Read our Coronary Artery Disease research guide →This research study is testing a newer, faster ultrasound technology to see if it can better detect blocked blood vessels in the heart. Researchers will use an experimental ultrasound system called the Verasonics Vantage, alongside standard ultrasound machines, to take detailed pictures of your heart. They'll compare how well this new technology works compared to current methods.
Current heart ultrasound imaging has limitations in detecting blocked blood vessels, especially during stress testing. This trial exists to see whether the new ultrasound technology can provide clearer, more detailed pictures that might help doctors diagnose heart disease more accurately and earlier.

You will have an IV line placed in your arm and then undergo heart ultrasound imaging. First, you'll get baseline ultrasound pictures using two different ultrasound machines. Then you'll receive an injection of contrast dye through the IV, followed by more ultrasound images. Finally, you'll receive a medication (dipyridamole) to stress your heart while more ultrasound images are taken. The entire visit will involve lying still while the ultrasound technician scans your heart with the probe.
