Efficacy Evaluation of Observation Unit Cardiac Magnetic Resonance Imaging (MRI) in Patients With Intermediate Risk Acute Chest Pain
6. November 2017 aktualisiert von: Wake Forest University Health Sciences
The purpose of this study is to investigate the best way to evaluate patients with chest pain in the emergency department.
It compares types of cardiac tests performed while receiving treatment in an observation unit.
Patients will either undergo cardiac MRI testing or conventional care testing.
Patients treated in the conventional care testing group will undergo the testing their doctor determines is best for them.
All patients will undergo follow up to find out if they have had any heart related events.

Detaillierte Beschreibung
Despite spending $12 billion annually on the emergency evaluation of chest pain in the US, only 15% of admitted patients have a cardiac cause of their presenting symptoms. Observation units (OU) improve resource utilization, are endorsed by the ACC/AHA guidelines, but have seen limited implementation in non-low risk chest pain patients due to limitations 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 superior accuracy of CMR could decrease testing resulting from false positive results. The high sensitivity for ongoing ischemia could allow imaging in parallel with cardiac markers.
Research hypotheses:
OU-CMR will have superior therapeutic efficacy to OU-conventional testing.
An OU-CMR strategy will have higher diagnostic thinking efficacy than OU-conventional testing.
Methods summary:
To address the question of feasibility of a CMR approach to managing patients at intermediate risk for ACS, we propose a randomized clinical trial of 120 patients at intermediate risk of ACS that present to the ED of Wake Forest University Baptist Medical Center (WFUBMC) for evaluation of chest pain. All patients will receive care in an OU, and will be randomized to CMR, or conventional testing. CMR participants will undergo cardiac markers and CMR testing; conventional testing participants will undergo serial cardiac markers followed by conventional cardiac testing. ACS (infarction, death, coronary revascularization, unstable angina) will be assessed by evaluation of hospital course and phone follow-up at 30 days. Cost of hospital care will be compared among groups.
