Background
The pathophysiology of heart failure with preserved ejection fraction (HFpEF) remains incompletely understood.
Objective
This study aimed to identify potential protein biomarkers for the accurate diagnosis and phenotyping of HFpEF and to construct a machine learning-based diagnostic model incorporating these biomarkers and key clinical features.
Methods
In a cross-sectional study of 249 cardiac patients, HFpEF-associated plasma proteins were identified using Olink PEA and validated by ELISA. A machine learning nomogram was developed and its diagnostic performance was evaluated.
Results
Analysis identified 92 plasma proteins,among which Serine protease 27(PRSS27), P-selectin glycoprotein ligand 1 (PSGL-1), Biregional Cell Adhesion Molecule-related (BOC), NF-κB essential modulator (NEMO), Glyoxalase 1(GLO1))) were specifically expressed in HFpEF group. Enrichment analysis indicated these differential proteins were primarily involved in inflammatory response, immune response, and the Phosphatidylinositol 3-kinase-AKT serine/threonine kinase (PI3K-AKT) signaling pathway. A diagnostic model integrating three proteins with clinical features (LDL-C, ALB) demonstrated excellent performance (AUC: 0.895), showing strong discriminatory power, good calibration, and potential clinical applicability.
Conclusion
This study identifies potential protein biomarkers for HFpEF diagnosis, provides new insights into its pathophysiology, and offers a practical diagnostic tool for clinical use.

Objective
Patients with alcohol use disorder (AUD) often receive inferior treatment for somatic comorbidities. We aimed to examine whether AUD is associated with disparities in the use of antiarrhythmic therapies (AAT) for rhythm control in atrial fibrillation (AF) patients, using a nationwide registry.
Methods
The Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) registry includes all 229,565 patients with incident AF diagnosed in Finland between 2007 and 2018, identified from comprehensive national healthcare registries. The primary outcome was initiation of rhythm control therapies, including antiarrhythmic drugs, cardioversion, and catheter ablation, in patients with and without AUD.
Results
The mean age was 72.7 years, 50 % were female and 4.7 % had AUD. Rhythm control was initiated less often in patients with AUD compared to those without (13.6 % vs. 21.8 %, p < 0.001). After adjustment for comorbidities and socioeconomic status, AUD remained associated with lower use of rhythm control therapies (HR 0.65; 95 % CI 0.62–0.69). This disparity was consistent across all modalities of rhythm control (antiarrhythmic drugs, cardioversion and catheter ablation). While no significant interaction was observed with sex or age, income modified the association (p < 0.001), with the lowest income tertile showing the greatest disparity (HR 0.37; 95 % CI 0.32–0.42).
Conclusions
AUD is independently associated with markedly lower use of rhythm control therapies in AF patients. These disparities are most pronounced among socioeconomically disadvantaged individuals, highlighting the need for targeted interventions to ensure equitable treatment access.

Background
DM1 is an autosomal dominant disorder caused by unstable CTG repeats that expand over lifetime and in successive generations, contributing to genetic anticipation. Cardiac conduction abnormalities (CCAs) are a major source of morbidity and premature death in DM1, yet the influence of age at diagnosis, generation, and CTG repeat length on the timing and progression of cardiac involvement remains poorly defined.
Method
This multicentric retrospective study included 549 adult DM1 patients from 16 hospitals in Spain. The primary composite endpoint comprised significant CCAs, device implantation, malignant ventricular arrhythmias and cardiac syncope. Patients were stratified by age‑at‑diagnosis (<40, 40–59, and ≥60 years); birth generation (1920–1965, 1966–1990, 1991–2015), and CTG repeat length (<100, 100–599, and ≥600).
Results
During follow‑up, 33.1 % of patients experienced the primary endpoint. This risk was 4.7‑fold higher in the youngest group versus the oldest group (HR 4.70; p < 0.001); 35‑fold higher in the 3rd generation versus the 1st and increased progressively with longer CTG expansions. Device implantation rates were likewise higher in younger patients, later generations, and those with larger repeat lengths.
Conclusion
The results demonstrate a striking anticipation pattern in the cardiac phenotype of DM1, with progressively earlier and more severe electrical disease paralleling CTG expansion across generations. Incorporating age at diagnosis, generational cohort, and genetic repeat burden into clinical assessment may enhance risk stratification and enable earlier, targeted rhythm surveillance and device therapy to prevent sudden cardiac death in DM1.
ddm1是一种常染色体显性遗传病,由不稳定的CTG重复序列在一生中和连续几代中扩展引起,有助于遗传预期。心传导异常(CCAs)是DM1发病和过早死亡的主要原因,但诊断年龄、世代和CTG重复长度对心脏受累时间和进展的影响仍不明确。方法本多中心回顾性研究纳入西班牙16家医院549例成年DM1患者。主要复合终点包括显著cca、器械植入、恶性室性心律失常和心源性晕厥。患者按诊断年龄分层(40岁、40 - 59岁和≥60岁);出生世代(1920-1965、1966-1990、1991-2015)和CTG重复长度(<;100、100 - 599和≥600)。结果在随访期间,33.1%的患者达到了主要终点。这一风险在最年轻组比最年长组高4.7倍(HR 4.70; p < 0.001);第三代比第一代高35倍,并随着CTG扩展时间的延长而逐渐增加。同样,在年轻患者、后代患者和重复长度较大的患者中,器械植入率也较高。结果表明,DM1的心脏表型具有显著的预测模式,随着CTG的代际扩展,电性疾病的发生时间越来越早,越来越严重。将诊断年龄、世代队列和遗传重复负担纳入临床评估可能会加强风险分层,并使早期、有针对性的节律监测和器械治疗成为可能,以预防DM1的心源性猝死。

