RESUMEN
BACKGROUND AND AIMS: Familial hypercholesterolaemia (FH) is a highly prevalent monogenic disorder characterized by elevated LDL cholesterol (LDL-C) levels and premature atherosclerotic cardiovascular disease. Sex disparities in diagnosis, lipid-lowering therapy, and achieved lipid levels have emerged worldwide, resulting in barriers to care in FH. A systematic review was performed to investigate sex-related disparities in treatment, response, and lipid target achievement in FH (PROSPERO, CRD42022353297). METHODS: MEDLINE, Embase, The Cochrane library, PubMed, Scopus, PsycInfo, and grey literature databases were searched from inception to 26 April 2023. Records were eligible if they described sex differences in the treatment of adults with FH. RESULTS: Of 4432 publications reviewed, 133 met our eligibility criteria. In 16 interventional clinical trials (eight randomized and eight non-randomized; 1840 participants, 49.4% females), there were no differences between males and females in response to fixed doses of lipid-lowering therapy, suggesting that sex was not a determinant of response. Meta-analysis of 25 real-world observational studies (129 441 participants, 53.4% females) found that females were less likely to be on lipid-lowering therapy compared with males (odds ratio .74, 95% confidence interval .66-.85). Importantly, females were less likely to reach an LDL-C < 2.5 mmol/L (odds ratio .85, 95% confidence interval .74-.97). Similarly, treated LDL-C levels were higher in females. Despite this, male sex was associated with a two-fold greater relative risk of major adverse cardiovascular events including myocardial infarction, atherosclerotic cardiovascular disease, and cardiovascular mortality. CONCLUSIONS: Females with FH were less likely to be treated intensively and to reach guideline-recommended LDL-C targets. This sex bias represents a surmountable barrier to clinical care.
RESUMEN
PURPOSE: Familial hypercholesterolemia (FH) leads to elevated low-density lipoprotein cholesterol levels, which increases the risk of premature atherosclerotic cardiovascular disease (ASCVD). Since the first functional and morphologic changes of the arterial wall occur in childhood, treatment should start early in childhood to mitigate the elevated risk of ASCVD. Pediatricians play an important role in the detection and care of children with FH. In this study, we aim to explore potential gaps in FH care amongst Dutch pediatricians, in order to enhance their knowledge and awareness of detecting and treating children with FH. METHODS: An anonymous online survey, deployed using Google Forms, including 26 closed and semi-closed questions on FH care in children was distributed by the Dutch Association of Pediatrics via a newsletter to which the majority of the practicing Dutch pediatricians subscribe. In addition, we requested that the pediatric departments of all Dutch hospitals in the Netherlands distribute this survey personally among their employed pediatricians. Respondents were instructed to answer the questions without any help or use of online resources. RESULTS: Between September 1st, 2023 and November 1st, 2023, 158 (an estimated 11% response rate) Dutch pediatricians completed the survey. They reported a median (IQR) of 15.0 (6.0-22.0) years of experience as a pediatrician, and 34 (21.5%) were working in academic hospitals. The majority (76.6%) of pediatricians correctly identified a typical FH lipid profile but 68 (43.0%) underestimated the true prevalence of FH (1:300). Underestimation and unawareness of the increased risk of FH patients for ASCVD were reported by 37.3% and 25.9% of pediatricians, respectively. Although 70.9% of the pediatricians correctly defined FH, only 67 (42.4%) selected statins and ezetimibe to treat severe hypercholesterolemia. CONCLUSIONS: The results of this study suggest significant gaps in knowledge and awareness of FH in children among Dutch pediatricians. FH care in children needs improvement through educational and training initiatives to mitigate the life-long risk of ASCVD from early life. WHAT IS KNOWN: ⢠Familial hypercholesterolemia (FH) leads to elevated LDL-cholesterol levels, which increases the risk of premature atherosclerotic cardiovascular disease (ASCVD). ⢠The process of atherosclerosis starts in childhood ⢠Pediatricians play an important role in the detection and treatment of children with FH. WHAT IS NEW: ⢠Our results highlight significant gaps in care for children with FH amongst pediatricians and this may lead to suboptimal detection and treatment. ⢠FH care in children needs improvement by educational initiatives to ultimately prevent ASCVD in adulthood.

