Special Issue Information

Dear Colleagues,

We are pleased to introduce our upcoming Special Issue, which will explore the evolving role of antioxidants in cardiovascular medicine. Oxidative stress is increasingly recognized as a key contributor to the pathogenesis and progression of cardiovascular diseases (CVDs). As such, the potential of antioxidant-based therapies to mitigate oxidative damage and improve cardiovascular outcomes has garnered significant scientific and clinical interest.

This Special Issue aims to provide a comprehensive perspective on the latest advancements in antioxidant research, with a focus on novel compounds, molecular mechanisms, and clinical applications in CVD management. We welcome original research and review articles that address the following:

  • The role of oxidative stress and redox signaling in cardiovascular pathophysiology, including endothelial dysfunction, inflammation, myocardial remodeling, and vascular aging;
  • Innovative antioxidant therapies, including synthetic and natural compounds, targeted delivery systems, and combination approaches;
  • Preclinical and clinical evidence evaluating the efficacy of antioxidants in conditions such as atherosclerosis, hypertension, heart failure, and ischemic heart disease;
  • Dietary and lifestyle interventions that enhance antioxidant defenses and reduce cardiovascular risk;
  • Emerging biomarkers and novel methodologies for assessing oxidative stress and antioxidant efficacy in cardiovascular research;
  • The role of artificial intelligence (AI) and machine learning (ML) in predicting oxidative stress-related cardiovascular risks, personalizing antioxidant therapies, and analyzing large-scale omics data;
  • Computational modeling-and AI-driven drug discovery for the identification of new antioxidant compounds and their cardioprotective effects;
  • Big data analytics for evaluating population-based trends and the effectiveness of antioxidant-based interventions in real-world cardiovascular health.

By gathering contributions from experts across diverse fields, this Special Issue aims to bridge the gap between fundamental research and clinical applications, fostering a deeper understanding of antioxidant strategies in cardiovascular health. We encourage multidisciplinary perspectives, including insights from pharmacology, molecular biology, nutrition, artificial intelligence, and clinical medicine.

We look forward to your valuable contributions and to advancing the discussion on how antioxidant-based interventions, enhanced by AI-driven approaches, can shape the future of cardiovascular medicine.

Reactive nitrogen species (RNS), particularly peroxynitrite (ONOO), play a central role in post-translational modifications (PTMs) of proteins, including fibrinogen, a key component of the coagulation cascade. This review explores the structural and functional consequences of fibrinogen nitration, with a focus on its impact on clot formation, morphology, mechanical stability, and fibrinolysis. Nitration, primarily targeting tyrosine residues within functional domains of the Aα, Bβ, and γ chains, induces conformational changes, dityrosine crosslinking, and aggregation into high molecular weight species. These modifications result in altered fibrin polymerization, the formation of porous and disorganized clot networks, reduced mechanical resilience, and variable susceptibility to fibrinolysis. Moreover, nitrated fibrinogen may affect interactions with platelets and endothelial cells, although current evidence remains limited. Emerging clinical studies support its role as both a prothrombotic mediator and a potential biomarker of oxidative stress in cardiovascular and inflammatory diseases. Finally, we explore both pharmacological interventions, such as NOX inhibitors, and natural antioxidant strategies at counteracting fibrinogen nitration. Overall, fibrinogen nitration emerges as a critical molecular event linking oxidative stress to thrombotic risk. Full article
