Many heart patients who have gone through stenting procedures have this doubt in their minds. So, without a long post to read, let us come straight to the answer that is, yes. You can get a heart attack again even after you have undergone a cardiac stenting procedure.
Yet, about one in five people who have had a heart attack will be readmitted to the hospital for a second one within five years. Each year, there are about 335,000 recurrent heart attacks in the United States. A heart attack is damaged or dying heart muscle caused by a blockage of the blood supply to that area.
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. If it does, it can potentially be treated with another stent.
People who undergo angioplasty and stenting to treat coronary artery disease may develop in-stent restenosis. Scar tissue forms under the stent, causing a previously opened coronary artery to narrow again. You need another angioplasty or heart bypass surgery to correct the problem.
Blood clots can form within stents even after the procedure. These clots can close the artery, causing a heart attack.
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.
In many cases, doctors insert a coronary artery stent after an angioplasty. The stent helps keep the blood flowing and the artery from narrowing again. Having an angioplasty within the first hours after a heart attack may reduce your risk of complications. Timing can be crucial.
As recommended in the National Disease Management Guidelines (6), patients with coronary heart disease and those who have undergone stent implantation should be followed up regularly (every three to six months) by their primary care physicians, independently of any additional visits that may be necessitated by ...
The stent will usually improve the symptoms of angina, but there may be narrowings in other arteries too. These might not be severe enough to require another stent, so you may still have angina symptoms – this is why working with your doctor to get your medication right is so important.
Conclusions—Nonischemic chest pain develops in almost half of all patients undergoing stent implantation and seems to be related to vessel overexpansion caused by the stent in the diseased vessel segment.
Sometimes heart problems return after a stent procedure. If that happens, you usually have symptoms—like chest pain, fatigue, or shortness of breath. If you do have symptoms, a stress test can help your doctor see what's going on. It can show if a blockage has returned or if there's a new blockage.
One can go back to their normal routine within 2 to 3 days after undergoing the procedure, depending on the doctors' recommendations. However, patients who undergo this procedure must ensure they follow the above-mentioned lifestyle changes to lead a long and healthy life after stent placement.
A stent is a small mesh tube put into an artery to keep it open. A drug-eluting stent is coated with a slow-release medication to help prevent blood clots from forming in a stent. Blood clotting in a stent can cause a future blockage (restenosis) and may lead to a heart attack.
Every year, about 805,000 people in the United States have a heart attack. Of these, 605,000 are a first heart attack. 200,000 happen to people who have already had a heart attack.
Risk Factors for a Second Heart Attack
Risk factors for another attack include: Unhealthy diet: Your diet has a major impact on weight, cholesterol levels, blood sugar, and more. Physical inactivity: Some people worry that they shouldn't exercise after a cardiovascular event, but the opposite is true.
Your provider may prescribe these medicines for 1 year or more after getting a coronary stent. For carotid or peripheral artery stents, it may be 1 month or more. Antiplatelet medicines include aspirin, clopidogrel, dipyridamole, and ticlopidine.
In short, the answer is no. Once a stent is opened in an artery, the tissue cells of the artery wall begin to grow over the stent. The stent becomes a part of the artery wall and cannot move.
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.
A stent can cause blood clotting, which may increase the risk of heart attack or stroke. The National Heart, Lung, and Blood Institute state that about 1 to 2 percent of people who have stented arteries develop a blood clot at the site of the stent. Doctors will usually prescribe one or more drugs to prevent clotting.
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.
Stress increases the plaque rate and it can accumulate in the arteries. It makes platelets sticky and prone to forming clots that can block these arteries. Stress can also cause arteries to constrict, starving the heart of nourishing blood and triggering chest pain or a heart attack.
About 1 in 5 people who have had a heart attack will be readmitted to the hospital for a second one within five years, according to the American Heart Association.
The two major causes of stent failure are stent thrombosis (ST) and in-stent restenosis (ISR). The incidence of both has reduced considerably in recent years.
Summary: While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that stents have no impact on mortality over the long term.
