Bare-metal stents (BMS) reduce the risk of re-occlusion and re-infarction after PCI,2,3 whereas early generation drug-eluting stents (DES) further decrease the risk of restenosis and target lesion revascularization without increasing the incidence of death or myocardial infarction in a broad spectrum of patients, …

Why would you use a bare metal stent?
The development of bare metal stents (BMS) was a major advance relative to balloon angioplasty in the management of symptomatic coronary artery disease. BMS prevented restenosis by attenuating early arterial recoil and contraction.
Is a bare metal stent drug-eluting?
Drug-eluting stent safety
In general, drug-eluting stents are less likely to cause restenosis than are bare-metal stents. A drug-eluting stent is the most common type of stent used to treat a blockage of the heart arteries.
Why are drug-eluting stents better?
These types of stents also lower your chances of your arteries narrowing again compared to other stents, angioplasty, or balloon treatment. Placing a stent is also less invasive with a shorter recovery time than a common type of open-heart surgery called coronary artery bypass surgery.
When is a bare metal stent used?
Bare-metal coronary artery stents are used in percutaneous coronary intervention (PCI) for a variety of indications, including stable and unstable angina, acute myocardial infarction (MI), and multiple-vessel disease.
What are bare metal stents made of?
Current bare metal stents (BMSs) are made of stainless steel, cobalt chromium, or platinum chromium. Stainless steel BMSs were the first devices used for coronary stenting.
What is the drug in a drug-eluting stent?
The first drug-eluting stents to be approved in Europe and the U.S. were coated with paclitaxel or an mTOR inhibitor, such as sirolimus.
What are the two types of stents?
There are two types of stents: bare-metal stent and drug-eluting stent. The latter are used more frequently and are coated with medication that helps keep a blocked artery open longer. The stent eventually becomes a part of the artery that it’s placed in.

How do bare metal stents work?
Bare-metal stents are tiny wire mesh tubes that help widen a clogged artery, but are not coated with a polymer or drugs to help prevent re-blockage of the artery. This type of stent may be used in patients who are allergic to either the polymer or drugs used in drug-eluting stents.
Why do drug-eluting stents require longer antiplatelet therapy?
1 Drug eluting stents (DES) are usually preferred over bare metal stents (BMS) because of less restenosis and fewer repeat revascularization procedures. However, DES require a longer duration of dual antiplatelet therapy to minimize the chance of stent thrombosis.
Are bare metal stents safe for MRI?
Despite emerging evidence that magnetic resonance imaging (MRI) is safe within 8 weeks after bare metal coronary stenting, there are limited data on the safety of MRI imaging very early (1 to 3 days) after stent implantation and no published studies to date on the safety of MRI after insertion of drug-eluting stents ( …
Are Xience stents MRI safe?
Non-clinical testing has demonstrated that the XIENCE Sierra stent, in single and in overlapped configurations up to 71 mm in length, is MR Conditional. It can be scanned safely under the conditions in the Instructions for Use.
Do magnets affect stents?
Conclusion: The magnetic force on the investigated paramagnetic stents is even smaller than the gravitational force acting on the stents in the Earth’s gravity field, so that it has no physiological impact on the stented vessels.
Why do you have to carry a stent card?
Patients with a stent can feel confident and safe when traveling. It’s important to carry your Medical Device ID card when traveling as it will alert medical and security personnel that you have an implanted stent.
Do stents set off metal detectors?
Because the stent is a foreign object in your coronary artery, you should receive a stent card that describes the type, date and location of the stent. You will not set off any metal detectors after stent implantation.
Do stents set off airport metal detectors?
No. A stent should not set off any metal detector or security screening. You will receive a wallet card with information about your stent after your procedure. You can keep that with you in the event there is any concern at security checkpoints.
Can you have a CT scan if you have a stent?
Mammography, CT scanning, x-rays and nuclear stress tests are considered safe for people with stents.
Do stents have metal?
There are different kinds of stents. Most are made of a metal or plastic mesh-like material. However, stent grafts are made of fabric. They are used in larger arteries.
What is a stent card?
Carry Your Stent Card
A stent card is a very handy way to do that. It’s a card that you carry in your wallet that tells the location of the stent in your body, the date of your procedure when you received the stent and your doctor’s name and contact information.
Can a stent dislodge?
Stent dislodgement can occur due to arterial tortuosity and calcification, direct stenting, or the inadequate coaxiality of the guide catheter; therefore, adequate predilation may help to prevent stent dislodgement.
How many years does a stent last?
How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months.
Do stents ever collapse?
Immediate collapse of implanted coronary stent is a rare complication, and, to our knowledge, few authors have reported it previously. Current stents on the market are thought to have sufficient radial strength against the external coronary artery strain .
How many stents can a person have 2020?
Patients Can’t Have More Than 5 To 6 Stents In Coronary Arteries: A Myth.
Can you stent a 100% blocked artery?
“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”
What is the most number of stents?
