However, integrated assessment of biventricular (LV/RV) volumetric reserve under physiological stress remains underexplored. We aimed to investigate whether exercise cardiac magnetic resonance (Ex-CMR) can reveal distinct volumetric reserve profiles across the HFpEF spectrum.METHODSIn this retrospective analysis of a prospective observational, multicentre study, supine ergometer Ex-CMR was performed in HFpEF patients across early to advanced stages (stage B, exercise-induced, stage C), along with healthy controls and a non-cardiac dyspnoea (NCD) group. Percentage changes in LV/RV end-diastolic (ΔEDV%) and end-systolic volumes (ΔESV%) from rest to stress defined EDV reserve and ESV reserve, respectively. Ventricular efficiency index (EI) was defined as ΔEDV%-ΔESV%; biventricular EI as LVEI + RVEI. Group comparisons were performed using ANOVA and post hoc testing. Multivariable general linear model analyses adjusted for age, sex, BMI, and exercise response. A composite phenotyping assessment incorporating all four key reserve parameters was explored.RESULTSAmong 140 participants (40 healthy, 27 NCD, and 73 HFpEF), all HFpEF subgroups showed impaired LVEDV reserve and reduced LVEI (P < .0001). LVESV reserve was impaired only in stage C (P < .0001). Exercise-induced RV dysfunction was a hallmark of HFpEF with pulmonary hypertension (P < .0001). Biventricular EI declined progressively with advancing HFpEF stage (P < .0001) and was significantly lower in NYHA > II (P = .0006). Six distinct reserve phenotypes emerged.CONCLUSIONEx-CMR-based assessment of LV/RV volumetric reserve reveals progressive biventricular dysfunction across HFpEF stages and supports biventricular volumetric reserve-based phenotyping for characterizing HFpEF pathophysiology.KEY QUESTIONCan the integration of left and right ventricular end-diastolic and end-systolic volume reserve under physiological stress reveal distinct profiles across the HFpEF spectrum and enhance our understanding of its haemodynamic heterogeneity?KEY FINDINGSNon-invasive assessment of biventricular volumetric reserve, along with their intra- and interventricular interactions using exercise CMR, revealed a significant, stepwise deterioration across HFpEF subgroups, worsening with NYHA class > II. Exercise CMR enabled composite volumetric reserve-based phenotyping and identified six distinct reserve phenotypes.TAKE HOME MESSAGEBiventricular volumetric reserve assessment is feasible through exercise CMR and may support future precision therapy strategies.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"3 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695163","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}

We aimed to determine incidence and clinical risk factors for HF events among patients with SCAF.METHODSWe included 3986 patients from the ARTESiA (Apixaban for the Reduction of Thromboembolism in Patients with Device-Detected Subclinical Atrial Fibrillation) trial. ARTESiA investigated the effect of apixaban versus aspirin for stroke prevention in patients with episodes of SCAF ≤24 hours. In this secondary analysis, we explored the number and duration of SCAF episodes at baseline as risk markers for HF hospitalization or HF-related death. SCAF progression was analysed as a time-dependent covariate and defined as the development of SCAF >24 hours or clinical atrial fibrillation.RESULTSOver a mean follow-up of 4.1 ± 1.7 years, SCAF progression was observed in 1244 patients (31%). Heart failure hospitalization or HF-related death occurred in 515 (13%) patients at a rate of 3.3 [95% confidence interval (CI) 3.1-3.6] per 100 person-years. A total of 172 HF-related events occurred after SCAF progression (7.2 events, 95% CI 6.2-8.3, per 100 PY). SCAF progression was an independent risk factor for HF hospitalization or HF-related death (hazard ratio 2.72, 95% CI 2.24-3.31).CONCLUSIONHeart failure hospitalization and HF-related death are common in patients with SCAF. Progression to longer SCAF episodes or clinical AF were associated with HF events, but episodes <24 h were not. These findings underscore the need for close surveillance of SCAF patients to detect complications and potentially improve outcomes.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"84 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147666580","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}

We aimed to investigate underlying metabolic remodelling in an ovine model.METHODS AND RESULTSEleven sheep with dual-chamber-pacemakers for LBBB-like activation (DHF) were studied at baseline and after eight weeks. Six untreated sheep served as controls (CTRL). Regional workload was evaluated using invasive hemodynamics and echocardiography. 18F-fluorodeoxyglucose-tracer positron-emission-tomography/computed tomography visualized regional glucose-uptake. Magnetic resonance imaging assessed fibrosis (late gadolinium enhancement, LGE). Septal and lateral wall tissue was analysed with histology, confocal microscopy, ultra-high-performance liquid chromatography-high resolution mass-spectrometry (UHPLC-HRMS). Dyssynchrony induced low septal and high lateral asymmetry in workload and glucose-uptake. After eight weeks, DHF animals exhibited LV dilation and LVEF decline (31.1±5.1% vs. 59.4±3.5% at baseline, p<0.05). Septal thinning and lateral hypertrophy rebalanced workload and glucose-uptake. No fibrosis was seen on LGE or histology. DHF-animals showed enrichment of mitochondria at the intercalated discs (EMID-sign) - highest in the lateral wall (DHF septal 7.0±4.8% vs. lateral 48.4±12.3%, p<0.05). Mitochondrial redox balance in DHF shifted towards a more oxidised state without evidence of oxidative stress. Metabolomics revealed no differences between septal and lateral walls but severe energy depletion of tricarboxylic acid cycle substrates and phosphocreatine in DHF (fold change DHF/CTRL 0.01, p<0.01).CONCLUSIONExperimental DHF is characterised by non-fibrotic, dilated LV without signs of oxidative stress. Workload increase in the lateral wall leads to hypertrophy and EMID, homogenizing metabolic profiles between wall segments.
