A coronary angiogram is a test to examine the large blood vessel of your heart (coronary artery). The doctor inserted a thin, flexible tube (catheter) into a blood vessel in your groin. In some cases, the catheter is placed in a blood vessel in the arm.
Your groin or arm may have a bruise and feel sore for a day or two after a coronary angiogram. You can do light activities around the house but nothing strenuous for several days.
- If the doctor gave you a sedative:
- For 24 hours, don’t do anything that requires attention to detail. 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 a day or two. 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 arm near 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.
- If your doctor recommends it, get more exercise. Walking is a good choice. Bit by bit, increase the amount you walk every day. Try for at least 2½ hours a week.
- 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.
- Your doctor will tell you if and when you can restart your medicines. He or she will also give you instructions about taking any new medicines.
- If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, be sure to talk to your doctor. He or she will tell you if and when to start taking those medicines again. Make sure that you understand exactly what your doctor wants you to do.
- 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 or nurse call line 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.
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 or nurse call line 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.
