Cardiac stenting is minimally invasive surgery. Cardiac stenting, also known as percutaneous transluminal coronary artery stenting, involves delivering a balloon catheter through a puncture in a blood vessel on the hand or leg into a narrowed blood vessel. By pressurizing the balloon outside of the body, the balloon is allowed to expand to open up the narrowed blood vessel wall, allowing the blood vessel to reopen, and then a stent is placed to hold up the wall of the vessel to avoid elastic recoil and restenosis of the vessel. The interventional procedure can be completed under local anesthesia, which is less invasive, quicker recovery and less painful for the patient. Although cardiac stent surgery is a minimally invasive surgery, the requirements for the operator are relatively high, and the fineness of the instruments is also relatively high. After the surgery, the patient’s body is not able to fully recover, and still needs to insist on taking anti-platelet drugs, such as aspirin enteric-coated tablets, clopidogrel, and statin drugs, such as atorvastatin. After heart stent surgery, patients should take the medication on time as prescribed by the doctor and go to the hospital for regular checkups.
