If you have other medical conditions such as multiple narrowed coronary arteries, kidney disease that is long-lasting, or diabetes, stents may not be recommended. Your provider may recommend coronary artery bypass graft surgery (CABG) instead.
The greatest risks from a stent occur when patients do not take medications as prescribed. If you have a bare metal stent, then you will have to take medications for at least one month to prevent blood clots from forming in the stent.
The most widely used surgical alternative to a coronary angioplasty is a coronary artery bypass graft (CABG).
“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.”
Results show that managing the condition with beta blockers, calcium blockers, statins, aspirin therapy, and forms of nitroglycerin can allow more patients to avoid common and invasive bypass or stent procedures.
By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. "A 50 percent blockage doesn't need to be stented," he said.
In a small percentage of patients with stents, blood cells can become sticky and clump together to form a small mass – or clot. When a blood clot forms, it can block the free flow of blood through an artery and may cause a heart attack or even death.

Many times people live happily with a blocked artery. But with one blocked artery symptoms are a high chance of reduced life expectancy. Asymptomatic patients live up to 3-5 years.
"For three-vessel coronary disease, bypass now has been shown to be superior to stenting, with the possible exception of some cases in which the narrowing in the artery is very short," Cutlip says. "But by and large the debate is settled that bypass surgery is better."
damage to the artery where the sheath was inserted. allergic reaction to the contrast agent used during the procedure. damage to an artery in the heart. excessive bleeding requiring a blood transfusion.
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.
Examples include aspirin, clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta). It is critical that these medicines not be stopped without checking with your cardiologist, for stopping them prematurely can result in another heart attack from the stent closing off abruptly.
Symptoms like fatigue, chest pain or shortness of breath can indicate in-stent restenosis. If you experience symptoms, you should contact your healthcare provider. Newer, safer drug-eluting stents can lower your risk of developing in-stent restenosis.
It depends primarily on the underlying heart disease, age, and medical condition of the patient. A younger patient, for example, who has a strong heart and has never experienced a heart attack, will be expected to live a full and active lifespan.
Stenting is a minimally invasive procedure, meaning it is not considered major surgery. Stents can be made of metal mesh, fabric, silicone, or combinations of materials. Stents used for coronary arteries are made of metal mesh. Fabric stents, also called stent grafts, are used in larger arteries such as the aorta.
Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur.
In vitro (15–19) and animal (19–23) studies suggest biological mechanisms through which magnesium may prevent or reverse plaque formation and calcification.
In summary, fish oil may reduce atherosclerosis by activating numerous nuclear receptors including PPAR-alpha and PPAR-gamma, by inhibiting the infiltration of macrophages and as the release of MMPs, and by preventing the weakening and rupturing of atherosclerotic plaque.
A: Yes. There have been several clinical studies — many of them done here at Cleveland Clinic — that show statins can reverse plaque buildup. Two statins in particular, atorvastatin, which is sold under the brand name Lipitor, and rosuvastatin, which is sold under the brand name Crestor, are the strongest statins.
The use of stents has been growing continuously beyond these indications, and today stents are a ubiquitous routine in interventional cardiology. Although stenting is technically more difficult than standard PTCA, it can be achieved with a high primary success rate (94% to 97%).
Stents will last forever if they are made of some sort of metal as most are. There is a new product on the market, a new heart stent that dissolves in the artery three years after being implanted. It is yet to be used in clinically, and it will be a while (years) before its risks & benefits will be known.
Myth: The angioplasty procedure and stent fixed my heart problems. Fact: You should feel better immediately after your angioplasty because it opened your blocked blood vessel and blood started to flow freely.
