In recent decades, the novel role of Galectin-3 (Gal-3) in both physiological and pathological conditions has emerged. Gal-3 is a key protein involved in immunity, inflammation, cell adhesion, proliferation, differentiation, and apoptosis. Its physiological role is crucial for the regulation of these cellular functions. In pathological settings, elevated levels of Gal-3 are associated with diseases such as cancer, heart failure, and fibrotic diseases, making it an important diagnostic and prognostic biomarker in these conditions. It seems that Gal-3 acts as a bridge between different diseases. Because of its pro-inflammatory and pro-tumorigenic properties, it connects atherosclerosis and cancer, regulating inflammation, cell proliferation, immune evasion, angiogenesis and survival in both diseases. Specifically, in atherosclerosis, Gal-3 promotes plaque formation by driving inflammation, oxidative stress, lipid deposition, and vascular cell migration. In cancer, Gal-3 influences tumor growth and metastasis by modulating an immunosuppressive tumor microenvironment, increasing cell survival, and enhancing cell–matrix and cell–cell interactions. Moreover, by stimulating fibroblasts, Gal-3 favors matrix deposition and tissue fibrosis that together with the inflammatory properties contributes to adverse ventricular remodeling leading to heart failure. Finally, taking into account its role in pathogen recognition and immune cells (B and T cells) modulation, Gal-3 might be a critical factor in host defense, disease progression, and the development of autoimmune conditions. Thus, targeting Gal-3 might be a promising therapeutic strategy to pursue for management of different pathological scenarios.

Cardiovascular diseases represent one of the leading causes of morbidity and mortality worldwide despite tremendous advancements in therapeutic interventions. Prevention remains one of the most effective strategies to reduce individual risk. Apolipoprotein E (ApoE), through its genetic variants (ε2, ε3, ε4), is a well-known modulator of cardiovascular risk, traditionally studied for its role in lipid metabolism. However, recent evidence suggests that ApoE also influences endothelial function and thrombotic processes, opening new perspectives for an integrated approach to risk assessment. This narrative review explores the potential of using the APOE genotype as a key genetic biomarker, integrated with emerging endothelial markers (e.g., plasma levels of endothelin-1, nitric oxide, von Willebrand factor, endothelial adhesion molecules) to achieve a more accurate and personalized stratification of cardiovascular and thrombotic risk. The combined approach may overcome the limitations of traditional thrombophilia screening, which is often poorly informative when performed without clear clinical criteria, and may guide more targeted therapeutic decisions, particularly in borderline-risk individuals or those with unexplained thrombotic events. Finally, the review discusses the clinical implications, current challenges, and future perspectives for integrating this model into clinical practice within the framework of precision medicine. The early identification of genetically predisposed patients, together with functional endothelial assessment, could represent a breakthrough in modern cardiovascular prevention.

Background: Obesity has been defined as a true worldwide “pandemic” by the World Health Organization and represents one of the major public health problems. It is associated with a reduction in life expectancy of about 7–8 years due to related cardiovascular diseases such as arterial hypertension, metabolic syndrome, insulin resistance, type 2 diabetes mellitus, and dyslipidemia. Adipose tissue is not merely a fat storage site but a true endocrine and immunologically active organ that secretes hormones and mediators (adipokines), influencing cardiovascular risk and host physiology. Objective: This review summarizes the current understanding of the role of epicardial adipose tissue (EAT) in cardiovascular disease pathophysiology and discusses its clinical diagnostic and therapeutic implications. Methods: A narrative non-systematic review was conducted focusing on recent literature concerning the biological and clinical aspects of cardiac adipose tissue, with particular emphasis on epicardial adipose tissue. The review examined its gene expression profile, secretory function, and interaction with cardiovascular structures and diseases. Findings: There are different types of adipose tissue, including cardiac adipose tissue, which comprises epicardial and pericardial (or paracardiac) fractions. Epicardial adipose tissue is unique due to its proximity to the heart and a distinct gene expression profile compared to other adipose depots such as visceral and subcutaneous fat. EAT plays a crucial role in the development and progression of cardiovascular diseases with high morbidity and mortality, acting both as a metabolic and inflammatory mediator. Conclusion: Cardiac adipose tissue, particularly EAT, is a key player in cardiometabolic disease. Understanding its pathophysiological role and incorporating imaging tools to evaluate EAT may enhance cardiovascular risk stratification and disease management.

Lipoprotein(a) [Lp(a)] has emerged as a major genetically determined cardiovascular risk factor that extends beyond the traditional low-density lipoprotein cholesterol (LDL-C)-centred model of atherosclerotic disease. Despite optimal LDL-C lowering, a substantial proportion of patients continue to experience cardiovascular events, highlighting the clinical relevance of residual cardiovascular risk. This review summarizes current evidence regarding the epidemiology, genetics, pathophysiology and therapeutic implications of Lp(a) in cardiovascular disease. Epidemiological, genetic, and Mendelian randomization studies consistently demonstrate an independent and likely causal association between elevated Lp(a) and atherosclerotic cardiovascular disease, ischemic stroke, calcific aortic valve stenosis, heart failure, and recurrent cardiovascular events, even in patients with well-controlled LDL-C levels. Lp(a) promotes atherosclerosis through proatherogenic, proinflammatory, and prothrombotic mechanisms, largely mediated by oxidized phospholipids and the structural homology of apolipoprotein(a) with plasminogen. Current guidelines increasingly recognize Lp(a) as a risk-enhancing factor capable of refining cardiovascular risk stratification beyond traditional algorithms, thus recommending measuring Lp(a) at least once in a lifetime in all adults. Accurate measurement and standardization of Lp(a) remain essential in clinical practice due to apo(a) isoform size variability; reporting in molar concentrations (nmol/L) is preferred as it better reflects particle number being less affected by isoform size variations and improves the reliability of cardiovascular risk stratification. Collectively, these findings support the integration of Lp(a) into precision-based cardiovascular prevention strategies and suggest a paradigm shift from an exclusively LDL-centric approach toward genetically informed risk assessment and treatment.
