australia. METHODS Members of the Queensland Lipid Group provided consensus grades of recommendations for the clinical use of fibrates based on PubMed searches, product information, and personal clinical experience. RESULTS Fibrates are well tolerated, and the combination of fenofibrate with statins appears to be safer than gemfibrozil, particularly with regard to adverse effects on muscle. Evidence has been provided recently for the efficacy of fenofibrate in reducing microvascular complications in diabetic patients, including progression of retinopathy, progression of microalbuminuria and nephropathy, development of sensory neuropathy, and leg amputation. Macrovascular benefits appear to be confined to those with reduced high-density lipoprotein cholesterol and/or increased triglyceride levels, and the relationship of microvascular benefits of fenofibrate to baseline lipid levels is variable and requires further assessment. CONCLUSIONS Indications for fibrate therapy may be extended in the future to include protection from both macro- and micro-vascular disease, particularly in diabetic patients and patients with residual dyslipidaemia in spite of statin therapy. We provide recommendations on the use of fibrates in clinical practice to highlight these potential indications.

Abstract
The lowering of low-density lipoprotein cholesterol (LDL-C) is the primary target of therapy in the primary and secondary prevention of cardiovascular events. Although statin therapy is the mainstay for LDL-C lowering, a significant percentage of patients prescribed these agents either do not achieve targets with statin therapy alone or have partial or complete intolerance to them. For such patients, the use of adjuvant therapy capable of providing incremental LDL-C reduction is advised. One such agent is ezetimibe, a cholesterol absorption inhibitor that targets uptake at the jejunal enterocyte brush border. Its primary target of action is the cholesterol transport protein Nieman Pick C1 like 1 protein. Ezetimibe is an effective LDL-C lowering agent and is safe and well tolerated. In response to significant controversy surrounding the use and therapeutic effectiveness of this drug, we provide an update on the biochemical mechanism of action for ezetimibe, its safety and efficacy, as well as the results of recent randomized studies that support its use in a variety of clinical scenarios.

Abstract
Familial hypercholesterolaemia (FH) is an autosomal dominant disorder characterised by increased plasma concentrations of low density lipoprotein (LDL) cholesterol leading to atherosclerosis and premature coronary heart disease (CHD) and death. The clinical diagnosis of FH is based on a personal and family history, physical examination findings and LDL-cholesterol concentrations. FH is primarily caused by mutations in the LDL-receptor gene (LDLR), and less frequently by mutations in genes for APOB and the more recently identified PCSK9. Lifestyle modification and pharmacotherapy can delay or prevent the onset of CHD in FH. It is estimated that only 20% of cases have been diagnosed in Australia and that the majority are inadequately treated. Screening options for FH include population screening (of children or adults), targeted screening of patients with premature CHD and their relatives, or opportunistic screening such as flagging laboratory lipid reports. Cascade screening, a form of targeted screening, is an ethically acceptable, cost-effective strategy for the identification of FH. However, for screening to be successful, medical practitioners need to be aware of the signs and diagnosis of FH and the benefits of early treatment.

Abstract
Patients suffering from familial hypercholesterolemia (FH) are characterized by increased plasma levels of low-density lipoprotein cholesterol (LDL-C) levels and are at increased risk for premature cardiovascular disease (CVD). Current guidelines emphasize the need to aggressively lower LDL-C in FH patients, and statins are the cornerstone in the current regimen. However, additional therapies are eagerly awaited, especially for those patients not tolerating statin therapy or not reaching the goals for therapy. Our understanding of LDL metabolism has improved over the last years and an increasing number of potential novel targets for therapy have been recently identified. Apart from novel targets, we have also been confronted with novel modalities of treatment, such as mRNA antisense therapy. Some of these emerging therapies have proven to be effective in lowering plasma LDL-C levels and are as such expected to have beneficial effects on CVD. Hopefully, they will enrich our armamentarium against the severe dyslipidemia observed in FH patients in the not too distant future.
