What To Expect After Coronary Angiography
After coronary angiography, you'll be moved to a special care area, where you'll rest and be checked for several hours or overnight. During this time, you'll need to limit your movement to avoid bleeding from the site where the catheter was inserted.
While you recover in the special care area, nurses will check your heart rate and blood pressure regularly and see whether you're bleeding from the tube insertion site.
A small bruise may develop on your arm, groin (upper thigh), or neck at the site where the catheter was inserted. That area may feel sore or tender for about a week. Let your doctor know if you develop problems such as:
- • A constant or large amount of blood at the catheter insertion site that can't be stopped with a small bandage
- • Unusual pain, swelling, redness, or other signs of infection at or near the catheter insertion site
Talk to your doctor about whether you should avoid certain activities, such as heavy lifting, for a short time after the test.

What Are the Risks of Coronary Angiography?
Coronary angiography is a common medical test that rarely causes serious problems. But complications can include:
- • Bleeding, infection, and pain at the site where the catheter was inserted.
- • Damage to blood vessels. This is a very rare complication. It may occur if the catheter scrapes or pokes a hole in a blood vessel as it's threaded up to the heart.
- • An allergic reaction to the dye used.
Other less common complications of the test include:
- • An arrhythmia (irregular heartbeat) that often goes away on its own, but may need treatment if it persists.
- • Damage to the kidneys caused by the dye used.
- • Blood clots that can trigger stroke, heart attack, or other serious problems.
- Low blood pressure.
- • A buildup of blood or fluid in the sac that surrounds the heart. This fluid can prevent the heart from beating properly.
As with any procedure involving the heart, complications can sometimes be fatal. However, this is rare with coronary angiography.
The risk of complications from coronary angiography is higher if you have diabetes or kidney disease, or if you're 75 years old or older. The risk of complications also is greater in women and in people having coronary angiography on an emergency basis.
