OBJECTIVE: GALIPEMIAS is a study designed to establish the prevalence of familial dyslipidemia in the general population of Galicia. The objective of the present study was to assess the prevalence of atherogenic dyslipidemia (AD), its relationship with other cardiovascular risk (CVR) factors, and the degree of lipid control.
METHODS: Cross-sectional study carried out in the general population over 18 years of age residing in Galicia and with a health card from the Galician Health Service (N=1,000). Selection of the sample by means of random sampling by conglomerates. The AD prevalence adjusted for age and sex and the related variables were analyzed.
RESULTS: The prevalence of AD adjusted for age and sex was 6.6% (95% CI: 5.0-8.3%). Arterial hypertension, altered basal glycemia, type 2 diabetes mellitus and cardiovascular disease were more frequent in subjects with AD than in the rest of the population. 47.5% of the subjects with AD had a high or very high CVR. Lipid-lowering drugs were received by 38.9% (30.5% statins) of the participants with AD (46.1% of those with high and 71.4% of those with very high CVR). 25.4% of the subjects with AD had target LDL-c levels, all of them with low or moderate CVR.
CONCLUSIONS: The prevalence of AD in the general adult population of Galicia is not negligible, and it was related to several CVR factors and cardiovascular disease. Despite this, this lipid alteration was underdiagnosed and undertreated.

The incorporation of a healthy diet, regular physical exercise and smoking cessation are the initial measures to reduce cardiovascular risk in patients with atherogenic dyslipidemia. In these patients, the nutritional quality of their diet should be improved, replacing foods with a greater atherogenic effect for others with a healthier effect. There is strong evidence that plant-based dietary patterns, low in saturated fatty acids, cholesterol and sodium, with a high content of fiber, potassium and unsaturated fatty acids, are beneficial and reduce the expression of cardiovascular risk factors. This document focuses on the role of nutrition in the prevention and treatment of atherogenic dyslipidemia, providing current evidence to serve as a tool for health professionals in its clinical management. To facilitate the reading of these recommendations, they are presented in a user-friendly table format, with a hierarchy of different levels of evidence.

BACKGROUND: SmartLab 2.0 is an innovative concept of multidisciplinary collaboration between the clinical laboratory and the diabetes day unit that was born with the aim of identifying patients at high cardiovascular risk who require priority attention, such as patients with atherogenic dyslipidemia, in order to create a cardiovascular prevention strategy.
OBJECTIVE: Implementation in the Laboratory Information System (LIS) of an automated biochemical algorithm for the identification of patients with atherogenic dyslipidemia in routine analyses and priority referral to the diabetes day unit.
METHODS: The algorithm designed in the SIL was: HBA1c>9.3 +TG>150mg/dl +HDLc<40mg/dl +LDL/ApoB<1.3. A comment was inserted alerting the requesting physician of the diagnosis of atherogenic dyslipidemia and priority referral was made from the laboratory to the diabetes day unit in the necessary cases.
RESULTS: In the 1-year period, a total of 899 patients with HBA1c>7 and atherogenic dyslipidemia criteria were identified. Of these, 203 patients from primary care with HbA1c>9.3 were referred to the diabetes day hospital.
CONCLUSIONS: Reinforcement of cardiovascular prevention is necessary at all levels. The clinical laboratory should play a fundamental role in the diagnosis of dyslipidemias. Early detection of patients at high cardiovascular risk is essential and collaboration between the different clinical units is fundamental to guarantee patient safety.

Apolipoprotein C-III (apoC-III) is a small protein that is predominantly synthesized in the liver and mainly resides at the surface of triglyceride-rich lipoproteins. Its expression is upregulated by glucose and reduced by insulin, with enhanced apoC-III promoting hypertriglyceridemia and inflammation in vascular cells. The protein is also elevated in patients with diabetes, suggesting that enhanced apoC-III levels might contribute to the development of type 2 diabetes mellitus. The present review focuses on the key mechanisms by which apoC-III could promote type 2 diabetes mellitus, including exacerbation of insulin resistance in skeletal muscle, activation of β-cell apoptosis, promotion of weight gain through its effects on white adipose tissue and hypothalamus, and attenuation of the beneficial effects of high-density lipoproteins on glucose metabolism. Therapeutic strategies aimed at reducing apoC-III levels may not only reduce hypertriglyceridemia but also might improve insulin resistance, thus delaying the development of type 2 diabetes mellitus.

The importance of overall lipid control in cardiovascular prevention is reviewed. Several studies and meta-analyses show that the control of LDL cholesterol (LDL-C) still maintains a high cardiovascular risk, which is related to the presence of triglyceride-rich lipoproteins, and therefore with an increase in plasma triglycerides and the values of apolipoprotein B (apoB) containing these lipoproteins. The importance of this relationship is due to the change in the lipid profile of our population in recent years. This is related to the increase in obesity and insulin resistance, and is called atherogenic dyslipidaemia. Thus, hypertriglyceridaemia should be considered a cardiovascular risk factor, especially when the desirable objectives of LDL-C have been achieved. The indications for treatment with fibrates in primary and secondary prevention, using the medical evidence-based recommendations, are described, along with its importance in the reduction of cardiovascular risk. Finally, the established indications of the combined statin-fibrate treatment are presented, always after changes in lifestyle.

