What is a coronary angiography?
An angiography is a test in which X-ray images of the coronary arteries and veins supplying blood to the heart are taken. During an angiography, a catheter (special tube) placed into a blood artery releases a specific dye into the coronary arteries. When an X-ray is taken, this dye makes the blood vessels visible. Doctors can view how blood flows into the heart through angiography. This enables them to identify issues with the coronary arteries.
Dr. Leandro Perez shares an overview of the coronary angiogram and how it is performed.
Why is it done?
Angiography may be advised for individuals with angina (chest pain) or suspected coronary artery disease (CAD). The test provides doctors with crucial information on the state of the coronary arteries, including atherosclerosis, regurgitation (blood flowing backwards through the heart valves), and blood pooling in a chamber due to a valve malfunction.
How to prepare for a coronary angiography?
Coronary angiograms are sometimes conducted on an emergency basis. They are more typically arranged in advance, allowing you time to prepare.
Angiograms are conducted at our center. Our team will give you precise instructions and discuss any drugs you are taking with you. The following are some general guidelines:
Before your angiography, avoid eating or drinking after midnight.
Bring all of your prescriptions in their original bottles to the hospital. Consult your doctor about whether or not you should take your morning meds.
Ask your doctor whether you should take insulin or other oral drugs before your angiography if you have diabetes.
What can you expect during the test?
During the test, you will most likely be awake. You could feel some pressure where the catheter is inserted.
After the dye is administered, you may experience flushing or a warm sensation.
The catheter is withdrawn when the test is completed. To avoid bleeding, a strong pressure may be administered to the insertion site. You will be urged to lie flat on your back for a few hours to several hours following the test if the catheter was placed in your groin. It's possible that this will cause some back pain.
Angiography is a very common procedure that is considered to be risk-free. The contrast dye may produce nausea, the desire to pee, or even allergic responses in some people, though these adverse effects are uncommon.
After the procedure
Drink plenty of water and relax. Don't smoke or consume alcoholic beverages. You should not drive, operate machinery, or make any significant decisions after receiving an anesthesia.
After 24 hours, remove the bandage. Apply a new bandage for additional 12 hours if there is mild leakage. Don't have sex or undertake any strenuous exercise for two days. For at least three days, refrain from bathing, using a hot tub, or swimming in a pool. For three days, don't apply lotion around the puncture site.
A week following the test, you'll need to see your heart doctor.