Familial hypercholesterolemia (FH) is an inherited metabolic defect leading to increased total cholesterol and low-density cholesterol (LDL) from birth onwards. Homozygous FH, presenting with clear clinical features, has a prevalence of ~ 1 per million. Prevalence of heterozygous FH is 1/500 European population. Atherosclerotic burden depends on the degree and duration of high LDL exposure. In severe cases, early detection is critical, and aggressive lipid-lowering therapies should begin in early childhood to reduce coronary heart disease risk. Pediatric therapeutic concepts correspond to adults and are orientated at LDL plasma concentration. Mean LDL plasma target value during treatment is < 135 mg/dL. Medication in childhood consists of ezetemibe, statins, resins, and PCSK-9 inhibitors, with consideration for age restrictions. Only a minority achieve the treatment target with drug therapy alone. Therapeutic apheresis for the treatment of hypercholesterolemia selectively removes lipoproteins from blood (lipid apheresis (LA)). LA has a long tradition in adult medicine and is also safely used in children by a variety of methods, if customized to special pediatric needs. LA reduces cholesterol levels independently of residual LDL-receptor function and not only achieves reduction or disappearance of xanthomas but also inhibits progression of or mitigates aortic valve stenosis and supravalvular aortic stenosis as well as coronary artery and other atherosclerotic lesions. Cardiovascular prognosis of patients with otherwise untreatable FH depends largely on timely use of LA. Taking into account LA as a lifelong treatment, starting early in childhood, it is important to accommodate therapy modalities, such as treatment frequency and point of time, into the life of the individual.

BACKGROUND AND AIMS: Several works have shown that control of the principal cardiovascular risk factors, especially LDL-C, is poorer among women with type 2 diabetes than men with this disease. Our objectives were to compare the statin treatments and LDL-C levels between men and women with type 2 diabetes, according to the potency of the statin they take, while taking their cardiovascular risk level into account. METHOD AND RESULTS: This is a descriptive cross-sectional study within the French CONSTANCES cohort. At inclusion, each individual completed several self-administered questionnaires. Data were then matched to their health insurance fund reimbursement data. The study population comprises cohort members with pharmacologically treated type 2 diabetes. We identified 2541 individuals with type 2 diabetes; 2214 had an available LDL-C value. In the total sample, treatment by statins did not differ between men and women, while the women had a higher mean LCL-C level than men. The analyses stratified by cardiovascular risk showed that women at very high cardiovascular risk received significantly less frequent statin delivery than men (OR = 0.72 [0.56-0.92]; p = 0.01). At the same time, women received the same rate of high-potency statins as men. Women taking equivalently potent statins had significantly higher LDL-C levels than men did. CONCLUSION: For the same cardiovascular risk level and the same statin treatment, women had an LDL-C level higher than that of men. They thus present a residual cardiovascular risk that justifies intensification of their statin treatment if tolerance allows.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a new class of potent lipid-lowering drugs. Oxidized low-density lipoprotein (ox-LDL) is the key pathogenic factor leading to atherosclerosis. However, its effect on ox-LDL levels has not been clinically reported. The clinical data of 290 very high-risk atherosclerotic cardiovascular disease (ASCVD) patients diagnosed in the First Affiliated Hospital of Zhengzhou University from May 2022 to October 2022 were collected retrospectively. According to whether evolocumab (a PCSK9 inhibitor) was used after percutaneous coronary intervention (PCI), they were divided into evolocumab group (153 cases) and statin monotherapy group (137 cases). At hospital admission, ox-LDL, total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoproteinA1 (apoA1), apolipoprotein B-100 (apoB), lipoprotein (a) [Lp(a)], and high-sensitivity reactive protein (hs-CRP) levels were collected and used as baseline data. After two weeks of treatment, ox-LDL in the evolocumab group and statin monotherapy group were significantly lower than those before treatment (p<0.05). The decrease of ox-LDL in the evolocumab group was more than in the stain monotherapy group (p<0.05). In conclusion, PCSK9 inhibitors reduce ox-LDL levels in very high-risk ASCVD patients in a short time.
