This study aimed to characterize the distribution of Lp(a) in Japanese clinical settings and evaluate its association with CVD risk, including coronary artery disease (CAD), atherosclerotic cardiovascular disease (ASCVD), and familial hypercholesterolemia (FH).Methods: The LEAP study is a multicenter retrospective cohort analysis of 6,173 patients from six Japanese institutions. The Lp(a) values were harmonized to nmol/L using kit-specific conversion equations, enabling a consistent analysis across different immunoassays. Associations with CAD, ASCVD, chronic kidney disease (CKD), diabetes mellitus (DM), and FH were assessed. The risk thresholds were defined using a receiver operating characteristic analysis.Results: The median Lp(a) concentration was 20.88 nmol/L, with a right-skewed distribution. Elevated Lp(a) levels were significantly associated with CAD, ASCVD, CKD, and FH. In contrast, DM was related to lower Lp(a). An ROC analysis identified 25 nmol/L as a screening threshold and 125 nmol/L as a high-risk boundary. The CAD prevalence increased stepwise across these categories: 20.2% (≤ 25 nmol/L), 30.3% (25-125 nmol/L), and 39.9% (＞125 nmol/L).Conclusion: This study provides the first nmol/L-standardized Lp(a) distribution in Japanese patients and proposes provisional thresholds for clinical risk stratification.","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147838349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One anti-inflammatory effect of exercise is directly exerted on vascular endothelial cells by β-aminoisobutyric acid (BAIBA), which is released from the skeletal muscles during physical activity. The increased expression of estrogen-related receptor α (ERRα) and peroxisome proliferator-activated receptor-gamma co-activator (PGC)-1β also plays a role in these mechanisms. However, the underlying mechanisms remain unknown, and we aimed to explore the effects of PGC-1β on the endothelial function.Methods: We generated human umbilical vein endothelial cells (HUVECs) with PGC-1β knockdown using siRNA or by inducing the overexpression of PGC-1β using an adenovirus. We then examined the expression of inflammation-related genes induced by tumor necrosis factor α (TNFα) using qRT-PCR and the expression of endothelial nitric oxide synthase (eNOS) and its activation-related proteins using a western blot analysis.Results: BAIBA treatment suppressed the TNFα-induced expression of inflammation-related molecules in HUVECs. However, these protective effects were diminished following PGC-1β knockdown, which correlated with decreased levels of IκBα protein. Additionally, in PGC-1β knockdown-HUVECs, the total and phosphorylated levels of eNOS decreased along with the levels of active AMP-activated protein kinase (AMPK) and protein kinase B (Akt). Conversely, the overexpression of PGC-1β in HUVECs resulted in the opposite effect.Conclusion: These results suggest that BAIBA exerts various protective effects on vascular endothelial cells through the PGC-1β-NFκB and PGC-1β-AMPK-Akt-eNOS axes.","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":"619-631"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146018172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This extremely increased risk of CVD death reflects the coexistence of multiple traditional and nontraditional risk factors. The present narrative review considers two distinct steps: first, the occurrence of a CVD event, and second, death resulting from an inability to recover from the CVD event. Patients undergoing hemodialysis are at an increased risk for both of these steps, accounting for the dramatically higher risk of CVD death in this population. High risk for the second step-death following a CVD event-may be driven by conditions called decreased physical resilience and increased frailty. Studies of patients on hemodialysis show that predictors for death at this stage include key components of malnutrition-inflammation-atherosclerosis syndrome-also called the malnutrition-inflammation-complex-syndrome or protein-energy wasting-such as lower body mass index, lower serum albumin, and higher C-reactive protein. Other important contributors include higher age, longer dialysis duration, diabetic kidney disease, phosphate, calcium, serum calcification propensity (T50), and insulin-like growth factor 1 levels. Notably, some of these factors also predict death following infection, suggesting that the risk predictors for the second step are shared between CVD and infection. Recognizing these steps may facilitate prevention and greater preparedness for CVD, infection, and other stressful events among patients with CKD.","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":"521-537"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147354975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achilles tendon thickness (ATT) has been associated with the severity of coronary artery disease (CAD) in FH. However, its relevance in non-FH remains unclear. Therefore, we assessed the relationship between ATT and CAD severity in patients with acute coronary syndrome (ACS) without FH.Methods: A total of 194 patients (mean age: 69.1±11.9 years) with ACS without FH were retrospectively investigated and divided into two groups: single-vessel disease (SVD) or multivessel disease (MVD). ATT was measured using ultrasonography (US-ATT) and radiography (Xp-ATT). The association between ATT and CAD severity was evaluated.Results: Of the total, 107 patients (55.2%) had SVD, and 87 (44.8%) had MVD. Mean US-ATT and Xp-ATT values were 5.0±0.6 mm and 6.4±1.2 mm, respectively. ATT was significantly greater in the MVD group than in the SVD group (US-ATT: 5.2 mm vs. 4.8 mm, p＜0.01; Xp-ATT: 6.6 mm vs. 6.1 mm, p = 0.01) and correlated with the SYNTAX score (US-ATT: r = 0.30, p＜0.01; Xp-ATT: r = 0.19, p = 0.02). Multivariable analysis identified US-ATT as an independent predictor of MVD (odds ratio: 2.71; 95% confidence interval: 1.46-5.01; p＜0.01).Conclusion: In patients with ACS without FH, ATT was significantly associated with CAD severity. This suggests that ATT, particularly US-ATT, may serve as a practical, non-invasive marker for cardiovascular risk stratification.","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":"578-588"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145827700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