OBJECTIVE: To describe the management of atherogenic dyslipidemia (AD) in routine clinical practice in the Primary Care (PC) setting in Spain.
METHODS: Observational, descriptive, cross-sectional study based on a structured questionnaire designed for this study and addressed to PC physicians. The questionnaire content was based on a literature review and was validated by 3 experts in AD.
RESULTS: A total of 1029 PC physicians participated in the study. 96.99% indicated that AD is determinant for cardiovascular risk, even if LDL-C levels are appropriate. 88.43% evaluated residual cardiovascular risk in their clinical practice, however, only 27.89% of them evaluated it in secondary prevention. Regarding diagnosis, 82.22% reported that TC, TG, HDL-C and non-HDL-C are essential measures when evaluating AD. Almost all physicians reported that they can request fractionated cholesterol to assess HDL-C and LDL-C, however 3.69% could not. Physicians (95.63%) considered that the first step in AD treatment should be diet, regular exercise, smoking cessation and pharmaceutical treatment, if necessary. 19.1% agreed partially or completely that gemfibrozil is the most suitable fibrate to associate with statins. 74.83% completely agreed that fenofibrate is the most suitable fibrate to combine with statins.
CONCLUSIONS: Physicians have access to general Spanish guidelines and recommendations associated with AD management, however, it is necessary to continue rising awareness about the importance of early detection and optimal control of AD to reduce patients\' cardiovascular risk.

OBJECTIVE: The \"DAT-AP\" (from the Spanish, \"Dislipemia ATerogénica en Atención Primaria\", for Atherogenic Dyslipidaemia in Primary Care) study objective is to determine to what extent published consensus guidelines for the diagnostic and therapeutic management of AD are used in the primary care setting, and to evaluate the approach of the participating physicians towards the detection, diagnosis, and treatment of AD.
METHODS: This is descriptive, cross-sectional, multicentre study performed between January and May 2015 in primary care centres throughout Spain. Study data were collected in 2 independent blocks, the first addressing theoretical aspects of AD and the second, practical aspects (clinical cases) RESULTS: The theoretical part is in the process of publication. This manuscript depicts the clinical cases block. Although study participants showed good knowledge of the subject, the high prevalence of this disease requires an additional effort to optimise detection and treatment, with the implementation of appropriate lifestyle interventions and the prescription of the best treatment.

This document has discussed clinical approaches to managing cardiovascular risk in clinical practice, with special focus on residual cardiovascular risk associated with lipid abnormalities, especially atherogenic dyslipidaemia (AD). A simplified definition of AD was proposed to enhance understanding of this condition, its prevalence and its impact on cardiovascular risk. AD can be defined by high fasting triglyceride levels (≥2.3mmol/L / ≥200mg/dL) and low high-density lipoprotein cholesterol (HDL-c) levels (≤1,0 / 40 and ≤1,3mmol/L / 50mg/dL in men and women, respectively) in statin-treated patients at high cardiovascular risk. The use of a single marker for the diagnosis and treatment of AD, such as non-HDL-c, was advocated. Interventions including lifestyle optimization and low density lipoprotein (LDL) lowering therapy with statins (±ezetimibe) are recommended by experts. Treatment of residual AD can be performed with the addition of fenofibrate, since it can improve the complete lipoprotein profile and reduce the risk of cardiovascular events in patients with AD. Others clinical condictions in which fenofibrate may be prescribed include patients with very high TGs (≥5.6mmol/L / 500mg/dL), patients who are intolerant or resistant to statins, and patients with AD and at high cardiovascular risk. The fenofibrate-statin combination was considered by the experts to benefit from a favorable benefit-risk profile. In conclusion, cardiovascular experts adopt a multifaceted approach to the prevention of atherosclerotic cardiovascular disease, with lifestyle optimization, LDL-lowering therapy and treatment of AD with fenofibrate routinely used to help reduce a patient\'s overall cardiovascular risk.

Positioning document and summary of recommendations recently published by the Working Group on Atherogenic Dyslipemia of the Spanish Society of Arteriosclerosis and by the European Society of Arteriosclerosis.

OBJECTIVE: Atherogenic dyslipidaemia is underdiagnosed, undertreated, and under-controlled. The aim of the present study was to assess the positioning of clinical guidelines as regards atherogenic dyslipidaemia.
METHODS: The major clinical guidelines of scientific societies or official agencies issued between January 1, 2012 and March 31, 2015 were collected from the MEDLINE database. High-density lipoprotein (HDL) cholesterol, triglycerides, atherogenic dyslipidaemia, non-HDL cholesterol, and apolipoprotein (apo) B were gathered from the 10 selected guidelines, and it was assessed whether these parameters were considered a cardiovascular risk factor, a therapeutic target, or proposed a pharmacological strategy.
RESULTS: American guidelines, except the National Lipid Association (NLA), do not consider HDL cholesterol and triglycerides in cardiovascular prevention. The NLA emphasises the relevance of atherogenic dyslipidaemia. The Canadian guidelines introduced non-HDL cholesterol and ApoB as alternative targets, and proposes non-statin treatment in the presence of low HDL cholesterol and hypertriglyceridaemia. The International Atherosclerosis Society (IAS) and National Institute for Health and Care Excellence (NICE) guidelines promote the importance of non-HDL cholesterol. European, Brazilian and Japanese guidelines highlight HDL cholesterol and triglycerides, but with the limitation that the main evidence comes from sub-analysis of clinical studies.
CONCLUSIONS: The clinical guidelines analysed do not consider, or unconvincingly address, the importance of atherogenic dyslipidaemia.
