Summary: The study shows that vascular smooth muscle cells (VSMCs) undergo a phenotypic switch when exposed to a combination of hypertensive pressure and matrix compliance, which are prevalent during atherosclerosis. The molecular mechanism involves the regulation of the actin cytoskeleton through cofilin via distinct pathways.

Summary: This study demonstrates the important role of GAG in modulating the mechanical properties of the aorta, specifically the circumferential residual stresses and radial compressive stiffness. GAG depletion leads to a decrease in the opening angle and affects the aortic ring opening angle in previously glycated tissues. Additionally, GAG depletion results in a small loss of water content and a loss of compressive deformation in the inner layer of the aorta in the AS region.

Summary: The aging population is rapidly increasing, with arterial aging leading to various age-related pathologies such as cardiovascular diseases. Age-related changes in the aortic wall affect stable circulation and lead to organ dysfunction. Remodeling of the extracellular matrix is a hallmark of aortic functional stiffening in aging.

Summary: Extracellular matrix (ECM) in the vascular wall is a dynamic structure composed of different molecules. Metalloproteases, including ADAMTS proteins, play a key role in maintaining ECM homeostasis. This review focuses on the potential role of ADAMTS proteins in the development of thoracic and abdominal aortic aneurysms, providing new insights on the involvement of the ADAMTS family in these pathologies.

Summary: Atherosclerosis is a chronic disease characterized by lipid deposition, inflammation, and impaired inflammation resolution, leading to narrowing of blood vessels, hardening, and plaque formation. Recent evidence suggests that the vascular system can be viewed as a complex homeostatic system, similar to a mini-ecosystem, consisting of the vascular microenvironment and the interaction among different types of vascular cells. By studying the cellular components in the vascular wall and their impact on vascular homeostasis, structure, function, and atherosclerosis, we can gain insights into the pathogenesis and explore vascular-stabilizing strategies to prevent cardiovascular diseases.

Summary: In patients with well-repaired CoA, there is increased proximal arterial stiffness, which correlates with diastolic function and age. The study also found an increase in Aix75 in CoA patients, possibly due to a high prevalence of associated BAV. Circulatory parameters were moderately to strongly correlated with both diastolic function and age.

Summary: Magnetic resonance imaging and computed tomography accurately assess arterial state and function, but the complexity and technical requirements of some biomarkers hinder their widespread use. This review summarizes current biomarkers related to aortic aging, their principles, required sequences and postprocessing, and their predictive values for cardiovascular events.

Summary: Children with BAV have differences in vascular function that are confined to their proximal aorta, even in normal functioning BAV. The observed differences in vascular function are likely multi-factorial, with contributions from abnormal regional flow and a potential localized primary aortopathy.

Summary: The measurement of arterial stiffness is important for predicting cardiovascular events and all-cause mortality. The influence of pulse pressure on ex vivo arterial stiffness measurements is not fully understood and requires further investigation. Changes in pulse pressure affect the overall stiffness of aortic tissue and the function of vascular smooth muscle cells, with different regions of the aorta responding differently to pulse pressure variations.

Summary: In this study, a new method was introduced to enhance the mechanical stability of cell-laden hydrogel and induce the formation of spontaneous microvascular networks. The researchers successfully implanted a 3D printed multi-branched tissue and connected it to blood vessels through direct surgical anastomosis. This work represents a significant advancement in the field of large vascularized tissue fabrication and has implications for the future treatment of organ failure.

Summary: This study developed an automated method for aortic data acquisition using ultrafast ultrasound imaging (UUI) to assess the aortic maximal rate of systolic distention (MRSD). The results showed that UUI technology can accurately track the aortic diameter and calculate the MRSD value, which is important for evaluating aortic diseases associated with bicuspid aortic valve.

Summary: Sepsis is the leading cause of death in hospital intensive care units. Recent studies have shown that variations in N-6-methyladenosine (m(6)A) levels in RNA transcripts can influence inflammatory responses. Our evaluation of m(6)A profiles in rat aortic mRNAs and lncRNAs after LPS-induced sepsis revealed significant decreases in global m(6)A levels and downregulated expression of key m(6)A writer complex members. Further analysis suggested that differentially m(6)A methylated mRNAs may affect key biological processes and inflammatory responses during sepsis.

Summary: Professional societies and guideline writing committees emphasize the importance of accurate blood pressure measurement, but most regulatory authorities do not require validation for blood pressure measurement devices. This has resulted in a global proliferation of non-validated devices, which can lead to inaccurate blood pressure estimates and impact clinical diagnosis and treatment.

Summary: This study aimed to investigate the impact of adverse childhood experiences (ACE) on rates and development of multimorbidity over three decades in adulthood. The results showed that the accumulation of psychosocial and childhood health ACEs were associated with progressively higher multimorbidity scores throughout the follow-up. All three grouped ACEs were associated with greater rates of accumulation and higher multimorbidity trajectories across adulthood.

Summary: This study investigated the appropriate allometric scaling relationships between left ventricular mass (LVM) and height, total lean mass, and body surface area in healthy adolescents. The results suggest that pooled data without adjustment for sex may introduce bias in allometric scaling estimates. Clinicians should consider body size, body composition, sex, and age when assessing left ventricular mass.

Summary: Socioeconomic inequalities in cardiovascular disease persist despite overall declines in morbidity and mortality. The causality between low socioeconomic position (SEP) and CVD is still uncertain. Traditional observational, family-based, and Mendelian randomization studies support the causal influence of low SEP on CVD, while quasi-experimental and experimental studies have mixed and limited results. More research is needed to understand the causal relationship and inform policy.

Summary: This study aimed to examine the relationship between CVD risk factors and exercise blood pressure (BP), and to identify the most strongly related risk factors. The results showed that many CVD risk factors are associated with exercise BP, mostly through indirect effects via clinic BP. Clinic BP, body composition, and fitness were found to be the most strongly associated with exercise BP.

Summary: This review aims to investigate the similarities in microvascular disease between HFpEF and CSVD, while also evaluating the diagnostic techniques using magnetic resonance imaging (MRI) for both conditions. By comparing these two conditions, potential opportunities to enhance the understanding of both HFpEF and CSVD can be identified.
