Current Atherosclerosis Reports最新文献

Purpose of review: To summarize selected late-breaking science on cardiovascular disease (CVD) prevention presented at the 2024 European Society of Cardiology (ESC) Congress.

Recent findings: Key studies from the 2024 ESC Congress highlight advances in (CVD) management. Apolipoprotein A-1 infusions reduced risk in acute myocardial infarction patients with high LDL cholesterol. Plozasiran cut triglycerides and apolipoprotein C-III levels, lowering pancreatitis risk. A 14-year study linked smoking among youth to cardiac abnormalities. Baseline hsCRP, LDL-C, and Lp(a) were strong predictors of 30-year outcomes in women. Alternative LDL-lowering strategies matched high-intensity statins in effectiveness of LDL-C lowering and reduced diabetes risk. Early combination lipid lowering therapy improved outcomes post-myocardial infarction. Nordic and Mediterranean diets were linked to lower atherosclerotic CVD risk. The findings from the 2024 ESC Congress highlight significant advancements in CVD prevention, including novel lipid-lowering therapies, biomarker-based risk prediction, and lifestyle interventions. These studies underscore the importance of early and personalized treatment strategies to mitigate long-term cardiovascular risk.

Purpose of the review: This review is intended to serve as guidance for care providers working with children who have dyslipidemia and exhibit picky eating behaviors.

Recent findings: Picky eating behaviors in children can be very stressful for caregivers and children alike, even if they may not reach clinical significance. In the setting of lipid disorder treatment, picky eating can present an even greater challenge, since many of the foods considered most heart-healthy are not often considered "kid-friendly". Care providers should validate caregivers' concerns, screen for picky eating and be prepared to provide guidance to parents and a referral to a specialist, if needed. This review contains an itemized list of points to focus on with families and additional resources.

Purpose of the review: This review discusses the molecular mechanisms involved in the immuno-pathogenesis of atherosclerosis, the pleiotropic anti-inflammatory effects of approved cardiovascular therapies and the available evidence on immunomodulatory therapies for atherosclerotic cardiovascular disease (ACVD). We highlight the importance of clinical and translational research in identifying molecular mechanisms and discovering new therapeutic targets.

Recent findings: The CANTOS (Canakinumab Anti-Inflammatory Thrombosis Outcomes Study) trial was the first to demonstrate a reduction in cardiovascular (CV) risk with anti-inflammatory therapy, irrespective of serum lipid levels. ACVD is the leading cause of death worldwide. Although targeting principal risk factors significantly reduces CV risk, residual risk remains unaddressed. The immunological mechanisms underlying atherosclerosis represent attractive therapeutic targets. Several commonly used and non-primarily anti-inflammatory drugs (i.e. SGLT2i, and PCSK9i) exhibit pleiotropic properties. Otherwise, recent trials have investigated the blockade of primarily inflammatory compounds, trying to lower the residual risk via low-dose IL-2, PTPN22 and CD31 pathway modulation. In the era of precision medicine, modern approaches may explore new pharmacological targets, identify new markers of vascular inflammation, and evaluate therapeutic responses.

Purpose of review: This paper reviews the existing literature on statin-related myopathy in children and adolescents, to inform development of a practical management approach.

Recent findings: Reports of statin treatment in the pediatric population revealed no evidence of muscle pathology, with asymptomatic elevation of creatine kinase(CK) levels and symptoms of muscle pain without CK elevation seen equally in subjects and controls in RCTs. By contrast, rare cases of rhabdomyolysis have now been documented in statin-treated children; this serious problem had never been previously reported. Statin-induced myopathy is rare in childhood so routine monitoring of CK levels is unnecessary in asymptomatic patients, reserved for those with muscle pain. Rare case reports of rhabdomyolysis in statin-treated children and adolescents suggest that parent and patient education on symptoms of adverse statin effects should include immediate physician contact with the appearance of dark urine, with or without muscle pain.

Purpose of the review: This review examines the pivotal role of monoclonal antibodies against PCSK9 in lipid-lowering therapy, emphasizing their biological and clinical impact.

Recent findings: Randomized controlled trials have validated that PCSK9 monoclonal antibodies (Mabs) effectively reduce LDL-c levels by approximately 50%, even when added to maximal statin therapy. They moreover produce a notable 15-20% relative decrease in major cardiovascular events, with a greater reduction among high-risk patients and no evidence for serious adverse effects, assuaging previous concerns. This review highlights the benefits of PCSK9 Mabs in high cardiovascular risk patients. Despite their efficacy and safety, these therapies are hindered by limited access, and require broader integration into clinical practice to optimize therapeutic outcomes.

