Key result
Semaglutide demonstrates robust cardioprotective and vasculoprotective effects but requires clinical vigilance for potential cardiotoxicity.
Why the study?
Further research is needed to better understand the effects of semaglutide on cardiac function and pathologies as it advances as a cardiac drug.
Semaglutide offers significant cardioprotective and vasculoprotective benefits through multiple molecular pathways, though clinicians must remain vigilant for potential cardiotoxicities such as arrhythmias.
May warrant arrhythmia monitoring with semaglutide; leaves open whether pathway effects yield net clinical benefit.
Semaglutide, a recombinant DNA-derived long-acting GLP-1 receptor agonist, has emerged as a key player for patients with or without T2DM and obesity. It exerts pleiotropic effects by modulating glycemic regulation and energy homeostasis. Mechanistically, it stimulates glucose-dependent insulin secretion and suppresses glucagon while enhancing satiety through POMC/NPY modulation in the arcuate nucleus and delaying gastric emptying. Beyond its metabolic utility, semaglutide is cardioprotective, leveraging the PI3K/Akt and eNOS pathways to improve vasodilation, reduce reactive oxygen species (ROS), and stabilize atherosclerotic plaques by inhibiting pro-inflammatory cytokines like TNF-α. While it improves cardiac output via PKA-mediated inotropy, potential cardiotoxicity, including resting tachycardia and autonomic-driven arrhythmias, requires clinical vigilance, particularly regarding electrolyte imbalances in heart failure patients. Ultimately, its robust vasculoprotective profile reinforces its potential as a cornerstone in cardiovascular pharmacotherapy. Further research is needed to better understand the effects of semaglutide on cardiac function and pathologies as it advances as a cardiac drug. This review discusses multiple molecular targets of semaglutide on the heart.
