This 2023 statement updates clinical guidance for homozygous familial hypercholesterolaemia (HoFH), explains the genetic complexity, and provides pragmatic recommendations to address inequities in HoFH care worldwide. Key strengths include updated criteria for the clinical diagnosis of HoFH and the recommendation to prioritize phenotypic features over genotype. Thus, a low-density lipoprotein cholesterol (LDL-C) >10 mmol/L (>400 mg/dL) is suggestive of HoFH and warrants further evaluation. The statement also provides state-of-the art discussion and guidance to clinicians for interpreting the results of genetic testing and for family planning and pregnancy. Therapeutic decisions are based on the LDL-C level. Combination LDL-C-lowering therapy—both pharmacologic intervention and lipoprotein apheresis (LA)—is foundational. Addition of novel, efficacious therapies (i.e. inhibitors of proprotein convertase subtilisin/kexin type 9, followed by evinacumab and/or lomitapide) offers potential to attain LDL-C goal or reduce the need for LA. To improve HoFH care around the world, the statement recommends the creation of national screening programmes, education to improve awareness, and management guidelines that account for the local realities of care, including access to specialist centres, treatments, and cost. This updated statement provides guidance that is crucial to early diagnosis, better care, and improved cardiovascular health for patients with HoFH worldwide.

The causal role of cholesterol in atherosclerosis was established more than 100 years ago. Along with the fact that the higher the cholesterol, the greater the risk of atherosclerotic cardiovascular diseases (ASCVD), many randomized controlled trials (RCT) have shown that lowering LDL cholesterol (LDL-C) is associated with a lower incidence of ASCVD. This impact of lipid-lowering therapies on cardiovascular risk is independent of the drug used, as shown by several meta-analyses and Mendelian randomization studies. Therefore, the concept of using “high-intensity statins” should be changed to “high-intensity lipid-lowering therapies” that go beyond the use of statins. Recent RCTs using non-statin lipid-lowering therapies has provided scientific evidence that the lower the LDL-C, the better in terms of cardiovascular events. Based on these observations, current guidelines recommend achieving very low LDL-C levels in patients with high and very-high cardiovascular risk. To achieve these demanding goals, the physician must use the full spectrum of lipid-lowering therapies, beyond high-intensity, high-dose statins. Oral combination therapies and, when necessary, subcutaneous treatments become the new standard of care for hypercholesterolemia. However, the number of patients achieving LDL-C goals is unacceptably low. This is due in part to insufficient prescription and insufficient treatment. To improve the efficacy of therapy, several strategies have been proposed, step by step, planning therapy and maximizing treatment, based on the needs of the patient. A wider use of lipid-lowering

To evaluate the effectiveness of a cardiovascular polypill including aspirin, ramipril and atorvastatin (CNIC-Polypill), on the incidence of recurrent major cardiovascular events (MACE) and risk factor control in patients with established atherosclerotic cardiovascular disease (ASCVD) vs different pharmacological therapeutic strategies. Retrospective, observational study using data from electronic-health records. Patients were distributed into 4 different cohorts: CNIC-Polypill (case cohort) vs 3 control cohorts: same monocomponents taken separately (Monocomponents), equipotent drugs (Equipotent) and other drugs not included in the previous cohorts (Other therapies). Patients were followed for 2 years or until MACE or death. After propensity score matching, a total of 6456 patients (1614 patients per cohort) were analysed. After 2 years, the risk of recurrent MACE was lower in the CNIC-Polypill cohort compared to the control groups (22%; p = 0.017, 25%; p = 0.002, 27%; p = 0.001, higher in the Monocomponents, Equipotent and Other therapies cohorts, respectively). The incremental proportion of patients who achieved blood pressure (BP) and low-density lipoprotein cholesterol (LDLc) control from baseline was higher in the CNIC-Polypill cohort vs control cohorts (BP controlled patients: +12.5% vs + 6.3%; p

Familial Hypercholesterolemia (FH) is an autosomal dominant disease with an estimated prevalence between 1/200-250. It is under-treated and underdiagnosed. Massive data screening can increase the detection of patients with FH.Study population: Residents in the health coverage area (N: 195.000 inhabitants) and with at least one determination of cholesterol linked to low-density lipoproteins (LDL-C) carried out between January 1, 2010 and December 30, 2019. The highest LDL-C values were selected.nephrotic syndrome, hypothyroidism, Hypothyroid treatment or triglycerides400 mg / dL. Seven algorithms suggestive of Familial Hypercholesterolemia Phenotype (HF-P) were analyzed, selecting the most efficient algorithm that could easily be translated into clinical practice.Based on 6.264.877 assistances and 288.475 patients, after applying the inclusion-exclusion criteria, 504.316 tests were included, corresponding to 106.382 adults and 10.50918 years. The selected algorithm presented a prevalence of 0.62%. 840 patients with HF-P were detected, 55.8% being women and 17818 years old, 9.3% had a history of cardiovascular disease (CVD) and 16.4% had died. 65% of the patients in primary prevention had LDL-C values130 mg / dL and 83% in secondary prevention values70mg / dL. A ratio of 7.64 (1-18) patients with HF-P per analytical requesting physician was obtained.Massive data screening and patient profiling are effective tools and easily applicable in clinical practice for the detection of patients with FH.

Resumen La evaluacion y prevencion del riesgo cardiovascular (RCV) que persiste en los pacientes con dislipidemia a pesar del tratamiento y de haber alcanzado los objetivos especificos de la concentracion plasmatica de colesterol unido a lipoproteinas de baja densidad (c-LDL) es un reto clinico en la actualidad, y sugiere que los biomarcadores lipidicos convencionales resultan insuficientes para una evaluacion precisa del RCV. Mas alla de su contenido lipidico, existen otras caracteristicas propias de las particulas lipoproteicas que determinan su potencial aterogenico y su influencia en el RCV. Sin embargo, dichas caracteristicas adicionales no pueden ser analizadas por las tecnicas utilizadas habitualmente en los laboratorios clinicos. La espectroscopia por resonancia magnetica nuclear (RMN) es una tecnica que permite un analisis detallado de la cantidad, composicion y tamano de las lipoproteinas y proporciona informacion mas detallada del estado del metabolismo lipidico y del RCV en los pacientes dislipemicos. En este articulo un grupo de lipidologos de la Sociedad Espanola de Arteriosclerosis revisa la evidencia existente sobre los mecanismos aterogenicos de las particulas lipoproteicas y describen el fundamento tecnico y la interpretacion de los perfiles lipoproteicos obtenidos mediante RMN, haciendo especial referencia al test disponible en Espana (Liposcale®). Asimismo, se definen los principales perfiles de pacientes en los que dicho analisis aportaria una informacion de mayor interes clinico, los cuales son: a) sospecha de discordancia entre las concentraciones de lipidos y el numero de particulas, situacion frecuente en la diabetes, la obesidad, el sindrome metabolico y la hipertrigliceridemia; b) enfermedad cardiovascular aterotrombotica (ECVA) precoz o recurrente sin factores de RCV que la justifiquen; c) trastornos lipidicos infrecuentes o complejos como las concentraciones extremas de c-HDL, y d) situaciones clinicas en las que las tecnicas analiticas clasicas no pueden aplicarse, como los valores de c-LDL muy bajos.

