Background and aims
The interplay between Th17-related immune activity and miRNA-driven regulation in abdominal aortic aneurysm (AAA) pathogenesis remains poorly understood. In this prospective study, we aimed to assess the potential role of miR-21-5p corresponding to the Th17 pathway disturbances in the development of AAA.
Methods
Biological samples were collected from patients with true infrarenal AAA, undergoing elective open abdominal aortic surgery, and patients with peripheral arterial disease (PAD) without concomitant aneurysms on the day of hospital admission for surgery. A fragment of aneurysmal abdominal aortic tissue was collected from patients intraoperatively. Total RNA was extracted from the samples, and the expression level of miR-21-5p and selected markers associated with Th17 pathway were assessed using quantitative real-time PCR (RT-qPCR) and Luminex assays, respectively. Moreover, we performed an in vitro model using human endothelial cells, transfected with a synthetic miR-21-5p mimic.
Results
We included 60 patients (30 in the study group and 30 in the control group, selected based on the propensity score matching method). Circulating miR-21-5p levels were significantly higher in AAA patients compared to controls. miR-21-5p downregulates genes involved in endothelial development, regulation of vascular permeability, or endothelial cell response to growth factors. We demonstrated that the Th17 circulating mediators were higher among AAA patients compared to controls, and were higher in the middle part of the aneurysmal aorta when compared to its upper pole.
Conclusion
Our study showed that, regarding AAA pathogenesis, endothelial dysfunction followed by inflammation could be mediated by an increased level of miR-21-5p.

Background
Due to overlapping symptoms and signs, it can be challenging to diagnose transthyretin amyloid cardiomyopathy (ATTR-CM) in the setting of concomitant aortic stenosis. Biomarkers may discriminate between heart failure with ATTR-CM and heart failure without ATTR-CM, but it is not known if these markers can differentiate between AS with and AS without concomitant ATTR-CM.
Methods
In 9 patients with ATTR-CM and AS, 161 patients with lone AS, and 23 healthy controls, we measured 8 plasma proteins previously identified by proteomic analysis as potential candidates for diagnosing ATTR-CM. We assessed differences between groups and association with indices of heart failure and AS severity.
Results
Plasma levels of dipeptidyl peptidase 4 (DPP4) were significantly higher in patients with AS and ATTR-CM than in patients with lone AS and in healthy controls. Lower levels of DPP4 were also associated with worse left ventricular function, higher New York Heart Association functional class, and low-flow, low-gradient aortic stenosis.
Conclusions
Our findings suggest that DPP4 may be a marker of ATTR-CM in patients with severe AS. In all AS patients, those with and without coexisting ATTR-CM, high DPP4 levels were asociated with better cardiac function.

Background
Patients with cardiac amyloidosis undergoing direct current electrical cardioversion (DCCV) are at risk of left atrial appendage thrombus (LAAT). We investigated LAAT formation rates, success rates, and long-term recurrence rates in transthyretin amyloid cardiomyopathy (ATTR-CM) patients.
Methods
ATTR-CM patients scheduled to undergo DCCV were included in the study. LAAT exclusion was performed utilizing transesophageal echocardiography or computed tomography.
Results
A total of 62 (1.35 per patient) DCCVs were recorded among 46 patients (77 ± 6.5 years, 89 % male) with ATTR-CM. In 39 DCCVs, LAAT exclusion was performed (62.9 %). In total, 10 DCCVs (16.1 %) were canceled due to (I) spontaneous conversion to sinus rhythm (n = 2, 5.1 %) or (II) definitive/suspected LAAT (n = 8, 20.5 %). Of these, five patients with LAAT had been receiving sufficient doses of oral anticoagulants for more than three weeks prior to DCCV. The immediate success rate was 92.3 %, and 3-month rhythm control was achieved in 27 (62.8 %) procedures. Notably, one stroke event was recorded two months following DCCV.
Conclusion
A high rate of left atrial appendage thrombus was observed in ATTR-CM, leading to DCCV cancellation in 20.5% of patients. Despite a high immediate success rate (92.3%), sustained sinus rhythm control was achieved in only 62.8% following DCCV. These findings advise using TEE or CT prior to DCCV to exclude LAAT in ATTR-CM patients, even in those with oral anticoagulation.

