 Clinical decision units CDUs improve resource utilization and are a recommended care option by the American College of Cardiology American Heart Association, but are underutilized in non-low risk chest pain patients due to weaknesses of traditional cardiac testing. Cardiac magnetic resonance imaging CMR is sensitive and specific for ischemia, can simultaneously assess cardiac function and myocardial perfusion, and could revolutionize the diagnostic process for intermediate risk patients with chest pain. The primary objective of this trial is to measure the efficiency and safety of a combined CDU-CMR care pathway compared to inpatient care among patients with non-low risk acute chest pain.