The assessment and prevention of cardiovascular risk (CVR) that persists in patients with dyslipidaemia despite treatment and achievement of goals specific to the plasma concentration of cholesterol linked to low density (c-LDL) is a clinical challenge today, and suggests that conventional lipid biomarkers are insufficient for an accurate assessment of CVR. Apart from their lipid content, there are other lipid particle characteristics. The results of this study show that there are a number of lipoprotein compounds that determine atherogenic potential and its influence on the CVR. However, such additional characteristics cannot be analysed by the techniques commonly used in clinical laboratories. Nuclear Magnetic Resonance (NMR) is a technique that allows a detailed analysis to be made of the amount, composition, and size of lipoproteins, as well as providing more information about the detailed status of lipid metabolism and CVR in dyslipidaemia patients. In this article a group of lipidologists from the Spanish Society of Arteriosclerosis review the existing evidence on the atherogenic mechanisms of particles and describe the technical basis and interpretation of the profiles lipoproteins obtained by MRI, with special reference to the test available in Spain (Liposcale®). Likewise, the main patient profiles are defined as such that an analysis would provide information of greater clinical interest. These include: a) Suspected mismatch between lipid concentrations and particles, a common situation in diabetes, obesity, metabolic syndrome; b) Early atherothrombotic cardiovascular disease (ECVA) or recurrent without CVR factors to justify it; c) Lipid disorders, rare or complex, such as extreme concentrations of c-HDL, and d) Clinical situations where classical analytical techniques cannot be applied, such as very low c-LDL values.

Background and aims: Homozygous familial hypercholesterolemia (hoFH) may cause life-threatening atherosclerotic cardiovascular disease in childhood. Lipoprotein apheresis (LA) is considered a pivotal treatment option, but data on its efficacy, safety and optimal performance are limited. We therefore established an international registry on the execution and outcomes of LA in HoFH children. Here we report LA policies and short-term outcomes. Methods: We approached centers worldwide, involved in LA in children with hoFH for participation. We collected information on clinical and treatment characteristics on patients aged 0–19 years between November 2016 and November 2018. Results: We included 50 children, treated at 15 sites. Median (IQR) LDL-C levels at diagnosis, on medication and on LA were 19.2 (16.2–22.1), 14.4 (10.8–16.7) mmol/L and 4.6 mmol/L, respectively. Median (IQR) time between diagnosis and start of LA was 2.8 (1.0–4.7) years. Six (12%) patients developed cardiovascular disease during that period. Most children received LA either weekly (43%) or biweekly (37%). Seven (17%) patients reached mean LDL-C levels

Resumen El control actual de la concentracion de colesterol unido a lipoproteinas de baja densidad en el paciente con enfermedad cardiovascular ateroesclerotica es muy escaso y esto se asocia con un aumento del riesgo de que se presenten complicaciones cardiovasculares. Ademas, cuanto mas tarde se logren dichos objetivos, el riesgo sera mayor. Esto se debe principalmente a un uso insuficiente de las terapias hipolipemiantes actualmente disponibles. De hecho, con los tratamientos actuales (estatinas, ezetimiba e inhibidores de la proteina PCSK9), la mayoria de los pacientes en prevencion secundaria deberia lograr los objetivos de control del colesterol unido a lipoproteinas de baja densidad. Por estos motivos, en el presente documento promovido por la Sociedad Espanola de Cardiologia se proponen 3 algoritmos de abordaje sencillos y facilmente aplicables, que abarcan la mayoria de las situaciones clinicas que nos podemos encontrar en los pacientes con cardiopatia isquemica, con el doble objetivo de lograr controlar a la mayoria de los pacientes y hacerlo lo antes posible, ya que el beneficio en prevencion secundaria depende del riesgo y del tiempo.

Assessment of individual cardiovascular risk, distinguishing primary and secondary prevention, would improve the clinical management of the population with familial hypercholesterolemia. We aimed to develop and validate two risk functions to predict incident and recurrent atherosclerotic cardiovascular disease (ASCVD) in a primary care-based population with familial hypercholesterolemia phenotype (FHP), and to compare their predictive capacity with that of the SpAnish Familial hypErcHolEsterolemiA cohoRT (SAFEHEART) risk equation (SAFEHEART-RE).Data from the Catalan primary care system database (SIDIAP) of patients ≥18 years old with FHP in 2006-2013 were used to develop and validate two risk functions to predict incident and recurrent ASCVD. A validation dataset was also used to compare the model predictive capacity to that of SAFEHEART-RE.The new model (SIDIAP-FHP) included age, diabetes, smoking, sex (male), hypertension, and baseline low-density lipoprotein cholesterol in the primary prevention cohort and age, diabetes, smoking, and disease characteristics (progressive, recent, polyvascular, or included myocardial infarction) in the secondary prevention cohort. The models demonstrated a fair fit: C-Statistic: 0.71 (95%CI:0.68-0.75) in primary prevention and 0.65 (95%CI:0.60-0.70) in secondary prevention (higher than that of SAFEHEART-RE: 0.64 [95%CI:0.60-0.68] and 0.55 [95%CI:0.51-0.59], respectively; both p 0.01). The Brier scores obtained with the SIDIAP-FHP score were significantly lower than that obtained with SAFEHEART-RE in both the primary and secondary prevention cohorts.The SIDIAP-FHP score provides accurate ASCVD risk estimates for primary and secondary prevention in the FHP population, with better predictive capacity than that of SAFEHEART-RE in this general population, especially in persons with previous ASCVD.

