The primary objective of this project is to demonstrate that a new approach to cardiac stress imaging that combines treadmill exercise with cardiac magnetic resonance (CMR) provides valuable clinical information in a cost-effective manner.

Condition Intervention
Coronary Artery Disease
Other: Diagnostic Cardiac Imaging

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: EXACT-COST: Exercise CMR's Accuracy for Cardiovascular Stress Testing-Comparative Effectiveness of Stress Tests

Further study details as provided by Ohio State University:

Primary Outcome Measures:
  • Total patient direct and indirect medical costs for one year following stress testing will be less for patients undergoing stress CMR as compared to patients undergoing stress Nuclear. [ Time Frame: baseline ] [ Designated as safety issue: No ]
    Patients will undergo either Stress CMR or stress Nuclear testing. For each individual patient, the cost of the initial test, the subsequent follow-up costs, and the total costs over the follow-up period will be calculated. Total costs will be collected for direct medical, direct non-medical and indirect costs. Direct medical costs will include those applied for medications, imaging, invasive therapies and healthcare services; as well as costs resulting from side effects or complications from each of the testing strategies. Direct non-medical costs will include those incurred due to CAD-related illness or the need to seek care, such as caregiver costs and patient transportation costs. Indirect costs, will be defined as lost productivity due to time lost from work, early death or disability.

Estimated Enrollment: 200

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
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 in patients not referred for cath after 2 weeks)
