We explored whether a protein risk score derived from large-scale proteomics data improves risk prediction of atrial fibrillation (AF).METHODSA total of 51 680 individuals with 1459 unique plasma protein measurements and without a history of AF were included from the UKB-PPP (UK Biobank Pharma Proteomics Project). A protein risk score was developed with lasso-penalized Cox regression from a random subset of 70% (36 176 individuals, 54.4% women, 2155 events) and was tested on the remaining 30% (15 504 individuals, 54.4% women, 910 events). The protein risk score was externally replicated with the ARIC study (Atherosclerosis Risk in Communities; 11 012 individuals, 54.8% women, 1260 events).RESULTSThe protein risk score formula developed from the UKB-PPP derivation set was composed of 165 unique plasma proteins, and 15 of them were associated with atrial remodeling. In the UKB-PPP test set, a 1-SD increase in protein risk score was associated with a hazard ratio of 2.20 (95% CI, 2.05-2.41) for incident AF. The C index for a model including CHARGE-AF (Cohorts for Heart and Aging Research in Genomic Epidemiology Atrial Fibrillation), NT-proBNP (N-terminal B-type natriuretic peptide), polygenic risk score, and protein risk score was 0.816 (95% CI, 0.802-0.829) compared with 0.771 (95% CI, 0.755-0.787) for a model including CHARGE-AF, NT-proBNP, and polygenic risk score (C-index change, 0.044 [95% CI, 0.039-0.055]). Protein risk score added to CHARGE-AF, NT-proBNP, and polygenic risk score resulted in a risk reclassification of 5.4% (95% CI, 2.9%-7.9%) with a 5-year risk threshold of 5%. In the decision curve, the predicted net benefit before and after the addition of protein risk score to a model including CHARGE-AF, NT-proBNP, and polygenic risk score was 3.8 and 5.4 per 1000 people, respectively, at a 5-year risk threshold of 5%.

Arachidonic acid (AA) is a prominent polyunsaturated fatty acid in the human body and plays an important role in various physiological and pathological conditions. AA metabolic enzymes determine AA levels; however, currently there is no comprehensive analysis of AA enzymes in cardiac I/R injury.METHODSThe profiling of AA metabolic enzymes was analyzed with the RNA sequencing transcriptome data from the mouse heart tissues with I/R injury. Cultured neonatal and adult rat ventricular myocytes, human embryonic stem cell-derived cardiomyocytes, and in vivo mouse I/R models were used to confirm the role of L-PGDS (lipocalin-type prostaglandin D2 synthase)/15d-PGJ2 in I/R injury. A biotin-tagged 15d-PGJ2 analog combined with liquid chromatography-tandem mass spectrometry was used to identify the downstream signaling of L-PGDS/15d-PGJ2.RESULTSBased on the transcriptome data and experimental validations, L-PGDS, together with its downstream metabolite 15d-PGJ2, was downregulated in cardiac tissue with I/R injury. Functionally, L-PGDS overexpression mitigates myocardial I/R injury, whereas knockdown exacerbates the damage. Supplementation of 15d-PGJ2 alleviated I/R injury. Mechanistically, 15d-PGJ2 covalently bound to the Ca2+/CaMKII (calmodulin protein kinase II) and induced lipoxidation of its cysteine 495 (CaMKII-δ9) to dampen the formation of CaMKII oligomers and alleviate its overactivation, consequently ameliorating cardiomyocyte death and cardiac injury.CONCLUSIONSOur study uncovered L-PGDS/15d-PGJ2/CaMKII signaling as a new mechanism underlying I/R-induced cardiomyocyte death. This provides new mechanistic insights and therapeutic targets for myocardial I/R injury and subsequent heart failure. We also showed that lipoxidation is a new post-translational modification type for CaMKII, deepening our understanding of the regulation of its activity.","PeriodicalId":10331,"journal":{"name":"Circulation","volume":"72 1","pages":""},"PeriodicalIF":37.8,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144103740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early treatment initiation is crucial for cardiovascular risk reduction; however, many patients do not reach LDL-C treatment goals. Inclisiran, a small interfering RNA targeting hepatic PCSK9 (proprotein convertase subtilisin/kexin type 9), is effective and well tolerated in adult patients with hyperlipidemia; however, it has not yet been studied in pediatric patients.METHODSHerein we report results of the 1-year, double-blind, placebo-controlled part of the phase 3 study ORION-13 (Study to Evaluate Efficacy and Safety of Inclisiran in Adolescents With Homozygous Familial Hypercholesterolemia) in adolescents with HoFH. This 2-part multicenter study included 13 patients ≥12 to <18 years of age with a genetic diagnosis of HoFH (excluding LDL [low-density lipoprotein] receptor [LDLR] null/null genotypes) and elevated LDL-C levels (>130 mg/dL) on maximally tolerated statin treatment, with or without other lipid-lowering therapies. Eligible patients were randomized 2:1 to receive either 300 mg of inclisiran sodium or placebo, administered on days 1, 90, and 270. The primary end point was the mean percentage change in LDL-C from baseline to day 330.RESULTSThe mean age of patients was 14.8 years, and mean baseline LDL-C was 272 mg/dL. The placebo-adjusted mean (95% CI) percentage change in LDL-C from baseline to day 330 was -33.3% (-59.2% to -7.3%). Six of 9 (66.7%) inclisiran-treated patients (versus 1 of 4 [25%] on placebo) achieved a >15% reduction in LDL-C, and 5 of 9 (55.6%) inclisiran-treated patients (versus none on placebo) achieved a >20% reduction. The placebo-adjusted mean (95% CI) percentage change in PCSK9 from baseline to day 330 was -60.2% (-79.8% to -40.7%); corresponding changes in apoB (apolipoprotein B), non-high-density lipoprotein cholesterol, and total cholesterol were -23.0%, -32.7%, and -27.8%, respectively. No serious adverse events, treatment discontinuations because of adverse events, or deaths occurred. No new safety findings were reported.CONCLUSIONSIn a 1-year randomized controlled study (part 1 of ORION-13), inclisiran was effective in lowering LDL-C in adolescents with HoFH and was well tolerated. These results support inclisiran as a potentially useful addition for the treatment of adolescents with HoFH and a minimum of LDLR residual activity.REGISTRATIONURL: https://www.clinicaltrials.gov; Unique identifier: NCT04659863.","PeriodicalId":10331,"journal":{"name":"Circulation","volume":"35 1","pages":""},"PeriodicalIF":37.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
