The difference between cardiac stenting and vascularization is that cardiac stenting refers to percutaneous coronary intervention as a treatment, while vascularization includes several treatments for coronary stenosis. Cardiac stenting, also known as percutaneous coronary intervention, is a treatment for coronary artery stenosis. It uses the femoral artery or radial artery route to deliver a guide catheter to the opening of the coronary artery to be dilated, and a balloon of the appropriate size is delivered to the narrowed blood vessel segment along the guide wire to be dilated with the appropriate pressure and time for the purpose of relieving the stenosis. Vascularization includes several treatments for coronary artery stenosis, including percutaneous coronary intervention, coronary artery bypass grafting, and thrombolysis, with cardiac stenting being one of the treatments for vascularization. If you have coronary artery stenosis, you should go to the hospital in time and choose a reasonable treatment plan under the evaluation of a specialized physician and under the guidance of the physician.
