AI Article Synopsis
- The study investigates the relationship between E-selectin and ICAM-1 levels, biomarkers vital for endothelial function, and cardiac health in young adults, particularly focusing on its effects on heart function as they age.
- Higher levels of these biomarkers were found to correlate with factors like race, smoking, and obesity at the 7-year mark, which suggests a composite risk for poorer heart function later on.
- Ultimately, the research indicates that elevated E-selectin and ICAM-1 levels, particularly from Years 7 to 15, may lead to worse left ventricular systolic function in midlife, but did not significantly affect diastolic function.
Article Abstract
Background: E-selectin and intercellular adhesion molecule (ICAM)-1 are biomarkers of endothelial activation, which has been implicated in the pathogenesis of heart failure (HF) with preserved ejection fraction (HFpEF). However, the temporal associations between E-selectin and ICAM-1 with subclinical cardiac dysfunction are unclear.
Objectives: This study sought to assess the longitudinal associations of E-selectin and ICAM-1 with subclinical alterations in cardiac function.
Methods: In the Coronary Artery Disease Risk Development in Young Adults study, a cohort of black and white young adults, we evaluated the associations of E-selectin and ICAM-1, obtained at year (Y) 7 (Y7) and Y15 examinations, with cardiac function assessed at Y30 after adjustment for key covariates.
Results: Higher E-selectin (n = 1,810) and ICAM-1 (n = 1,548) at Y7 were associated with black race, smoking, hypertension, and higher body mass index. After multivariable adjustment, higher E-selectin at Y7 (β coefficient per 1 SD higher: 0.22; SE: 0.06; p < 0.001) and Y15 (β coefficient per 1 SD higher: 0.19; SE: 0.06; p = 0.002) was associated with worse left ventricular (LV) global longitudinal strain (GLS). Additionally, higher Y15 ICAM-1 (β coefficient per 1 SD higher: 0.18; SE: 0.06; p = 0.004) and its increase from Y7 to Y15 (β coefficient per 1 SD higher: 0.16; SE: 0.07; p = 0.03) were also independently associated with worse LV GLS. E-selectin and ICAM-1 partially mediated the associations between higher body mass index and black race with worse GLS. Neither E-selectin nor ICAM-1 was associated with measures of LV diastolic function after multivariable adjustment.
Conclusion: Circulating levels of E-selectin and ICAM-1 and increases in ICAM-1 over the course of young adulthood are associated with worse indices of LV systolic function in midlife. These findings suggest associations of endothelial activation with subclinical HF with preserved ejection fraction.

Background: Vascular calcification is common and progressive in patients with chronic kidney disease. However, the risk factors associated with the progression of vascular calcification in patients receiving maintenance dialysis have not been fully elucidated. Here, we aimed to evaluate vascular calcification and identify the factors associated with its progression in patients receiving maintenance hemodialysis.

Background: Studies regarding hypercoagulation in Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) patients have produced conflicting results. With a presumption that the early coagulation phase may affect the occurrence of NAION, this study aims to investigate the early coagulation markers, E-selectin and P-selectin, to determine whether these biomolecular changes play a significant role in NAION, thus potentially leading to a better clinical approach.
Methods: A cross-sectional study involving two groups of NAION subjects, a hypercoagulation group and a non-hypercoagulation group, was conducted in the Neuro-Ophthalmology Division, Department of Ophthalmology, FKUI-RSCM Kirana from October 2020 to April 2022.

Objective: Inflammation drives cardiovascular disease in rheumatoid arthritis (RA). Treatment with tofacitinib, a JAK1/JAK3 inhibitor, is associated with increased cardiovascular events in patients with RA. Here, we determined its effects on cytokine production during interactions between immune cells at the synovial and vascular levels and its impact on endothelial activation and coagulation during inflammation.

Background: A significant association between immune cells and sepsis has been suggested by observational studies. However, the precise biological mechanisms underlying this association remain unclear. Therefore, we employed a Mendelian randomization (MR) approach to investigate the causal relationship between immune cells and genetic susceptibility to sepsis, and to explore the potential mediating role of blood metabolites.
