What is the indication for a myocardial perfusion scan?

What is the indication for a myocardial perfusion scan?

The major indications for MPS are diagnosis of coronary artery disease (CAD), risk stratification in patients with known CAD, assessment of therapy and intervention and myocardial viability before percutaneous intervention or bypass surgery.

What is abnormal myocardial 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.

How long does a MPI take?

We with inject a radiopharmaceutical into an arm vein. This material will be taken up by your heart muscle. Images of your heart will be taken 45 minutes later. These images take approximately 15 minutes to complete.

What is normal myocardial perfusion?

Abstract. Background: Normal or near normal myocardial perfusion stress imaging (MPI) suggests the absence of life-threatening coronary artery disease (CAD). Nevertheless, there are instances where severe left main or three-vessel CAD may be present despite no significant perfusion abnormalities on MPI.

How safe is a myocardial perfusion scan?

What are the risks of a stress myocardial perfusion scan? Risks of the scan may include: The exercise part of the test may lead to rare instances of abnormal heart rhythms, chest pain, or heart attack due to the stress on the heart caused by the exercise. The needle used to put in the IV may cause some pain.

Is myocardial perfusion scan safe?

Cardiac perfusion scans are usually safe. Anytime you’re exposed to radiation, there’s a small chance of damage to cells or tissue. That’s the case even with the low-level radioactive tracer used for this test. But the chance of damage is very low compared with the benefits of the test.

What is stress test with 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. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle.

What are the side effects of myocardial perfusion scan?

What are the risks of a stress myocardial perfusion scan?

• The exercise part of the test may lead to rare instances of abnormal heart rhythms, chest pain, or heart attack due to the stress on the heart caused by the exercise.
• The needle used to put in the IV may cause some pain.

When would I get a myocardial perfusion scan?

You might be recommended a Myocardial Perfusion Scan by your doctor if you are experiencing: After a heart attack to ascertain the level of myocardial infarction. After surgeries such as coronary bypass surgery, angioplasty, stent placement.

What are the side effects of myocardial perfusion?

Side Effects of Myocardial Perfusion Techniques. Pain, especially in your arm, back, jaw, neck, or ears If you need medication to stimulate blood flow for stress testing, you may temporarily feel: Shortness of breath and/or chest discomfort, which is a harmless side effect of the medicine.

What medications should I avoid taking before a pharmacologic myocardial perfusion scan?

If you are scheduled for a pharmacologic myocardial perfusion scan, you will need to avoid taking any medications containing theophylline or caffeine. Coffee, even decaffeinated, is not allowed, as it contains some caffeine. Medications for asthma may contain theophylline.

What type of radionuclide is used for a myocardial perfusion scan?

A radionuclide that concentrates in heart muscle is used for a myocardial perfusion scan. Other scans that use different radionuclides include a bone scan and a thyroid scan. See separate leaflets called Bone Scan and Thyroid Scans and Uptake Tests for more details. The radionuclide travels through the bloodstream and into the heart muscle.
