Abstract

Percutaneous coronary intervention (PCI) is the main treatment for patients with severe coronary vascular stenosis. However, In-stent neo-atherosclerosis (ISNA) is an important clinical complication in patients after PCI, which is mainly caused by a persistent inflammatory response and endothelial insufficiency. In the cardiovascular field, magnesium-based scaffolds stand out due to their properties. Magnesium plays a key role in regulating cardiovascular physiology. Magnesium deficiency can promote endothelial cell dysfunction, which contributes to the formation of atherosclerosis. Since astragaloside IV (AS‑IV) has been proven to have potent cardioprotective effects, we asked whether high levels of magnesium cooperate with AS‑IV might have effects on endothelial function and ISNA. We performed in vitro experiments on endothelial cells. Being treated with different concentrations of magnesium or/and AS-IV, the cell growth and migration were detected by CCK-8 and wound healing assay, respectively. The pro-inflammatory factors tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), adhesion molecule vascular cell adhesion molecule-1 (VCAM-1), and NF-kB were determined by qRT-PCR, ELISA kits or western blot. Results showed that high magnesium and AS-IV improved endothelial function, including promoting cell migration and decreasing the content of TNF-α, IL-6, VCAM-1, and NF-kB. With the supplement of AS-IV, additive magnesium maintains cell proliferation, migration, and function of endothelial cells. In conclusion, these findings suggest that high magnesium and AS‑IV could improve vascular endothelial dysfunction. Early detection and treatment for neo-atherosclerosis may be of great clinical significance for improving stent implantation efficacy and long-term prognosis.
