Heart stress test results and how they predict heart disease outcomes

This trial is studying patients who have had a stress echocardiography test—a heart ultrasound performed while your heart is under stress—that showed signs your heart isn't getting enough blood flow. Researchers want to learn how well this test predicts whether patients will have future heart problems, and how the results compare with a more invasive heart imaging test called coronary angiography. By following patients for at least a year, the study aims to help doctors better understand which patients need immediate treatment and which can be managed more conservatively.

Stress echocardiography is a common, non-invasive way to detect heart blood flow problems, but doctors aren't always sure how accurately it predicts which patients will have serious heart events in the future. This trial exists to better understand the test's reliability and help guide treatment decisions for patients with known or suspected heart disease.
