In Japan, the MetS diagnostic criteria established in 2005 require abdominal obesity as a mandatory component, with WC cutoff values of 85 cm for men and 90 cm for women. These criteria are also applied in the national Specific Health Checkup and Specific Health Guidance programs to identify individuals at a high risk of CVD. However, the scientific basis and clinical implications of these thresholds remain controversial.This review summarizes the epidemiological evidence on WC cutoff values in the Japanese population and their relevance to CVD risk. A literature search of PubMed and Ichushi-Web identified studies examining WC thresholds in relation to visceral fat accumulation, clustering of cardiometabolic risk factors, and incident CVD. The evidence was organized into four themes: (1) WC cutoffs based on visceral fat area, (2) prediction of cardiometabolic risk factor clustering, (3) the association between WC and incident CVD, and (4) associations between MetS definitions and CVD risk.Available evidence suggests that the WC thresholds corresponding to visceral fat accumulation and cardiometabolic risk clustering are generally lower than the current Japanese criterion for women. Prospective studies examining WC alone have reported inconsistent associations with incident CVD, particularly among women. Overall, the evidence suggests that CVD risk stratification frameworks requiring abdominal obesity based on WC thresholds may have limitations. Future screening strategies in Japan may benefit from greater emphasis on clustering and the overall burden of cardiometabolic risk factors.</p>","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":"993-1014"},"PeriodicalIF":3.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13448046/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147963511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inhibition of ACL suppresses acetyl-CoA production, leading to reduced cholesterol synthesis and increased hepatic expression of LDL receptors, which lowers circulating LDL-C. Clinical trials have demonstrated an approximately 20% reduction in LDL-C when bempedoic acid is used in combination with statins. To offer a new perspective on the underlying mechanism, we reviewed the literature examining the LDL-C-lowering effects of bempedoic acid based on Michaelis-Menten kinetics. This framework helps explain why adding bempedoic acid to statin therapy may result in a synergistic increase in LDL-C reduction, greater than from increasing the statin dose alone. In animal studies, reductions observed in both hepatic and plasma triglyceride (TG) levels have been attributed to suppressed fatty acid synthesis due to decreased acetyl-CoA availability following ACL inhibition. Additionally, bempedoic acid has been shown to lower high-sensitivity C-reactive protein (hs-CRP) and inflammatory cytokines, suggesting potential anti-inflammatory and anti-lipotoxic effects. These findings support broader metabolic benefits of bempedoic acid, particularly in conditions such as obesity and fatty liver with hypercholesterolemia. In this review article, we outline the synergistic effects of bempedoic acid with statins, and its potential metabolic benefits based on the mechanism of action of bempedoic acid, and discuss its prospective role in future lipid management strategies.</p>","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":"1015-1024"},"PeriodicalIF":3.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13447979/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148015708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
