Mechanisms of ferroptosis and glucagon-like peptide-1 receptor agonist in post-percutaneous coronary intervention restenosis

Cardiovascular disease (CVD) claims millions of lives every year, with atherosclerotic cardiovascular disease (ASCVD) being the main cause. ASCVD treatment includes drug therapy, lifestyle intervention, and Percutaneous Coronary Intervention (PCI) all of which significantly enhance cardiovascular function and reduce mortality. However, hyperplasia can lead to vascular obstruction, worsen angina symptoms, or even cause heart disease, affecting patients' long-term prognosis. Therefore, finding effective ways to combat hyperplasia is crucial for cardiovascular therapy. In recent years, ferroptosis has gained attention as a new form of cell death closely associated with several diseases, including cardiovascular diseases. It involves complex metabolic processes critical for cellular homeostasis and normal function. Abnormal proliferation and phenotypic transformation of vascular smooth muscle cells (VSMC) are crucial mechanisms underlying cardiovascular disease development. Inhibiting ferroptosis in VSMC has the potential to significantly reduce neointima proliferation. Glucagon-like peptide-1 receptor agonist (GLP-1RA) constitutes a widely employed class of hypoglycemic agents with direct implications for the cardiovascular system, mitigating adverse cardiovascular events. Research indicates that the stimulation of GLP-1 holds promise as a therapeutic strategy in mitigating cardiovascular events such as restenosis. Hence, investigating the potential of GLP-1RA as a treatment option for cardiovascular ailments carries immense clinical significance.
