Exercise Cardiac Magnetic Resonance Imaging Accuracy for Cardiovascular Stress Testing (EXACT)

This study has been completed.

This study is being done to demonstrate a powerful new method for detecting heart disease that combines the proven prognostic capability of exercise stress testing with the superior image quality of Cardiac Magnetic Resonance Imaging (CMR). The investigators hope to demonstrate that exercise CMR has equivalent or superior diagnostic accuracy compared to exercise stress SPECT for detecting obstructive artery disease.

Condition Intervention
Coronary Artery Disease Other: Diagnostic Cardiac Imaging

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: An In-state Multi-center Evaluation of Treadmill Exercise Stress Cardiac Magnetic Resonance

Further study details as provided by Karolina Zareba, Ohio State University:

Primary Outcome Measures:
  • Exercise stress CMR has equivalent or superior diagnostic and prognostic value compared to exercise stress nuclear scintigraphy in patients suspected of CAD (coronary artery disease) [ Time Frame: baseline ]
    Exercise nuclear and CMR examinations including aggregate assessment of exercise parameters, ECG findings, myocardial perfusion, segmental left ventricular wall motion (CMR only), and viability will be independently reviewed offline by a consensus of two reviewers blinded to the results of the other imaging study, and each test will be classified as either negative/adequate stress, negative/inadequate stress, positive for ischemia, or fixed abnormality/no ischemia.

Enrollment: 227
Study Start Date: August 2010
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Diagnostic Cardiac Imaging
    Cardiac Magnetic Resonance (CMR) offers superior image quality compared to echocardiography and nuclear imaging, and the ability to image both function and perfusion. Combining the superior image quality of CMR with the diagnostic information provided by exercise stress could result in a new, more accurate modality for diagnosing and evaluating coronary artery disease. This project is expected to show that CMR is at least equivalent to nuclear stress imaging and could potentially replace it in many instances, eliminating the need for radioisotope administration and the associated exposure of patients to ionizing radiation.

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

Inclusion Criteria:

  • any patient referred for stress SPECT
  • known or suspected ischemic heart disease
  • ability to perform adequate treadmill stress

Exclusion Criteria:

  • any contraindication to MRI (e.g. ferromagnetic foreign body, cerebral aneurysm clip, pacemaker/ICD, severe claustrophobia)
  • renal insufficiency (GFR < 40)
  • known allergy to gadolinium-based contrast or iodinated contrast (because of the research CTA (computed tomography angiography) in patients not referred for cath after 2 weeks)
