The knowledge of pericardial diseases has now improved, including prospective and retrospective cohort studies focusing on the pathogenesis, diagnosis, treatment, and outcomes. The complex interplay between genetic predisposition (especially for autoinflammatory conditions), inflammation, and autoimmunity is now known to trigger recurrences of pericarditis. Moreover, diagnostic capabilities have improved with the implementation of multimodality imaging, particularly cardiac magnetic resonance (CMR), to detect and monitor pericardial inflammation, to allow diagnosis in more complicated cases, and tailor the duration of therapy based on objective parameters. A new class of drugs, the anti-IL-1 agents, have been introduced for patients with an inflammatory phenotype of presentation, and not responding to conventional anti-inflammatory therapies, including NSAID, colchicine, and corticosteroids. At present, the clinical management of pericardial diseases is definitely on the road of evidence-based medicine with new ongoing European guidelines focusing on the spectrum of inflammatory myocardial and pericardial syndromes.

Aims: Tricuspid regurgitation affects 7% of the population, with moderate-to-severe tricuspid regurgitation contributing to up to 12% of heart failure-related hospitalizations. Traditional treatments have several limitations, prompting the exploration of innovative interventions. Our study aims to investigate the efficacy and clinical outcomes following transcatheter edge-to-edge repair (TEER) in patients with severe, symptomatic tricuspid regurgitation through a 1-year follow-up.

Methods: The TR-Interventional study (TRIS) is a prospective, single-arm study conducted at the Fondazione Policlinico Universitario Campus Bio-Medico. From March 2021 to December 2023, we enrolled 44 symptomatic patients with at least severe tricuspid regurgitation referred for tricuspid TEER with the TriClip System.

Results: The study cohort had a mean age of 78.3 ± 7 years with a median TRISCORE 5.4% (interquartile range 3.5-9.0). Significant reduction in tricuspid regurgitation grade occurred immediately after the procedure with durable results at 30 days and 1-year follow-up (P < 0.001). The primary efficacy endpoint, which assesses the successful implantation and performance of the device at 30 days, was attained in 82.9% of patients. The secondary efficacy endpoint, evaluating the stability of tricuspid regurgitation reduction at 12 months, was achieved in 82.3% of patients. The NYHA Functional Class and KCCQ scores significantly improved from baseline to 1 year (P < 0.05; P < 0.0001). Echocardiographic assessments reveal sustained positive right ventricle remodeling throughout the 1-year follow-up period.

Conclusion: Evidence from the TRIS study confirms that tricuspid TEER is a valuable and effective therapeutic option in contemporary practice. The lasting reduction in tricuspid regurgitation at 1 year is associated with sustained clinical benefits and reverse structural remodeling of the right ventricle.

Neutrophils activation plays a pivotal role in the pathogenesis of atherosclerotic plaque formation, progression and rupture. An association between the leukocyte count and the risk of developing myocardial infarction has been well known for many years; however, only recently did Mendelian randomization studies show that a high neutrophil count is a causal risk factor for atherosclerotic cardiovascular disease. On the other hand, experimental studies show that depletion of circulating neutrophils impairs plaque development. Clopidogrel, an antiplatelet agent, is widely used in combination with aspirin to reduce the incidence of ischemic events in patients treated with coronary stenting. Chronic treatment with this drug reduces inflammatory markers and neutrophil numbers, rarely causing severe leukopenia. The purpose of this review is to present recent evidence showing the link between neutrophil number and the development of cardiovascular diseases and to discuss how the clopidogrel-induced reduction in the neutrophil count may be a beneficial off-target effect of this drug.

Background: Risk stratification in drug-induced type-1 Brugada syndrome (BrS) patients is challenging. The role of electrophysiological study (EPS) is debated as the majority of drug-induced type-1 BrS patients would not be studied according to the latest recommendations.

Methods: A complete systematic literature search was performed to gauge the EPS role in this population. Three subgroups were defined: positive-EPS group, negative-EPS group, no-EPS group.

Results: Among 1318 drug-induced type-1 BrS patients, no significant difference in the incidence rate of arrhythmic events was observed between groups (I2 = 45%, P for subgroup difference = 0.10) during a mean follow-up of 5.1 years, also considering symptomatic status.

Conclusion: In long-term follow-up of drug-induced type-1 BrS patients, EPS does not seem to aid prognostic stratification.

Background: Cardiovascular risk assessment is a critical component of healthcare, guiding preventive and therapeutic strategies. In this study, we developed and evaluated an image-based electrocardiogram (ECG) analyzing an artificial intelligence (AI) model that estimates biological age and mortality risk.

Methods: Using a dataset of 978 319 ECGs from 250 145 patients at Seoul National University Bundang Hospital, we developed a deep-learning model utilizing printed 12-lead ECG images to estimate patients' age (ECG-Age) and 1- and 5-year mortality risks. The model was validated externally using the CODE-15% dataset from Brazil.

Results: The ECG-Age showed a high correlation with chronological age in both the internal and external validation datasets (Pearson's R = 0.888 and 0.852, respectively). In the internal validation, the direct mortality risk prediction models showed area under the curves (AUCs) of 0.843 and 0.867 for 5- and 1-year all-cause mortality, respectively. For 5- and 1-year cardiovascular mortality, the AUCs were 0.920 and 0.916, respectively. In the CODE-15%, the mortality risk predictions showed AUCs of 0.818 and 0.836 for the prediction of 5- and 1-year all-cause mortality, respectively. Compared to the neutral Delta-Age (ECG-Age - chronological age) group, hazard ratios for deaths were 1.88 [95% confidence interval (CI): 1.14-3.92], 2.12 (95% CI: 1.15-3.92), 4.46 (95% CI: 2.22-8.96) and 7.68 (95% CI: 3.32-17.76) for positive Delta-Age groups (5-10, 10-15, 15-20, >20), respectively.

