Heart Disease: Should I Have Angioplasty for Stable Angina?
Get the facts
Your options
- Have angioplasty for stable angina, along with
taking medicines and making healthy lifestyle changes.
- Take
medicines and make lifestyle changes to treat stable angina. This is called
medical therapy.
Key points to remember
- Medical therapy (medicines and lifestyle changes) and angioplasty work about
the same at preventing
heart attacks and helping people live longer. There is
no evidence to show that angioplasty for stable heart disease will help you live any longer than medical
therapy. Also, angioplasty
does not lower the risk of having a heart attack any more than medical therapy
does.
- Angioplasty can relieve angina symptoms if medical therapy has
not stopped your symptoms. This may help you have a more active
life.
- If you choose angioplasty, you will still need to make
lifestyle changes. This will give you the best chance for a longer, healthier
life.
- Angioplasty carries the risk of heart attack,
stroke, and even death. These rarely happen. But you
may not want to take even the small risk of dying from the procedure if you
have an equally small risk of dying without it.
- If you decide to
try medical therapy now, you can still have angioplasty later if your angina symptoms bother you too much.
- The benefits of angioplasty
may not last. The repaired artery can become blocked again over time. You may
need another procedure.
FAQs
Choosing a treatment may seem like a decision that your doctor should
make. But you can take part in this important choice if:
- You have mild heart disease. This means that
you do not have too much narrowing of the arteries that send blood and oxygen
to your heart (coronary arteries). It also means that your risk of
having a heart attack is not too high.
- You have stable angina.
This means your angina symptoms, such as chest pain or discomfort, happen with emotional or physical stress and go
away when you rest or after you take
nitroglycerin.
Your doctor can tell you if you meet these
conditions.
You will want to talk to your doctor about angioplasty
before you have a coronary angiogram (also called cardiac catheterization). During that test, you will not be able
to take part in the decision about angioplasty, because you will be sleepy from
medicines. So before the test, talk with your doctor about what the test might
show and what the doctor's options are in each case. You can tell the doctor in
advance what you would prefer, based on the test results.
During
angioplasty, the doctor puts a thin, flexible tube
called a catheter into an artery in your groin or arm. The doctor guides the
tube into the narrowed artery. He or she inflates a small balloon at the end of
the tube. This widens the artery to allow blood to flow. The doctor may put a
small, expandable tube called a
stent in the artery to keep it open.
After
angioplasty, you will need to follow a heart-healthy diet and get plenty of
exercise. You will also need to quit smoking if you smoke. Taking your
medicines is also important.
Angioplasty has
some rare but serious risks. They are:
- The need for emergency open-chest surgery
during the procedure.
- Heart
attack.
- Stroke.
- Death.
Keep in mind that the chances of having a serious problem
with this procedure are higher if you are older than 70.
Less serious risks related to the catheter include:
- Pain, swelling, and tenderness at the catheter
insertion site.
- Bruising or bleeding at the catheter site.
Most
people recover from angioplasty fairly quickly. They usually go home after an
overnight stay in the hospital. They can return to normal activities within a
few days.
Medical
therapy includes making lifestyle changes and taking medicines. Lifestyle
changes play a big role in helping you live longer. They include eating a
healthy diet, not smoking, and getting daily exercise. Changing your habits may
not be easy, but it could keep your heart disease from getting worse. It could
even reverse some of the damage.
Your doctor will ask you
to:
- Stop smoking. Quitting smoking can greatly
lower your chance of having a heart attack and dying.
- Exercise almost every day. The American Heart Association
suggests that you exercise for at least 30 minutes on all or most days of the
week.
- Eat a
heart-healthy diet. This includes lots of fruits and
vegetables, whole grains, and lean protein. Try to eat fish at least 2 times a
week.
- Know your numbers. Keep track of your
blood pressure and
cholesterol, and take your medicines to keep your
numbers in a healthy range.
- Stay at a healthy
weight.
- Keep your blood sugar in a target range if you
have
diabetes.
Whatever choice you make about angioplasty, making these
lifestyle changes will give you the best chance of keeping heart disease from
getting worse. These changes are important for all people who have heart
disease.
Taking medicines every day is another key part of medical
therapy. You may need to take:
- Medicines to improve cholesterol, such as
statins.
- Beta-blockers to keep your heart from working too hard.
The medicine slows the heart rate and lowers blood pressure. It can help
relieve chest pain and may prevent it.
- ACE inhibitors to lower blood pressure and the risk of heart
attack.
- Aspirin or other medicines to
reduce the risk of blood clots and heart attacks.
- Nitrates, such as nitroglycerin, to stop chest
pain.
All medicines have side effects. Your doctor may lower the
dose or give you another drug if side effects bother you.
- Statins: The most common side effects
include muscle aches, an upset stomach, gas, constipation, belly pain or
cramps, and feeling more tired than usual. In rare cases, statins can cause
liver problems or muscle pain and damage.
- Beta-blockers: Side effects include dizziness and
feeling more tired than usual.
- ACE inhibitors: Side effects include a dry cough, nausea, diarrhea, and
swelling of the face and hands.
- Aspirin and other medicines to reduce the risk of blood clots: They can cause an upset
stomach and bleeding.
- Nitrates: Normal,
temporary side effects of nitroglycerin include a warm or flushed feeling, a
headache, dizziness, or lightheadedness. You may also have a burning feeling
under your tongue when you put the pill there.
Even if you choose to have angioplasty, you may need to
take at least some of these medicines.
Medical therapy and angioplasty can both relieve angina symptoms. They also can
make it easier for you to exercise, which is a key part of keeping your heart
healthy.
With angioplasty,
you'll feel relief from your angina symptoms sooner. But over time, both treatments work
the same to ease symptoms and improve quality of life.1
Many people try medical therapy first. But it
doesn't always work. You may decide to have angioplasty if you still have symptoms and can't exercise even after you have taken medicines and made lifestyle
changes.
Angioplasty can ease angina symptoms, but it has not been
proved to help you live any longer than medical therapy does. Also, angioplasty
does not lower the risk of having a heart attack any more than medical therapy
does.2
Your
doctor may recommend angioplasty if:
- You have angina symptoms that keep you from
exercising and enjoying your life.
- Medical therapy hasn't stopped
your angina.

Personal stories
Are you interested in what others decided to do? Many people have faced this decision. These personal stories may help you decide.
My chest
pain bothers me once in a while. But it's not too bad. My doctor said my angina
is mild. We talked about it, and we decided that I could try taking medicines
and taking better care of myself. At my age, any procedure has extra risks, so
I want to try the other stuff first.
I love to
take hikes with my daughter and grandchildren. And I love to travel. But I
can't walk very far, because my chest hurts. Even though I have been taking my
medicines and trying to eat well and exercise, my pain is still there. My
doctor and I agreed that angioplasty is a good choice for me.
My doctor
said I have one artery that is partly blocked. She said I don't need
angioplasty right now. Taking medicines and having a healthy lifestyle can
prevent a heart attack or stroke. The first thing I have to do is quit smoking.
I smoke a few cigarettes a day, but even a few is too many. So I will join a
stop-smoking program and keep up with my diet and exercise.
I've had
angina for a while now. I usually take nitroglycerin for it. But lately I've
had more pain when I do chores around the house or play golf. My doctor said
angioplasty might be an option because I have a couple of narrowed arteries. So
I'm going to have it. I'll still have to watch what I eat, get some exercise,
and take my medicines.
