A drug-eluting stent is coated with a slow-release medication to help prevent blood clots from forming in a stent.<\/p>\n<p>Blood clotting in a stent can cause a future blockage, called restenosis, and may lead to a heart attack.<\/p>\n<p>Stents without a drug coating are called bare-metal stents.<\/p>\n<p>Today, new and better versions of drug-eluting stents are available. These stents are safe and effective for most people when used with anti-clotting medicines as prescribed. In general, drug-eluting stents are less likely to cause blockages than are bare-metal stents.<\/p>\n<p>A drug-eluting stent is the most common type of stent used to treat a blockage of the heart arteries. Many people with heart problems have been successfully treated with drug-eluting stents. Use of these stents may prevent the need for more-invasive procedures, such as coronary artery bypass surgery.<\/p>\n<p>A heart doctor, called a cardiologist, places a stent during coronary angioplasty, also called percutaneous coronary intervention. In this procedure, a thin, flexible tube, called a catheter, with a balloon on the tip is put in a blood vessel. The balloon is inflated for a short time to widen the blocked artery and help blood flow. Sometimes, a drug-coated balloon is used.<\/p>\n<p>For chest pain due to a blocked heart artery, a drug-eluting stent can lower the symptoms. It also may prevent the need for more angioplasty procedures.<\/p>\n<p>A drug-eluting stent may not be a choice for people with a history of bleeding problems. That&#8217;s because aspirin and a prescription blood thinner such as clopidogrel (Plavix) must be taken. This is to help stop blood from clotting in the stent. Having a drug-eluting stent might mean taking a daily aspirin for life.<\/p>\n<p>A healthcare professional can give more instructions on what to expect before and after drug-eluting stent placement. Some things to consider are:<\/p>\n<ul>\n<li><strong>Needing another type of surgery soon.<\/strong> A healthcare professional might recommend waiting to have noncardiac surgery for one year after getting a drug-eluding stent. Noncardiac surgery is any surgery not related to the heart. For those who can&#8217;t wait to have surgery, a bare-metal stent may be a better choice.<\/li>\n<li><strong>Needing a change of medications.<\/strong> Blood thinners and aspirin can have an effect on surgeries, some medical procedures and some medicines. If a noncardiac surgery can&#8217;t be postponed, a healthcare professional might change the dose of anti-clotting medicines and aspirin. It also might be possible to stop taking anti-clotting medicines six months after stent placement, but only with the approval of a care team.<\/li>\n<\/ul>\n<p>After you&#8217;ve received a drug-eluting stent, a health care provider prescribes medications, such as aspirin and statins, and lifestyle changes to prevent stent or heart problems. Healthy lifestyle changes include stopping smoking, eating a more heart-healthy diet and getting plenty of exercise.<\/p>\n<p>For some people, coronary bypass surgery may be done instead of stent placement. Coronary bypass surgery works well, but it&#8217;s more invasive than using stents, which means a longer recovery time.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Stents coated with a slow-release drug are safe when used with proper medications.
