They are used to keep narrowed arteries, which can help reduce (English) heart symptoms or general chest pain.. Used when the coronary arteries are narrowed. Cardiac stents are small and openable tubes that are also called coronary stents or cardiac springs. There are different types of coronary stents, which include the following:

- Bioengineered stents - Absorbable vascular clamp (BVS) - Drug-eluting stents (DES) - Dual treatment stent (DTS) - All metal stents (BMS)

### **bioengineered stents** These types of stents, which are also known as stents covered with antibodies, help to increase the speed of treatment of the cellular path of the artery and thus increase the speed of natural healing... In bioengineered stents, polymers and drugs are not used, but there is antibody on their surface... The use of these stents helps to reduce the risk of thrombosis (block)... The surface of these stents is composed of drugs that prevent the growth of scar tissue in the path of the free artery. Blood clot formation is one of the disadvantages of these types of stents, but on the other hand, it helps maintain blood flow and reduce the possibility of narrowing and re-occlusion.. (DTS) Dual therapeutic stent is a coronary artery stent which is the newest type of coronary stent. These stents are a combination of bioengineered stent technology and drug stents designed to reduce the chance of re-narrowing of the artery and reduce the need for repeat surgery. As a result, dual therapeutic stents are used to reduce the need for surgery. They have long been developed for dual antiplatelet therapy. They improve cellular... ### **absorbable vascular occlusion (BVS) As its name suggests, these types of stents are absorbable and are absorbed by the human body over time. Vascular clamps are a type of medical stent that reduce the risk of narrowing and re-narrowing of the vessels... ### All metal stents (BMS) The structure of these stents is made of stainless steel and does not have any other coating, including drug coating.... These stents are used to keep blood vessels open after angioplasty.... These types of stents may have more degrees of narrowing, but they do not require the long-term use of anti-platelet drugs.... Also, the use of this stent is preferred in the first stage in people who are at high risk of bleeding. It goes to the blockage.... - Then the balloon is opened and the stent expands.... which causes the stent to be placed inside the artery.... After placing the stent, the balloon and the catheter (guide tube) are removed from the body... Complications of using a cardiac stent In the stenting method, like other surgeries, you may face risks and complications. These risks include the following: - Allergic reaction - Bleeding - Abnormal heartbeat or cardiac arrhythmia - Renal failure - Vein narrowing and blockage - Blood clots in the stent Care and tips after cardiac stenting - Depending on whether the stent is drug-coated or not, it will be completely covered with tissue within 3 to 12 months.... - Antiplatelet drugs may be prescribed to reduce the "stickiness" of platelets.... This drug can also prevent blood clots from forming inside the stent.. Stenting.. After stenting, usually **diluting drugs such as aspirin** Plavix is ​​prescribed by the attending physician to **reduce the risk of clotting** at the stent site... but in case of side effects such as: bleeding and inflammation at the catheter insertion site, chest pain, shortness of breath, fainting and weakness, change in the color of the hands, consult a doctor, etc.
