Ultrasound of Cardiac - Stress Echo Item 3

What Is a Cardiac Stress Echo (Item 3)?

This is a non-invasive cardiovascular imaging test that uses high-frequency sound waves (ultrasound technology) to produce real-time moving images of your heart, both when your heart is at rest and when it is working harder under physical exertion or medication-induced stress. This specific exam does not use ionizing radiation or intravenous contrast dye, and carries no claustrophobia risk, as it only requires a small handheld ultrasound probe placed on the surface of your chest to capture images of all key heart structures.

Clinical Applications for This Cardiovascular Test

This stress echo is used to diagnose and monitor a wide range of heart and cardiovascular conditions, including evaluating for reduced blood flow to the heart muscle caused by narrowed coronary arteries, detecting abnormal heart wall motion that may signal prior heart attack damage, assessing heart valve function during increased heart activity, investigating unexplained chest pain or shortness of breath, and monitoring the effectiveness of treatments for heart failure, arrhythmias, or prior cardiac procedures.

What to Expect During Your 30-Minute Exam

No special preparation is required for this test, so you may eat and drink normally beforehand unless your care team provides specific instructions. First, a trained sonographer will apply a small amount of cool gel to your chest to help the ultrasound probe make contact with your skin, then take resting images of your heart. You will then either walk on a treadmill at gradually increasing speed and incline, or receive a low-dose IV medication that makes your heart beat faster and work harder if you are unable to exercise, while the sonographer takes additional images of your heart as it works under stress. The entire exam takes approximately 30 minutes, and you will not be enclosed in a tight or enclosed space, so there is no risk of claustrophobia during the test.