Objetivo Durante los años 2019 y 2020 se realizaró una serie de reuniones en todo el territorio nacional dirigidas a explicar la metodología y los criterios de elaboración de las recomendaciones sobre la utilización de iPCSK9 publicadas por la Sociedad Española de Arteriosclerosis. Al final de cada una de las reuniones se realizó una encuesta entre los médicos participantes dirigida a describir los requerimientos de prescripción de estos fármacos en las diferentes regiones españolas. Metodología El Proyecto Efecto Mariposa fue desarrollado por un comité científico experto en lipídos. Tras la elaboración de todos los materiales necesarios para llevar a cabo el proyecto, se efectuó una reunión de formadores, impartida por los coordinadores del proyecto, a un total de 17 expertos. Posteriormente, se realizaron 16 talleres regionales con la asistencia de 169 médicos implicados en el manejo de la hipercolesterolemia, los cuales respondieron una encuesta donde se planteaban diferentes cuestiones acerca del uso de los iPCSK9 en su práctica clínica. Resultados Hubo una gran heterogeneidad entre centros en cuanto a los requerimientos y dificultades para la prescripción de iPCSK9. Un 21% de los encuestados indicaron tener dificultades escasas para prescribir iPCSK9 en su hospital, mientras que el 78% encontraba dificultades moderadas o elevadas. Las dificultades procedían en un 18% de aspectos burocrático-administrativos, en un 41% de restricciones en su indicación y en un 38% de ambas. En general, los obstáculos encontrados no dependían del nivel del hospital, de la especialidad ni de la presencia de unidades homologadas de lípidos, si bien la existencia de esta última se asociaba a un mayor número de pacientes tratados con iPCSK9. Los factores asociados con una mayor dificultad en la prescripción fueron: la presencia de una comisión de aprobación, la frecuencia de revisión del tratamiento activo por parte de la farmacia hospitalaria, la cadencia temporal de la prescripción, el perfil de pacientes atendidos y los criterios seguidos por los especialistas para la prescripción. Conclusión Los resultados demuestran importantes diferencias en el tratamiento con iPCSK9 en el contexto de la práctica clínica habitual en España. El análisis de estos resultados permitirá plantear en el futuro actuaciones orientadas a la equidad del acceso a los iPCSK9 a nivel nacional, con el objetivo principal de maximizar su beneficio potencial de acuerdo con el perfil del paciente.

La Sociedad Española de Arteriosclerosis tiene entre sus objetivos contribuir al mayor y mejor conocimiento de la enfermedad vascular, su prevención y su tratamiento. Es de sobra conocido que las enfermedades cardiovasculares son la primera causa de muerte en nuestro país y conllevan además un elevado grado de discapacidad y gasto sanitario. La arteriosclerosis es una enfermedad de causa multifactorial y es por ello que su prevención exige un abordaje global que contemple los distintos factores de riesgo con los que se asocia. Así, este documento resume el nivel actual de conocimientos e incluye recomendaciones y procedimientos a seguir ante el paciente que presenta enfermedad cardiovascular establecida o se encuentra con elevado riesgo vascular. En concreto, este documento revisa los principales síntomas y signos a evaluar durante la visita clínica, los procedimientos de laboratorio y de imagen a solicitar de forma rutinaria o aquellos en situaciones especiales. Igualmente, incluye la estimación del riesgo vascular, los criterios diagnósticos de las distintas entidades que son factores de riesgo cardiovascular, plantea recomendaciones generales y específicas para el tratamiento de los distintos factores de riesgo cardiovascular y sus objetivos finales. Por último, el documento recoge aspectos habitualmente poco referenciados en la literatura como son la organización de una consulta de riesgo vascular. One of the objectives of the Spanish Society of Arteriosclerosis is to contribute to better knowledge of vascular disease, its prevention and treatment. It is well known that cardiovascular diseases are the leading cause of death in our country and entail a high degree of disability and health care costs. Arteriosclerosis is a multifactorial disease and therefore its prevention requires a global approach that takes into account the different risk factors with which it is associated. Therefore, this document summarizes the current level of knowledge and includes recommendations and procedures to be followed in patients with established cardiovascular disease or at high vascular risk. Specifically, this document reviews the main symptoms and signs to be evaluated during the clinical visit, the laboratory and imaging procedures to be routinely requested or requested for those in special situations. It also includes vascular risk estimation, the diagnostic criteria of the different entities that are cardiovascular risk factors, and makes general and specific recommendations for the treatment of the different cardiovascular risk factors and their final objectives. Finally, the document includes aspects that are not usually referenced in the literature, such as the organization of a vascular risk consultation. © 2021 The Authors

Inadequate pregnancy cobalamin status has been associated with adverse offspring metabolic health in Indian and Nepalese studies. Studies of pregnancy cobalamin status and mid-childhood health outside of Asia are scarce.Associations between pregnancy fasting plasma total homocysteine (tHcy), cobalamin status (plasma cobalamin, holotranscobalamin (holoTC), methylmalonic acid (MMA)) and mid-childhood metabolic score (MetSco) ((including fat mass index (zFMI), homeostatic model assessment of insulin resistance (zHOMA-IR) and dyslipidemia (zTG - zHDLc)/2) z-scores)) were investigated in a prospective study of 293 mother-child dyads.Highest versus low-mid pregnancy tHcy tertile was associated with higher mid-childhood MetSco, specifically with higher child zFMI. Stratifying by sex, the maternal tHcy-child MetSco association was limited to boys and confirmed for zFMI and zHOMA-IR. The maternal tHcy-child zFMI association was not mediated by birth weight z-score. First trimester plasma cobalamin was not associated with child outcomes, but other indicators of cobalamin status were. Lowest versus mid-high plasma holoTC tertile was associated with MetSco (specifically zFMI and zHOMA-IR) and highest versus low-mid plasma MMA tertile with higher MetSco and dyslipidemia in boys.Moderately elevated pregnancy tHcy and low cobalamin status were associated with mid-childhood metabolic score in boys. The pregnancy tHcy-child zFMI association was not mediated by birth weight.Fasting plasma total homocysteine (tHcy) during pregnancy and low cobalamin status during early pregnancy are associated with mid-childhood metabolic score and its components in the offspring. These findings were only significant in male offspring. The study provides new evidence that impaired one carbon metabolism during pregnancy is associated with negative health outcomes in the offspring, in a population with low prevalence of cobalamin deficiency. The maternal-offspring associations were observed in the functional markers of cobalamin status (holotranscobalamin and methylmalonic acid) and tHcy, not with plasma cobalamin concentration. Screening for low pregnancy cobalamin status should be considered.

