What is a Myocardial perfusion rest stress test?

What is a Myocardial perfusion rest stress test?

Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, your doctor may order this test to find areas of damaged heart muscle.

How long does a resting myocardial perfusion scan take?

Procedure completion, both methods: You will lie flat on a table while the images of your heart are taken. About 10 to 60 minutes (depending on the type of tracer used) after the tracer is injected, the gamma camera will begin to take pictures of your heart.

What is the resting part of a nuclear stress test?

For the resting portion of a cardiac stress test procedure, you receive an injection of thallium, a radioactive tracer. The tracer will circulate for 5-10 minutes and then pictures will be taken of your heart. This nuclear stress test imaging session takes 15 to 30 minutes to complete.

What is a normal summed rest score?

Summed stress scores of less than 3 are considered normal, whereas scores of 4–7, 8–12, and 13 or higher are indicative of low, intermediate, and high risk for a hard cardiac event.

How long are you radioactive after a nuclear stress test?

The radioactive liquid will be in your body for 24 to 36 hours after your test. You will need to do the following: Drink plenty of liquids as directed. This will help flush the radioactive liquid out of your body.

What is abnormal perfusion?

Abnormal results may mean your heart isn’t pumping as well as it should. This might happen when you have heart damage or heart disease. Myocardial perfusion scans help us diagnose: Coronary artery disease. Heart failure.

Can I drink coffee after nuclear stress test?

Caffeine can inhibit the medication needed for the stress portion of the test to be effective. If you’ve consumed caffeine within 24 hours, we may have to reschedule your test.

What is normal cardiac perfusion?

Global pixel-wise stress and rest perfusion were 2.3±1.4 ml/min/g and 0.9±0.3 ml/min/g, respectively. The average pixel-wise myocardial perfusion reserve (MPR) was 2.5±0.7.

What is a myocardial perfusion SPECT study?

A myocardial perfusion SPECT (Single Photon Emission Computed Tomography) study, also called a cardiac stress-rest test, helps your doctor evaluate your heart’s blood supply. Two sets of images showing blood flow are obtained: the first following a period of rest, and the second following a period of stress (i.e., exercise).

What is myocardial perfusion?

Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle.

What is a stress myocardial perfusion scan?

A stress myocardial perfusion scan assesses blood flow to the heart muscle when it is stressed. The heart is usually “stressed” from exercise. But, if you are unable to exercise, the heart can be stressed by taking a certain medicine that increases your heart rate or dilate blood vessels as would occur during exercise.

What is a cardiac perfusion assessment?

An evaluation of the blood flow ( perfusion) to the walls of your heart. Usually performed using a cardiac stress test. You have been scheduled for a diagnostic exam to evaluate the blood supply to your heart.
