Evaluate the Effectiveness and Cost of Stress Cardiac Magnetic Resonance Imaging (MRI) for Non-invasive Evaluation of Lesions Discovered on Computed Tomography Angiography (CCTA)
Stopped early
Conditions studied: Coronary Disease
In brief
This study is designed to evaluate the effectiveness and measurable cost impact of stress cardiac MRI for non-invasive evaluation of intermediate lesions discovered on CCTA in low-to-intermediate risk patients admitted to the ED with suspected ACS. Our primary objective is to determine if the strategy of CTA + stress CMR will reduce the length of time in the ED required to establish a definitive diagnosis, compared to CTA + stress MPI.