RESUMEN
Nowdays a small proportion of patients with high/very high/extreme atherosclerotic cardiovascular disease risk achieves the optimal target of LDL-cholesterol, because of drug intolerance, poor adherence to the therapy, or inapplicability of the stepwise strategy in lipid lowering therapy, recommended by the current guidelines. The new oral agent bempedoic acid lowers plasma LDL-cholesterol by inhibiting adenosine triphosphate-citrate lyase, an enzyme involved in the synthesis of cholesterol, and, ultimately, by up-regulating the LDL receptors. Several clinical trials in patients with atherosclerotic cardiovascular disease or familial heterozygous hypercholesterolemia demonstrated that bempedoic acid alone or combined with statins and/or ezetimibe significantly reduced LDL-cholesterol and high-sensitivity C-reactive protein. Bempedoic acid is well tolerated with no significant increase in muscle-related symptoms, since it can be activated only in the liver but not in the skeletal muscles. Bempedoic acid provides an effective tool to further reduce LDL-cholesterol as add on therapy in patients unable to reach the target despite maximally tolerated lipid lowering therapy.
RESUMEN
PURPOSE: Low-density lipoprotein (LDL) cholesterol reduction by statin therapy is dose-dependent, varies among different statins, and has wide inter-individual variability. The present study aimed to compare mean LDL cholesterol reduction and its variability achieved with different doses of the three statins most frequently used in monotherapy or combined with ezetimibe in a real clinical setting. METHODS: Of 5620 cases with primary hypercholesterolemia on the Spanish Arteriosclerosis Society Registry, 1004 with non-familial hypercholesterolemia and complete information on drug therapy and lipid profile were included. RESULTS: The lowest mean percentage LDL cholesterol reduction was observed with simvastatin 10 mg (32.5 ± 18.5%), while the highest mean percentage LDL reduction was obtained with rosuvastatin 40 mg (58.7 ± 18.8%). As to combined treatment, the lowest and highest mean percentage LDL cholesterol reductions were obtained with simvastatin 10 mg combined with ezetimibe (50.6 ± 24.6%) and rosuvastatin 40 mg combined with ezetimibe (71.6 ± 11.1%), respectively. Factors associated with a suboptimal response were male sex, lower age, body mass index, and baseline LDL cholesterol levels. Combined treatment was associated with less variability in LDL cholesterol reduction (OR 0.603, p < 0.001). CONCLUSION: In a real clinical setting, rosuvastatin was superior to the other statins in lowering LDL cholesterol, both as monotherapy or combined with ezetimibe. Factors associated with a suboptimal response in LDL cholesterol decline were male sex, age, body mass index, and baseline LDL cholesterol levels. Combined treatment was associated with less variability in LDL cholesterol improvement.

Bempedoic acid (BA) is a novel first-in-class oral lipid-lowering therapy. BA has been approved by the European Medicinal Agency and Food and Drug Administration and has been commercialised throughout Europe since the end of 2020 as an add-on therapy in patients at high/very-high cardiovascular risk that are not at LDL-C goals with current lipid-lowering treatments. Recently, Italian lipid management experts gathered to discuss several open questions on BA characteristics and BArelated practical clinical issues. The panel permitted collection of its opinions in a ten Q&A format. AIM: The aim of this viewpoint is to discuss and answer several open questions on BA characteristics and BA-related practical clinical issues. DATA SYNTHESIS: The data includes main phase III studies, subanalysis and meta-analysis on BA. CONCLUSIONS: The panel permitted collection of its opinions in a ten Q&A format.

