After having cardiac catheterisation and coronary angiography, your pulse and blood pressure will be checked and recorded.
If the catheter was inserted into your groin, a nurse may apply pressure for up to 10 minutes to stop the bleeding after the catheter and sheath have been removed.
Sometimes the doctor carrying out the procedure inserts a small surgical plug, a special stitch or another closure device to seal the wound. In these cases, it is not necessary to apply pressure to the wound.
If the catheter was inserted into your arm, a small pressurised cuff may be placed around your arm. The pressure is gradually decreased over the course of several hours.
A nurse will check whether there's any bleeding at the point where the catheter was inserted.
You should be able to sit up straight away and may be able to walk around soon afterwards if the catheter was inserted into your arm.
But if the catheter was inserted into your groin, you'll be asked to lie flat after any bleeding has stopped.
If all is well, you'll be asked to sit up after a few hours and should be able to get up and walk around shortly after.
You should tell the healthcare professionals treating you if you feel unwell at any time after the procedure.
Most people are able to go home on the same day the procedure is carried out, although you'll need to arrange a lift home from a family member or friend.
You should also make sure that someone stays with you overnight in case you experience any problems.
Most people feel fine a day or so after having the procedure. You may feel a bit tired, and the wound site is likely to be tender for up to a week.
Any bruising may last for up to 2 weeks.
You'll be advised about things to do or avoid during your recovery before leaving hospital.
Examples of advice you may be given include:
- Avoid having a bath for a day or so. You can still take a shower, but try to keep the wound as dry as possible.
- If you have a plaster on your groin, it can be removed the day after the procedure and it does not usually need to be replaced.
- Do not drive until told that it's safe to do so, which may not be for up to 3 days.
- Avoid playing sport, excessive activity or lifting anything heavy for about 2 days.
Contact the hospital unit where the procedure was carried out if you have concerns about your wound or recovery in general.
When to seek medical advice
Contact your GP if you experience:
- any increase in pain, swelling, redness or discharge at the wound site
- a high temperature
- a change in colour, coldness or numbness in the leg or arm on the same side of the body where the catheter was inserted
If you experience any bleeding from your wound, apply pressure to the area.
If the bleeding from your wound does not stop or restarts after applying pressure for 10 minutes, dial 999 and ask for an ambulance.
