A stress echocardiography, also called an echocardiography stress test or stress echo, is a procedure that determines how well your heart and blood vessels are working. During a stress echocardiography, you’ll exercise on a treadmill or stationary bike while your doctor monitors your blood pressure and heart rhythm.
What is a stress echo test?
A stress echo test, otherwise known as an echocardiogram, is a noninvasive procedure designed to test whether your blood vessels and heart are getting adequate blood flow and oxygen when stressed. It’s generally given to patients with suspected coronary heart disease, or CHD (also known as coronary artery disease).
What does a positive stress test result mean?
Results obtained from a nuclear stress test highlight the specific cardiac areas, which increase in an adequate way at the time of doing exercises. The positive stress test result obtained from the stress test highlights coronary heart problems; however, not all of the patients suffering from any positive stress test have CAD problems.
Can you have a heart attack from a stress echo?
However, stress echo tests only reveal severe narrowing of arteries. Heart attacks can happen from less severe blockages. This is important to keep in mind because, depending on why you received the echocardiogram in the first place and the concerns of your health care provider, your doctor may order additional tests.
What is an ECG stress test?
The standard test is an ECG—or electrocardiogram—stress test. An ECG stress test monitors your heart’s electrical activity during exercise. Medical staff will also monitor your blood pressure and breathing.

Your doctor might recommend a stress echocardiogram to check for coronary artery problems. However, an echocardiogram can't provide information about any blockages in the heart's arteries.
Is a positive stress test good?
So, positive results generally mean more testing is necessary to confirm if there is a real problem, or not, and guide treatment. This may involve either a stress echocardiogram or a nuclear stress test because these tests are more accurate. Sometimes, more invasive testing is necessary.
How accurate is a stress echo test?
Stress Echo tests are able to detect individuals with heart disease about 70% of the time. This means that, if you actually DO have heart disease, the test will accurately detect it seven out of ten times. It should be noted that the Stress Echo test is not 100% reliable.
What is a good score on a stress test?
Low risk (score > 5) indicates a 5-year survival of 97%. Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. High risk (score < -11) indicates 5-year survival of 65%. In high-risk patients, 74% had 3-vessel or left main occlusive coronary disease on angiography.
What happens after a positive stress test?
After a stress test indicates an abnormality, heart specialists turn to a more invasive but also much more informative test, a heart catheterization with angiography. A long, thin tube called a catheter is threaded through blood vessels to the heart. Using a special dye, doctors can see the blockages precisely.
What if stress test is negative?
A negative exercise or even pharmacological radionuclide stress may not mean very much if we consider the dynamic nature of this disease. Therefore, a negative result should not exclude the diagnosis of significant coronary artery disease.
What can a stress echo reveal?
Stress echocardiography is a test that uses ultrasound imaging to show how well your heart muscle is working to pump blood to your body. It is most often used to detect a decrease in blood flow to the heart from narrowing in the coronary arteries.
Can you have heart blockage with a normal stress test?
This condition can cause chest discomfort with a normal stress test result. A normal stress test result only shows that there is not a significant coronary artery blockage. A smaller blockage could be present that isn't picked up by the stress test.
What is difference between stress test and stress echo?
A stress echo is a more dynamic test that examines the heart in action. It combines an ultrasound of the heart with a stress test. A stress test, often called a treadmill test, measures how your heart works when experiencing added workload or “stress” of exercise.
Which is better stress test or calcium score?
Calcium scans can be more effective at identifying plaque build-up than compared to a stress test in some instances. For example, if all of a person's arteries are blocked, a stress test's measurement would look the same across the board and not show a concern.

What test shows blocked arteries in the heart?
A CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack. Prior to the test, a contrast dye is injected into the arm to make the arteries more visible.
Can you have heart blockage with a normal stress test?
This condition can cause chest discomfort with a normal stress test result. A normal stress test result only shows that there is not a significant coronary artery blockage. A smaller blockage could be present that isn't picked up by the stress test.

What Does a Stress Echo Diagnose?
Stress echo diagnosis will help to measure changes in the blood flow to the heart. If you have a history of heart ailment or heart attack, it is preferable to undergo the stress echo diagnosis to ensure that you do not possess any underlying causes. Furthermore, the stress echo diagnosis helps in ensuring that blood is pumping continuously even when the body is at rest and under pressure.
How does the Stress Echo Diagnosis Results Help?
As the cardiograph measures the electrical impulses created in the heart when the body is resting and undergoing strenuous activity, it displays whether the heart is receiving the same amount of oxygen through blood flow. If not, it will help the cardiologist to locate the region of narrow passages.
What is cardiac stress test?

What does it mean when a stress test shows a lack of blood flow?
Imaging data: If imaging was part of the stress test, doctors will include this data. The main focus is perfusion—or the presence of adequate blood flow. They will look for areas with poor blood flow and note their size and location. Decreased or absent blood flow can indicate blockages or heart muscle damage or death.
