XXXX in the early evaluation of acute @entity662 .

@entity1 @entity662 @entity296 @entity908 @entity5632 @entity583
Two thirds of @entity1 hospitalized to rule out @entity583 ( @entity583 ) are eventually found to have a non- @entity583 diagnosis, whereas 2% to 8% of @entity1 with @entity583 are inappropriately discharged from the emergency department. @entity5632 has been shown to increase within 2 to 3 hours of @entity296 . This study evaluates the usefulness of @entity5632 in acute @entity662 . Serial blood samples were obtained from 89 suspected @entity583 @entity1 evaluated in the emergency department. Testing included @entity908 kinase (CK), a @entity908 kinase isoenzyme (CK-MB), and @entity5632 . Twenty five of 89 @entity1 (28%) had a diagnosis of @entity583 . The sensitivity of @entity5632 for the detection of @entity583 was 56% at the time of admission and 100% 2 hours after admission. Thirteen of 25 @entity583 @entity1 (52%) had a positive @entity5632 before increases in CK or CK-MB, including one @entity1 discharged from the emergency department. More importantly, the negative predictive value for @entity5632 at the time of admission was 83% and was 100% two hours after admission. This potential for 100% predictability in excluding @entity583 by the use of serial @entity5632 determinations will be very helpful in the correct triage of @entity1 presenting with acute @entity662 .