Aims To provide contemporary data on the implementation of European guideline recommendations for lipid-lowering therapies (LLTs) across different settings and populations and how this impacts low-density lipoprotein cholesterol (LDL-C) goal achievement. Methods and results An 18 country, cross-sectional, observational study of patients prescribed LLT for primary or secondary prevention in primary or secondary care across Europe. Between June 2017 and November 2018, data were collected at a single visit, including LLT in the preceding 12 months and most recent LDL-C. Primary outcome was the achievement of risk-based 2016 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) LDL-C goal while receiving stabilized LLT; 2019 goal achievement was also assessed. Overall, 5888 patients (3000 primary and 2888 secondary prevention patients) were enrolled; 54% [95% confidence interval (CI) 52–56] achieved their risk-based 2016 goal and 33% (95% CI 32–35) achieved their risk-based 2019 goal. High-intensity statin monotherapy was used in 20% and 38% of very high-risk primary and secondary prevention patients, respectively. Corresponding 2016 goal attainment was 22% and 45% (17% and 22% for 2019 goals) for very high-risk primary and secondary prevention patients, respectively. Use of moderate–high-intensity statins in combination with ezetimibe (9%), or any LLT with PCSK9 inhibitors (1%), was low; corresponding 2016 and 2019 goal attainment was 53% and 20% (ezetimibe combination), and 67% and 58% (PCSK9i combination). Conclusion Gaps between clinical guidelines and clinical practice for lipid management across Europe persist, which will be exacerbated by the 2019 guidelines. Even with optimized statins, greater utilization of non-statin LLT is likely needed to reduce these gaps for patients at highest risk.

Simple Summary Previously, we have demonstrated that lipid and lipoprotein profiles in breast cancer patients are altered compared to a control showing a new link between triglycerides enriched particles and breast cancer, hence suggesting an active role of lipids and their metabolism in this pathology. In this study, we have demonstrated the importance of tumor microenvironment crosstalk as well as the crucial role of lipid transfer between adipose tissue and cancerous cells. Moreover, we have demonstrated that each breast cancer subtype has their specific lipid signature. Interestingly, drug resistant luminal A cell lines switch this metabolic profile to the triple negative lipid signature. Knowledge of these signatures might help us to understand how these specific lipids are related with drug resistance and how it may clarify new treatments in these cancer patients. Abstract Obesity and adipose tissue have been closely related to a poor cancer prognosis, especially in prostate and breast cancer patients. The ability of transferring lipids from the adipose tissue to the tumor cells is actively linked to tumor progression. However, different types of breast tumor seem to use these lipids in different ways and metabolize them in different pathways. In this study we have tracked by mass spectrometry how palmitic acid from the adipocytes is released to media being later incorporated in different breast cancer cell lines (MDA-MB-231, SKBR3, BT474, MCF-7 and its resistant MCF-7 EPIR and MCF-7 TAXR). We have observed that different lines metabolize the palmitic acid in a different way and use their carbons in the synthesis of different new lipid families. Furthermore, we have observed that the lipid synthesis pattern varied according to the cell line. Surprisingly, the metabolic pattern of the resistant cells was more related to the TNBC cell line compared to their sensitive cell line MCF-7. These results allow us to determine a specific lipid pattern in different cell lines that later might be used in breast cancer diagnosis and to find a better treatment according to the cancer molecular type.

Homozygous familial hypercholesterolaemia (HoFH) is characterised by extremely elevated levels of low-density lipoprotein cholesterol (LDL-C) and results from multiple mutations in genes affecting the LDL receptor pathway. Patients are at risk of premature atherosclerotic cardiovascular disease (ASCVD) and premature death. Lomitapide is a microsomal triglyceride transfer protein inhibitor developed to treat HoFH, but cardiovascular outcome data are lacking.We evaluated detailed data from five HoFH patients and one patient with heterozygous FH (HeFH) and a very severe phenotype. We also analysed confirmatory data from a further 8 HoFH cases. In total, we analysed data from patients in seven global centres in six countries who were all treated with lomitapide with long-term follow-up. Carotid intima-media thickness (CIMT) imaging was recorded on an ad hoc basis to monitor ASCVD in HoFH.Lomitapide resulted in marked decreases in LDL-C of 56.8-93.9% [77.7-93.9% in the 6 initial cases (mean nadir 64.8 ± 30.1 mg/dL); 56.8-86.0% in the 8 confirmatory cases (mean nadir 131.4 ± 38.2 mg/dL)]. CIMT regressed in 50% of cases (mean follow-up 5.0 ± 3.1 years in initial six cases, and 4.4 ± 1.4 years in confirmatory cases). In the remaining patients, CIMT showed little further change. In patients where assessments of plaque area were available, regression or stabilisation in CIMT was accompanied by clinically significant regression of plaque area.Lomitapide reduces LDL-C levels in patients with HoFH and severe LDL-C phenotypes, and results in stabilisation and/or regression of CIMT, which is an established marker of ASCVD risk. Additional data are needed to determine if this confers a survival benefit in these very high-risk patients.

HTE 3.0 aims to support clinicians in the detection of patients with dyslipidemia, especially patients with familial hypercholesterolemia (FH), and in the recommendation of personalized lipid-lowering treatments. The core of HTE 3.0 is a clinical decision support system in which several knowledge-based systems are serialized: patient detection, therapeutic target setting, personalized treatment assessment, and treatment combination and prioritization, according to different criteria. The experimental evaluation of HTE 3.0 shows that the use of HTE 3.0 would mean increasing the capacity to detect FH by 5.7 times compared with usual clinical practice. Regarding the lipid-lowering treatment, a comparison of 18 cases among seven lipidologists shows that the differences between treatments provided by HTE 3.0 and human lipidologists are smaller than the differences between human experts This work has been developed with the support of the research group SITES awarded with distinction by the Generalitat de Catalunya(2017 SGR 1551) Open Access funding provided thanks to the CRUE-CSIC agreement with Wiley

Pooled data from randomized clinical trials on lipid-lowering therapy have provided valuable information and clinical insights. Although cardiovascular disease is a common cause of death, mortality data have rarely been prominent in key lipid trials. The 4S, LIPID and HPS trials were the first to demonstrate a reduction in overall mortality. Lower- versus higher-intensity statin trials and non-statin lipid-lowering trials with ezetimibe and proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors proved that additional lipid lowering significantly reduces the occurrence of cardiovascular events. However, only the ODYSSEY OUTCOMES trial showed a reduction in all-cause mortality. The aim of the present narrative review was to contrast these results with those of other key lipid trials: those assessing statins compared with placebo, those evaluating intensive- versus moderate-intensity lipid-lowering therapy and, finally, those investigating non-statin lipid-lowering therapies.

One of the main goals of the Spanish Society of Arteriosclerosis is to contribute to a wider and greater knowledge of vascular disease, its prevention and treatment. Cardiovascular diseases are the leading cause of death in our country and also lead to a high degree of disability and health expenditure. Arteriosclerosis is a multifactorial disease, this is why its prevention requires a global approach that takes into account the different risk factors with which it is associated. Thus, this document summarizes the current level of knowledge and integrates recommendations and procedures to be followed for patients with established cardiovascular disease or high vascular risk. Specifically, this document reviews the main symptoms and signs to be evaluated during the clinical visit, the laboratory and imaging procedures to be routinely requested or those in special situations. It also includes the estimation of vascular risk, the diagnostic criteria of the different entities that are cardiovascular risk factors, and presents general and specific recommendations for the treatment of the different cardiovascular risk factors and their final objectives. Finally, the document includes aspects that are not often mentioned in the literature, such as the organisation of a vascular risk consultation.

