Further study details as provided by The Methodist Hospital System:

Primary Outcome Measures:
  • Profile of sensitivity, specificity, and diagnostic accuracy of rapid regadenoson stress CMR. [ Time Frame: Up to 7 days ]
    Evaluate the profile of sensitivity, specificity, and diagnostic accuracy of a rapid regadenoson stress CMR protocol for the detection of >= 70% stenosis of a major epicardial coronary artery on invasive coronary angiography.

Secondary Outcome Measures:
  • Evaluate time for performance of rapid regadenoson stress CMR protocol. [ Time Frame: Up to 7 days ]
    Evaluate duration of time for performance of rapid regadenoson stress CMR protocol in comparison to time for performance of standard regadenoson stress CMR protocol.

Estimated Enrollment: 50
Study Start Date: August 2011
Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Additional images collected during routine cardiac MRI (CMR) with diagnostic imaging agent, regadenoson.
Drug: regadenoson
Intravenous administration of 0.4 mg dose of Regadenoson using per routine CMR, as indicated in the package insert.
Other Name: Lexiscan

Detailed Description:
This is a single center, open-label, pilot study in subjects scheduled for invasive coronary angiography for evaluation of coronary artery disease. The primary objective is to evaluate the profile of sensitivity, specificity, and diagnostic accuracy of a novel rapid regadenoson stress CMR protocol for detection of >= 70 coronary artery stenosis on invasive coronary angiography. Additionally the objective will be to compare the time for performance of this novel rapid regadenoson stress CMR protocol in comparison to the standard stress CMR protocol.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Aged 18 years or older
  • Scheduled for invasive coronary angiography

Exclusion Criteria:

  • Inability to give informed consent
  • Possible pregnancy (confirmed by urine test)
  • Women who are breastfeeding
  • Severe claustrophobia
  • Inability to lie flat for 20-30 minutes (the anticipated amount of time to complete the MRI procedure)
  • Individuals with cochlear implants
  • Individuals with non-MRI compatible aneurysm clips
  • Potential contraindications to regadenoson use due to:

Severe lung disease (active wheezing) Severe bradycardia (heart rate < 40 beats/min) Second- or third-degree atrioventricular heart block Sick sinus syndrome History of Long QT syndrome Severe hypotension (systolic BP < 80 mm Hg) Decompensated heart failure

  • Contraindication to administration of Gadolinium (Gd) based contrast agents (GBCA):

Stage 4 or 5 chronic kidney disease (eGFR < 30 ml/min/1.73 m2) Known allergy to GBCA

Special Considerations:

- Although individuals who have an occupational history of welding, grinding, or other metal work will not be excluded from the study, they must undergo an orbital x-ray, to exclude any occult metal fragments, before they can participate in this study.