Aims
This study reports sex differences in the clinical presentation, treatment management and outcomes of patients with acute coronary syndrome (ACS) in The Netherlands, using data from the FORCE-ACS registry.
Methods
A prospective analysis was conducted using data from 5023 patients admitted with ACS between 2015 and 2019, with complete three-year follow-up. Demographic data, clinical characteristics, in-hospital treatment and outcomes were compared by sex. Multivariable regression analyses explored associations between sex and clinical outcomes.
Results
Of the 5023 patients, 29 % were women. Women were generally older, with a significantly higher prevalence of hypertension (61.7 % vs 54.2 %), chronic kidney disease (25.7 % vs. 18.5 %) and myocardial infarction with non-obstructive coronary arteries (MINOCA) (13.5 % vs. 6.5 %). Women less frequently underwent revascularisation, even after excluding those with non-obstructive coronary artery disease, and received less medical treatment compared to their male counterparts. At 36 months, women had higher unadjusted mortality rate (13.7 % vs. 11.0 %, OR 1.28, 95 % CI: 1.07–1.54) and bleeding events (26.2 % vs. 22.3 %, OR 1.24, 95 % CI: 1.08–1.43). However, after adjustment for age and baseline characteristics, these differences were no longer statistically significant. Recurrent ACS and stroke remained similar in both groups, also after correction.
Conclusion
Differences between women and men were observed in clinical presentation, interventional treatment, pharmacotherapy and outcomes among ACS patients in The Netherlands. Despite receiving less guideline-recommended care, women had similar adjusted 36-month outcomes as men. These findings show that there is room for improvement in the management of ACS, with a focus on optimized treatment strategies for women.

The acute vasodilator challenge during right heart catheterization (RHC) provides a deeper understanding of the pulmonary circulation by assessing vasoreactivity. The current criteria for a positive acute vasoreactivity test (AVT) are simplified to steady-state metrics, based on cutoff points derived from expert opinion. A positive AVT identifies a specific, but very rare, PH phenotype that may respond long-term to calcium-channel blockers. Growing evidence supports updating the role and criteria of AVT in pulmonary arterial hypertension, broadening its use to other PH groups, and potentially offering new insights for predicting risk and/or treatment outcomes.
This study aims to revisit the uses, criteria, and goals of AVT in patients with PH beyond group 1 and to propose a new approach for phenotyping the pulmonary vascular response to the acute vasodilator challenge during diagnostic RHC. We propose a continuous multi-parameter criterion to evaluate the entire right ventricular afterload during AVT, such as the pulmonary vascular resistance-pulmonary arterial capacitance curve and alpha distensibility coefficient. AVT could assess the residual vasoreactive reserve of the pulmonary circulation as a provocative test for predicting risk outcomes and/or treatment responses.

Fatty acid-binding proteins (FABPs) are intracellular lipid-binding proteins that significantly contribute to the transport and metabolism of long-chain fatty acids and other hydrophobic ligands. In this review, we focus on the role of heart-type FABP (H-FABPs) as diagnostic and prognostic biomarkers in several cardiovascular diseases. Despite its advantages over troponins and other cardiac biomarkers, H-FABP remains underutilized in clinical practice. The aim of this review is to reassess the role of H-FABPs across various cardiovascular pathologies and promote their adoption into standard clinical practice. Elevated H-FABP levels have been associated with worse outcomes in CAD and serve as sensitive markers for myocardial injury during the early stages of MI and reperfusion. Furthermore, we discuss the potential of H-FABPs in risk stratification for stable CAD and their utility in predicting long-term outcomes post-MI. The prognostic value of H-FABP in cardiac events such as heart failure, pulmonary embolism, and arrhythmias, alongside its application in peripheral arterial disease and non-ischemic dilated cardiomyopathy, highlights its importance in cardiovascular medicine. Given the global burden of cardiovascular diseases, understanding and utilising H-FABPs could enhance patient management through better risk assessment and early diagnosis.

