Integrated Dual Exercise and Lexiscan Positron Emission Tomography: IDEALPET

Summary

This is a single-center study of subjects undergoing clinically indicated heart scans for evaluation of known or suspected heart disease. We will also include 10 healthy subjects without known heart disease. We would like to study stress testing of the heart using exercise and a medication called regadenoson. Imaging of the heart will be performed.
