Evaluation of Myocardial Ischemia Using Standard Single Photon Emission Computed Tomography (SPECT) With Regadenoson and Simultaneous Cardiac Echocardiography

Status unconfirmed

Conditions studied: Myocardial Ischemia

In brief

This study is for people who have a SPECT scan (nuclear imaging of the blood flow to the heart muscle) ordered by their medical doctors. As part of the SPECT scan, they will have been given a drug called regadenoson to widen and expand the blood vessels bringing blood to the heart muscle. The SPECT pictures of the heart are taken about an hour after the regadenoson is put into an arm vein through an IV. In this study, additional echo pictures will be taken and compared to the SPECT pictures. The aim of the study is to see if the echo pictures work as well as SPECT to measure the blood flow to the heart muscle.
