A Thallium Heart Scan, also known as a Diagnostic Angiography, is a diagnostic assay used to diagnose the blood flow to the heart muscle. The test helps healthcare providers assess other medical issues, assess 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 findings interpretation.

Preparation

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

• Refain From eating for at least 4 hours before the test
  
• Stay plenty of water to stay refueled
  
• Wear comfortable clothes
  
• Take Off any metallic objects, such as accessories, as they may intermix with the scan
  
• Inform the healthcare provider about any prescriptions or supplements they are taking
  
  

Test Procedure

The Nuclear Heart Scan involves two main components. The test starts with the patient lying flat on a table, and a small dose of radioactive tracer is injected into the bloodstream through an IV line. This tracer collects 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 listen a book, enjoy music, or view TV.

After the rest phase, the patient is asked to engage in exercise using a treadmill to increase the heart rate and اسکن هسته ای قلب cardiac output. This stress phase typically lasts for 5-10 minutes. The patient's blood pressure, heart rate, and electrocardiogram are supervised 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 removed from the bloodstream, and the patient is released to return home. The test outcomes are usually available within 24 hours, and patients can follow up with their healthcare provider to evaluate the findings.

Interpreting the Results

A Nuclear Heart Scan yields a set of images illustrating the heart's blood flow, which are then evaluated with the images obtained after exercise. The test findings indicate whether the heart muscle receives 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 outcomes indicate poor distribution of blood, which could be signs of coronary artery disease or other heart issues.
  
  

A Nuclear Heart Scan is a effective diagnostic test for monitoring heart health. While the results may seem complex, patients can trust that a qualified healthcare provider will explain the data to provide a concise understanding of their condition and offer the best course of treatment or care.