Purpose of review: Pediatric healthcare providers have increasingly become aware of the need for timely and informative transition of adolescents and young adults with chronic medical conditions such as diabetes and cystic fibrosis. However, there is paucity of published data on the importance of and most effective way to transition youth with lipid disorders who are at increased risk of premature cardiovascular disease.

Recent findings: Evidence shows that atherosclerosis begins at a young age. However, there are no guidelines on the transition of adolescents and young adults with dyslipidemia. In addition, there are conflicting guidelines for lipid management in children versus adults, despite advances in medical pharmacotherapies for dyslipidemia. The lack of guidelines for transition and discordant recommendations for management of this vulnerable population places young adults at-risk for worsening of their underlying disease, and premature cardiovascular events.

Purpose of the review: The purpose of this review is to evaluate the current state of knowledge regarding the technical challenges associated with the Post-Acquisition Fat Attenuation Index (PFAI). By examining the limitations and gaps in the current methodologies, this review aims to provide a comprehensive understanding of how various factors impact the accuracy and reliability of PFAI measurements.

Recent findings: PFAI correlates with plaque instability, as inflammation in coronary plaque alters surrounding adipose tissue composition, increasing its water content and reducing lipid content, which is detectable via cardiac CT as increased attenuation. Recent studies have demonstrated PFA's prognostic value, with elevated levels linked to higher risks of cardiac events and plaque instability. A 2022 meta-analysis confirmed its association with major adverse cardiac events. Machine learning algorithms incorporating PFA and additional imaging features have further enhanced risk prediction beyond traditional metrics. Pericoronary fat attenuation is a promising marker for assessing coronary inflammation and could be useful in predicting plaque development, rupture, and monitoring treatment response, though further prospective studies and technical standardization are needed to fully establish its clinical benefits.

Purpose of review: Climate change is profoundly impacting cardiovascular disease through rising temperatures, more extreme weather events, and worsening air pollution. This review analyzes how these factors affect cardiovascular health.

Recent findings: Extreme heat and cold cause physiological changes, including increasing the risk of blood clots, faster heart rates, and inflammation. Air pollution and wildfire smoke lead to oxidative stress and systemic inflammation, leading to heightened cardiovascular risk. Extreme weather disrupts healthcare access, complicating chronic condition management and negatively impacts people from lower socioeconomic communities. Climate-related stressors also affect mental health, which in turn impacts cardiovascular health. Long-term changes, such as food insecurity and migration, further strain heart health due to poor diets and psychological stress. Cardiologists must understand these risks to better support and treat patients in our changing climate.

Purpose of review: The objective of this narrative review is to summarize data from recently published prospective observational studies that analyze the association between circulating interleukin-6 (IL-6) levels and cardiovascular clinical or imaging endpoints.

Recent findings: Higher levels of IL-6 are associated with a higher risk of cardiovascular death, major adverse cardiovascular events, myocardial infarction, stroke, peripheral artery disease, and heart failure. Imaging studies have also shown an association between IL-6 and carotid intima-media thickness progression, carotid plaque progression, severity, and vulnerability. These observations have been consistent across a wide range of study populations and after adjusting for traditional and emerging risk factors including high-sensitivity C-reactive protein. Robust epidemiologic evidence supports IL-6 as a central mediator of cardiovascular risk along with human genetic studies and mechanistic experiments. Ongoing clinical studies are testing the therapeutic hypothesis of IL-6 inhibition in patients with atherosclerotic cardiovascular disease or heart failure.

Purpose of review: Although statin therapy is well established to prevent atherosclerotic vascular disease (ASCVD) events in adults 40 to 75 years of age, it is less clear whether older adults benefit from statin therapy. The purpose of this review is to summarize the current evidence and guidelines on statin use for primary and secondary prevention in older patients.

Recent findings: Moderate to high intensity statin therapy decreases cardiovascular event rates in older patients with or at risk for ASCVD. Cardiac biomarkers and coronary calcium scoring can identify older patients at higher ASCVD risk who may benefit from statin therapy. Age alone should not be a deterrent to statin therapy in older patients. The decision to initiate statin therapy should occur after a patient to clinician discussion based on the patient's overall ASCVD risk and weighed against other clinical factors that influence the patient's life expectancy and quality of life.
