Summary

This study looks at two new methods to tell apart blockages in large versus tiny heart arteries. About 68 adults with known or suspected coronary artery disease will get a PET scan and a heart catheterization. Researchers will compare the new measurements with standard tests to see if they improve diagnosis.
