Coronary stents do not have to be removed after implantation, but oral medication is needed to prevent blood clots from forming. Coronary stenting is one of the treatments for coronary artery stenosis. Types of stents include bare metal stents, drug-eluting stents, and absorbable biologic stents. After the stent is inserted into the coronary artery, the endothelial cells will migrate and gradually cover the stent so that the stent and the blood vessel will fuse together as one, and therefore there is no need to remove the stent after the procedure. However, it should be noted that after stenting, there is still a risk of thrombosis and restenosis, so after stenting, it is necessary to strictly follow the doctor’s instructions to take antiplatelet drugs, such as aspirin and clopidogrel, as well as lipid-regulating therapy. In addition, people with hypertension and diabetes also need to follow the doctor’s instructions to lower blood pressure and control sugar treatment. Stent implantation only relieves previous stenosis, but does not prevent future stenosis. Therefore, after the operation, you should follow the doctor’s instructions to take medication regularly, and you should pay more attention to your own life and have regular checkups.
