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 reliable. Sometimes the results are "falsely positive" meaning that there is ...

Stress testing is not diagnostic of CAD, as it only implies evidence of stenosis through functional assessments. However, the results can increase or decrease the probability of CAD, termed post-test likelihood, and guide decisions regarding pursuing invasive coronary angiography.[2] ...

Stress echo was initially used for assessing coronary artery disease (CAD), with respect to myocardial viability, using wall motion response; however, current use of stress echo extends beyond CAD, such as valvular heart disease and diastolic stress test. Dobutamine is a commonly used agent when pharmaceutical approach is implemented.

Stress echocardiogram. A stress echocardiogram is done right before and after you exercise at a medical office. It checks how the heart responds to physical activity or stress. Your health care provider may order this test if they think you have coronary artery disease. If you can't exercise, you may be given medicine to make your heart work ...

Stress echo—or echocardiogram—testing uses ultrasound heart imaging. Medical staff take an ultrasound image of the heart at rest. They take another image after the stress of either exercise or after administering a drug that stimulates the heart. Ultrasound is a fast and relatively inexpensive form of imaging.

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).

Overview. A nuclear stress test is an imaging test that shows how blood goes to the heart at rest and during exercise. It uses a small amount of radioactive material, called a tracer or radiotracer. The substance is given by IV. An imaging machine takes pictures of how the tracer moves through the heart arteries.
