The 2018 American Heart Association/American College of Cardiology/Multi-Society (AHA/ACC/MS) Guideline on the Management of Blood Cholesterol and the 2019 European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) Guidelines for the Management of Dyslipidemias: Lipid Modification to Reduce Cardiovascular Risk, that were recently released by the United States and Europe, provide new recommendations for the management of blood lipid levels based on the latest evidence. Despite many common points, there are several differences in the recommendations, including the definition of very-high-risk patient category, the recommendations for some categories of patients, such as those with diabetes, familial hypercholesterolemia, chronic kidney disease, and aged patients, and the use of ezetimibe and PCSK9 inhibitors. These differences suggest that multiple approaches can be used to manage lipid abnormalities in the context of cardiovascular risk reduction.

The evidence of the causal role of low-density lipoprotein cholesterol in the development of atherosclerotic cardiovascular disease is well-established. The clearly identified common position of the European guidelines proclaims necessity to decrease LDL-C concentrations based on a proper risk stratification. However, current worldwide situation with the lipid management still demonstrates inadequate dyslipidemia control, that is probably related to a healthcare system issues. As the need to standardize and implement approaches following the guidelines into clinical practice remains a challenge, the EAS initiates the Lipid Clinics Network project, aiming to provide a structure to establish uniform EU-wide standards of diagnosis, management and treatment of patients with lipid disorders, based on the ESC/EAS Guidelines on management of dyslipidaemias.

The availability of efficient lipid-lowering drugs has substantially reduced the incidence and mortality for cardiovascular disease (CVD). Despite that, CVD still represents a major cause of death and disability; efforts are thus required to prevent this disease, since reducing the established CV risk factors may slow or prevent the onset of cardiovascular events. Current guidelines recommend a healthier lifestyle for all CV risk categories, as it may have a beneficial impact on several risk factors; in individuals with a low-to-moderate hypercholesterolemia, which are not eligible for a pharmacological approach and are not far from the cholesterol target recommended for their risk category, functional foods or nutraceuticals may be considered as supplement to reduce their CV risk status. Of note, counseling and lifestyle intervention in people at moderate CV risk represents a major issue for both preventing a further risk increase and reducing the need for drugs. Studies on general populations have clearly indicated that lifestyle interventions translate into a clinical benefit, with reduction of the incidence of myocardial infarction and the risk of developing type 2 diabetes.

Post-acute coronary syndrome (ACS) patients are at very high risk for recurrent events and mortality, despite the availability of effective pharmacological approaches. In 2018, the ACS EuroPath Survey, performed in collaboration with 555 European cardiologists, identified a sub-optimal LDL-C management in post-ACS patients. Based on these premises, the ACS EuroPath II project led to the development of a self-assessment tool to improve lipid management in these very high risk patients, taking into consideration the new 2019 ESC/EAS guidelines. This tool is built in 3 sections. The first is a questionnaire to assess the lipid management practice from the acute phase up to 12 months of follow-up. The main topics covered in this section relate to 1) acute phase (lipid management of ACS patients during hospitalization; 2) discharge (lipid management at discharge, with focus on follow-up plan); 3) follow-up (lipid management at the time of first and subsequent follow-ups); 4) referral pathway for definitive lipid management care of post-ACS patients; 5) evaluation of the achieved goal at 6 months to 1 year and key implications. The second section is a brief report to position the results against other European Union clinical practice and European guidelines. The last section allows the physician to evaluate and consider the implementation of one or more strategies, successfully developed in leading European centers, in order to optimize their own clinical practice.

To estimate the prevalence of cardiovascular (CV) disease and CV risk factors among Polish patients. A nationwide cross-sectional study, LIPIDOGRAM2015, was carried out in Poland in the 4th quarter of 2015 and 1st and 2nd quarters of 2016; 438 primary care physicians enrolled 13,724 adult patients that sought medical care in primary health care practices. Nearly 19% of men and approximately 12% of women had cardiovascular disease (CVD). Over 60% of the recruited patients had hypertension (HTN), >80% had dyslipidaemia and <15% of patients were diagnosed with diabetes (DM). All of these disorders were more frequent in men. In 80% of patients the waist circumference exceed norm for the European population. Less than half of the patients were current smokers or had smoked in the past. Patients with CVD had significantly higher blood pressure and glucose levels but lower low density lipoprotein-cholesterol level. The prevalence of CVD and CV risk factors among patients in Poland is high. CVD is more common in men than in women. The most common CV risk factors are excess waist circumference, dyslipidaemia and HTN. Family physicians should conduct activities to prevent, diagnose early and treat CVD in the primary health care population.