Catheter ablation has become a standard treatment for atrial fibrillation (AF). However, evidence regarding the efficacy and safety of pulsed field ablation (PFA) in patients with persistent AF (PeAF) remains limited. The PEACE trial aims to evaluate the efficacy and safety of PFA compared to cryoballoon ablation (CBA) in PeAF.
Methods
This prospective, multicenter, open-label, randomized controlled, non-inferiority trial (NCT07064616, UMIN000057896) will enroll 300 patients with PeAF, randomly assigned (1:1) to undergo either PFA using the PulseSelect™ or cryoballoon ablation (CBA) using the Arctic Front Advance™. The primary efficacy endpoint is atrial tachyarrhythmia recurrence within 12 months. The primary safety endpoint is procedure-related complications within 30 days. Secondary outcomes include early recurrence, changes in LA diameter, natriuretic peptide levels, and patient-reported symptoms.
Expected results
We hypothesize that PFA will be non-inferior to CBA in terms of efficacy and safety.
Conclusions
The PEACE trial will provide essential data regarding the efficacy and safety of PFA compared to CBA in patients with PeAF, potentially informing future clinical practice.
背景:导管消融已成为房颤(AF)的标准治疗方法。然而,关于脉冲场消融(PFA)治疗持续性房颤(PeAF)的有效性和安全性的证据仍然有限。PEACE试验旨在评估PFA与低温球囊消融(CBA)在PeAF中的疗效和安全性。方法:这项前瞻性、多中心、开放标签、随机对照、非效性试验(NCT07064616, UMIN000057896)将招募300名PeAF患者,随机分配(1:1)接受使用PulseSelect™的PFA或使用Arctic Front Advance™的冷冻球球消融(CBA)。主要疗效终点为12个月内房性心动过速复发。主要安全终点是30天内手术相关并发症。次要结局包括早期复发、LA直径改变、利钠肽水平和患者报告的症状。预期结果我们假设PFA在疗效和安全性方面不逊于CBA。PEACE试验将提供关于PFA与CBA在PeAF患者中的疗效和安全性的基本数据,可能为未来的临床实践提供信息。

Objectives
To identify predictors of intraoperative electrical cardioversion and develop a predictive model for patients undergoing radiofrequency ablation for atrial fibrillation (AF).
Methods
We retrospectively analyzed data from 1,348 patients with AF who underwent radiofrequency catheter ablation at Tongji Hospital between January 2018 and December 2023. Clinical, echocardiographic, and CT imaging data were collected. The Boruta algorithm and multivariable logistic regression were used to identify predictors and construct a nomogram. Model performance was assessed using the area under the ROC curve (AUC), calibration plots, and decision curve analysis (DCA). External validation was performed on 121 patients treated at Hubei No. 3 People’s Hospital of Jianghan University from June 2023 to February 2025.
Results
Patients were divided into training and validation sets (7:3 ratio). Five independent predictors were identified: AF type (OR = 13.63), valvular regurgitation (OR = 3.25), BMI (OR = 1.06), left atrial diameter (OR = 1.74), and systolic blood pressure (OR = 0.96). The nomogram showed excellent discriminative ability with AUCs of 0.881 (training), 0.879 (internal validation), and 0.866 (external validation). Calibration curves demonstrated good agreement between predicted and actual outcomes. DCA confirmed the model’s clinical utility.
Conclusions
The proposed nomogram accurately predicts the need for intraoperative electrical cardioversion during AF ablation and may aid in individualized procedural planning.