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.

Introduction and objectives PCSK9 inhibitors (PCSK9i) are safe and effective lipid-lowering drugs . Their main limitation is their high cost. The aim of this study was to estimate the number of patients eligible for treatment with PCSK9i according to distinct published criteria. Methods Data were obtained from the Information System for the Development of Research in Primary Care. Included patients were equal to or older than 18 years and had at least 1 low-density lipoprotein cholesterol measurement recorded between 2006 and 2014 (n = 2 500 907). An indication for treatment with PCSK9i was assigned according to the following guidelines: National Health System, Spanish Society of Arteriosclerosis , Spanish Society of Cardiology, National Institute for Health and Care Excellence, and the European Society of Cardiology/European Atherosclerosis Society Task Force. Lipid-lowering treatment was defined as optimized if it reduced low-density lipoprotein levels by ≥ 50% and adherence was > 80%. Results Among the Spanish population aged 18 years or older, the number of possible candidates to receive PCSK9i in an optimal lipid-lowering treatment scenario ranged from 0.1% to 1.7%, depending on the guideline considered. The subgroup of patients with the highest proportion of potential candidates consisted of patients with familial hypercholesterolemia , and the subgroup with the highest absolute number consisted of patients in secondary cardiovascular prevention. Conclusions The number of candidates to receive PCSK9i in conditions of real-world clinical practice is high and varies widely depending on the recommendations of distinct scientific societies.

El objetivo del estudio es estimar el numero de pacientes candidatos a recibir iPCSK9 segun los diferentes criterios publicados. Metodos Los datos provienen del Sistema de Informacion para la Investigacion en Atencion Primaria. Se incluyo a pacientes de edad ≥ 18 anos con al menos una determinacion de colesterol unido a lipoproteinas de baja densidad entre 2006 y 2014 (n = 2.500.907). Los criterios de indicacion terapeutica de iPCSK9 analizados fueron: Sistema Nacional de Salud, Sociedad Espanola de Arteriosclerosis, Sociedad Espanola de Cardiologia, National Institute for Health and Care Excellence y Sociedad Europea de Cardiologia/European Atherosclerosis Society Task Force. Se definio como tratamiento lipidico optimizado el que alcanzara una reduccion del colesterol unido a lipoproteinas de baja densidad ≥ 50% y un cumplimiento > 80%. Resultados En la poblacion espanola de 18 o mas anos el numero de posibles candidatos a recibir iPCSK9 en un escenario de tratamiento hipolipemiante optimo oscila entre el 0,1 y el 1,7% segun los diferentes criterios. El subgrupo con mayor porcentaje de candidatos seria el de los pacientes con hipercolesterolemia familiar, y el mayor numero absoluto vendria de los pacientes en prevencion secundaria. Conclusiones El numero de posibles candidatos a recibir iPCSK9 en condiciones de practica clinica es muy alto y varia mucho segun las recomendaciones de las diferentes sociedades cientificas.

International audience; Background and aimsThis European Atherosclerosis Society (EAS) Task Force provides practical guidance for combination therapy for elevated low-density lipoprotein cholesterol (LDL-C) and/or triglycerides (TG) in high-risk and very-high-risk patients.MethodsEvidence-based review.ResultsStatin-ezetimibe combination treatment is the first choice for managing elevated LDL-C and should be given upfront in very-high-risk patients with high LDL-C unlikely to reach goal with a statin, and in primary prevention familial hypercholesterolaemia patients. A proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor may be added if LDL-C levels remain high. In high and very-high-risk patients with mild to moderately elevated TG levels (>2.3 and < 5.6 mmol/L [>200 and < 500 mg/dL) on a statin, treatment with either a fibrate or high-dose omega-3 fatty acids (icosapent ethyl) may be considered, weighing the benefit versus risks. Combination with fenofibrate may be considered for both macro- and microvascular benefits in patients with type 2 diabetes mellitus.ConclusionsThis guidance aims to improve real-world use of guideline-recommended combination lipid modifying treatment.

International audience; Elevated levels of low-density lipoprotein cholesterol (LDL-C) are associated with increased risk of coronary heart disease and stroke. Guidelines for the management of dyslipidaemia from the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) were updated in late 2019 in light of recent intervention trials involving the use of innovative lipid-lowering agents in combination with statins. The new guidelines advocate achieving very low LDL-C levels in individuals at highest risk, within the paradigm of 'lower is better'. With the advent of combination therapy using ezetimibe and/or proprotein convertase subtilisin/kexin type 9 inhibitors in addition to statins, the routine attainment of extremely low LDL-C levels in the clinic has become a reality. Moreover, clinical trials in this setting have shown that, over the 5-7 years of treatment experience to date, profound LDL-C lowering leads to further reduction in cardiovascular events compared with more moderate lipid lowering, with no associated safety concerns. These reassuring findings are bolstered by genetic studies showing lifelong very low LDL-C levels (

The widespread use of statins has largely improved the treatment of hypercholesterolemia, but many patients still fail to achieve the LDL-C targets recommended by guidelines. Furthermore, some patients continue to present a very high cardiovascular (CV) risk or even an extreme risk despite being well treated, mainly due to the presence of co-morbidities such as diabetes or peripheral artery disease, which significantly increase their global CV risk. For these very high CV risk patients, the most recent European guidelines have reviewed the LDL-C goals and recommend an LDL-C reduction of at least 50% and a goal of55 mg/dL or even40 mg/dL. Recent clinical trials have shown that patient stratification based on the presence or absence of atherothrombotic risk factors may represent a valuable tool to identify patients at extremely high CV risk who may benefit more from an aggressive LDL-C-lowering approach. In these patients it may be appropriate to aim for the lowest LDL-C level, independently of recommended goals, with all the available pharmacological approaches.

