After coronary angiography, you'll be moved to a special care area in the hospital. You’ll be carefully watched 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. They’ll also watch for any bleeding at the catheter insertion site.
You may develop a small bruise on your arm, groin (upper thigh), or neck at the catheter insertion site. 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
Your doctor will tell you whether you should avoid certain activities, such as heavy lifting, for a short time after the test.
