Drug-eluting coronary stent system usually refers to the use of bare metal stent platform to carry anti-intimal hyperplasia drugs to inhibit stent intimal hyperplasia. The drug-eluting coronary stent system can elute locally in the vasculature to release the drug-carrying, which can inhibit stent intimal hyperplasia, thus preventing stent restenosis and effectively reducing the incidence of restenosis and reoperation, and the drug-carrying mainly includes paclitaxel, everolimus, and barilimus. The drug-eluting coronary stent system can selectively inhibit endothelial proliferation and can effectively prevent in-stent restenosis. If you need to undergo coronary stenting, please go to a regular hospital and take regular medication as prescribed by your doctor after the procedure.
