Let's simply learn about the angiogram test, which looks for blockages in blood vessels?

An angiogram is a special X-ray test that is done to see if there is any blockage or narrowing in the blood vessels (arteries or veins) in your body. This allows doctors to see exactly where the blood is flowing in your body and if there is a problem. For example, it is used to find out exactly where there is a problem in the arteries or veins in places like the heart, neck, kidneys, or legs.

Why is an angiogram done? When is it needed?

Now you may be wondering, 'Why do I need an angiogram?' Your doctor will only recommend this test if there is any indication that your blood vessels are blocked, damaged, or have some other abnormality. This will help them determine exactly what the problem is and how much it has affected them . This will make it easier to plan treatment.

Simply put, an angiogram helps diagnose and plan treatment for conditions such as:

• Coronary artery disease: This is a blockage or narrowing of the arteries that supply blood to the heart.
• Peripheral artery disease: Blockage or narrowing of the arteries in the legs.
• Blood clots: Blood cells clump together and form a clot.
• Aneurysm: A weakening of an artery wall that bulges like a balloon.

How does this work?

Okay, let's see how this works. During an angiogram, a special substance (called a contrast material or dye) is injected into your body. This dye is visible on an X-ray machine. Then, when you look at the X-ray screen, you can clearly see how the blood is moving through your blood vessels, and if there is a blockage somewhere.

You will be given medication to help you relax and feel comfortable during this test. Most people will be given some level of sedation. Some people will be given general anesthesia, which means you will be completely asleep. However, you will need someone to drive you home after the test.

How do you prepare for an angiogram?

Before this test, some of your blood may be taken to see how your blood clots and whether your kidneys are working properly.

Be aware of medication

If you are taking any medications, especially blood thinners (antiplatelets, anticoagulants) , you should definitely talk to your doctor before stopping them. With your doctor's approval:

• Medications like ``Clopidogrel`` may be asked to be stopped five days before the test.
• You may be asked to stop taking blood-thinning medications such as `Dipyridamole` or `Warfarin` 72 hours before the test and for 24 hours after the test.
• Other common medications can be taken as usual.
• To youIf you have diabetes , ask your doctor exactly how and when you should take your insulin or other diabetes medications.

About food and drink

Do not eat or drink anything after midnight the night before the angiogram. If you will be given general anesthesia during the test, do not eat or drink anything after midnight the night before.

Remember these things on the day of the test

• Drink only light liquids (e.g. water, unsweetened tea) on the morning of the test.
• Leave your jewelry and valuables at home .
• Arrange for someone responsible to take you home.
• Bring a list of medications you are currently taking and details of any allergies you may have .
• If your doctor has to see an emergency patient, you may have to wait until your turn. So it's a good idea to bring something like a book or magazine.
• If you have diabetes, inform all medical staff members about it.
• You will have to wear a hospital gown and lie down on a special X-ray table.
• Before the test, talk to your doctor about your instructions, any questions you have, and your medical history.

What happens during the test?

When performing an angiogram, the doctor will:

• First, the area where the catheter will be inserted is numbed.
• Then, a needle is used to insert into one of your blood vessels.
• A wire is passed through that needle.
• A long, thin tube called a catheter is inserted over the wire into a large artery, usually in your groin or wrist.
• Then, very carefully, the catheter is guided along the artery until it reaches the part of the blood vessel that needs to be examined.
• Now, a little of the previously mentioned `contrast material` (i.e. `dye`) will be injected into your blood vessel through the catheter. At this time , you may feel a warm sensation for a few seconds, or you may feel like you need to urinate . This is normal, don't worry.
• Then an X-ray is taken.
• By looking at the X-ray monitor, watching the dye move, you can see exactly how the blood is moving through your blood vessels and where there are blockages.

How long does an angiogram take?

An angiogram can usually be completed in as little as 15 minutes , but it can sometimes take several hours. This depends on whether the doctor will perform any additional treatment after the problem is identified.

Imagine, if the doctor finds a blockage, he will immediately perform angioplasty.This treatment involves using a small balloon-like device to push the blocked area against the artery wall. If this allows for good blood flow and less than 30% of the blockage is left, angioplasty may be the only option.

But if the angioplasty doesn't create a large enough opening for blood to flow, you may need to have a stent inserted. This is a small metal mesh-like tube that is placed inside the blood vessel and helps keep it open. This can be inserted right after the angioplasty.