Cardamonin is a natural chalcone compound. It has been shown to have various pharmacological properties. Cardamonin can activate the Nrf2 signaling pathway. Abdominal aortic aneurysm (AAA) is a complex degenerative aortic disease. Ruptured AAAs continue to be among the leading causes of sudden death in elderly individuals. No medical therapy has proven clinical benefits for preventing AAA progression. Therefore, an adjunctive medical therapy is essential to address this unmet clinical need.
Methods
Human aortic smooth muscle cells (HASMCs) were used to determine the molecular mechanism of cardamonin. A murine model of angiotensin II (AngII)-induced AAA was used to assess the therapeutic effects of cardamonin on AAA growth in apolipoprotein E knockout (ApoE KO) mice in vivo. Immunoblotting, senescence assays, and reactive oxygen species (ROS) production assays were used to determine the protective effects of cardamonin in vivo and in vitro.
Results
Cardamonin induced Nrf2 translocation from the cytosol to the nuclear compartment in HASMCs. Cardamonin reduced AngII-induced ROS production and matrix metalloproteinases (MMPs) overexpression through activation of the Nrf2/heme oxygenase-1 (HO-1) antioxidant pathway in HASMCs. Silencing HO-1 attenuated the anti-ROS effects of cardamonin and abolished the protective effects of cardamonin in AngII-challenged HASMCs. Cardamonin (20 mg/kg/day) reduced AngII-induced AAA in vivo. Cardamonin also reduced the overexpression of MMPs and the production of ROS and attenuated elastin degradation in aortic tissues.
Conclusion
Cardamonin inhibits the progression of AngII-induced AAA through Nrf2/HO-1-mediated antioxidant and anti-inflammatory pathways. Cardamonin could have the potential to be an adjunctive therapy for small AAAs.
小豆蔻素是一种天然查尔酮化合物。它已被证明具有多种药理特性。小豆蔻素可以激活Nrf2信号通路。腹主动脉瘤(AAA)是一种复杂的退行性主动脉疾病。AAAs破裂仍然是老年人猝死的主要原因之一。没有任何药物治疗被证实对预防AAA进展有临床益处。因此,辅助医学治疗对于解决这一未满足的临床需求至关重要。方法采用人主动脉平滑肌细胞(HASMCs)研究小豆蔻素的分子机制。采用血管紧张素II (AngII)诱导的小鼠AAA模型,在体内评估小豆蔻素对载脂蛋白E敲除(ApoE KO)小鼠AAA生长的治疗作用。采用免疫印迹、衰老测定和活性氧(ROS)产生测定来确定小豆蔻素在体内和体外的保护作用。结果scardamonin诱导Nrf2从HASMCs细胞质转移到核室。小豆蔻素通过激活Nrf2/血红素氧化酶-1 (HO-1)抗氧化途径,降低血管内皮细胞诱导的ROS生成和基质金属蛋白酶(MMPs)的过度表达。沉默HO-1可减弱小豆蔻素的抗ros作用,并消除小豆蔻素在血管损伤的HASMCs中的保护作用。小豆蔻素(20 mg/kg/day)在体内降低血管损伤诱导的AAA。小豆蔻素还能降低主动脉组织中MMPs的过表达和ROS的产生,并减弱弹性蛋白的降解。结论小豆蔻素通过Nrf2/ ho -1介导的抗氧化和抗炎途径抑制血管内皮细胞诱导的AAA的进展。小豆蔻素有可能成为小型AAAs的辅助治疗方法。

Systematic and integrated comorbidity management in patients with atrial fibrillation (AF) requires patient involvement, starting with comorbidity awareness. This study evaluates comorbidity awareness in patients with AF before and after a first nurse-led AF clinic visit and after six months. We also measured the time needed for full comorbidity mapping using the EHRA-PATHS software.
Methods
This prospective two-centre study included patients diagnosed with AF attending the AF clinic for the first time. The software systematically assessed 23 comorbidities. Patients completed a comorbidity awareness questionnaire, focusing on nine AF-related comorbidities two weeks before their first visit, less than a week after, and six months later. Patients also had a telephone consultation with the AF nurse to discuss their comorbidities 1–3 months post-visit.
Results
The study included 76 patients (mean age 68.3 ± 10.3 y). Baseline awareness of comorbidity relevance for AF ranged between 11.1–100.0 %. Awareness about own alcohol consumption was the most ‘underestimated’ comorbidity before first contact (50.0 %), while smoking was most ‘overestimated’ (55.6 %; i.e. admitted in private but not during formal evaluation by nurses). The impact of an AF clinic visit on awareness of personal comorbidities was limited (p = 0.456), and also after an additional phone consultation, awareness was suboptimal after six months (p = 0.099). AF nurses needed 18.4 ± 8.7 min to complete the software.
Conclusions
Patients’ comorbidity awareness is moderate, and more educational efforts are needed to improve their awareness. A systematic and complete comorbidity evaluation at the AF clinic using EHRA-PATHS software can be done within a reasonable time frame.

