However, studies exploring the effect of metabolic indices on hs-CRP while controlling for confounding variables adequately in middle-aged adults are limited. Using Wave 5 public-use biomarkers data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we examined the impact of various metabolic indices on hs-CRP in adults aged 32-42, controlling for eight allergic and infectious factors that may elevate hs-CRP levels. We used multiple linear regression analysis to determine which factors predict hs-CRP levels after the log transformation of the dependent variable. The total number of participants was N = 1839 (weighted N = 1,390,763), with a mean age of 38.1 (SD = 2.0) and 46.4% having obesity. Among the controlled variables, recent surgery was the only confounder to significantly predict increased hs-CRP levels [ P = 0.029; exponentiated estimate (EE) = 1.61; 95% confidence interval (Cl), 1.31-1.91]. Notably, current smoking and altered low-density lipoprotein levels did not show a significant association with hs-CRP levels ( P > 0.05). However, a significant increase in hs-CRP levels was observed in females compared with males ( P < 0.001; EE = 1.43; 95% Cl, 1.35-1.51). Similar findings were noted for diabetic HbA1c levels ( P = 0.001; EE = 1.6; 95% CI, 1.42-1.78), high waist circumference ( P = 0.015; EE = 1.25; 95% CI, 1.15-1.35), and stage 3 obesity ( P = 0.006; EE = 7.62; 95% CI, 2.86-12.38). Although not statistically significant, hs-CRP levels exhibited a gradual increase with rising body mass index after controlling for other variables. These findings will improve the clinical application of hs-CRP in predicting coronary artery disease, especially in younger adults.</p>","PeriodicalId":35914,"journal":{"name":"Critical Pathways in Cardiology","volume":" ","pages":"e0378"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11968444/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142476566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nearly 30% of Emergency Department (ED) patients with chest pain have undiagnosed and/or unmanaged HLD, putting them at an increased risk of ASCVD. Although safe and effective HLD treatments exist, the ED traditionally focuses on acute care and does not offer preventive cardiovascular care services. This represents a large, missed opportunity to improve cardiovascular health for the millions of Americans evaluated in the ED each year who are not receiving appropriate preventive care in the outpatient setting. The goals of this study are to determine the efficacy of novel ED-initiated preventive care on lowering cholesterol while also informing our understanding of patient adherence and implementation determinants of ED-initiated preventive cardiovascular care.</p><p><strong>Methods: </strong>We will use a randomized, controlled, parallel group trial of 130 ED patients being evaluated for acute coronary syndrome (ACS) at a single site.

Patients will be randomized with equal probability to EMERALD (Emergency Medicine Cardiovascular Risk Assessment for Lipid Disorders) or usual care. Patients in the EMERALD arm will be started on a statin and referred for 30-day follow-up with cardiology or primary care, depending on 10-year ASCVD risk level.

Random-effects meta-analyses were used.</p><p><strong>Results: </strong>A total of 10 prospective trials were identified that enrolled 42,253 individuals who presented with an acute coronary syndrome. Our analysis found that heparin when compared to bivalirudin was associated with an increased risk of trial-based definition of major bleeding [relative risk (RR): 1.68, 95% confidence interval (CI): 1.29-2.20], nonaccess site complications (RR: 4.6, 95% CI: 1.75-12.09), thrombolysis in myocardial infarction major bleeding (RR: 1.70, 95% CI: 1.20-2.41), major bleeding risks (RR: 1.87, 95% CI: 1.49-2.36), cardiovascular disease death (RR: 1.26, 95% CI: 1.02-1.57), and thrombocytopenia (RR: 1.67, 95% CI: 1.07-2.62). There were no statistically significant differences between heparin and bivalirudin for all-cause mortality, major adverse cardiovascular event, stroke, reinfarction, target vessel revascularization, and acute or stent thrombosis.</p><p><strong>Conclusions: </strong>The present meta-analysis demonstrates bivalirudin reduces major bleeding when used for anticoagulation during PCI in patients with acute coronary syndromes and is not associated with an increased risk of stent thrombosis or major adverse cardiovascular event.</p>","PeriodicalId":35914,"journal":{"name":"Critical Pathways in Cardiology","volume":" ","pages":"e0372"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141972014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
