Modifications in metal homeostasis are linked to epigenetic mechanisms. However, the epigenetic mechanisms through which metal affects cardiac fibrosis (CF) remain poorly understood. Methods The metal content of mouse heart samples was measured using inductively coupled plasma mass spectrometry. Cardiac fibroblast-specific MeCP2-deficient mice and control mice were treated with isoprenaline/angiotensin II to induce CF. AAV9 carrying POSTN promoter-driven small hairpin RNA targeting MeCP2, YTHDF1, or SLC31A1 and the copper-chelating agent tetrathiomolybdate were administered to investigate their vital roles in CF. Histological and biochemical analyses were performed to determine how YTHDF1/MeCP2 regulated SLC31A1 expression in CF. The reconstitution of SLC31A1 in YTHDF1/MeCP2-deficient cardiac fibroblasts and mouse hearts was performed to study its effect on mitochondrial copper depletion and fibrosis. Human heart tissues from atrial fibrillation patients were used to validate the findings. Results Lower copper concentrations are accompanied by SLC31A1 down-regulation and mitochondrial copper depletion in CF. Fibroblast-specific SLC31A1 deficiency enhances mitochondrial copper depletion, augments glycolysis, promotes fibroblast proliferation and triggers CF. SLC31A1 inhibition due to increased MeCP2-recognized methylating CpG islands of SLC31A1 in the promoter region restrains its transcription. Conversely, MeCP2 knockdown rescued SLC31A1 expression, resulting in contradictory effects. MeCP2 up-regulation is associated with elevated m6A mRNA levels. Mechanistically, YTHDF1 recognizes target MeCP2 mRNA and induces its translation. In human heart tissues from atrial fibrillation patients, reduced copper concentrations and SLC31A1 expression, along with elevated levels of YTHDF1 and MeCP2, were observed. These changes were associated with mitochondrial copper depletion, enhanced glycolysis, and CF. Conclusions A novel epigenetic mechanism was demonstrated through which copper deficiency increases mitochondrial copper depletion and impairs CF. Findings provide new insights for the development of preventive measures for CF.","PeriodicalId":11976,"journal":{"name":"European Heart Journal","volume":"18 1","pages":""},"PeriodicalIF":39.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143570431","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}

The aim of this study was to explore differences in outcomes of participants treated with medical therapy alone in STICHES vs. REVIVED-BCIS2 and to assess the incremental benefit of CABG or PCI. Methods Pooled analysis of adjusted individual participant data from two multicentre randomized trials. All patients had left ventricular ejection fraction ≤35% and coronary artery disease and received medical therapy. Participants were randomized 1:1 to CABG (STICHES) or PCI (REVIVED-BCIS2). The primary outcome was the composite of all-cause death and hospitalization for heart failure over all available follow-up.

The median follow-up was 118 months in STICHES and 41 months in REVIVED-BCIS2. Those receiving medical therapy alone in REVIVED-BCIS2 had fewer primary outcome events than those receiving medical therapy alone in STICHES (adjusted hazard ratio 0.60, 95% confidence interval 0.48–0.74, P < .001).

This study was conducted to determine the feasibility of a high intensity exercise programme and explore safety and efficacy outcomes in patients with HCM. Methods Participants were randomized to a 12-week supervised exercise programme (n = 40) in addition to usual care, or usual care alone (n = 40). All participants underwent assessment at baseline and 12 weeks. The exercise group was re-evaluated 6 months post-programme. Feasibility was assessed by (i) recruitment, adherence, and retention rates; (ii) staffing ratios; (iii) logistics; and (iv) acceptability of the intervention. The primary exploratory safety outcome was a composite of arrhythmia-related events. Exploratory secondary outcomes included changes in (i) cardiorespiratory fitness; (ii) cardiovascular risk factors; and (iii) quality of life, anxiety, and depression scores. Results Overall, 67 (84%) participants completed the study (n = 34 and n = 33 in the exercise and usual care groups, respectively). Reasons for non-adherence included travel, work, and family commitments. Resource provision complied with national cardiac rehabilitation standards. There was no difference between groups for the exploratory safety outcome (P = .99). At 12 weeks, the exercise group had a greater increase in peak oxygen consumption (VO2) [+4.1 mL/kg/min, 95% confidence interval (CI) 1.1, 7.1] and VO2 at anaerobic threshold (+2.3 mL/kg/min, 95% CI 0.4, 4.1), lower systolic blood pressure (−7.3 mmHg, 95% CI −11.7, −2.8) and body mass index (−0.8 kg/m2, 95% CI −1.1, −0.4), and greater improvement in hospital anxiety (−3, 95% CI −4.3, −1.7) and depression (−1.7, 95% CI −2.9, −0.5) scores, compared to the usual care group. Most exercise gains dissipated at 6 months. Conclusions A high intensity exercise programme is feasible in patients with HCM, with apparent cardiovascular and psychological benefits, and no increase in arrhythmias. A large-scale study is required to substantiate findings and assess long-term safety of high intensity exercise in HCM.","PeriodicalId":11976,"journal":{"name":"European Heart Journal","volume":"7 1","pages":""},"PeriodicalIF":39.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546539","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}

Specific data on natural course and outcome under tafamidis treatment in octogenarians are therefore scarce. The impact of tafamidis treatment on mortality in real-world wild-type transthyretin cardiomyopathy octogenarians was studied. Methods An international, multicentre cohort study of 710 consecutive wild-type transthyretin cardiomyopathy patients with mean follow-up of 2.2 ± 1.8 years for all-cause mortality endpoint was performed. Results The cohort consisted of 58.5% (415/710) octogenarians (85 ± 4 years, 74.2% male). Before tafamidis availability, natural course in octogenarians (148/257) vs. non-octogenarians (109/257) was poor, with 16% 1-year and 71% 5-year mortality vs. 8% and 47%, respectively (P &lt; .001).

Tafamidis discontinuation was similar (octogenarians 10.3% and non-octogenarians 7.4%; P = .260). Overall tafamidis treated vs. untreated octogenarians had better unadjusted survival (P &lt; .001), with 5% 1-year and 24% 3-year mortality.