BACKGROUND: Although potent lipid-lowering therapies are available, patients commonly fall short of recommended low-density lipoprotein cholesterol (LDL-C) levels. The aim of this study was to examine the relationship between familial hypercholesterolemia (FH) and elevated lipoprotein(a) [Lp(a)] and LDL-C goal attainment, as well as the prevalence and severity of coronary artery disease (CAD). Moreover, we characterized patients failing to meet recommended LDL-C goals. METHODS: We performed a cross-sectional analysis in a cohort of patients undergoing cardiac catheterization. Clinical FH was determined by the Dutch Clinical Lipid Network Score, and Lp(a) ≥ 50 mg/dL (≈ 107 nmol/L) was considered elevated. RESULTS: A total of 838 participants were included. Overall, the prevalence of CAD was 72%, and 62% received lipid-lowering treatment. The prevalence of clinical FH (probable and definite FH) was 4%, and 19% had elevated Lp(a) levels. With 35%, LDL-C goal attainment was generally poor. Among the participants with clinical FH, none reached their LDL-C target. Among patients with elevated Lp(a), LDL-C target achievement was only 28%. The prevalence and severity of CAD were higher in participants with clinical FH (86% prevalence) and elevated Lp(a) (80% prevalence). CONCLUSION: Most participants failed to meet their individual LDL-C goals according to the ESC 2016 and 2019 guidelines. In particular, high-risk patients with clinical FH or elevated Lp(a) rarely met their target for LDL-C. The identification of these patients and more intense treatment approaches are crucial for the improvement of CAD primary and secondary prevention.

Proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors significantly reduce low-density lipoprotein cholesterol (LDL-C) and improve the prognosis of patients with acute coronary syndrome (ACS). However, the feasibility and safety of early application of PCSK9 inhibitors on the basis of statins combined with ezetimibe to strengthen lipid lowering in extremely high-risk coronary heart disease populations are still unknown.This study was a prospective, randomized controlled study. A total of 136 patients with extremely high-risk ACS with LDL-C ≥ 3.0 mmol/L after percutaneous coronary intervention (PCI) treatment were randomly assigned 1:1 to the control group (atorvastatin 40 mg/day and ezetimibe 10 mg/day) or the evolocumab group (evolocumab 140 mg every 2 weeks combined with atorvastatin 40 mg/day and ezetimibe 10 mg/day). We compared the blood lipid profiles, major adverse cardiovascular events (MACEs), and adverse reactions. MACEs included cardiogenic death, nonfatal myocardial infarction, nonfatal stroke, and readmission due to angina. Adverse reactions included allergies, myalgia, poor blood glucose control, and liver damage.Within 1 month, the average level of LDL-C in the evolocumab group decreased from 3.54 to 0.57 mmol/L and that in the control group decreased from 3.52 to 1.26 mmol/L. The LDL-C compliance (< 1.0 mmol/L) rate was significantly increased in the evolocumab group compared with the control group (82.35% versus 22.06%, P < 0.01). The average level of lipoprotein (a) (Lp (a) ) in the control group increased by 9.94 ± 51.93% from baseline after treatment, but evolocumab reduced the Lp (a) level (-38.84 ± 32.40%). Additionally, evolocumab further reduced the levels of apolipoprotein B/A1 (-70.56 ± 22.38% versus -51.29 ± 18.14%), cholesterol (-54.76 ± 18.10% versus -41.16 ± 18.14%), and apolipoprotein B (-66.47 ± 26.89% versus -46.78 ± 24.12%) compared with those in the control group, all P < 0.01. The blood lipid levels of both control and evolocumab groups stabilized after 1 month. During the 3-month follow-up, the incidence of MACEs after PCI was lower in the evolocumab group than in the control group (8.82% versus 24.59%, P = 0.015), and evolocumab combined with statins and ezetimibe did not increase the occurrence of adverse reactions (13.24% versus 11.48%, P = 0.762).In patients with extremely high-risk ACS with high levels of LDL-C, adding evolocumab to their treatment regimen as early as possible may enhance lipid lowering, increase the patient's LDL-C compliance rate in the short term, and improve cardiovascular prognosis but will not increase adverse reactions.

