Understanding Angiography and Angioplasty: Procedures, Purpose, and Recovery

Angiography and angioplasty are common medical procedures used to diagnose and treat heart and blood vessel problems. Understanding how these procedures work, why they are performed, and what to expect can help ease concerns and prepare you for the process.

What is Angiography?

Angiography, also known as a coronary angiogram, is a diagnostic test that uses X-ray imaging to see the heart’s blood vessels. It helps doctors identify blockages or narrowing in the arteries that supply blood to the heart.

Why Angiography is Performed

• To investigate chest pain (angina)
• To check for coronary artery disease (CAD)
• To assess heart function before surgery
• To evaluate blood flow after a heart attack
• To plan treatment for heart conditions

The Procedure

1. Preparation: You may need to fast for a few hours before the procedure. Inform your doctor of any medications or allergies.
2. During the Test:
   • Performed in a specialised room called a catheterisation lab.
   • A thin, flexible tube (catheter) is inserted into an artery in your wrist or groin.
   • A contrast dye is injected through the catheter, and X-ray images are taken.
3. Duration: The test usually takes around 30 minutes to an hour.
4. Risks: Angiography is generally safe but may carry minor risks such as bleeding, infection, or an allergic reaction to the dye.

What is Angioplasty?

Angioplasty, also known as percutaneous coronary intervention (PCI), is a procedure to open narrowed or blocked heart arteries. It helps restore normal blood flow, reducing chest pain and preventing heart attacks.

Why Angioplasty is Performed

• To relieve symptoms of coronary artery disease (such as angina)
• To treat a heart attack by quickly restoring blood flow
• To reduce the risk of future heart problems

The Procedure

1. Preparation: Similar to angiography. You may undergo angioplasty immediately after an angiogram if a blockage is found.
2. During the Procedure:
   • The catheter is guided to the blocked artery.
   • A small balloon at the catheter’s tip is inflated to widen the artery.
   • Often, a stent (a small wire mesh tube) is placed to keep the artery open.
3. Duration: The procedure may take one to two hours.
4. Risks: Potential risks include bleeding, artery damage, blood clots, or, rarely, heart attack or stroke.

Recovery and Aftercare

After Angiography

• You will be monitored for a few hours.
• Most people can go home the same day but should avoid strenuous activities for a day or two.
• Drink plenty of fluids to help flush the dye from your body.

After Angioplasty

• You may stay in hospital overnight for observation.
• Avoid heavy lifting or strenuous exercise for several days.
• Take prescribed medications, including blood thinners if a stent was placed.

When to Seek Medical Help

• If you experience chest pain, fainting, shortness of breath, or bleeding at the catheter site, seek urgent medical attention.

Benefits and Risks

Benefits:

• Improved blood flow to the heart
• Relief from chest pain
• Reduced risk of heart attack
• Quick recovery time compared to open-heart surgery

Risks:

• Complications from the catheter site
• Re-narrowing of the artery (restenosis)
• Rarely, serious complications such as heart attack or stroke

Final Thoughts

Angiography and angioplasty are essential procedures for diagnosing and treating heart conditions. They are generally safe and can significantly improve quality of life and heart health. If your doctor recommends these procedures, understanding what to expect can help you feel more confident and prepared.
