Left heart catheterization is a procedure to look at your heart and its arteries. You may need this procedure if you have chest pain, heart disease, or your heart is not working as it should.

DISCHARGE INSTRUCTIONS:

Call your local emergency number (911 in the US) if:

• Your catheter site does not stop bleeding even after you apply firm pressure for 10 minutes.
• You have any of the following signs of a heart attack:
  • Squeezing, pressure, or pain in your chest
  • You may also have any of the following:
    • Discomfort or pain in your back, neck, jaw, stomach, or arm
    • Shortness of breath
    • Nausea or vomiting
    • Lightheadedness or a sudden cold sweat
• You have any of the following signs of a stroke:
  • Numbness or drooping on one side of your face
  • Weakness in an arm or leg
  • Confusion or difficulty speaking
  • Dizziness, a severe headache, or vision loss
• You feel lightheaded, short of breath, or have chest pain.
• You cough up blood.

Seek care immediately if:

• The catheter site is swollen and filled with blood or is bleeding.
• The leg or arm used for your procedure is numb, painful, or changes color.
• The bruise at your catheter site gets bigger or becomes swollen.
• You are dizzy or have a severe headache or vision loss.
• Your arm or leg feels warm, tender, and painful. It may look swollen and red.

Call your cardiologist or doctor if:

• You have a fever.
• Your catheter site is red, leaks pus, or smells bad.
• You have increasing pain at your catheter site.
• You have questions or concerns about your condition or care.

Apply firm, steady pressure if bleeding continues:

A small amount of bleeding from the catheter site is possible. Apply pressure with a clean gauze or towel for 5 to 10 minutes. Call your local emergency number (911 in the US) if bleeding becomes heavy or does not stop.

Care for the catheter site:

Most bandages can be removed the day after your procedure. Gently clean the catheter site with soap and water. Do not rub the site. Do not take a bath, swim, or get in a hot tub until your healthcare provider says these are okay. If you need to cough, support the catheter site with your hand.

Activity:

Rest for 1 or 2 days after your procedure. Slowly start to do more each day. Take walks around your house. Make a plan for rest during the day. Your provider will tell you when you can drive, go back to work, or do other activities. The following activity limits are based on the catheter insertion site:

• Wrist: Follow these guidelines for 1 week, or as directed.
  • Do not lift anything heavier than 2 pounds.
  • Do not push or pull with the arm used for the procedure.
  • Avoid activities that use your arm or wrist, such as tennis, bowling, and golf.
• Groin: Follow these guidelines for as long as shown below, or as directed.
  • Do not have sex for 2 days.
  • Do not lift anything heavier than 5 pounds for 1 week.
  • Limit stair climbing for 1 week.
  • Avoid intense exercise for 2 to 4 weeks.

Drink liquids as directed:

Drink extra liquids if contrast liquid was used during your procedure. Liquid will help flush the contrast out of your body. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you. Do not drink alcohol for at least 24 hours after your procedure.

Go to cardiac rehabilitation (rehab), if directed:

Your cardiologist may recommend that you attend cardiac rehab. This is a program run by specialists who will help you safely strengthen your heart and reduce the risk for more heart disease. The plan includes exercise, relaxation, stress management, and heart-healthy nutrition. Healthcare providers will also check to make sure any medicines you are taking are working.

If you have a stent:

• Carry your stent card with you at all times.
• Let all healthcare providers know that you have a stent.
• If you need an MRI, wait at least 6 to 8 weeks after stent placement, or as directed.

Follow up with your cardiologist or doctor as directed:

Write down your questions so you remember to ask them during your visits.
