Myocardial radionuclide examination

With the continuous development of modern society, there have been certain major breakthroughs in various fields. Medicine has developed rapidly, and medical treatment methods are becoming more and more updated, which has given people a certain psychological confidence. Some methods of human body examination are also deeply trusted by people. So what is myocardial radionuclide examination? Today I will give you a brief introduction on what myocardial radionuclide examination is.

Myocardial ischemia is a way doctors evaluate how well the heart is functioning. It uses imaging tests to show:

How much blood does the myocardium supply?

What happens when the heart pumps blood to the rest of the body

Usually myocardial radionuclide examination is done together with "stress test". A stress test measures how well the heart works when it beats faster, when it demands more blood. A stress test can check whether the heart is getting enough blood during this time. The stress test is done together with the myocardial isotope examination, which is called the "radionuclide exercise stress test".

2. Why do doctors need to perform myocardial radionuclide examination?

Doctors may do myocardial ischemia or radionuclide exercise stress testing in the following situations:

Check for insufficient blood flow to the heart muscle

Diagnosing heart disease or following up on patients with confirmed heart disease

Post-MI or post-cardiac surgery examinations

See how the heart pumps blood to the rest of the body

3. What preparations are needed before undergoing myocardial radionuclide examination?

Before the myocardial ischemia test, your doctor will ask you about all the medications you are taking, and they may adjust your medications. Avoid eating or drinking before the test, and avoid drinking anything with caffeine 24 hours before the test.

4. What will be done during myocardial radionuclide examination?

First, your doctor, nurse, or technician will do an electrocardiogram (ECG or EKG), which records your heart's electrical activity by recording your heart rate and rhythm.

Myocardial radionuclide examinations involve small amounts of radiation; excessive exposure may cause serious health problems, such as malignant tumors. For most people, the amount of radiation from a cardiac radionuclide scan alone does not cause any long-term problems. However, your doctor will tell you about the possible side effects of radiation before the examination.

Other possible disadvantages of myocardial radionuclide examination include:

Possible redness or pain at the site of the IV in your arm

Side effects of stress testing - the heart rate will increase significantly during exercise, and people may feel chest pain, difficulty breathing, palpitations or dizziness.
