A Myocardial Heart Scan, also known as a Diagnostic Angiography, is a diagnostic test used to diagnose the blood flow to the heart muscle. The test helps healthcare providers assess heart conditions, evaluate the damage caused by a heart attack, and monitor the heart's function. In this guide, we will walk through the entire process of a Nuclear Heart Scan, from preparation to results analysis.

Preparation

Before undergoing a Nuclear Heart Scan, patients must follow a few preparation guidelines to ensure the test's validity. Patients are usually asked to:

• Avoid eating for at least 4 hours before the test
  
• Hydrate plenty of water to stay well-hydrated
  
• Wear loose-fitting clothes
  
• Remove any metallic objects, such as accessories, as they may interject with the scan
  
• Tell the healthcare provider about any prescriptions or supplements they are taking
  
  

Test Procedure

The Nuclear Heart Scan involves two main steps. The test starts with the patient lying flat on a table, اسکن هسته ای قلب and a small dose of radioactive substance is injected into the bloodstream through an IV line. This tracer concentrates in the heart muscle, allowing healthcare providers to visualize the heart's blood flow.

For the rest phase, the patient remains calm and still for 30 minutes to an hour, allowing the tracer to distribute evenly throughout the heart. During this time, the patient may read a book, listen to music, or watch TV.

After the rest phase, the patient is asked to exercise using a treadmill to increase the heart rate and cardiac output. This stress phase typically lasts for 5-10 minutes. The patient's blood pressure, heart rate, and electrocardiogram are monitored closely during exercise.

Following exercise, the patient returns to a resting state for an additional 30 minutes to an hour, allowing the heart to recover.

Post-Test

After the test, the tracer is eliminated from the bloodstream, and the patient is released to return home. The test findings are usually available within 24 hours, and patients can follow up with their healthcare provider to interpret the findings.

Interpreting the Results

A Nuclear Heart Scan yields a set of images showing the heart's blood flow, which are then evaluated with the images obtained after exercise. The test outcomes indicate whether the heart muscle obtains adequate blood flow during rest and exercise.

• A normal test shows homogeneous blood flow distribution throughout the heart muscle during both rest and exercise phases.
  
• Abnormal test results indicate areas of reduced of blood, which could be signs of coronary artery disease or other heart issues.
  
  

A Nuclear Heart Scan is a non-invasive diagnostic test for assessing heart health. While the findings may seem complex, patients can rest assured that a qualified healthcare provider will diagnose the data to provide a understandable understanding of their condition and recommend the best course of treatment or care.
