Coronary angiogram
Coronary Angiogram[edit | edit source]
A coronary angiogram is a diagnostic procedure that uses X-ray imaging to see the heart's blood vessels. It is part of a general group of procedures known as cardiac catheterization. This test is often done to see if there's a restriction in blood flow going to the heart.
Indications[edit | edit source]
Coronary angiograms are used to diagnose and evaluate several heart conditions, including:
Procedure[edit | edit source]
The procedure involves inserting a catheter into a blood vessel in the arm or groin and threading it to the heart. A special dye (contrast material) is injected through the catheter, and X-ray images are taken to see how the dye moves through the coronary arteries.
Preparation[edit | edit source]
Before the procedure, patients may be asked to:
- Avoid eating or drinking for several hours.
- Inform the doctor of any medications or allergies.
- Arrange for someone to drive them home after the procedure.
During the Procedure[edit | edit source]
- The patient is awake but sedated.
- A local anesthetic is applied to the insertion site.
- The catheter is guided to the coronary arteries.
- Contrast dye is injected, and X-ray images are taken.
After the Procedure[edit | edit source]
- The catheter is removed, and pressure is applied to the insertion site to prevent bleeding.
- Patients are monitored for a few hours before being discharged.
- Instructions are given for care at home, including avoiding strenuous activities for a short period.
Risks[edit | edit source]
While generally safe, coronary angiograms carry some risks, including:
- Bleeding or bruising at the catheter insertion site
- Allergic reaction to the contrast dye
- Arrhythmia
- Heart attack
- Stroke
