OBJECTIVE: Familial Hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism that causes an increased risk of premature atherosclerotic cardiovascular disease (ASCVD). Although early diagnosis and treatment of FH can significantly improve the cardiovascular prognosis, this disorder is underdiagnosed and undertreated. For these reasons the Italian Society for the Study of Atherosclerosis (SISA) assembled a Consensus Panel with the task to provide guidelines for FH diagnosis and treatment.
RESULTS: Our guidelines include: i) an overview of the genetic complexity of FH and the role of candidate genes involved in LDL metabolism; ii) the prevalence of FH in the population; iii) the clinical criteria adopted for the diagnosis of FH; iv) the screening for ASCVD and the role of cardiovascular imaging techniques; v) the role of molecular diagnosis in establishing the genetic bases of the disorder; vi) the current therapeutic options in both heterozygous and homozygous FH. Treatment strategies and targets are currently based on low-density lipoprotein cholesterol (LDL-C) levels, as the prognosis of FH largely depends on the magnitude of LDL-C reduction achieved by lipid-lowering therapies. Statins with or without ezetimibe are the mainstay of treatment. Addition of novel medications like PCSK9 inhibitors, ANGPTL3 inhibitors or lomitapide in homozygous FH results in a further reduction of LDL-C levels. LDL apheresis is indicated in FH patients with inadequate response to cholesterol-lowering therapies.
CONCLUSIONS: FH is a common, treatable genetic disorder and, although our understanding of this disease has improved, many challenges still remain with regard to its identification and management.

BACKGROUND: A study was designed to investigate whether the coronary artery disease polygenic risk score (CAD-PRS) may guide lipid-lowering treatment initiation as well as deferral in primary prevention beyond established clinical risk scores.
RESULTS: Participants were 311 799 individuals from the UK Biobank free of atherosclerotic cardiovascular disease, diabetes, chronic kidney disease, and lipid-lowering treatment at baseline. Participants were categorized as statin indicated, statin indication unclear, or statin not indicated as defined by the European and US guidelines on statin use. For a median of 11.9 (11.2-12.6) years, 8196 major coronary events developed. CAD-PRS added to European-Systematic Coronary Risk Evaluation 2 (European-SCORE2) and US-Pooled Cohort Equation (US-PCE) identified 18% and 12% of statin-indication-unclear individuals whose risk of major coronary events were the same as or higher than the average risk of statin-indicated individuals and 16% and 12% of statin-indicated individuals whose major coronary event risks were the same as or lower than the average risk of statin-indication-unclear individuals. For major coronary and atherosclerotic cardiovascular disease events, CAD-PRS improved C-statistics greater among statin-indicated or statin-indication-unclear than statin-not-indicated individuals. For atherosclerotic cardiovascular disease events, CAD-PRS added to the European evaluation and US equation resulted in a net reclassification improvement of 13.6% (95% CI, 11.8-15.5) and 14.7% (95% CI, 13.1-16.3) among statin-indicated, 10.8% (95% CI, 9.6-12.0) and 15.3% (95% CI, 13.2-17.5) among statin-indication-unclear, and 0.9% (95% CI, 0.6-1.3) and 3.6% (95% CI, 3.0-4.2) among statin-not-indicated individuals.
CONCLUSIONS: CAD-PRS may guide statin initiation as well as deferral among statin-indication-unclear or statin-indicated individuals as defined by the European and US guidelines. CAD-PRS had little clinical utility among statin-not-indicated individuals.

OBJECTIVE: In 2016, the Lipid Association of India (LAI) developed a cardiovascular risk assessment algorithm and defined low-density lipoprotein cholesterol (LDL-C) goals for prevention of atherosclerotic cardiovascular disease (ASCVD) in Indians. The recent refinements in the role of various risk factors and subclinical atherosclerosis in prediction of ASCVD risk necessitated updating the risk algorithm and treatment goals.
METHODS: The LAI core committee held twenty-one meetings and webinars from June 2022 to July 2023 with experts across India and critically reviewed the latest evidence regarding the strategies for ASCVD risk prediction and the benefits and modalities for intensive lipid lowering. Based on the expert consensus and extensive review of published data, consensus statement IV was commissioned.
RESULTS: The young age of onset and a more aggressive nature of ASCVD in Indians necessitates emphasis on lifetime ASCVD risk instead of the conventional 10-year risk. It also demands early institution of aggressive preventive measures to protect the young population prior to development of ASCVD events. Wide availability and low cost of statins in India enable implementation of effective LDL-C-lowering therapy in individuals at high risk of ASCVD. Subjects with any evidence of subclinical atherosclerosis are likely to benefit the most from early aggressive interventions.
CONCLUSIONS: This document presents the updated risk stratification and treatment algorithm and describes the rationale for each modification. The intent of these updated recommendations is to modernize management of dyslipidemia in Indian patients with the goal of reducing the epidemic of ASCVD among Indians in Asia and worldwide.

