Article Synopsis
  • Nanomedicine using cell membrane coatings has gained interest due to improved targeting and reduced side effects, particularly focusing on treating myocarditis through IRF1-mediated macrophage pyroptosis.
  • Researchers created a zeolitic imidazolate framework-8 (ZIF-8) nano-delivery system encapsulating siRNA aimed at IRF1, which was coated with a hybrid membrane from T lymphocytes and macrophages for efficient targeting.
  • Findings indicated that the developed nanoparticles effectively delivered siRNA, reduced IRF1 expression, and decreased pyroptosis in macrophages, leading to a significant reduction in myocarditis progression in mice with minimal adverse effects.

Postmenopausal women with negative personality characteristics are at an increased risk of psychological disorders, yet little is known about the mechanism underlying the relationship between type D personality and psychological distress in postmenopausal women with coronary disease. This study assessed the mediating roles of perceived social support and self-perceived burden in the relationship between type D and psychological distress based on the equity theory and stress-buffering model. Demographic characteristics, type D, psychological distress, perceived social support, and self-perceived burden were completed by 335 participants with self-reported questionnaires using a cross-sectional design in Southeast China.

Background: Catheter ablation of premature ventricular contractions (PVCs) that trigger polymorphic ventricular tachycardia (PVT) or ventricular fibrillation has been reported as a novel therapy to reduce the syncope events in patients with catecholaminergic PVT, whereas the long-term ablation outcome and its value in improving exercise-induced ventricular arrhythmias remain unclear.

Methods And Results: Fourteen consecutive selected patients with catecholaminergic PVT (mean±SD age, 16±6 years; 43% male patients) treated with maximum β-blockers with no possibility of adding flecainide were prospectively enrolled for catheter ablation. The primary end point was syncope recurrence, and the secondary end point was the reduction of the ventricular arrhythmia score during exercise testing.

Article Synopsis
  • - The study investigates whether catheter ablation as a first-line treatment for ventricular tachycardia (VT) during implantable cardioverter defibrillator (ICD) implantation is more effective than standard medical therapy plus ICD in patients with cardiomyopathy.
  • - The trial involved 180 patients and found that those in the ablation group showed lower recurrence rates of VT and required fewer ICD shocks compared to the control group over an average follow-up period of 31 months.
  • - Results suggest that early ablation may offer significant benefits in reducing VT recurrence and hospitalizations for patients with nonischemic cardiomyopathy, potentially filling a current gap in clinical guidelines.

Background: Traditional prognostic risk assessment in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI) is based on a limited selection of clinical and imaging findings. Machine learning (ML) can consider a higher number and complexity of variables and may be useful for characterising cardiovascular risk, predicting outcomes, and identifying biomarkers in large population studies.

Methods: We prospectively enrolled 9,680 consecutive patients with coronary artery disease who underwent PCI at our institution between January 2013 and December 2013.

Article Synopsis
  • This study investigates the relationship between thyroid dysfunction and the occurrence of atrial fibrillation (AF) in patients with hypertrophic obstructive cardiomyopathy (HOCM), analyzing a cohort of 806 patients.
  • Results show that hypothyroidism is the most common thyroid condition among these patients, with higher rates of AF detected in individuals with both overt and subclinical hypothyroidism, along with significant differences in thyroid hormone levels between AF and non-AF groups.
  • The findings suggest that lower levels of free triiodothyronine (FT3), higher free thyroxine (FT4), and increased thyrotropin (TSH) levels are independently associated with a higher incidence of AF,

Background: Circumferential pulmonary vein isolation (CPVI) often cause unavoidable vagal reflexes during procedure due to the coincidental modification of ganglionated plexus which are located on pulmonary vein (PV) antrum. The right anterior ganglionated plexi (RAGP) which located at superoanterior area of right superior PV antrum is an essential station to regulate the cardiac autonomic nerve activities and is easily coincidentally ablated during CPVI. The aim of this study is to assess the effect of RAGP ablation on vagal response (VR) during CPVI.