BACKGROUND AND AIMS: Cardiovascular risk in heterozygous familial hypercholesterolaemia (HeFH) is driven by LDL cholesterol levels. Since lipid response to statin therapy presents individual variation, this study aimed to compare mean LDL and non-HDL cholesterol reductions and their variability achieved with different types and doses of the most frequently prescribed statins. METHODS AND RESULTS: Among primary hypercholesterolaemia cases on the Spanish Arteriosclerosis Society registry, 2894 with probable/definite HeFH and complete information on drug therapy and lipid profile were included. LDL cholesterol reduction ranged from 30.2 ± 17.0% with simvastatin 10 mg to 48.2 ± 14.7% with rosuvastatin 40 mg. After the addition of ezetimibe, an additional 26, 24, 21 and 24% reduction in LDL cholesterol levels was obtained for rosuvastatin, 5, 10, 20 and 40 mg, respectively. Subjects with definite HeFH and a confirmed genetic mutation had a more discrete LDL cholesterol reduction compared to definite HeFH subjects with no genetic mutation. A suboptimal response (<15% or <30% reduction in LDL cholesterol levels, respectively with low-/moderate-intensity and high-intensity statin therapy) was observed in 13.5% and, respectively, 20.3% of the subjects. CONCLUSION: According to the LDL cholesterol reduction in HeFH patients, the ranking for more to less potent statins was rosuvastatin, atorvastatin and simvastatin; however, at maximum dosage, atorvastatin and rosuvastatin were nearly equivalent. HeFH subjects with positive genetic diagnosis had a lower lipid-lowering response. Approximately 1 in 5 patients on high-intensity statin therapy presented a suboptimal response.

Hyperlipidemia is correlated with a series of health problems. Notably, aside from its established role in promoting cardiovascular morbidity and mortality, hyperlipidemia has also been considered for modulating the risk and the severity of multiple metabolic disorders. According to the results of epidemiologic investigations, several certain circulating lipoprotein species are correlated with the prevalence of diabetic retinopathy, suggesting that the physiological and pathological role of these lipoproteins is analogous to that observed in cardiovascular diseases. Furthermore, the lipid-lowering treatments, particularly using statin and fibrate, have been demonstrated to ameliorate diabetic retinopathy. Thereby, current focus is shifting towards implementing the protective strategies of diabetic retinopathy and elucidating the potential underlying mechanisms. However, it is worth noting that the relationship between major serum cholesterol species and the development of diabetic retinopathy, published by other studies, was inconsistent and overall modest, revealing the relationship is still not clarified. In this review, the current understanding of hyperlipidemia in pathogenesis of diabetic retinopathy was summarized and the novel insights into the potential mechanisms whereby hyperlipidemia modulates diabetic retinopathy were put forward.

