Coronary Artery Disease: Should I Have an Angiogram? Get the facts
Your options Have an angiogram to help decide how best to treat your coronary artery disease. Don't have an angiogram. This decision aid is for people who have coronary artery disease and stable angina. This means that your angina symptoms, such as chest pain or pressure, happen at times you can predict. They happen when your heart is working hard, such as during exercise. Your symptoms go away when you rest or after you take nitroglycerin.
Key points to remember An angiogram can show if your coronary arteries are narrowed, where they are narrowed, and by how much. It can help your doctor see if a change in treatment—such as medicines, angioplasty coronary artery bypass surgery An angiogram can't show if narrowed places in your arteries will cause a heart attack. Other tests may give you and your doctor all the information you need to make treatment decisions. These other tests do not have the risks of an angiogram. If, during the test, your doctor sees that your arteries are narrowed, angioplasty could be done right away. So before you have the test, it's a good idea to talk with your doctor about this possible treatment. Ask what the test might show and what your choices are in each case. You may not want an angiogram if you already know that you don't want to have angioplasty or bypass surgery. Compare your options

Have an angiogram Have an angiogram An angiogram takes about 1 to 3 hours. You will get a shot to numb the site where a catheter is placed in your blood vessel. After the test, you will stay in a recovery room for a few hours. You may go home the same day or the next day. You have a heart-healthy lifestyle. This includes quitting smoking, eating a heart-healthy diet, staying at a healthy weight, and getting regular exercise. You take medicines to lower your risk of a heart attack. You also may take medicines to help control angina. The test helps you and your doctor decide what treatment will improve your symptoms and lower your risk for a heart attack. Treatments include medicines and a heart-healthy lifestyle and maybe a procedure or surgery (along with medicines and a healthy lifestyle). An angiogram has some risks. They include: Allergic reaction to the dye used to see the coronary arteries. Bleeding at the site where the catheter is placed. Kidney damage related to the dye. Heart attack. Stroke. Death. Don't have an angiogram Don't have an angiogram You have a heart-healthy lifestyle. This includes quitting smoking, eating a heart-healthy diet, staying at a healthy weight, and getting regular exercise. You may take medicines to lower your chance of a heart attack. These include aspirin and medicines to control your cholesterol and blood pressure. You may take medicines to help control angina. You may have other tests that give you and your doctor the information you need. You avoid the risks of an angiogram. You may avoid treatments (angioplasty or surgery) that you don't want. You can decide later to have an angiogram. Medicines and a healthy lifestyle may not improve your angina as much as you would like. I've been taking medicines for my angina, but my symptoms are still bothering me on my walks every day. My doctor said that an angiogram could show if an angioplasty could help me feel better. But she also said I could try a different angina medicine first and see if that helped. So I'm going to do that. I can still have the test later.
I was getting chest pain after I walked a few blocks, or even less if it was cold out. I thought it was just my lungs, but when I saw my doctor, he said he thought it was my heart. So I took a treadmill test. Based on my results, my doctor thought I probably had some narrowing in my heart arteries. But he said it didn't seem too bad. We decided to try some medicine to see if that helps instead of having that test where they put dye in your arteries. I have been doing well and almost never get chest pain anymore.
My heart medicine just isn't working as well as it used to. Although my angina is stable, I am not feeling as well as I'd like to. I want to have the energy to play with my grandkids and the confidence to take the holidays my wife and I always planned. I've decided to have an angiogram so that my wife, my doctor, and I can make a decision about whether there may be something else that can help me.
My chest pain is getting so bad that I can't do my gardening. And that's my favourite thing to do. So when my doctor recommended an angiogram, I was all for it. I decided I would rather have the test and then decide whether I want to get a stent.

What is a coronary angiogram? A coronary angiogram is an X-ray test that takes pictures of the blood flow through your coronary arteries
During the test, a thin tube called a catheter is placed in an artery of your wrist or groin. It's then gently threaded up into your heart. A dye is put through the catheter. The dye helps your doctor see the arteries on the X-ray.
