What is angiography test for heart?
Angiography is a type of X-ray used to check blood vessels. Blood vessels do not show clearly on a normal X-ray, so a special dye needs to be injected into your blood first. This highlights your blood vessels, allowing your doctor to see any problems. The X-ray images created during angiography are called angiograms.
Is angiography test painful?
A slight burning or “flushing” sensation can be felt after the dye is injected. After the test, pressure will be applied at the site where the catheter is removed to prevent bleeding. If the catheter is placed in your groin, you may be asked to lie flat on your back for a few hours after the test to prevent bleeding.
How is a heart angiogram test done?
To complete a coronary angiogram, a catheter is inserted in an artery in your groin or arm and threaded through your blood vessels to your heart. Your doctor uses the angiogram to check for blocked or narrowed blood vessels in your heart.
How long does angiography test take?
Angiography is done in a hospital X-ray or radiology department. It usually takes between 30 minutes and 2 hours, and you can usually go home the same day.

Why angiography is needed?
Why do we do an angiogram? When blood vessels are blocked, damaged or abnormal in any way, chest pain, heart attack, stroke, or other problems may occur. Angiography helps your physician determine the source of the problem and the extent of damage to the blood vessel segments that are being examined.
How much heart blockage is normal?
A moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually, heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms.
Can angiogram clear blockage?
Long-term outlook after a coronary angiogram Narrowed coronary arteries may possibly be treated during the angiogram by a technique known as angioplasty. A special catheter is threaded through the blood vessels and into the coronary arteries to remove the blockage.
How safe is angiography?
What are side effects of angiogram?
Risks associated with cardiac catheterization and angiograms include:
- allergic reactions to the local anesthetic, contrast dye, or sedative.
- bleeding, bruising, or soreness at the insertion site.
- blood clots.
- injury to an artery or vein.
- damage to the walls of the heart.
- acute kidney failure.
- infection.
- irregular heartbeat.

What are the side effects of an angiogram test?
Low blood pressure (hypotension)
What to expect after angiogram?

How serious is an angiogram?
The risks of angiograms include damage to the blood vessels, allergic reactions to tracer dyes, and bleeding at the site of injections and catheter insertions. Angiograms are invasive, and while the risks are low, they cannot be completely eliminated. Some patients may be more vulnerable to complications like kidney damage after an angiogram.