BACKGROUND: Inflammation may contribute to the high cardiovascular risk in diabetes mellitus (DM) and chronic kidney disease (CKD). Monocyte chemoattractant protein-1 (MCP-1) facilitates the recruitment of monocytes into atherosclerotic lesions and is involved in diabetic nephropathy. Interferon gamma (IFNγ) is important in atherosclerosis and increases the synthesis of chemokines including MCP-1. Lipid-lowering treatment (LLT) with statins may have anti-inflammatory effects, and ezetimibe cotreatment provides additional cholesterol lowering. METHODS: After a placebo run-in period, the effects of simvastatin alone (S) or simvastatin + ezetimibe (S+E) were compared in a randomized, double-blind, cross-over study on inflammatory parameters. Eighteen DM patients with estimated glomerular filtration rate (eGFR) 15-59 mL/min × 1·73 m(2) (CKD stages 3-4) (DM-CKD) and 21 DM patients with eGFR > 75 mL/min (DM only) were included. RESULTS: At baseline, monocyte chemoattractant protein 1 (MCP-1) (P = 0·03), IFNγ (P = 0·02), tumour necrosis factor-α (TNFα) (P < 0·01) and soluble vascular adhesion molecule (sVCAM) (P = 0·001) levels were elevated in DM-CKD compared with DM-only patients. LLT with S and S+E reduced MCP-1 levels (P < 0·01 by anova) and IFNγ levels (P < 0·01) in DM-CKD patients but not in DM-only patients. Reductions were most pronounced with the combination treatment. CONCLUSIONS: DM patients with CKD stages 3-4 had increased inflammatory activity compared with DM patients with normal GFR. Lipid-lowering treatment decreased the levels of MCP-1 and IFNγ in DM patients with concomitant CKD, which may be beneficial with regard to the progression of both atherosclerosis and diabetic nephropathy.

Familial combined hyperlipidemia (FCH) is a frequent disorder associated with premature coronary artery disease. It is transmitted in an autosomal dominant manner, although there is not a unique gene involved. The diagnosis is performed using clinical criteria, and variability in lipid phenotype and family history of hyperlipidemia are necessaries. Frequently, the disorder is associated with type2 diabetes mellitus, arterial hypertension and central obesity. Patients with FCH are considered as high cardiovascular risk and the lipid target is an LDL-cholesterol <100mg/dL, and <70mg/dL if cardiovascular disease or type 2 diabetes are present. Patients with FCH require lipid lowering treatment using potent statins and sometimes, combined lipid-lowering treatment. Identification and management of other cardiovascular risk factors as type 2 diabetes and hypertension are fundamental to reduce cardiovascular disease burden. This document gives recommendations for the diagnosis and global treatment of patients with FCH directed to specialists and general practitioners.

BACKGROUND AND AIMS: Proper prescription and high adherence to intensive lipid lowering drugs (LLD) in patients with coronary heart disease (CHD) are crucial and strongly recommended. The aim of this study is to investigate long-term treatment patterns and adherence to LLD following hospitalization for a CHD event. METHODS: Patients admitted to two Norwegian hospitals with a CHD event from 2011 to 2014 (N = 1094) attended clinical examination and completed a questionnaire, median 16 months later. Clinical data were linked to pharmacy dispensing data from 2010 to 2020. The proportions using high-intensity statin therapy (atorvastatin 40/80 mg or rosuvastatin 20/40 mg) and non-statin LLD after the CHD event were assessed. Adherence was evaluated by proportion of days covered (PDC) and gaps in treatment. RESULTS: Median age at hospitalization was 63 (IQR 12) years, 21 % were female. Altogether, 1054 patients (96 %) were discharged with a statin prescription, while treatment was dispensed in 85 % within the following 90 days. During median 8 (SD 2.5) years follow-up, the proportion using high-intensity statin therapy ranged 62-68 %, whereas the use of ezetimibe increased from 4 to 26 %. PDC <0.8 was found in 22 % of statin users and 26 % of ezetimibe users. The proportions with a treatment gap exceeding 180 days were 22 % for statins and 28 % for ezetimibe. Smoking at hospitalization and negative affectivity were significantly associated with reduced statin adherence, regardless of adherence measure. CONCLUSIONS: In this long-term follow-up of patients with CHD, less than 70 % used high-intensity statin therapy with only small changes over time, and only 25 % used additional treatment with ezetimibe. We identified factors associated with reduced statin adherence that may be target for interventions.

