We aimed to assess sex‐specific outcomes in the Intravenous Iron in Patients with Systolic Heart Failure and Iron Deficiency to Improve Morbidity &amp; Mortality (FAIR‐HF2‐DZHK05) trial.Methods and resultsFAIR‐HF2 included 1105 heart failure patients with a left ventricular ejection fraction ≤45% and iron deficiency. A total of 368 women (mean age 68.7 ± 13.0 years) and 737 men (mean age 70.5 ± 11.0 years) were randomized to intravenous ferric carboxymaltose or placebo. The three primary endpoints were (i) time to cardiovascular death or first heart failure hospitalization, (ii) total heart failure hospitalizations, and (iii) time‐to‐first event of cardiovascular death or heart failure hospitalization only in patients with transferrin saturation &lt;20% at baseline. The hazard ratio (HR) for the first primary outcome was 1.07 (95% confidence interval [CI] 0.63–1.82, <jats:italic>p</jats:italic> = 0.80) in women and 0.74 (95% CI 0.57–0.95, <jats:italic>p</jats:italic> = 0.016) in men, while the rate ratios (RRs) for the second primary outcome were 1.06 (95% CI 0.55–2.05, <jats:italic>p</jats:italic> = 0.86) and 0.79 (95% CI 0.58–1.08, <jats:italic>p</jats:italic> = 0.136), respectively, and the HRs for the third primary outcome event were 1.21 (95% CI 0.62–2.36, <jats:italic>p</jats:italic> = 0.58) and 0.73 (95% CI 0.55–0.97, <jats:italic>p</jats:italic> = 0.028), respectively. Regarding safety outcomes, the HR for all‐cause mortality was 1.46 (95% CI 0.78–2.76, <jats:italic>p</jats:italic> = 0.24) in women, suggesting increased mortality risk under iron supplementation, in contrast to 0.86 (95% CI 0.64–1.16, <jats:italic>p</jats:italic> = 0.33) in men (<jats:italic>p</jats:italic> for interaction = 0.13).ConclusionsThis analysis indicates relevant differential efficacy of intravenous iron in heart failure across both sexes. While men receiving ferric carboxymaltose experienced a clinically relevant reduction in cardiovascular death and heart failure hospitalizations, women did not derive similar benefits. The results are clinically relevant and prompt validation in other large outcome trials of intravenous iron supplementation in heart failure.Clinical Trial Registration: ClinicalTrials.gov NCT03036462.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"718 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747226","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 use of machine learning (ML) methods may help to identify high‐risk patients and to initiate therapy. In this study, we develop ML models for risk stratification of parvovirus B19 (B19V) positive patients with HF based on key features from multiparametric EMB analyses.Methods and resultsWe retrospectively enrolled 263 B19V‐positive patients with HF (mean age 51 ± 15 years, 62% male) and followed them over a median period of 22 months (interquartile range 4–35 months). All‐cause mortality, left ventricular (LV) deterioration and persistent LV systolic dysfunction were used as clinical combined endpoint. EMB were analysed for a variety of inflammatory and infectious markers, and patient prognosis was assessed using ML methods (logistic regression, random forest, support vector machines and gradient boosting). Detection of intramyocardial inflammation and B19V viral activity was associated with poor clinical outcome (hazard ratio 3.50, 95% confidence interval 1.96–6.23, <jats:italic>p</jats:italic> &lt; 0.001). Linear combination of demographic and clinical data with multiparametric EMB markers increased the prognostic performance (area under the curve [AUC] = 0.724) compared to using single features (AUC = 0.667). The use of gradient boosting ML methods significantly improved the accuracy of risk prediction (AUC = 0.926).ConclusionsIntramyocardial inflammation and B19V viral activity were detected more frequently in patients with poor clinical outcome, suggesting that they are risk factors for death and LV dysfunction. Using multiparametric EMB data, we present an ML‐based prognostic tool that can determine the clinical outcome of patients with a high degree of accuracy. This could be helpful in assessing the progression of the disease and making appropriate treatment decisions.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"30 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715710","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}

Geranylgeranylacetone (GGA) has been shown to improve myocardial compliance and endothelial function in preclinical models. Given the mechanistic profile of GGA and established safety as an over-the-counter drug in Asia, we performed a phase 2 clinical trial in patients with HFpEF.METHODS AND RESULTSGLADIATOR-HFpEF (NCT05672134, EudraCT2022-000655-36-NL) is a phase 2, double-blind, randomized, placebo-controlled, crossover trial. Patients were randomized 1:1 to GGA or placebo and treated for 3 months with a washout-period of 6 weeks. The dual primary endpoints were diastolic function (E/e') and reactive hyperaemia index (RHI). Secondary endpoints were renal haemodynamic measurements; measured glomerular filtration rate and effective renal plasma flow, New York Heart Association class and 6-min walking test distance, cardiac biomarkers (N-terminal pro-B-type natriuretic peptide [NT-proBNP], high-sensitivity C-reactive protein), quality of life and laser speckle contrast analysis. Between March 2023 and December 2023, 43 patients were randomized and 39 were included in the per-protocol analysis. The cohort consisted of 28 women (72%), mean left ventricular ejection fraction was 59% and median NT-proBNP was 238 ng/L. There were no significant differences in the primary outcomes; E/e' (-0.24 [-0.90-0.41], p = 0.46) and RHI (-0.02 [-0.36-0.33], p = 0.92).
