What to ask Your Doctor before Coronary Angiogram?

Coronary angiogram is a complex yet arty procedure where the cardiologist dexterously inserts a narrow tube called catheter through the femoral/ radial artery with plastic introducer sheath. The catheter is guided through the artery into the heart and then dye is injected into the artery. The dye flows through the artery to the heart and stops or goes slow at the clogs in the heart arteries. The percentage of block is asserted by the cardiologists. This whole process is monitored through a highly defined x-ray machine managed by specialized technicians. As much as it sounds easy, coronary angiogram has immense risks attached if not performed by specialized team.

How important or necessary is this test for diagnosis?

Angiography is an important procedure that confirms the ailment. It's just an invasive diagnostic that help the doctors decide on the treatment thereafter.

Are allergic to iodine dye used in the test

Have ever had a serious allergic reaction

Have asthma

Are allergic to any medicines

Have any bleeding problems or are taking blood-thinning medicines

Have a history of kidney problems or chronic diabetes

What will happen during the procedure?

During a coronary angiogram, a type of dye that's visible by X-ray machine is injected into the blood vessels of your heart. The x-ray machine rapidly takes a series of images (angiograms), giving a detailed look at the inside of your blood vessels and the heart.

What are the risks?

Most of the times, major complications are rare. However, potential risks and complications include: heart attack, stroke, injury to the catheterized artery, irregular heart rhythms, allergic reactions to the dye or medications used during the procedure, kidney damage, excessive bleeding, infection, blood clots, radiation exposure from the X-rays

What does it reveal?

An angiogram show doctors what's wrong with your blood vessels. It can:

Show how many of your coronary arteries are blocked or narrowed

Locate the blockages in your blood vessels

Show how much blood flow is blocked through your blood vessels

Check the results of previous coronary bypass surgery or stenting

Check the blood flow through your heart and blood vessels

Check the size and movement of the heart valves

Based on the results, your cardiologist decides on the treatment from which you would be optimally benefited. For instance, that you would benefit from having coronary angioplasty, bypass surgery, valve replacement or just medical management.
