New heart test could replace painful procedure – no extra wires needed!

This study tests a new technology called IVUS-FFR that uses ultrasound images from inside heart arteries to quickly check if a blockage is serious enough to need a stent. Unlike the current standard test, it doesn't require an extra pressure wire or medication that can cause discomfort. About 292 adults with suspected heart artery disease will have both the new and standard tests to see if the new method is just as accurate.