Background 2016 and 2019 EAS/ESC dyslipidemia guidelines recommend lipid lowering therapy (LLT) to reduce LDL-C in patients with peripheral arterial disease (PAD) with or without established cardiovascular (CV) disease, and recommend target LDL-C goals based on individual CV risk. Data regarding the implementation of these guidelines in clinical practice across Europe is currently lacking. Purpose Describe LLT and achievement of the target LDL-C goals recommended in EAS/ESC dyslipidemia guidelines in patients with PAD. Methods The cross-sectional Da Vinci study enrolled consenting adults who had received LLT in the 12 months prior to the study visit and had at least one LDL-C measurement in the 14 months prior to the study visit, seen in a primary or secondary care setting across 18 European countries. Patients with coronary, peripheral and cerebral disease were enrolled at a ratio of 1:2:2. FH patients with prior CV events were excluded. Data were collected from medical records at a single visit between Jun '17–Nov '18, including LLT and most recent LDL-C. Primary outcome was LDL-C goal attainment ≥28 days after starting most recent LLT (treatment-stabilised LLT). Results Of 5888 patients enrolled, 2794 met our definition of atherosclerotic cardiovascular disease (ASCVD). Of these ASCVD patients, 1036 (37%) had PAD. 31% (323/1036) of PAD patients were female and mean (SD) age was 69 (9.4) years. Concomitant CV risk factors included diabetes mellitus (473/1036 patients [46%]), hypertension (809/1036 [78%]) and smoking (794/1036 [77%]). 26% (271/1036) of patients with PAD also had coronary vascular disease and 12% (122/1036) also had cerebrovascular disease. At the visit date, approximately half (497/1036 [48%]) of all PAD patients were receiving moderate intensity statins and 41% (421/1036) were receiving high intensity statins. 818 (73%) of the PAD patients had a treatment-stabilised LDL-C measurement (median, 2.20 mmol/L), of whom 40% (326/818) achieved the 2016 EAS/ESC LDL-C goal of 1.8 mmol/L and only 19% (159/818) achieved the 2019 goal of 1.4mmol/L. Conclusions European patients with PAD are not treated as per EAS/ESC recommendations, with a large proportion receiving suboptimal LLT and fewer than half achieving target LDL-C levels.

Background and aims Both the Nordic and Mediterranean diets claim to have a beneficial effect on lipid metabolism and cardiovascular prevention. The objective of this study was to compare diets consumed by children with FH at the time of diagnosis in Norway and Spain and to study their relationship with the lipid profile. Methods and results In this cross-sectional study, we appraised the dietary intake in children (4–18 years old) with (n = 114) and without FH (n = 145) from Norway and Spain. We compared Nordic and Mediterranean diet composition differences and determined the association between food groups and lipid profiles. Results The Spanish FH group had a higher intake of total fats (mainly monounsaturated fatty acids (MUFAs)), cholesterol and fibre, but a lower intake of polyunsaturated fatty acids (PUFAs) compared to the Norwegian FH group. The Norwegian children consumed more rapeseed oil, low-fat margarine and whole grains and less olive oil, eggs, fatty fish, meat, legumes and nuts. In the Norwegian FH group, fat and MUFAs were directly correlated with total cholesterol, low-density lipoprotein cholesterol and apolipoprotein B and inversely correlated with high-density lipoprotein (HDL-C). In Spanish children with FH, the intake of fats (mainly MUFAs) was directly associated with HDL-C and apolipoprotein A1. Conclusions Despite a similar lipid phenotype, diets consumed by children with FH in Norway and Spain have significant differences at time of diagnosis. Nutrition advice should be more adapted to local intake patterns than on specific nutrient composition.

Background and aims: Post-acute coronary syndrome (ACS) patients are at very high risk for recurrent events and mortality, despite the availability of effective pharmacological approaches. Aim of this survey was to evaluate the compliance to ESC/EAS guidelines during the management of ACS patients and the effectiveness of secondary prevention in seven European countries.Methods: By means of an online questionnaire, data on 2775 ACS patients (either acute case or follow-up patients) were collected, including data on lipid profile, medications, follow-up visit planning, screening for familial hypercholesterolemia.Results: Lipid profiles were obtained for 91% of ACS patients in the acute phase, mostly within the first day of hospitalization (73%). During hospitalization, 93% of the patients received a lipid-lowering treatment; at discharge, only 66% of the patients received a high intensity statin therapy. At the first follow-up, most of the patients (77.6%) had LDL-C 70 mg/dL; among them, 41% had no change in their lipid-lowering therapies. Similar data were obtained during the second follow-up visit. The analysis of a subgroup of patients with at least 2 follow-up visits and known LDL-C levels showed that the percentage of patients at goal increased from 9% to 32%, and patients with LDL-C

Metabolic-associated fatty liver disease (MAFLD), the main cause of chronic liver disease worldwide, is a progressive disease ranging from fatty liver to steatohepatitis (metabolic-associated steatohepatitis; MASH). Nevertheless, it remains underdiagnosed due to the lack of effective non-invasive methods for its diagnosis and staging. Although MAFLD has been found in lean individuals, it is closely associated with obesity-related conditions. Adipose tissue is the main source of liver triglycerides and adipocytes act as endocrine organs releasing a large number of adipokines and pro-inflammatory mediators involved in MAFLD progression into bloodstream. Among the adipocyte-derived molecules, fatty acid binding protein 4 (FABP4) has been recently associated with fatty liver and additional features of advanced stages of MAFLD. Additionally, emerging data from preclinical studies propose FABP4 as a causal actor involved in the disease progression, rather than a mere biomarker for the disease. Therefore, the FABP4 regulation could be considered as a potential therapeutic strategy to MAFLD. Here, we review the current knowledge of FABP4 in MAFLD, as well as its potential role as a therapeutic target for this disease.

Resumen Introduccion La hipercolesterolemia familiar (HF) infantil esta infradiagnosticada y su diagnostico no es facil en la practica clinica. El objetivo fue evaluar que caracteristicas clinicas, bioquimicas y de imagen vascular pueden ayudarnos a detectar a ninos/as y adolescentes con hipercolesterolemia afectados de HF. Metodos Doscientos veintidos ninos y adolescentes de entre 4 y 18 anos fueron reclutados para participar en un proyecto de deteccion precoz de HF (proyecto DECOPIN). La HF se diagnostico por criterios geneticos o clinicos. Se definio hipercolesterolemia poligenica (HP) cuando el c-LDL >135 mg/dl pero sin criterios clinicos ni geneticos de HF. Participantes con c-LDL Resultados Noventa y un ninos fueron diagnosticados de HF y 23 de HP, y 108 como GC. El grupo HF presento mayores concentraciones de CT, c-LDL, indice ApoB/ApoA1 e indice colesterol ano. El c-HDL fue menor en grupo HF que en el GC. Si bien el c-LDL fue el parametro mas definitorio de HF, el indice ApoB/ApoA1 > 0,82 fue el que de forma aislada mostro mayor sensibilidad y especificad para predecir la presencia de mutacion en el grupo de ninos HF. El grosor de los tendones de Aquiles no mostro diferencias entre grupos. El GIMc fue mayor en los ninos HF sin diferencias significativas. Conclusiones Los niveles de c-LDL son el marcador de HF. Un indice ApoB/ApoA1 > 0,82 puede ser una herramienta util para decidir el estudio genetico en ninos con sospecha de HF.