Another treatment option is coronary artery bypass surgery or peripheral artery bypass surgery . This involves creating a new path for blood to flow around the blocked artery. However, this surgery is performed on a separate day.

What happens after the test?

Your doctor will remove the catheter and place a bandage over the puncture site in your skin. The bandage will be held in place for at least 15 minutes to stop or prevent bleeding.

If the catheter was inserted through your leg, you will need to rest in bed for four to six hours. This will help reduce bleeding from the wound.

Before going home

Before sending you home, the doctor will examine you and talk to you about instructions to follow at home.

When you go home (while recovering from the angiogram)

Even if you have had angioplasty and stent placement, you will be able to go home the same day or the next day after the angiogram. However, since you were given anesthesia, you will need someone to take you home .

After you go home, do not lift more than 10 pounds (about 4.5 kg) for the next two days, do not bend over, or stoop . This will help prevent bleeding from the wound.

It's a good idea to have a responsible adult stay with you the night of the test. Some people may need to stay in the hospital overnight to recover.

If you have diabetes, do not take metformin for 48 hours after the test . This reduces the risk of kidney complications.

Drink plenty of water . This will help the dye leave your body quickly.

What are the risks of an angiogram?

The risks of an angiogram are very low. However, there may be minor complications where the doctor makes a puncture in your skin to access your artery. These complications occur in less than 1% of cases .

The risks of an angiogram are usually related to the site of the puncture. They include:

• Bruises: These are normal and will go away within a week to three weeks.
• Bleeding
• Infection
• Pain
• Kidney problems
• Allergic reaction to contrast material (dye)
• Damage to blood vessels
• An abnormal heartbeat (arrhythmia) or a condition such as cardiac arrest (cardiac arrest) requiring resuscitation.
• A blood clot blocks a blood vessel, causing a heart attack or stroke (very rare)
• Bleeding from a blood vessel (very rare)

How are the results obtained? What do they tell us?

The doctor may find minor problems that are not serious. They may not need any major treatment. They may tell you to take medication or make some changes in your daily life. For example, exercise more or eat healthier.

But sometimes there are larger blockages. That requires a little more treatment. If that's the case, the doctor can do an angioplasty at the same time as the angiogram, placing a stent to open up your artery and keep it open.

Some people need separate treatment on a separate day. The doctor may recommend a bypass operation, which creates a path for blood to flow around the blockage.

When will the results be known?

Your doctor will likely talk to you after your angiogram is done. However, your doctor may need some time to review your X-ray images before deciding what to do next.

When should you see the doctor again?

If any of these things happen, see your doctor immediately:

• If you have pain or discomfort that does not subside despite taking medication .
• If it is difficult to talk or smile .
• If you have numbness, weakness, warmth, or swelling in the arm or leg where the catheter is inserted.
• If you get a fever .
• If there is a lump near the wound .
• If there is bleeding from the site where the catheter was inserted into the skin.

Is an angiogram a major surgery?

No. An angiogram is a ``minimally invasive`` test that is done without making a large incision . It is not surgery. The doctor works through a very small hole. That hole is just big enough to put a catheter into your blood vessel.

How serious is an angiogram?

An angiogram is a low-risk test. However, it is very important to follow your doctor's instructions on how to prepare for it.

Is this painful?

The angiogram is not very painful .

You won't feel any major pain. You might just have some minor discomfort. So don't be afraid!

The doctor will inject a local anesthetic to numb the area where the catheter is inserted, and you will feel the needle hit your skin. After that, you will probably not feel any pain during the test. You may feel a slight pinch when the catheter is inserted. After the test, you may have some soreness or bruising where the catheter was inserted.

Are angiogram and angioplasty the same thing?

No. An angiogram can help your doctor see if there is a blockage in one of your arteries. During the angiogram, your doctor can perform an angioplasty to treat the blockage.

Who is doing this test?

An angiogram of the heart is done by an interventional cardiologist . Angiograms of arteries in other parts of the body (e.g., the legs) are done by interventional radiologists and vascular surgeons . Angiograms of the brain are done by interventional neurologists . The doctor who does the angiogram can study your images and identify areas of concern.

Finally, finally, remember this.

If your doctor tells you to have an angiogram, it means they are looking for answers to some questions. The information from the angiogram will help them decide whether you need treatment. If appropriate for your condition, they may even treat your condition while you are having the test.

However, this is done in a way that makes you feel comfortable and relaxed. There is no reason to be afraid.

If you have any questions about the angiogram or what it might find, don't be afraid to ask your doctor. Remember, this is done to help you improve your health.
