Why would you need a stent in your heart?
Your coronary arteries play a vital role in keeping your heart healthy. But in some people, fatty deposits can build up and narrow or block the coronary arteries (this is called atherosclerosis, which can cause coronary heart disease). If not enough blood is flowing through the coronary arteries, this can lead to angina or a heart attack.
Coronary angioplasty widens narrowed coronary arteries. This procedure is used:
- in severe cases of angina, where medicine is not working
- as an emergency treatment for people during a heart attack.
Angioplasty is not for everyone. Depending on your health and individual heart conditions, you may be advised that you need coronary artery bypass surgery.
How successful is angioplasty and stenting?
In most cases coronary angioplasty and stenting improves the blood flow through the treated artery. Many people find their symptoms get better and they’re able to do more.
Sometimes the artery can become narrowed again (restenosis), causing angina symptoms. But advances in stent technology mean that the risk of this happening is getting lower. Many people are now symptom-free for a long time.
You can improve your chances of long-term success by making healthy lifestyle changes, including:
A small number of people may have coronary angioplasty complications. The risk varies depending on your overall health and your individual heart condition.
What are the benefits of coronary angioplasty and stents?
The benefits and risks of angioplasty and stenting are different for everyone and depend on the seriousness of your heart disease, your age, and your overall health. The benefits of angioplasty and stenting can include:
- relief from or less pain
- relief from or less breathlessness
- relief from or less tiredness
- more energy – with better blood flow to your heart, everyday tasks and physical activities become easier and more enjoyable
- better mood and mental health
- a reduced risk of heart attack and stroke.
Have a chat with your doctor about the benefits and possible risks of having an angioplasty and make sure to mention any concerns you may have.
What are the risks of coronary angioplasty and stents?
All types of medical procedures come with risk. With angioplasty and stenting, common complications can include:
- bleeding, bruising, or an infection where the catheter tube is put into the body (in the wrist or groin)
- blood clots – these can form within stents even after the procedure, so it’s important to take any prescribed medicine such as aspirin and anti-platelet drugs such as clopidogrel.
The risk of major complications during an angioplasty is usually less than one percent. Rare risks of angioplasty and stenting include:
- complications after or during the procedure, such as a heart attack or stroke
- an allergic reaction to the contrast dye used during the procedure
- very rarely damage to the coronary artery during the procedure.
If you’re worried or have more questions, we encourage you to ask your doctor. They’ll be able to answer any questions specific to you and your procedure. You can also download or order our booklet, Understanding coronary angioplasty.
How to prepare for angioplasty and stents
If your doctor recommends having an angioplasty and stents, ask them any questions you may have about it. You can then begin to prepare for the procedure, which can help reduce any stress and anxiety you may feel. Preparation may include:
Being as prepared as possible before surgery can help speed up the time it takes to recover. It can also help you feel less worried. Read our 5 top tips on getting in shape before a procedure.
Heart stent recovery: what happens after angioplasty?
Most people can go home the same day or the next day, but if you’ve had an emergency angioplasty after a heart attack it’s likely you’ll need to stay in hospital for longer.
When you get home, check the area where the catheter tube was put in. Expect to have some bruising and tenderness, but you should contact your doctor if:
you get any pain, redness or swelling.
- the bruising worsens
- you develop a temperature.
Before you leave hospital, someone will have a chat with you about your recovery and what you can and cannot do. It’s normal to feel tired afterwards but most people find that they’re back to normal after a few days. However, if you’ve also had a heart attack, it will take longer to recover.
If you’ve had a stent fitted, you’ll be given medicines to help reduce the risk of blood clots forming in and around the stent. They may include:
- aspirin
- anti-platelet medication such as clopidogrel, ticagrelor or prasugrel.
You may also be asked to take cholesterol-lowering drugs such as statins.
If you’ve had an emergency angioplasty, you may be invited to go on a cardiac rehab programme, a course of exercise and information sessions that help you to recover as quickly as possible.
It can feel worrying to have a stent fitted, especially if you’ve had an emergency angioplasty. But many people find recovering from angioplasty is a positive moment to make healthy lifestyle changes that will improve your health and everyday life.
Before you leave hospital, someone will have a chat with you about your recovery and what you can and cannot do. It’s normal to feel tired afterwards but most people find that they’re back to normal after a few days. However, if you’ve also had a heart attack, it will take longer to recover.
Is chest pain normal after a stent placement?
It is possible that you are experiencing discomfort because the stent is taking time to settle. This is quite normal, but you may want to make an appointment to see your GP and check if they want to review your medicines.
A stent will help blood flow in the artery where it has been fitted and will usually improve symptoms of angina. But sometimes other heart arteries can be narrowed too, so you may still have some angina symptoms.
If you get chest pain, stop and rest, and take your GTN if you've been prescribed it. The pain should go away within five minutes. If it does not, take your GTN again.
If the pain has not gone away within five minutes of taking the second dose of GTN, call 999 immediately. You could be having a heart attack.
What to avoid after a stent
How long should you rest after a stent placement?
If you’ve had a planned stent placement, it’s best to avoid doing any demanding activities, such as heavy lifting, for a week or so afterwards.
You may need longer if you’ve had an emergency angioplasty or a heart attack – chat with your doctor to find out what’s right for you.
When can you return to work after a stent?
If you’ve had a planned angioplasty with no complications you may be able to return to work within a few days, depending on the type of work you do.
If you’ve had an emergency angioplasty or a heart attack you may need to take a few weeks off.
You should chat about your own situation with your doctor or nurse.
How long after a stent can you drive?
You should not drive for at least a week after having an angioplasty and stent - longer if you also had a heart attack.
Check with your doctor to see how soon you can drive after having a heart attack and stent. You may need to wait up to 4 weeks.
If you drive a heavy vehicle for a living, such as a lorry or a bus, you must tell the Driver and Vehicle Licensing Agency (DVLA) that you've had a coronary angioplasty. They'll arrange further testing before you can return to work.
How soon can you fly after having a stent fitted?
It’s not generally recommended to take a long-haul flight soon after having a stent fitted but if you are generally well, and have talked through your situation with your doctor, you may be fit to fly:
- 2 days after a planned, uncomplicated angioplasty
- 3 to 10 days after an uncomplicated heart attack
- 4 to 6 weeks after a complicated or major heart attack.
Stents are not affected by security systems at airports or MRI scans.
Can you have sex after stents in your heart?
It's normal to feel anxious about having sex if you have a heart condition. But there's no reason why you cannot continue to enjoy a healthy sex life, once you've recovered from having an angioplasty and stent fitted.
In fact, some people who were previously affected by angina, find they are able to have a more active sex life as they have more energy after an angioplasty and stent.
Your doctor will have talked to lots of other people about sex. You will not be the first or the last person to ask. It may not be easy to talk about at first, but most people say they feel a lot better afterwards and are glad they did.
Get support
As the day of your angioplasty and stent fitting gets closer, you may feel anxious, afraid, angry, worried about the future, or glad that you’re about to have treatment.
It’s natural to have these feelings and you may continue to have them after the procedure. It’s important to talk about your feelings with your partner, a friend, relative or healthcare professional.
