This study will assess the value of magnetic resonance imaging (MRI) in detecting heart attack and heart attack risk in patients who come to the hospital emergency room because of chest pain. It will also investigate whether MRI can help predict the coronary status of patients 4 to 6 weeks and 1 year after emergency room admission.
Patients who come to the emergency room of Suburban Hospital in Bethesda, MD, because of chest pain may be asked to enroll in this study if they have not been diagnosed as having a heart attack. Participating patients will undergo a MRI scan as soon as emergency room doctors determine they are in stable condition. For this procedure, the patient lies on a table that slides into the MRI scanner-a large tubular machine with a magnetic field. During the scan, a contrast material is injected into the vein. This material brightens the image of the heart so that the blood flow can be seen. The scan will show if there are areas of heart muscle that received insufficient blood flow. A second scan will be done within 72 hours to look for coronary artery blockage that may require treatment. Patients will be followed by telephone 4 to 8 weeks after the scans and again 1 year after the scans to ask about any significant medical problems that may have occurred during those time periods.
This study will provide information that may improve emergency treatment of patients with acute chest pain by clarifying which patients require immediate medical treatment, which should be admitted to the hospital for further evaluation, and which may safely be discharged from the hospital.
Coronary artery disease remains the leading cause of death in the United States and results in high diagnostic and therapeutic costs. The overall costs associated with the care of patients with cardiovascular disease is projected to be $286.5 billion. Although MRI is a relatively expensive technology, this methodology can provide all the noninvasive diagnostic testing necessary to evaluate and triage patients with coronary artery disease. This "one stop shop" has the potential to lower overall testing on this important patient population and better delineate which patients require intervention. Beyond reproducing the results of existing diagnostic tests, MRI has unique abilities to characterize myocardial tissue adding information in the assessment of these patients that is not attainable by currently available methodologies. This study will examine the hypothesis that MRI assessment of regional LV function, resting myocardial perfusion, and myocardial tissue characteristics can accurately detect a higher fraction of patients with acute myocardial infarction than is possible with the ECG performed in the emergency department.

Respiratory syndrome characterized by the appearance of a new pulmonary infiltrate on chest x-ray, accompanied by symptoms of fever, cough, chest pain, tachypnea, or DYSPNEA, often seen in patients with SICKLE CELL ANEMIA.
