What is Use of Cardiac Enzymes Identifies Patients with Acute Myocardial Infarction Otherwise Unrecognized in the Emergency Department about?

Recognition of an acute myocardial infarction in the patient with chest pain is a frequent challenge to the clinician. Previous studies suggest that cardiac enzymes are of limited value in identifying patients with acute MI in the emergency department. Such studies have not evaluated the use of cardiac enzyme tests to complement decision making in the population of patients clinically designated for ED release. We studied 773 ED visits by patients age >~ 30 years presenting with chest pain unexplained by thoracic trauma or radiographic abnormalities. Cardiac enzyme levels were not available to the clinicians at the time of the initial visit and disposition of these patients was determined solely by clinical and ECG evaluation. Of the 291 admitted patients, 46 had an MI; 22 of the MI patients had a normal creatine kinase (CK) level. Of the 482 patients released from the ED, 181 patients had an elevated CK level. Among the released patients were five patients with ML Four released MI patients had a CK level >1 200 IU/L and three had an elevated CK-MB fraction (>1 12 IU/L). In the population of patients scheduled for release, an elevated CK-MB had sensitivity, specificity, and positiv
