Coronary Angiogram: What to Expect at Home

Catheter insertion sites on arm and groin, showing catheter from groin to heart, and detail of catheter in coronary artery

Your Recovery

A coronary angiogram is a test to examine the large blood vessels of your heart (coronary arteries). The doctor inserted a thin, flexible tube (catheter) into a blood vessel in your groin or wrist.

Your groin or wrist may have a bruise and feel sore for a few days after the procedure. You can do light activities around the house. But do not do anything strenuous until your doctor says it is okay. This may be for several days.

This care sheet gives you a general idea about how long it will take for you to recover. But each person recovers at a different pace. Follow the steps below to feel better as quickly as possible.

How can you care for yourself at home?

Activity

 
  • If the doctor gave you a sedative:
    • For 24 hours, don't do anything that requires attention to detail, such as going to work, making important decisions, or signing any legal documents. It takes time for the medicine's effects to completely wear off.
    • For your safety, do not drive or operate any machinery that could be dangerous. Wait until the medicine wears off and you can think clearly and react easily.
  • Do not do strenuous exercise and do not lift, pull, or push anything heavy until your doctor says it is okay. This may be for several days. You can walk around the house and do light activity, such as cooking.
  • If the catheter was placed in your groin, try not to walk up stairs for the first couple of days.
  • If the catheter was placed in your wrist, do not bend your wrist deeply for the first couple of days. Be careful using your hand to get into and out of a chair or bed.
  • Get regular exercise. Walking may be a good choice. Try for at least 30 minutes on most days of the week.

Diet

 
  • Drink plenty of fluids to help your body flush out the dye. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
  • Keep eating a heart-healthy diet that has lots of fruits, vegetables, and whole grains. If you have not been eating this way, talk to your doctor. You also may want to talk to a dietitian. This expert can help you to learn about healthy foods and plan meals.

Medicines

 
  • Your doctor will tell you if and when you can restart your medicines. You will also be given instructions about taking any new medicines.
  • If you stopped taking aspirin or some other blood thinner, your doctor will tell you when to start taking it again.
  • Your doctor may prescribe a blood-thinning medicine like aspirin or clopidogrel (Plavix). It is very important that you take these medicines exactly as directed in order to keep the coronary artery open and reduce your risk of a heart attack. Be safe with medicines. Call your doctor if you think you are having a problem with your medicine.

Care of the catheter site

  • For 1 or 2 days, keep a bandage over the spot where the catheter was inserted. The bandage probably will fall off in this time.
  • Put ice or a cold pack on the area for 10 to 20 minutes at a time to help with soreness or swelling. Put a thin cloth between the ice and your skin.
  • You may shower 24 to 48 hours after the procedure, if your doctor okays it. Pat the incision dry.
  • Do not soak the catheter site until it is healed. Don't take a bath for 1 week, or until your doctor tells you it is okay.
  • Watch for bleeding from the site. A small amount of blood (up to the size of a quarter) on the bandage can be normal.
  • If you are bleeding, lie down and press on the area for 15 minutes to try to make it stop. If the bleeding does not stop, call your doctor or seek immediate medical care.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You passed out (lost consciousness).
  • You have severe trouble breathing.
  • You have sudden chest pain and shortness of breath, or you cough up blood.
  • You have symptoms of a heart attack. These may include:
    • Chest pain or pressure, or a strange feeling in the chest.
    • Sweating.
    • Shortness of breath.
    • Nausea or vomiting.
    • Pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly, or in one or both shoulders or arms.
    • Lightheadedness or sudden weakness.
    • A fast or irregular heartbeat.
  • After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
  • You have been diagnosed with angina, and you have symptoms that do not go away with rest or are not getting better within 5 minutes after you take a dose of nitroglycerin.

Call your doctor now or seek immediate medical care if:

  • You are bleeding from the area where the catheter was put in your artery.
  • You have a fast-growing, painful lump at the catheter site.
  • You have signs of infection, such as:
    • Increased pain, swelling, warmth, or redness.
    • Red streaks leading from the catheter site.
    • Pus draining from the catheter site.
    • A fever.
  • Your leg or hand is painful, looks blue, or feels cold, numb, or tingly.

Watch closely for changes in your health, and be sure to contact your doctor if you have any problems.