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 of <55mg/dL or even <40mg/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.

Post-acute coronary syndrome (ACS) patients are at very high cardiovascular risk. Despite current guidelines strongly recommend to reduce LDL-C levels and initiation of high-intensity statins as early as possible in patients admitted with an ACS, less than half of ACS patients receive a high intensity statin, and a high percentage of has LDL-C well above the goal despite therapy. There are multiple reasons for that, including physician lack of guideline adherence, patient lack of compliance with treatment, and lack of standardized procedures. Furthermore, although the prevalence of familial hypercholesterolemia is higher among patients with ACS, this condition remains poorly estimated. To fill these gaps, some European countries have launched local initiatives for the in-hospital and post-discharge ACS patient lipid management. It appears that ensuring optimal therapy during hospitalization and dedicated follow-up protocols results in a significant improvement of lipid levels in these very high risk patients, which may translate into a reduced risk of recurrent future events.

The metabolic syndrome (MetS) has become one of the most important clinical issues in the cardiovascular field for this decade because of the marked increase in cardiovascular (CV) risk associated with a clustering of risk factors. The aim of the current study was to evaluate the relationship between MetS and its components and cardiovascular disease (CVD). This population-based cross-sectional study was based on data from two studies carried out in Russia (ESSE-RF) and Italy (PLIC). One sample from each cohort was selected, matching individuals by sex and age. A comparison between samples of MetS components distribution and CV risk, according to SCORE chart, has been conducted. A total of 609 individuals (mean [SD] age 55 [8] years, about 39% males) for each cohort were selected. Almost half of PLIC cohort participants belonged to the moderate CV risk group (47% vs 27%), while in ESSE-RF cohort a relatively higher prevalence of individuals classified in the high and very high risk group was observed (19% vs 11%, 21% vs 6%, respectively). Overall, 43% of ESSE-RF participants were diagnosed with MetS, compared with the 27% of PLIC members (the difference in prevalence becomes 37% vs 21%, considering a more conservative cut-off for waist circumference). Both cohorts showed a trend towards the increase of MetS components moving from the lowest to the highest CV risk class, with a high prevalence of patients with four or five MetS determinants allocated in the high/very high CV risk group. Developing effective public health strategies for the prevention, detection and treatment of MetS should be an urgent priority to reduce the burden of CVD, not only in subjects at high/very high CV risk, but also in those characterized by a lower risk, as even rare CV events that come from low risk group bring a tangible burden to healthcare systems.

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. 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. 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 >70mg/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 <100mg/dL raised from 23% to 72%. Among acute cases, 44 were admitted with a diagnosis of familial hypercholesterolemia (FH); only 18% of the remaining patients were screened for FH. Contemporary lipid management of very high CV risk patients is sub-optimal despite available treatments. Greater efforts are warranted to optimize cardiovascular prevention.

Familial hypercholesterolemia (FH) is a common genetic disorder of lipid metabolism, still underdiagnosed and undertreated in the general population. Pathology registers could play a crucial role in the creation of a comprehensive and integrated global approach to cover all aspects of this disease. Systematic data collection of patients affected by FH has increased dramatically worldwide in the past few years. Moreover, results from registers already established for the longest time showed their potentialities in the implementation of the knowledge of FH, comparing country-specific approaches and providing real-world data about identification, management and treatment of FH individuals in the clinical practice. The potential fields of research through registers are related to the deepening of the genetic basis of disease, the study of genotype-phenotype correlation, the local adaption and implementation of diagnostic algorithms, the comparison of pharmacological approaches and treatment gaps in real-life clinical practice, the evaluation of specific subpopulations, and the identification of factors modifying cardiovascular disease risk. Registers could become also a valid resource for other rare dyslipidaemias, contributing towards the evidence-based enhancement in the worldwide care of uncommon diseases.
