Tests how accurate heart ultrasound is during stress

This trial studies whether a newer, faster ultrasound imaging method can better assess areas of the heart that may not get enough blood during stress. You may be eligible if you have known coronary artery disease or are considered low risk, and if you can safely undergo the stress ultrasound test.

This study looks at how well a stress echocardiogram (heart ultrasound during exercise or medication) predicts future health in people who have some sign of reduced blood flow to the heart. The goal is to confirm that a positive stress echo is a good sign for guiding next steps.

This study uses computer technology (“machine learning”) with stress echocardiogram images (a heart ultrasound done during stress) to improve how heart function is measured. If you are able to have a stress echocardiogram, you may be able to help test a better way to interpret the results.

This trial studies a stress echocardiogram (an ultrasound of the heart during stress) to better understand and improve future heart imaging. It may help by comparing how well the test works for different heart conditions.

This trial compares two heart imaging tests (stress echo with ultrasound of the neck, and a CT scan) to see which one better helps guide treatment for people with chest pain that might be from heart disease. If you have chest pain that is typical for heart disease, you may be able to join.

This study uses sound recordings from your heart (like a high-tech stethoscope) to see if early signs of heart disease can be detected. You may qualify if you are already having two common heart tests (angiogram and echocardiogram) within a 6-month period.