BACKGROUND: Heterozygous familial hypercholesterolemia (HeFH) predisposes to premature cardiovascular diseases. Since 2015, the European Atherosclerosis Society has advocated initiation of statins at 8-10 years of age and a low-density lipoprotein cholesterol (LDL-C) target of <135 mg/dL. Longitudinal data from large databases on pharmacological management of pediatric HeFH are lacking. OBJECTIVE: Here, we describe treatment patterns and LDL-C goal attainment in pediatric HeFH using longitudinal real-world data. METHODS: This was a retrospective and prospective multicenter cohort study (2015-2021) of children with HeFH, diagnosed genetically or clinically, aged <18 years, and followed up in the National French Registry of FH (REFERCHOL). Data on the study population as well as treatment patterns and outcomes are summarized as mean±SD. RESULTS: We analyzed the data of 674 HeFH children (age at last visit: 13.1 ± 3.6 years; 82.0 % ≥10 years; 52.5 % females) who were followed up for a mean of 2.8 ± 3.5 years. Initiation of lipid-lowering therapy was on average at 11.8 ± 3.0 years of age for a duration of 2.5 ± 2.8 years. At the last visit, among patients eligible for treatment (573), 36 % were not treated, 57.1 % received statins alone, 6.4 % statins with ezetimibe, and 0.2 % ezetimibe alone. LDL-C was 266±51 mg/dL before treatment and 147±54 mg/dL at the last visit (-44.7 %) in treated patients. Regarding statins, 3.3 %, 65.1 %, and 31.6 % of patients received high-, moderate-, and low-intensity statins, respectively. Overall, 59 % of children on statin therapy alone and 35.1 % on bitherapy did not achieve the LDL-C goal; fewer patients in the older age group did not reach the treatment goal. CONCLUSION: Pediatric patients with FH followed up in specialist lipid clinics in France receive late treatment, undertreatment, or suboptimal treatment and half of them do not reach the therapeutic LDL-C goal. Finding a more efficient framework for linking scientific evidence to clinical practice is needed.

AIM: To evaluate the effects of lipid-lowering medications of different intensities on total, calcified, and non-calcified plaque volumes in patients undergoing serial cardiac computed tomography angiography (CCTA). METHODS: Individuals with chronic coronary syndromes from 11 centers were included in a retrospective registry. Total, calcified, and non-calcified plaque volumes were quantified and the relative difference in plaque volumes between baseline and follow-up CCTA was calculated. The intensity of lipid-lowering treatment was designated as low, moderate, or high, based on current recommendations. RESULTS: Of 216 patients (mean age 63.1 ± 9.7 years), undergoing serial CCTA (median timespan = 824.5 [IQR = 463.0-1323.0] days), 89 (41.2%) received no or low-intensity lipid-lowering medications, and 80 (37.0%) and 47 (21.8%) moderate- and high-intensity lipid-lowering agents, respectively. Progression of total and non-calcified plaque was attenuated in patients on moderate-/high- versus those on no/low-intensity treatment and arrested in patients treated with high-intensity statins or PCSK9 inhibitors (p < 0.001). Halted increase of non-calcified plaque was associated with LDL-cholesterol reduction (p < 0.001), whereas calcified plaque mass and Agatston score increased irrespective of the lipid-lowering treatment (p = NS). The intensity of lipid-lowering therapy robustly predicted attenuation of non-calcified plaque progression as a function of the time duration between the two CCTA scans, and this was independent of age and cardiovascular risk factors (HR = 3.83, 95% CI = 1.81-8.05, p < 0.001). CONCLUSION: The LOCATE multi-center observational study shows that progression of non-calcified plaques, which have been previously described as precursors of acute coronary syndromes, can be attenuated with moderate-intensity, and arrested with high-intensity lipid-lowering therapy.