Background
The benefit-to-risk ratio of administration of intravenous (IV) and topical tranexamic acid (TXA) together in cardiac surgery has not yet been determined. This study aims to evaluate whether the combined approach (IV plus topical TXA) offers superior bleeding control compared to IV TXA alone, while maintaining an acceptable safety profile.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies comparing combined topical and intravenous TXA administration versus IV TXA alone in patients undergoing cardiac surgery. The primary outcome was cumulative blood loss. Secondary outcomes included all-cause mortality, transfusion-free status, and the number of transfused blood products. A random-effects model was used for all pooled analyses.
Results
We included a total of five studies (four RCTs, one observational; n = 880). Pooled analysis showed that the combined approach significantly, but modest, reduced total blood loss when compared to an IV-only TXA strategy (MD −39.84, 95 %CI −74.80 to −4.88; p = 0.03; I2 = 39 %). However, this benefit did not translate into a significant reduction in transfusion requirements (OR 1.00, 95 %CI 0.72 to 1.37; p = 0.98; I2 = 0 %), volume of blood products used (MD −0.01, 95 %CI −0.04 to 0.02; p = 0.51; I2 = 0 %), or all-cause mortality (OR 0.85, 95 %CI 0.24 to 3.08; p = 0.81; I2 = 0 %).
Conclusion
Combined topical and IV TXA application is associated with reduced total blood loss after cardiac surgery compared to an IV-only approach. However, no significant differences were observed in transfusion rates, blood product utilization, or mortality.

Introduction
Oxygen therapy does not benefit normoxemic patients with suspected myocardial infarction and may instead enhance the inflammatory response triggered by the tissue necrosis caused by the myocardial infarction. In the present study, we tested the hypothesis that oxygen therapy aggravates systemic inflammation in normoxemic healthy individuals in a human model of experimental inflammation.
Methods
Proteomic and gene expression data from healthy subjects vaccinated against Salmonella Typhii and exposed to oxygen therapy or ambient air were investigated. A multi-omics approach with factor analysis to identify common sources of variation in the systemic inflammatory response associated with oxygen exposure was used.
Results
Oxygen therapy showed a statistically nominal tendency toward aggravation determined by ELISA (IL-6) and proximity extension assay (IL-8). The factor analysis revealed a pro-inflammatory feature that included increases in (CXCL 6, 10 and 11) with decreased small nucleolar RNA.
Conclusion
The results indicate that oxygen therapy enhances experimental systemic inflammation. The mechanism is not clear but future studies should address small nucleolar RNA.

Background
Pulsed field ablation (PFA) is an emerging non-thermal modality for pulmonary vein isolation (PVI) in atrial fibrillation (AF), offering enhanced tissue selectivity and reduced collateral damage compared to cryoballoon ablation (CBA).
Objective
This meta-analysis compares the mid- to long-term efficacy, safety, and procedural characteristics of PFA versus CBA in AF treatment.
Methods
A systematic search of PubMed, EMBASE, and the Cochrane Library through July 2025 identified nine comparative studies involving 2,718 patients (1,381 PFA; 1,337 CBA). Pooled risk ratios (RRs) and mean differences (MDs) were calculated using random-effects models, with subgroup analyses for paroxysmal and persistent AF.
Results
PFA showed a trend toward lower recurrence rates (RR = 0.86, 95 % CI: 0.70–1.04), particularly in paroxysmal AF (RR = 0.83, 95 % CI: 0.68–1.01), while outcomes in persistent AF were comparable (RR = 0.98, 95 % CI: 0.69–1.38). Procedure time was significantly shorter with PFA (MD = –9.59 min, 95 % CI: –17.80 to –1.37), whereas fluoroscopy duration showed no significant difference. Safety analysis revealed a non-significant trend favoring PFA (RR = 0.75, 95 % CI: 0.49–1.14), with fewer cases of phrenic nerve injury and cardiac tamponade.
Conclusion
PFA and CBA demonstrate comparable efficacy and safety in AF ablation. PFA may offer procedural advantages and improved outcomes in paroxysmal AF, supporting its expanding role in clinical practice. Further randomized trials are warranted to validate these findings and guide optimal treatment strategies.
