NCT00881218

Brief Summary

This is a pilot study to determine whether the drug regadenoson can be used during magnetic resonance imaging to assess regions of poor blood flow to the heart. The hypothesis of this study is that a single injection of regadenoson could be used instead of a standard adenosine infusion to produce coronary vasodilatation and demonstrate myocardial ischemia during first-pass perfusion cardiac MRI.

Outcome Measures

Primary Outcomes (1)

    1 year

Study Arms (1)

Regadenoson CMR

EXPERIMENTAL

Images in the cardiac short axis will be obtained using a gradient recalled echo sequence, TR 2.3 msec/TE 1.1 msec, 80\*256 matrix, slice thickness 10 mm. Images will be obtained during power injection of 0.075 mmol/Kg of a conventional gadolinium based MR contrast agent at a rate of 5 mL/sec followed by a 15 mL saline flush into an antecubital vein. Perfusion imaging will be performed at stress and rest. Stress: Regadenoson 400 mcg will be administered IV bolus via an antecubital cannula. Immediately after injection, MR scanning will begin and contrast will be given. Rest: After 10 minutes, rest imaging will be performed identically, but without regadenoson injection. To identify late enhancement of myocardial tissue inversion recovery prepared images will be obtained.

Drug: Regadenoson

Interventions

Regadenoson 400 micrograms will be administered IV bolus via an antecubital cannula.