Background
Aortic stenosis (AS) leads to pathological myocardial remodeling, particularly fibrosis, which contributes to adverse outcomes including heart failure, arrhythmias, and mortality. Evidence suggests sex-specific differences in fibrotic response, but individual studies are underpowered for definitive conclusions. This meta-analysis aimed to evaluate sex-related differences in myocardial fibrosis using cardiac magnetic resonance (CMR) parameters.
Methods
Three databases were searched for studies comparing male and female patients with AS reporting CMR-derived measures. The primary outcomes were late gadolinium enhancement (LGE%), infarct-related and non-infarct-related LGE, extracellular volume (ECV) and Septal E/e′. Effect sizes were expressed as risk ratios (RR) for binary outcomes and mean differences (MD) for continuous outcomes, each with 95% confidence intervals (CI), using random-effects models. Study quality was appraised with the Newcastle–Ottawa Scale, and certainty of evidence was graded using the GRADE framework.
Results
Seven studies (n = 2,105; 1,246 males) were included. No significant difference was observed in LGE% (MD 0.13; 95 %CI −0.93 to 1.18; p = 0.770), and risks of infarct-related LGE between sexes (RR 1.61; 95 %CI 0.90 to 2.89; p = 0.080). Males had higher risk of non-infarct LGE (RR 1.51; 95 %CI 1.34 to 1.70; p = 0.002). There were no significant differences in ECV (MD −0.45; 95 %CI −2.34 to 1.44; p = 0.506) and Septal E/e′ between sexes (MD −1.87; 95 %CI −4.05 to 0.32; p = 0.072).
Conclusion
This meta-analysis shows sex-related differences in myocardial fibrosis in AS, with men exhibiting more focal replacement fibrosis and women a tendency toward diffuse interstitial fibrosis. These patterns highlight the relevance of incorporating sex-specific factors into diagnosis and management.
主动脉狭窄(AS)导致病理性心肌重构,尤其是纤维化,导致心衰、心律失常和死亡等不良后果。证据表明,纤维化反应存在性别特异性差异,但个体研究不足以得出明确结论。本荟萃分析旨在利用心脏磁共振(CMR)参数评估心肌纤维化的性别相关差异。方法检索三个数据库,比较报告cmr衍生测量的男性和女性AS患者的研究。主要结局是晚期钆增强(LGE%)、梗死相关和非梗死相关LGE、细胞外体积(ECV)和间隔E/ E’。使用随机效应模型,用二元结果的风险比(RR)和连续结果的平均差异(MD)表示效应量,每个结果都有95%的置信区间(CI)。使用纽卡斯尔-渥太华量表评估研究质量,并使用GRADE框架对证据的确定性进行评分。结果纳入7项研究(n = 2105,男性1246)。LGE% (MD = 0.13; 95% CI = - 0.93 ~ 1.18; p = 0.770)和梗死相关LGE的风险在两性间无显著差异(RR = 1.61; 95% CI = 0.90 ~ 2.89; p = 0.080)。男性发生非梗死性LGE的风险较高(RR 1.51; 95% CI 1.34 ~ 1.70; p = 0.002)。两性间ECV (MD - 0.45, 95% CI - 2.34 ~ 1.44, p = 0.506)和鼻中隔E/ E′无显著差异(MD - 1.87, 95% CI - 4.05 ~ 0.32, p = 0.072)。这项荟萃分析显示了AS患者心肌纤维化的性别差异,男性表现出更多的局灶性替代纤维化,而女性倾向于弥漫性间质纤维化。这些模式突出了将性别特异性因素纳入诊断和管理的相关性。

Background
The quantitative videodensitometric aortography (QVDA) has reliably quantified post-TAVI aortic regurgitation (AR). However, this method has not yet been evaluated in randomized trials comparing various transcatheter heart valve (THV) systems. Here, we investigated the QVDA of AR following TAVI for severe aortic stenosis among Myval, Sapien, and Evolut THV series as part of the LANDMARK trial.
Methods
The final aortograms, either without or after balloon post-dilatation (BPD) were analyzed using the advanced CAAS-A-Valve 2.1.2 software. The regurgitant fraction (RF) was computed and categorized into none/trace AR (RF < 86 %), mild AR (6 % ≤ 8RF ≤ 817 %), and moderate/severe AR (RF > 17 %).
Results
Five hundred ninety-six final analyzable aortograms and 97 aortograms following BPD were included in the analysis. The BPD resulted in a significant reduction of RF in the Myval [12.0(6.0–18.5) vs 2.0(1.0, 5.5);p = 0.0002], Sapien[18.0(1.0–19.0) vs. 2.0(1.0–3.0); p = 0.04206] and Evolut [10.5 (6.0–15.0) vs 5.0 (1.0–8.0); p = 0.0009]. The rate of final RF > 17 % was lower in the Myval(2.0 %) compared to Evolut(8.00 %), but similar to the Sapien series (4.0 %)(PMyval-Sapien = 0.2333, PMyval-Evolut = 0.0057). In the as-treated population, the Myval series demonstrated a comparable RF to the Sapien series, but a significantly lower RF compared to the Evolut [Myval: 3.0 %(1.0–7.0), Sapien:3.0 %(1.0–7.0), Evolut:5.0 %(1.0–10.0)], PMyval-Sapien = 0.8997,PMyval-Evolut = 0.0010].
Conclusion
The QVDA highlights the superior performance of the Myval THV series compared to the Evolut THV series, with the lowest rate of moderate/severe RF among the three THV series, and could be used with echocardiography to help in detecting cases with none/trace AR.