Atherosclerotic cardiovascular disease (ASCVD) remains the main cause of death worldwide, and thus its prevention, early diagnosis and treatment is of paramount importance. Dyslipidemia represents a major ASCVD risk factor that should be adequately managed at different clinical settings. 2023 guidelines of the Hellenic Atherosclerosis Society focus on the assessment of ASCVD risk, laboratory evaluation of dyslipidemias, new and emerging lipid-lowering drugs, as well as diagnosis and treatment of lipid disorders in women, the elderly and in patients with familial hypercholesterolemia, acute coronary syndromes, heart failure, stroke, chronic kidney disease, diabetes, autoimmune diseases, and non-alcoholic fatty liver disease. Statin intolerance is also discussed.

BACKGROUND: The 2021 Canadian Cardiovascular Society (CCS) guidelines recommend intensive low-density lipoprotein cholesterol (LDL-C) reduction for patients with atherosclerotic cardiovascular disease (ASCVD). For patients above LDL-C threshold on maximally tolerated statins, adding ezetimibe and/or a proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) is recommended. This population-based, real-world study examined cardiovascular (CV) events in patients with ASCVD who are on statins and above current guideline threshold LDL-C levels.
METHODS: Using administrative health data in Alberta, Canada, we identified patients with myocardial infarction (MI), ischemic stroke (IS), or peripheral artery disease with LDL-C > 1.8 mmol/L on statins between April 1, 2010 and March 31, 2016. Exploratory subgroups included very high-risk patients with ASCVD shown to derive the most benefit from PCSK9i intensification as identified by the CCS guidelines, including those with acute coronary syndrome (ACS) or recent MI. Frequencies and rates of individual and composite CV events (primary outcome: MI, IS, hospitalization for unstable angina, coronary revascularization, cardiovascular death; secondary outcome: MI, IS, CV death) were calculated over follow-up.
RESULTS: The study included 32,984 patients with a mean (standard deviation) follow-up of 40.8 (21.0) months. Overall, 17.7% and 15.6% experienced a primary and secondary outcome, respectively, with rates of 5.58 and 4.83 per 100 patient-years, respectively. CV death and MI were the most common events. Subgroups with recurrent MI and comorbid diabetes exhibited higher CV event rates (23.6% and 22.2% had a primary outcome, respectively). Rates of CV events were notably high in patients with ACS or recent MI (49.4% and 54.0% had a primary outcome, respectively).
CONCLUSIONS: This real-world study confirms that statin-treated high-risk patients with ASCVD and above-threshold LDL-C levels have substantial incidence of recurrent CV events. These findings reinforce the opportunity for lipid-lowering therapy intensification in high-risk patients to levels below guideline-recommended threshold in order to reduce CV risk.

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality and morbidity in individuals with type 2 diabetes mellitus (T2DM). Accordingly, several scientific societies have released clinical practice guidelines to assist health professionals in ASCVD risk management in patients with T2DM. However, some recommendations differ from each other, contributing to uncertainty about the optimal clinical management of patients with T2DM and established ASCVD or at high risk for ASCVD. Thus, the purpose of this paper is to discuss recent evidence-based guidelines on ASCVD risk stratification and prevention in patients with T2DM, in terms of disparities and similarities. To close the gap between different guidelines, a multidisciplinary approach involving general practitioners, endocrinologists, and cardiologists may enhance the coordination of diagnosis, therapy, and long-term follow-up of ASCVD in patients with T2DM.

Background and objective Diabetes is a major risk factor for the development of cardiovascular diseases. To tackle this issue, guidelines have emphasized the use of cardioprotective antihyperglycemic agents [glucagon-like peptide-1 receptor agonists (GLP1-RAs) and sodium-glucose co-transporter-2 (SGLT2) inhibitors] among type 2 diabetic patients at high risk of/with established atherosclerotic cardiovascular disease (ASCVD) or heart failure to curb morbidity and mortality in such individuals. The aim of this study was to assess physicians\' adherence to the American Diabetes Association\'s (ADA) recommendations on the use of cardioprotective antihyperglycemic agents among such patients.  Methods This study involved a retrospective records review of physicians\' treatment plans for all type 2 diabetic patients aged 18 years and older and attending outpatient clinics from the year 2019 to 2022 at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, who (a) were at high risk of/with established ASCVD as defined by the American Diabetes Association (ADA) or (b) had heart failure with reduced ejection fraction (HFrEF) and required cardioprotective antihyperglycemic agents. Results We reviewed physicians\' treatment plans for 202 type 2 diabetic patients in this study. All patients were either at high risk of or had established ASCVD. In addition, 36 (17.8%) of these patients had HFrEF. Although all patients were candidates for cardioprotective antihyperglycemic agents, only 56.9% of them received treatment as recommended by the ADA guidelines. Conclusion Despite being suitable candidates for cardioprotective antihyperglycemics, a significant number of patients were not treated based on the ADA guidelines, and this demonstrates a lack of adherence to the guidelines by physicians.