Background Autosomal recessive hypercholesterolemia (ARH) is a rare lipid disorder characterized by premature atherosclerotic cardiovascular disease (ASCVD). There are sparse data for clinical management and cardiovascular outcomes in ARH. Objectives Evaluation of changes in lipid management, achievement of low-density lipoprotein cholesterol (LDL-C) goals and cardiovascular outcomes in ARH. Methods Published ARH cases were identified by electronic search. All corresponding authors and physicians known to treat these patients were asked to provide follow-up information, using a standardized protocol. Results We collected data for 52 patients (28 females, 24 males; 31.1 ± 17.1 years of age; baseline LDL-C: 571.9 ± 171.7 mg/dl). During a mean follow-up of 14.1 ± 7.3 years, there was a significant increase in the use of high-intensity statin and ezetimibe in combination with lipoprotein apheresis; in 6 patients, lomitapide was also added. Mean LDL-C achieved at nadir was 164.0 ± 85.1 mg/dl (−69.6% from baseline), with a better response in patients taking lomitapide (−88.3%). Overall, 23.1% of ARH patients reached LDL-C of Conclusions Despite intensive treatment, LDL-C in ARH patients remains far from targets, and this translates into a poor long-term cardiovascular prognosis. Our data highlight the importance of an early diagnosis and treatment and confirm the fact that an effective treatment protocol for ARH is still lacking.

Simple Summary Previously, our group demonstrated high FABP4 circulating levels in breast cancer (BC) patients. Moreover, increased cholesterol and triglycerides (TG) were found. To deeply analyse the lipid metabolism in our BC cohort, lipid and low molecular weight metabolomics processes are performed in 240 women (171 BC and 69 control women). This paper provides original data related to a novel link between TG-enriched particles and BC. The main result of this study is that TG-enriched particles and some branched amino acids, as well as tyrosine and alanine, are positively associated with BC. This suggests that BC patients have a different metabolic signature that could be used for better stratification and treatment. To our knowledge, this is the first time that advanced NMR profiling has been used to identify relevant and specifically altered lipid and amino acid metabolites in BC serum samples, which could be used for early and reliable diagnosis and prognosis. Abstract Background: Altered lipid metabolism has been described in some types of cancer. To analyse in depth the metabolic modifications in breast cancer patients, advanced 1H-nuclear magnetic resonance was performed in these patients. The main objective of this paper was to define a specific lipidomic signature for these cancer patients. Materials and methods: Serum from 240 women (171 breast cancer patients and 69 control women) were studied and analysed by nuclear magnetic resonance. Results: Triglyceride-enriched particles, specifically very low-density lipoprotein triglycerides, intermediate-density lipoprotein triglycerides, low-density lipoprotein triglycerides, and high-density lipoprotein triglycerides, were positively associated with breast cancer. Moreover, alanine, tyrosine, and branched amino acids were also associated with increased risk of breast cancer. Conclusions: Breast cancer patients showed a modified metabolome, giving a very interesting tool to draw different radar charts between control women and breast cancer patients. To our knowledge, this is the first time that advanced nuclear magnetic resonance profiling has been used to identify relevant and specifically altered lipid or amino acid metabolites in BC serum samples. The altered metabolic signature could be analysed for early and reliable BC patient diagnosis and prognosis.

Background Evolocumab, a fully human monoclonal antibody against proprotein convertase subtilisin/kexin type 9, is safe and effective when dosed biweekly (Q2W) or monthly (QM) in patients with heterozygous familial hypercholesterolemia (HeFH) as demonstrated in two 12-week trials: Reduction of LDL-C With PCSK9 Inhibition in Heterozygous Familial Hypercholesterolemia Disorder (RUTHERFORD; phase 2) and RUTHERFORD-2 (phase 3). Objective The objective of the study was to evaluate long-term efficacy, safety, and tolerability of evolocumab during open-label extension trials. Methods Patients completing parent trials were re-randomized 2:1 to evolocumab plus standard of care (SOC) or SOC alone for 52 weeks (Open-Label Study of Long-term Evaluation Against LDL-C [OSLER-1]) or 48 weeks (OSLER-2). Evolocumab dosing was 420 mg QM (OSLER-1) and 140 mg Q2W or 420 mg QM (OSLER-2). A pooled analysis of OSLER data was performed from this subset of HeFH patients. Results Four hundred forty HeFH patients from RUTHERFORD (n = 147) and RUTHERFORD-2 (n = 293) (mean [standard deviation] age 51 [12] years, 58% male, 90% White) were randomized to evolocumab plus SOC (n = 289) or SOC (n = 151). The 48-week period was completed by 425 patients (96.6%). Eight patients discontinued evolocumab plus SOC (2.8%) and 7 discontinued SOC (4.6%). Compared to parent study baseline, patients receiving evolocumab plus SOC experienced a mean 53.6% reduction in low-density lipoprotein cholesterol after 48 weeks. No patient experienced an adverse event leading to permanent evolocumab discontinuation during the 1-year SOC-controlled period. Serious adverse event rates were similar between groups (evolocumab plus SOC, 7.3%; SOC, 8.6%). Conclusion Continued use of evolocumab added to SOC in patients with HeFH yields persistent and marked low-density lipoprotein cholesterol reductions during 48 weeks of follow-up. Long-term dosing of evolocumab with SOC was safe and well tolerated.

We report the case of a patient treated at the lipid clinic because of high cholesterol levels with consistently elevated creatine kinase concentrations that precluded statin treatment. Electromyography showed a rippling muscle disease pattern. A muscle biopsy confirmed caveolin 3 deficiency, and a missense mutation in the CAV3 gene was identified. The patient could be properly managed with ezetimibe and cholestyramine, which reduced the low-density lipoprotein cholesterol by 30%. He remains asymptomatic after 10 years of follow-up. Caveolae and caveolins are essential to membrane integrity, and their deficit has been associated with insulin resistance and hypercholesterolemia in animal models. Therefore, a putative pathophysiological association between myopathy and lipid metabolism mediated by functional alterations of membrane receptors is considered.

