Nuclear Stress Test

Nuclear Stress Test at Palm Beach Cardiology Center

A nuclear stress test, also known as a myocardial perfusion imaging (MPI) test, is a diagnostic procedure used to evaluate the blood flow to the heart muscle under stress. During the test, a small amount of radioactive material is injected into a vein, which helps to visualize the blood flow to the heart using a special camera. The test involves two parts: one when the heart is at rest and another when the heart is stressed, typically through exercise on a treadmill or with medication that simulates the effects of exercise. This imaging helps doctors identify areas of reduced blood flow, assess the severity of coronary artery disease, and guide treatment decisions. The procedure is generally safe, with minimal risks, and can provide valuable information about your heart’s health and function.

Nuclear Stress Test Q & A

What is a nuclear stress test?

A nuclear stress test, also known as myocardial perfusion imaging (MPI), is a diagnostic procedure that assesses blood flow to the heart muscle under both rest and stress conditions. It involves injecting a small amount of radioactive material into the bloodstream and using a special camera to create images of the heart.

Why would I need a nuclear stress test?

A nuclear stress test is used to evaluate how well blood flows to the heart muscle, especially in individuals with symptoms such as chest pain, shortness of breath, or abnormal results from other heart tests. It helps diagnose coronary artery disease, determine the extent of heart damage, and guide treatment decisions.

Are there any risks associated with a nuclear stress test?

The nuclear stress test is generally safe, but potential risks include a small amount of radiation exposure, allergic reactions to the radioactive material, or side effects from the stress-inducing medication. Your healthcare provider will discuss these risks and benefits with you before the test.

How long does a nuclear stress test take?

The entire procedure usually takes about 2 to 3 hours. This includes preparation, the resting phase, the stress phase, and image acquisition.
