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.
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.
It generally takes most people a couple of weeks to start returning to their normal activities after angioplasty/stenting. Before you leave hospital, you'll be given detailed instructions for exercise, medications, follow-up appointments, ongoing wound care and resuming normal activities.
What should you expect? The procedure may take place right after the arteriogram, which is used to find the blockage, or it may occur the next day. You may need to stay in the hospital two or three days.
As with all types of surgery, coronary angioplasty carries a risk of complications. However, the risk of serious problems is small. Complications can occur during or after an angioplasty. It's common to have bleeding or bruising under the skin where the catheter was inserted.
The meta-analysis showed that stents delivered no benefit over medical therapy for preventing heart attacks or death for patients with stable coronary artery disease. Still, many cardiologists argued, stents improved patients' pain. It improved their quality of life.
In most cases, you'll be advised to avoid heavy lifting and strenuous activities for about a week, or until the wound has healed.
General anesthesia isn't needed. You'll receive a sedative to help you relax, but you may be awake during the procedure depending on how deeply you are sedated. You'll receive fluids, medications to relax you and blood-thinning medications (anticoagulants) through an IV catheter in your hand or arm.
Watch for saturated fats in butter, cream, cheese, fatty red meat, and poultry skin. Trans fats can be found in fried and packaged foods — they contribute to high levels of unhealthy cholesterol. Refined and processed grains. Think white bread and white rice.
If you are having a heart attack, a stent is absolutely needed, stresses Donald Lloyd-Jones, M.D., chair of the Department of Preventive Medicine at the Northwestern University Feinberg School of Medicine in Chicago. Since a clot has completely blocked an artery, your heart muscle is starved of oxygen.
Usually, patients stay overnight and return home the day after the procedure. Some may even go home the same day. The amount of time that you stay in the hospital will depend on if there were any difficulties during the procedure and how well the catheter insertion site is healing.
Walking short distances on a flat surface is OK. Limit going up and down stairs to around 2 times a day for the first 2 to 3 days. Don't do yard work, drive, squat, carry heavy objects, or play sports for at least 2 days, or until your health care provider tells you it is safe.
The stent will expand when the balloon is inflated and remains in place when the balloon is deflated and removed. A coronary angioplasty usually takes between 30 minutes and 2 hours. If you're being treated for angina, you'll normally be able to go home later the same day or the day after you have the procedure.
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.
“Coffee is not recommended right after any form of cardiac surgery, including heart valve surgery.”
“This is because your artery has suffered some trauma and bruising from the stent being fitted. You can have episodes of pain or discomfort as the stent settles into place.
You will need to take antiplatelet medicines, or blood thinners, to prevent blood clots from forming in the stents in your arteries. 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.
Just after the procedure
Once your blood pressure, pulse, and breathing are stable and you are alert, you may be taken to the intensive care unit (ICU) or a regular hospital room. If the sheath was left in the insertion site, it will be removed from the groin or arm at the appropriate time.
Rule No 4: Moderate exercise after stenting procedure: No patient needs bed rest following stent implantation. It is advisable for patients to commence moderate exercise such as walking on the plain ground soon after angioplasty and gradually increase the intensity of exercise.
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.
They are made to be permanent — once a stent is placed, it's there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.
Heart attack or an angioplasty (stents)
Yes, you can drive after your doctor has told you it's safe to do so. You don't need to tell DVLA if you've had a heart attack or a coronary angioplasty. But you will be asked to stop driving for: 1 week if you've had a successful angioplasty and you don't need any more surgery.
Chest pain (angina) that worsens when you engage in physical activities. Shortness of breath that accompanies physical activity. Chest pain that doesn't improve when you've taken medication or made lifestyle changes.
Although stenting is technically more difficult than standard PTCA, it can be achieved with a high primary success rate (94% to 97%).
And this question has an answer—bypass surgery—as long as the individual's surgery risk isn't too high. "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.