Current research is focused on improving high-density lipoprotein (HDL) function rather than simply targeting an increase in high-density lipoprotein-cholesterol (HDL-C) levels [(1)][1]. The results of several recent studies indicate that stimulation of the HDL-dependent cholesterol efflux from

Background and aims The first line of therapy in children with hypercholesterolaemia is therapeutic lifestyle changes (TLSC). The efficacy of lifestyle intervention in children with familial hypercholesterolaemia (FH), where LDL-C levels are genetically driven, deserves a focused study. Aims To evaluate the impact of a lifestyle education program, focused on food patterns and physical activity, on lipid profiles assessed by nuclear magnetic resonance (NMR) in children with FH vs. non-FH. Methods Phase 1 was a cross-sectional study of baseline characteristics, and phase 2 was a prospective TLSC intervention study. In total, the study included 238 children (4 to 18 years old; 47% girls) attending the lipid unit of our hospital due to high cholesterol levels. Eighty-five were diagnosed with FH (72% genetic positive), and 153 were diagnosed with non-Familial hypercholesterolaemia. A quantitative food frequency questionnaire (FFQ) including 137 items was used. Physical activity (PA) was assessed by the Minnesota questionnaire. The lipid profile was assessed using the 2D-1H-NMR (Liposcale test). A total of 127 children (81 in the FH group) participated in the prospective phase and were re-assessed after 1 year of the TLSC intervention, consisting of education on lifestyle changes delivered by a specialized nutritionist. Results The FH and non-FH groups were similar in anthropometry and clinical data, except that those in the FH were slightly younger than those in the non-FH group. Both the FH and non-FH groups showed a similar diet composition characterized by a high absolute calorie intake and a high percentage of fat, mainly saturated fat. The PA was below the recommended level in both groups. After one year of TLSC, the percentage of total and saturated fats was reduced, and the amount of fiber increased significantly in both groups. The percentage of protein increased slightly. The number of children engaged in at least 1 hour/day of PA increased by 56% in the FH group and by 53% in the non-FH group, and both these increases were significant. The total and small-LDL particle numbers were reduced in both groups, although the absolute change was greater in the FH group than in the non-FH group. Conclusions Educational strategies to implement TLSC in children lead to empowerment, increased adherence, and overall metabolic improvement in children with high blood cholesterol, including those with FH.

In the statin era, the incidence of atherosclerotic cardiovascular diseases (ASCVD) in patients with familial hypercholesterolemia (FH) has not been updated. We aimed to determine the incidence of ASCVD in patients with FH-phenotype (FH-P) and to compare it with that of normal low-density lipoprotein cholesterol (LDL-C) patients. We performed a retrospective cohort study using the Database of the Catalan primary care system, including &ge, 18-year-old patients with an LDL-C measurement. From 1,589,264 patients available before 2009, 12,823 fulfilled FH-P criteria and 514,176 patients were normolipidemic (LDL-C &lt, 115 mg/dL). In primary prevention, patients with FH-P had incidences of ASCVD and coronary heart disease (CHD) of 14.9/1000 and 5.8/1000 person-years, respectively, compared to 7.1/1000 and 2.1/1000 person-years in the normolipidemic group. FH-P showed hazard ratio (HR) of 7.1 and 16.7 for ASCVD and CHD, respectively, in patients younger than 35 years. In secondary prevention, patients with FH-P had incidences of ASCVD and CHD of 89.7/1000 and 34.5/1000 person-years, respectively, compared to 90.9/1000 and 28.2/1000 person-years in the normolipidemic group (HR in patients younger than 35 years: 2.4 and 6.0). In the statin era, FH-P remains associated with high cardiovascular risk, compared with the normolipidemic population. This excess of risk is markedly high in young individuals.

T***he current control of low-density lipoprotein cholesterol among patients with atherosclerotic cardiovascular disease is very low and this is associated with an increase of cardiovascular outcomes. In addition, the latter this happens, the risk will be greater. This is mainly due to an insufficient use of the lipid-lowering therapy currently available. In fact, with current treatments (statins, ezetimibe and PCSK9 inhibitors), the majority of patients in secondary prevention should achieve low-density lipoprotein cholesterol goals. For these reasons, in this manuscript promoted by the Spanish Society of Cardiology we propose three simple and feasible decision-making algorithms that include the majority of clinical scenarios among patients with ischemic heart disease, with the double aim of attaining therapeutic goals in the majority of patients as soon as possible; in secondary prevention the magnitude of the benefit is risk- and time-dependent.

One of the main goals of the Spanish Society of Arteriosclerosis is to contribute to a wider and greater knowledge of vascular disease, its prevention and treatment. Cardiovascular diseases are the leading cause of death in our country and also lead to a high degree of disability and health expenditure. Arteriosclerosis is a multifactorial disease, this is why its prevention requires a global approach that takes into account the different risk factors with which it is associated. Thus, this document summarizes the current level of knowledge and integrates recommendations and procedures to be followed for patients with established cardiovascular disease or high vascular risk. Specifically, this document reviews the main symptoms and signs to be evaluated during the clinical visit, the laboratory and imaging procedures to be routinely requested or those in special situations. It also includes the estimation of vascular risk, the diagnostic criteria of the different entities that are cardiovascular risk factors, and presents general and specific recommendations for the treatment of the different cardiovascular risk factors and their final objectives. Finally, the document includes aspects that are not often mentioned in the literature, such as the organisation of a vascular risk consultation.

Introduction Homozygous familial hypercholesterolaemia (HoFH) is a rare, autosomal disease affecting the clearance of low-density lipoprotein cholesterol (LDL-C) from circulation, and leading to early-onset atherosclerotic cardiovascular disease (ASCVD). Treatment consists mainly of statins, lipoprotein apheresis (LA) and, more recently, the microsomal triglyceride transfer protein inhibitor lomitapide. Lomitapide is not licensed for use in children, but has been made available through an expanded access programme or on a named patient basis. Methods This case series includes 11 HoFH patients in 10 different centres in eight countries, less than 18 years of age (mean 11.6 ± 1.1 years, 64% male), with signs of ASCVD, and who have received treatment with lomitapide (mean dose 24.5 ± 4.3 mg/day; mean exposure 20.0 ± 2.9 months). Background lipid-lowering therapy was given according to local protocols. Lomitapide was commenced with a stepwise dose escalation from 2.5 mg or 5 mg/day; dietary advice and vitamin supplements were provided as per the product label for adults. Laboratory analysis was conducted as part of regular clinical care. Results In the 11 cases, mean baseline LDL-C was 419 ± 74.6 mg/dL and was markedly reduced by lomitapide to a nadir of 176.7 ± 46.3 mg/dL (58.4 ± 6.8% decrease). Six patients achieved recommended target levels for children below 135 mg/dL, five of whom had LA frequency reduced. In one case, LDL-C levels were close to target when lomitapide was started but remained stable despite 75% reduction in LA frequency (from twice weekly to biweekly). Adverse events were mainly gastrointestinal in nature, occurred early in the treatment course and were well managed. Three patients with excursions in liver function tests were managed chiefly without intervention; two patients had decreases in lomitapide dose. Conclusions Lomitapide demonstrated promising effectiveness in paediatric HoFH patients. Adverse events were manageable, and the clinical profile of the drug is apparently similar to that in adult patients. Funding Amryt Pharma.

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.