Before the test, you may get medicine that relaxes you or puts you in a light sleep. The area being worked on will be numb. You may feel a brief sting or pinch from the numbing medicine. You may feel some pressure when the doctor puts in the catheter. You will probably feel some warmth when the dye is put in.
The procedure will take about 1 to 3 hours. You may be able to go home later the same day. Some people need to stay in the hospital overnight. You will need to avoid strenuous activity until your doctor says it is okay. This may be for several days.
What is coronary artery disease? Coronary artery disease occurs when fatty deposits called plaque (say "plak") build up inside the coronary arteries. These arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it can narrow the arteries. This may limit how much blood can get to your heart muscle. If the plaque breaks apart, a blood clot could cause a heart attack.
Narrowing of the arteries can lead to symptoms of angina
Treatment of coronary artery disease helps relieve symptoms. It also can slow how quickly the disease gets worse and can prevent a heart attack. Treatments include medicines, a heart-healthy lifestyle, angioplasty
Why is an angiogram done? An angiogram can help you and your doctor decide what treatment is best for you.
You may decide to have an angiogram because:2
It can help your doctor see if a change in treatment might lower your risk of heart attack or death from heart problems. An angiogram can show your doctor where plaques have narrowed your arteries and if blood flow is slowed. But it can't show if these plaques will cause a heart attack. You want more relief from your angina. The test can show your doctor if a procedure or surgery could improve your symptoms. It's important to talk with your doctor about your angina symptoms. Do your symptoms limit your daily activities and make it hard to enjoy your life? Do you have angina during light physical activity, such as walking a couple of blocks or up stairs? Also, if you are taking medicine for angina, let your doctor know if it doesn't control your symptoms enough. Your doctor may change your dose or suggest a different medicine.
Having the test doesn't mean that you will have an angioplasty or bypass surgery.
But, if during the angiogram the doctor sees that your arteries are narrowed, angioplasty could be done right away. So before you have an angiogram, talk with your doctor about a possible angioplasty. During the test, you may not be able to decide about more treatment, because you might be sleepy from medicines.
Why might you choose not to have an angiogram? An angiogram isn't right for everyone.2
Other tests may give you and your doctor all the information you need to make treatment decisions. These other tests do not have the risks of an angiogram. It's usually not suggested if you have a low risk of a heart attack or you don't have angina symptoms. If you can control your angina with medicines and a heart-healthy lifestyle, this test likely will not lead to changes in your treatment. You might choose not to have the test if you already know that you don't want to have angioplasty or bypass surgery. What are the risks of an angiogram? Most people do not have problems during or after an angiogram.
Heart attack and stroke happen rarely, but they can be life-threatening. They are more likely to occur in older people or people who have health conditions that raise the risk of heart attack or stroke.
Other problems that can happen during or soon after an angiogram include:
A tear or sudden closure in an artery. An allergic reaction to the dye used to see the arteries. Kidney damage related to the dye. Bleeding or bruising where the catheter was put in. Conditions that can raise risk of problems Certain health conditions can raise your risk of having problems after angioplasty. Conditions that can raise the risk of death from the procedure include heart failure, heart valve problems, and chronic kidney disease. The risk of heart attack may be higher if you have heart disease in the left main coronary artery.
Having these conditions doesn't mean that you will have a problem from the procedure. You and your doctor can talk about whether your risk of a problem is higher than average.
Radiation risk There is always a slight risk of damage to cells or tissues from being exposed to any radiation. This includes the low levels of X-ray used for this test.
Ask your doctor about your risk of radiation from this test. Talk about whether you feel the benefits of the test might outweigh the risks.
What do numbers tell us about benefits and risks of an angiogram? Benefits The benefits of an angiogram aren't the kinds of things that can be directly measured by numbers. The main reason to think about having the test is that it can help you and your doctor make better decisions about whether and how to treat your heart disease.
Risks Fewer than 1 out of 100 people have a stroke, bleed heavily, or die soon after a coronary angiogram.1