OBJECTIVE:  The goals of this quality improvement project are to assess the BRIDGE Student-Run Free Clinic\'s adherence to the 2019 American College of Cardiology (ACC)/American Heart Association (AHA) Guideline on the Primary Prevention of Cardiovascular Disease and to compare our rate of statin prescription to the national average and to uninsured groups.
METHODS: A quality improvement project of 205 patients qualified by initial inclusion criteria at a student-run free healthcare clinic. Socio-demographic information, clinical measures associated with cardiovascular risk, and documentation regarding statin prescription at the follow-up visit after a patient\'s first lipid panel were abstracted from medical records. Descriptive statistics were calculated on the sample (proportions, means), and the proportion of patients eligible for statin treatment was determined.
RESULTS: Of 58 patients eligible by guidelines to receive statins, 29 received a statin (50%) at their follow-up visit. Patients with clinical atherosclerotic cardiovascular disease (ASCVD) were more likely to receive statin therapy (83.3%) compared to other groups. Patients who were prescribed a statin were older, had higher total cholesterol, higher low-density lipoprotein (LDL), higher systolic blood pressure, and had higher ASCVD risk. Patients receiving statins were also more likely to be male or have a history of either hypertension, diabetes, or clinical ASCVD.
CONCLUSIONS: Patients with established ASCVD had high rates of statin prescription. Following the first lipid panel, clinicians prescribed statins to approximately 50% of eligible patients. Although this proportion is below the national average for insured patients, it is higher than the national average for uninsured patients and represents a relatively high proportion of eligible patients within the examined time frame.

In view of the consolidating evidence on the causal role of Lp(a) in cardiovascular disease, the Italian Society for the Study of Atherosclerosis (SISA) has assembled a consensus on Lp(a) genetics and epidemiology, together with recommendations for its measurement and current and emerging therapeutic approaches to reduce its plasma levels. Data on the Italian population are also provided.
Lp(a) is constituted by one apo(a) molecule and a lipoprotein closely resembling to a low-density lipoprotein (LDL). Its similarity with an LDL, together with its ability to carry oxidized phospholipids are considered the two main features making Lp(a) harmful for cardiovascular health. Plasma Lp(a) concentrations vary over about 1000 folds in humans and are genetically determined, thus they are quite stable in any individual. Mendelian Randomization studies have suggested a causal role of Lp(a) in atherosclerotic cardiovascular disease (ASCVD) and aortic valve stenosis and observational studies indicate a linear direct correlation between cardiovascular disease and Lp(a) plasma levels. Lp(a) measurement is strongly recommended once in a patient\'s lifetime, particularly in FH subjects, but also as part of the initial lipid screening to assess cardiovascular risk. The apo(a) size polymorphism represents a challenge for Lp(a) measurement in plasma, but new strategies are overcoming these difficulties. A reduction of Lp(a) levels can be currently attained only by plasma apheresis and, moderately, with PCSK9 inhibitor treatment.
Awaiting the approval of selective Lp(a)-lowering drugs, an intensive management of the other risk factors for individuals with elevated Lp(a) levels is strongly recommended.

UNASSIGNED: The impact of the stepwise implementation of the 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) treatment algorithm on low-density lipoprotein cholesterol (LDL-C) goal attainment was simulated in patients from the DA VINCI study.
UNASSIGNED: Monte Carlo simulation was used to evaluate treatment optimisation scenarios, based on a patient\'s risk category: statin intensification (step 1), addition of ezetimibe (step 2), and addition of a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor (step 3). Residual cardiovascular risk and predicted relative and absolute risk reduction (RRR and ARR) in cardiovascular events were assessed.
UNASSIGNED: In DA VINCI, 2482 patients did not achieve their 2019 ESC/EAS LDL-C goals and were included in the simulation. In patients without atherosclerotic cardiovascular disease (ASCVD) (n = 962), 27.0% (n = 259) and 57.0% (n = 548) are likely to achieve their LDL-C goals at step 1 and step 2, respectively. Of those at very high risk without ASCVD (n = 74), 88.1% (n = 65) are likely to achieve their LDL-C goals at step 3. In patients with ASCVD (n = 1520), 12.0% (n = 183), 42.1% (n = 641) and 93.2% (n = 1416) are likely to achieve their LDL-C goals at steps 1, 2 and 3, respectively. In patients with and without ASCVD, treatment optimisation may result in mean simulated RRR of 24.0% and 17.7%, respectively, and ARR of 8.1% and 2.6%, respectively.
UNASSIGNED: Most patients at high cardiovascular risk are unlikely to achieve LDL-C goals through statin optimisation and ezetimibe, and will require a PCSK9 inhibitor, leading to greater reduction in cardiovascular risk.
UNASSIGNED: Amgen.
