Abstract
Obesity is a complex, multifactorial disease wherein the excessive accumulation of adipose tissue leads to adverse health outcomes, such as diabetes, cardiovascular disease and musculoskeletal disorders. Obesity also impacts both the risk and the clinical prognosis of heart failure (HF). The accumulation of adipose tissue results in metabolic dysregulation, including increased levels of pro-inflammatory cytokines and adipokines. These alterations are strongly associated with the development and progression of HF. Another significant comorbidity in patients with HF is sarcopenia, characterized by progressive loss of muscle mass and strength, affecting the quality of life. The study aims to critically synthesize the mechanisms by which modern pharmacological treatments-sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor (GLP-1R) agonists, and dual GIPR/GLP-1R agonists-modulate body mass composition, and to analyze the specific implications of these changes (e.g., visceral fat reduction versus lean mass loss) for heart failure (HF) prognosis and management.
