Read our Coronary Artery Disease research guide →Researchers are testing a new computer software method called Angio-IMR that analyzes heart images to detect problems with the tiny blood vessels in your heart. The study will compare how well this software works when your heart is at rest, after you receive nitroglycerin (a blood vessel-widening medication), and when adenosine is used to maximally widen your blood vessels. The goal is to understand whether the software gives the same accurate results under all these different conditions.
Some patients have problems with the small blood vessels in their heart that are hard to detect with standard heart imaging. Doctors need reliable computer tools to help identify these problems accurately, and this study will determine whether this new software method works equally well regardless of how much the blood vessels are dilated.

You will undergo your already-scheduled heart catheterization procedure as normal. During this procedure, doctors will take special heart images of your target blood vessel at three different moments: when your heart is at rest, after receiving nitroglycerin, and during continuous adenosine infusion to maximally open your blood vessels. A special pressure-sensing wire will also measure your blood vessel function under maximum dilation. The entire study adds only image-capture time to your standard procedure; you will not need additional visits or follow-up appointments beyond what your doctor already planned.
