A nuclear stress test is read by a cardiologist or a radiologist (imaging expert), who interprets the images and EKG data to check for blood flow problems or heart damage, then sends a detailed report to your referring doctor, who discusses the results with you and determines next steps for treatment or further testing.
Results of a nuclear stress test may take a few days. A heart expert (cardiologist) or radiologist (imaging expert) must review the images and interpret the results. Normal results at rest and under stress mean your blood flow is good.
Once your stress test is complete, a cardiologist will review the results and share them with you. Common test results may mean: If there is normal blood flow and heart function during rest and exercise, you may not need any further testing or treatment.
What are the next steps after a nuclear stress test? If your nuclear stress test is abnormal, which suggests a significant blockage in your coronary arteries, you will need further testing. “The next step is to visualize the coronary artery directly, either with a CT scan or a cardiac catheterization,” Dr. Kelly says.
A nuclear stress test helps identify blockages and areas of poor blood flow in the heart. Detecting a blockage during the test may indicate a risk for heart disease. Precautions are necessary after the test to ensure safety.
Nearly half of all Americans have one of the three major risk factors for coronary artery disease: smoking, high blood pressure and high cholesterol. High blood pressure is often called “the silent killer” because you may have it without experiencing any symptoms.
Cardiac catheterization and angiogram.
This test can see blockages in the heart arteries. A doctor places a long, thin flexible tube called a catheter in a blood vessel, usually in the groin or wrist.
DAY TWO: The second part of the test takes place in the Non-Invasive Cardiology department. You will meet and talk with the doctor who will supervise your test. Small pads (electrodes) are placed on your chest to record your heartbeat and your blood pressure will also be monitored. An IV line is started in your arm.
What a stress test tells your doctor
How long does it take to get stress test results? Results are available within 24 hours of the test.
Trained healthcare providers, typically an exercise physiologist and a cardiologist, are present during your test in the rare event that you have a complication. They assess your performance, data and symptoms throughout the tests and immediately provide emergency treatment if it's needed.
Risks of Stress Test
Your Nuclear Stress Test will take about 3-4 hours to complete.
A nuclear stress test is a more detailed version of the standard exercise stress test. Instead of just measuring your heart's response to exercise, this test takes a closer look at blood flow.
A cardiac stress test can reveal blockages in your arteries through the various types of information it collects. If your blood oxygen level is below normal, the test reveals that your blood flow is partially blocked.
A nuclear stress test can diagnose coronary artery disease and show how severe the condition is. Create a treatment plan. If you have coronary artery disease, a nuclear stress test can tell your healthcare team how well treatment is working. The test also shows how much exercise your heart can handle.
Oftentimes, the next step for people who fail a stress test, and who have risk factors for or symptoms of cardiovascular disease, is an imaging test called a coronary angiography. Your doctor may call it a cardiac catheterization, or “cath” for short.
The test begins with a 10% incline/grade and 1.7mph pace. After 3 minutes, the grade increases to 12% and the speed to 2.5mph. The workloads increase every 3 minutes unless arrhythmias or symptoms preclude continuance or until one reaches a predetermined endpoint such as Target Heart Rate or Stage Goal.
How long will the radioactivity stay in my system? With most of the tracers used, the radioactivity will be almost completely gone by the following day.
Chest pain, or angina, is one of the most common early signs of a blocked artery. It's also one of the most well-known symptoms of a heart attack, which can make it difficult to know if chest pain is an emergency.
Colchicine acts on many anti-inflammatory pathways, which translates to cardiovascular event reduction, plaque transformation, and plaque reduction. With the FDA's 2023 approval of colchicine for reducing cardiovascular events, a novel clinical pathway opens.
A stress test shows how the heart works during physical activity. It also may be called an exercise stress test. Exercise makes the heart pump harder and faster. A stress test can show changes with blood flow within the heart.
