Purpose Of Review: The exposome refers to the total environmental exposures a person encounters throughout life, and its relationship with human health is increasingly studied. This non-systematic review focuses on recent research investigating the effects of environmental factors-such as air pollution, noise, greenspace, neighborhood walkability, and metallic pollutants-on atherosclerosis, a major cause of cardiovascular disease.

Recent Findings: Studies show that long-term exposure to airborne particulate matter can impair endothelial function and elevate adhesion molecule levels, leading to vascular damage.

Background: Implementation of semaglutide weight loss therapy has been challenging due to drug supply and cost, underscoring a need to identify those who derive the greatest absolute benefit.

Objectives: Allocation of semaglutide was modeled according to coronary artery calcium (CAC) among individuals without diabetes or established atherosclerotic cardiovascular disease (CVD).

Methods: In this analysis, 3,129 participants in the MESA (Multi-Ethnic Study of Atherosclerosis) without diabetes or clinical CVD met body mass index criteria for semaglutide and underwent CAC scoring on noncontrast cardiac computed tomography.

Mitochondrial dysfunction is an important driver of neurodegeneration and synaptic abnormalities in Alzheimer's disease (AD). Amyloid beta (Aβ) in mitochondria leads to increased reactive oxygen species (ROS) production, resulting in a vicious cycle of oxidative stress in coordination with a defective electron transport chain (ETC), decreasing ATP production. AD neurons exhibit impaired mitochondrial dynamics, evidenced by fusion and fission imbalances, increased fragmentation, and deficient mitochondrial biogenesis, contributing to fewer mitochondria in brains of AD patients.

Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapies due to their self-renewal and differentiation capabilities. Pathological microenvironments expose MSCs to senescence-inducing factors such as reactive oxygen species (ROS), resulting in MSC functional decline and loss of stemness. Oxidative stress leads to mitochondrial dysfunction, a hallmark of senescence, and is prevalent in aging tissues characterized by elevated ROS levels.

Reducing low-density lipoprotein cholesterol (LDL-C) levels has been shown to reduce the risk of developing atherosclerotic cardiovascular disease (ASCVD). Statins are the foundation of LDL-C lowering therapy with other non-statin agents used in circumstances where goal LDL-C levels are not reached or owing to intolerance to adverse effects of statins. In 2003, the discovery of the role of the proprotein convertase subtilisin/kexin type 9 (PCSK9) system in promoting elevated LDL-C levels led to new avenues of drug development to achieve target LDL-C.

Article Synopsis
  • Cardiovascular diseases (CVD) are a major health issue in the North Africa and Middle East region, with an overall increase in incidence despite a slight decline in age-standardized rates from 1990 to 2021.
  • Research showed that men face higher rates of CVD-related incidence, prevalence, and deaths, with ischemic heart disease and stroke being leading causes of disability-adjusted life years (DALYs).
  • Key risk factors include high blood pressure, unhealthy diets, and high LDL cholesterol, with areas affected by conflict experiencing even greater health burdens, highlighting the need for focused health interventions.

Social determinants of health (SDoH) significantly impacts health outcomes and disparities. While the Centers for Medicare and Medicaid Services has mandated hospitals to collect standardized SDoH data, existing tools lack key elements. This systematic review identified 78 studies and 20 screening tools addressing various SDoH domains.

Article Synopsis
  • The study examined differences in echocardiographic assessments of native and bioprosthetic aortic valves between core laboratories and clinical centers, finding clinically relevant discrepancies.
  • Data was collected from the PERIGON trial, which involved patients undergoing surgical aortic valve replacement, and involved comparing echocardiographic results from centers to independent analysis by a core lab.
  • Results showed that while some continuous measurements had high agreement (around 0.90), there were notable variances, particularly in left ventricular outflow tract area and stroke volume, indicating the need for standardized evaluation practices.

Article Synopsis
  • This study investigated the effect of mitral stenosis (MS) on outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) with modern balloon-expandable valves, using data from over 327,000 patients across multiple centers.
  • It was found that while patients with severe MS initially had worse outcomes, when matched for similar characteristics, their 30-day outcomes were similar to those with mild or less MS, except for a higher rate of pacemaker implantation.
  • However, by three years post-TAVR, patients with severe MS showed a significantly higher mortality rate compared to those with mild or less MS, suggesting long-term risks associated with severe MS.

  • The study focuses on the impact of tricuspid regurgitation (TR) on heart remodeling, comparing outcomes in patients treated with the TriClip device versus those receiving standard medical therapy in a randomized controlled trial.
  • Researchers utilized advanced imaging techniques, including cardiac magnetic resonance and 4D-CT, to assess heart changes at baseline, 30 days, and one year follow-ups.
  • Results showed that the TriClip significantly reduced TR volume by 70% at 30 days, leading to notable reductions in right ventricular size and area, with these improvements maintained after one year, unlike the control group.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) are associated with cardiovascular outcomes and are recommended for measurement in type 2 diabetes (T2D). However, the effects of an intensive lifestyle intervention (ILI) targeting weight loss on cardiac biomarkers and the prognostic association of changes in these biomarkers with risk of adverse cardiovascular outcomes in T2D are not well-established.

Objectives: This study sought to evaluate the effects of an ILI on cardiac biomarkers and the association of changes in cardiac biomarkers with risk of cardiovascular outcomes in T2D.

Background: The impact of mitral annular calcification (MAC) on the clinical outcomes of patients undergoing mitral transcatheter edge-to-edge repair (MTEER) remains unclear. This meta-analysis aims to evaluate the clinical outcomes of MTEER among patients with moderate to severe MAC compared to those with mild or no MAC.

Methods: We systematically searched PubMed, EMBASE, and Cochrane CENTRAL databases through March 31st, 2024, comparing clinical outcomes of MTEER among patients with moderate/severe (MAC+) versus no/mild MAC (MAC-).

Over a decade of randomized controlled trial data demonstrate excellent outcomes with transcatheter aortic valve replacement or surgical aortic valve replacement for patients with symptomatic severe aortic stenosis regardless of surgical risk. The 2020 American College of Cardiology/American Heart Association guidelines recommend both options for low-risk AS patients aged 65 to 80 years. However, the fastest growing population of patients receiving transcatheter aortic valve replacement in the United States is <65 years old, with little data to support the practice.

Polygenic Risk Scores and Extreme Coronary Artery Calcium Phenotypes (CAC=0 and CAC≥1000) in Adults ≥75 Years Old: The ARIC Study.

Circ Cardiovasc Imaging

Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University School of Medicine, Baltimore, MD (O.D., A.C.R., Z.A.D., S.P.W., M.B.M., M.J.B.).

Article Synopsis
  • The study examines the relationship between polygenic scores for coronary heart disease (CHD) and coronary artery calcium (CAC) in adults aged 75 and older, suggesting that genetic factors may influence arterial aging beyond traditional risk factors.
  • Researchers analyzed data from 1,865 participants, finding that higher polygenic CHD risk scores were associated with significantly lower odds of having no CAC and much higher odds of having high CAC levels.
  • Each standard deviation increase in the polygenic risk score corresponded to a 78% increase in CAC scores, indicating a strong link between genetic predisposition and arterial health in older adults.