RESUMEN
INTRODUCTION AND OBJECTIVES: Lipoprotein (a) [Lp(a)] concentration influences serum low-density lipoprotein cholesterol (LDL-C) levels. How it influences the achievement of LDL-C targets established in the guidelines is not well studied. Our aim was to know the prevalence of elevated Lp(a) levels in patients with coronary artery disease, and to assess its influence on the achievement of LDL-C targets. METHOD: We conducted a cross-sectional study in a cardiology department in Spain. A total of 870 patients with stable coronary artery disease had their lipid profile determined, including Lp(a). Patients were stratified into 2 groups according to Lp(a)>50mg/dL and Lp(a)≤50mg/dL. The association of Lp(a)>50mg/dL with achievement of LDL-C targets was assessed by logistic regression analysis. RESULTS: The prevalence of Lp(a)>50mg/dL was 30.8%. Patients with Lp(a)>50mg/dL had higher baseline (142.30±47.54 vs. 130.47±40.75mg/dL; p=0.0001) and current (72.91±26.44 vs. 64.72±25.30mg/dL; p=0.0001), despite the fact that they were treated with more high-potency statins (77.2 vs. 70.9%; p=0.058) and more combination lipid-lowering therapy (37.7 vs. 25.7%; p=0.001). The proportion of patients achieving target LDL-C was lower in those with Lp(a)>50mg/dL. Independent predictors of having elevated Lp(a) levels>50mg/dL were the use of high-potency statins (OR 1.5; 95% CI 1.08-2.14), combination lipid-lowering therapy with ezetimibe (OR 2.0; 95% CI 1.45-2.73) and failure to achieve a LDL-C ≤55mg/dL (OR 2.3; 95% CI 1.63-3.23). CONCLUSIONS: Elevated Lp(a) levels influence LDL-C levels and hinder the achievement of targets in patients at very high cardiovascular risk. New drugs that act directly on Lp(a) are needed in these patients.

BACKGROUND: Greece was recently reclassified from low- to medium-risk country in terms of cardiovascular disease, with 27% of cardiovascular deaths attributed to hypercholesterolemia. EMENO nationwide survey (2013-2016) assessed the epidemiology of dyslipidemia in the general population in Greece. METHODS: A random sample of adults was drawn by multistage stratified random sampling based on 2011 census. Standardized questionnaires and blood tests for total cholesterol (TC), low-density (LDL-C), and high-density lipoprotein cholesterol (HDL-C), and triglycerides were used. Hypercholesterolemia was defined as TC ≥ 240/200 mg/dL and/or the use of lipid-lowering drugs, hyper-LDL-cholesterolemia as LDL-C ≥160/130/100 mg/dL and/or the use of drugs, hypo-HDL-cholesterolemia as HDL-C <40 mg/dL, and hypertriglyceridemia as triglycerides ≥150 mg/dL. Weighted analysis was applied to adjust for study design, age/sex distribution discrepancies between sample and population and nonresponse. RESULTS: Of 6,006 individuals recruited, 4,298 were analyzed (mean [SD] age 49.2 [18.5] years, men 48.5%, BMI 28.2 [5.7] kg/m2). Mean TC, LDL-C, HDL-C, and TG were 193.9 [44.4], 118.5 [37.6], 49.1 [14.9], and 130.8 [94.4] mg/dL, respectively. The prevalence of hypercholesterolemia was 27.6/52.4% for thresholds ≥240/200 mg/dL, and of hyper-LDL-cholesterolemia was 26.3/46.7/74% for thresholds ≥160/130/100 mg/dL, with no differences between sexes. The prevalence of hypo-HDL-cholesterolemia was 27.5% (men/women 38.1/17.5%, p < 0.001) and of hypertriglyceridemia was 27.8% (men/women 32.6/23.4%, p < 0.001). Lipid-lowering drugs were used by 14.1% of the participants (men/women 12.6/15.6%, p < 0.001). CONCLUSIONS: More than 50% of adults in Greece have some type of dyslipidemia (mainly TC ≥ 200 mg/dL) and 14% are treated. Nationwide programmes are needed to manage dyslipidemia and halt the increasing rate of cardiovascular disease in Greece.
