The aim of this study was to quantify the economic impact of atherosclerosis in Portugal by estimating disease-related costs. Methods: Costs were estimated based on a prevalence approach and following a societal perspective. Three national epidemiological sources were used to estimate the prevalence of the main clinical manifestations of atherosclerosis. The annual costs of atherosclerosis included both direct costs (resource consumption) and indirect costs (impact on population productivity). These costs were estimated for 2016, based on data from the Hospital Morbidity Database, the health care database (SIARS) of the Regional Health Administration of Lisbon and Tagus Valley including real-world data from primary care, the 2014 National Health Interview Survey, and expert opinion. Results: The total cost of atherosclerosis in 2016 reached 1.9 billion euros (58% and 42% of which was direct and indirect costs, respectively). Most of the direct costs were associated with primary care (55%), followed by hospital outpatient care (27%) and hospitalizations (18%). Indirect costs were mainly driven by early exit from the labor force (91%). Conclusions: Atherosclerosis has a major economic impact, being responsible for health expenditure equivalent to 1% of Portuguese gross domestic product and 11% of current health expenditure in 2016.

Introduction and Aims: Atherogenic dyslipidemia is an important contributor to residual cardiovascular (CV) risk, but it is underdiagnosed and undertreated. This study aimed to assess the opinion of Portuguese experts to generate a consensus concerning the diagnosis and treatment of atherogenic dyslipidemia, as well as to contribute toward standardization of clinical practice in this disorder. Methods: The study consisted in the application of a questionnaire to an expert panel, following a modified Delphi methodology. Results: The majority (88.4%) of the proposed items were found to be consensual. The expert panel recognized the importance of the atherogenic dyslipidemia phenotype, the role played by low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol as risk markers and therapeutic targets, the choice of statins as first-line lipid-lowering drugs, and the value of associating statins with fenofibrate as a means to reduce residual CV risk. However, the role played by triglycerides in CV risk and the therapeutic value of fibrates lacked consensus. Taking into consideration the state of the art and the opinions expressed in this study, the scientific committee developed a treatment algorithm aimed to improve the perception and treatment of atherogenic dyslipidemia. Conclusions: The experts involved in this study were shown to be familiar with the concept and the importance of atherogenic dyslipidemia. The few situations in which a consensus could not be found were mainly related to the interpretation and/or relevance of the available evidence. Resumo: Introdução e objetivos: A dislipidemia aterogénica contribui consideravelmente para o risco residual de doença cardiovascular (DCV); não obstante, esta patologia encontra-se subdiagnosticada e submedicada. O objetivo deste estudo foi analisar a opinião dos especialistas portugueses e gerar um consenso sobre o diagnóstico e o tratamento da dislipidemia aterogénica, bem como promover a uniformização da prática clínica neste contexto. Métodos: Este estudo consistiu na aplicação de um questionário a um painel de peritos seguindo uma metodologia Delphi modificada. Resultados: A maioria dos itens (88,4%) foram consensuais. Os peritos inquiridos mostraram reconhecer a importância da dislipidemia aterogénica, o papel preponderante do colesterol de lipoproteínas de baixa densidade (c-LDL) e do colesterol total excluindo o das lipoproteínas de alta densidade (colesterol não HDL) na indicação do risco cardiovascular e na definição de objetivos terapêuticos, a eleição das estatinas como fármaco antidislipidémico de primeira linha, e a pertinência da sua associação com o fenofibrato para a redução do risco residual. Não obstante, o painel manifestou incerteza no que se refere ao papel dos triglicerídeos e ao valor terapêutico dos fibratos. Tendo como base a evidência disponível na literatura e as opiniões recolhidas neste estudo, a comissão científica elaborou um algoritmo de tratamento com o objetivo de promover a sensibilização e adequação da terapêutica a doentes com dislipidemia aterogénica. Conclusões: Os inquiridos mostraram estar familiarizados com o conceito e com a importância da dislipidemia aterogénica; as poucas situações de ausência de consenso poderão estar relacionadas com uma diferente interpretação e/ou valorização da evidência científica disponível.

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.

Among the cardiovascular risk factors, cholesterol-rich atherogenic lipoproteins play a central role in the pathogenesis of atherosclerosis. In middle-aged adults, the size of the total atherosclerotic plaque burden is influenced by both the concentration of circulating atherogenic lipoproteins and the total duration of exposure to these lipoproteins. This review describes the evidence supporting a causal link between lifelong elevations in atherogenic lipoproteins and future risk of atherosclerosis; evidence strengthened by recent epidemiological, genetic, and clinical data. By consequence, adolescence and early adulthood are a crucial time for determining later cardiovascular disease risk. Arguments showing that early optimal lipid control leads to improved outcomes will be presented and suggestions put forward for how those most at risk should be identified and managed.

Methods and results: The burden of atherosclerosis was measured in disability-adjusted life years (DALY) following the latest 2010 Global Burden of Disease (GBD) methodology. DALYs were estimated as the sum of years of life lost (YLL) with years lived with disability (YLD). The following clinical manifestations of atherosclerosis were included: ischemic heart disease (IHD) (including acute myocardial infarction (AMI), stable angina, and ischemic heart failure (IHF)), ischemic cerebrovascular disease (ICVD) and peripheral arterial disease (PAD). YLL were estimated based on all-cause mortality data for the Portuguese population and mortality due to IHD, ICVD and PAD for the year 2016 sourced from national statistics. Standard life expectancy was sourced from the GBD study. YLD corresponded to the product of the number of prevalent cases by an average disability weight (DW) for all possible combinations of disease. Prevalence data for the different clinical manifestations of atherosclerosis were sourced from epidemiological studies. DW were sourced from the published literature. In 2016, 15,123 deaths were attributable to atherosclerosis, which corresponded to 14.3% of overall mortality in mainland Portugal. DALYs totaled 260,943, 75% due to premature death (196,438 YLL) and 25% due to disability (64,505 YLD). Conclusion: Atherosclerosis entails a high disease burden to society. A large part of this burden would be avoidable if evidence-based effective and cost-effective interventions targeting known risk factors, from prevention to treatment, were implemented., This study was funded by Bayer Portugal, Lda. Funding was independent of the study outcomes.

A meeting of European experts in cardiovascular (CV) disease and lipids was convened in Paris, France, on 10 November 2014 to discuss lipid profile, and in particular atherogenic dyslipidaemia (AD), and associated CV risk. Key points that were raised and discussed during the meeting are summarised in this paper, which also accounts for further discussion and agreement on these points by the group of experts. Elevated levels of low-density lipoprotein cholesterol (LDL-c) are commonly associated with a greater CV risk than low LDL-c levels, and are routinely managed with statins. However, even for patients controlled on statins and achieving low LDL-c levels, abnormal lipid profiles observed in some patients (i.e. elevated triglyceride levels, with/without low levels of high-density lipoprotein cholesterol [HDL-c]) have been linked to the presence of a residual CV risk. Therefore, it is recommended that both triglyceride and HDL-c levels be measured, to allow for the overall CV residual risk to be adequately managed. Favourable safety and clinical data support the combination of statins with other lipid-lowering agents, such as fenofibrate. Patients who have elevated triglyceride levels plus low levels of HDL-c are most likely to achieve clinical benefit from fenofibrate-statin combination therapy. In these patients with AD, achieving target non-HDL-c levels should be a key focus of CV risk management, and the use of non-HDL-c was advocated to provide a better measure of CV risk than LDL-c levels.