Conclusion: An image-based AI-ECG model is a feasible tool for estimating biological age and assessing all-cause and cardiovascular mortality risks, providing a practical approach for utilizing standardized ECG images in predicting long-term health outcomes.

Aims: Secondary mitral regurgitation (MR) negatively affects prognosis in acutely decompensated heart failure (ADHF), but can be rapidly sensitive to changes in volume status and medical interventions. We sought to assess the evolution of secondary MR in patients hospitalized for ADHF and its prognostic implications.

Methods: We retrospectively enrolled 782 patients admitted for ADHF with at least two in-hospital echocardiographic evaluations of MR. We classified MR severity as none-mild or moderate-severe. Based on MR evolution, patients were divided into 'persistent moderate-severe MR', 'improved MR' (from moderate-severe to none-mild) and 'persistent none-mild MR'.

Results: Four hundred and forty patients (56%) had moderate-severe MR at first evaluation, of whom 144 (33% of patients with baseline moderate-severe MR) had 'improved MR', while 296 (67%) had 'persistent moderate-severe MR'. Patients with improved MR had better clinical, laboratory and echocardiographic parameters of decongestion at discharge compared with those with persistent moderate-severe MR and showed a higher up-titration of recommended therapies. Left ventricular volume, ejection fraction and serum urea were the predictors of improved MR at multivariable analysis. After adjustment, no differences in 5-years survival (primary outcome) were observed according to baseline MR severity. When patients were stratified according to the in-hospital changes in MR severity, improved MR was associated with lower risk of 5-years mortality, compared with both persistent none-mild MR [hazard ratio (HR) = 0.505, P = 0.032] and persistent moderate-severe MR (HR = 0.556, P = 0.040).

Conclusions: The severity of MR frequently improved during hospitalization for ADHF; the extent and the changes in MR severity during the in-hospital stay identified distinct patient phenotypes, and seemed to portend different long-term outcomes, with higher 5-years survival associated with improvement in MR.

Aims: Presence of family cases and multiple recurrences of pericarditis suggest the existence of a possible genetic background in at least 10% of cases. The aim of the present study is to describe the genetic landscape of a cohort of patients with multiple recurrences (at least two recurrences).

Methods: Retrospective cohort study of consecutive adult patients referred for at least two episodes of recurrences in a tertiary referral centre. Genetic testing was performed by whole exome sequencing (WES).

Results: Our cohort included 108 consecutive patients with recurrent pericarditis [median age 32 years, interquartile range (IQR) 18.5; 67.6% females, all Caucasian, idiopathic aetiology in 71.1%] with a median number of recurrences of 5 (IQR 2). Overall, 16 patients (14.8%) had variants in genes related to the inflammatory response. Eleven variants were located in genes already associated with recurrent pericarditis (NLRP3, TNFRSF1A and MEFV) and five in inflammation/immunodeficiency-related genes (IFIH1, NFKBIA, JAK1, NOD2 and ALPK1). Furthermore, we identified 10 patients with variants located in genes associated with conduction system-related diseases, and 22 variants in 21 patients with genes associated with heart structural-related diseases.

Conclusion: In this first observational study using WES to assess genetic variants in patients with multiple recurrences of pericarditis, about 15% of patients bore at least one variant that may be related to the disease. These findings highlight the importance of addressing the role of genetic predisposition in recurrent pericarditis. Moreover, 28.7% of patients carry variants in different cardiac genes, worthy of a deeper investigation.

Aims: The impact of sex-related factors on current clinical management and outcomes of chronic coronary syndromes (CCS) are unclear.

Methods: All patients belonging to the prospective, nationwide START registry were included. Their baseline characteristics, diagnostic workup, revascularization strategy, pharmacological treatment and 1-year clinical outcomes were compared with respect to sex overall and in age tertiles.

Results: A total of 5070 consecutive patients were included. Most patients were males (80.1%). As expected, the prevalence of females increased with age. Distribution of risk factors and history of cardiovascular disease were different depending on sex, as well as diagnostic workup, with lower use of exercise stress testing in women (25.1% vs. 36.7%, P < 0.0001). The use of coronary angiography was similar in the two groups. Women had lower rates of multivessel coronary artery disease (CAD) (33.0% vs. 40.6% P < 0.0001) and higher rates of nonobstructive CAD (18.3% vs. 11.3%, P < 0.0001). Rates of myocardial revascularization were similar, but women were more likely to receive percutaneous coronary intervention than men (84.3% vs. 77.8%, P < 0.0001) and less likely to receive surgical/hybrid revascularization (10.0% vs. 15.1%, P < 0.0001). At 12-month follow-up, no differences were observed for the combined endpoint of all-cause mortality, re-hospitalization for myocardial infarction, heart failure, stroke or myocardial revascularization between males and females; however, a significantly worse perceived quality of life was observed in women.

Conclusions: In a large nationwide cohort of patients with CCS, clinical outcomes were not different depending on sex. However, several differences in the diagnostic work-up, treatment strategies and quality of life were found between sexes.
