title: Is it more accurate to measure the absolute or the relative change of new high or ultrasensitive troponin assays to diagnose acute myocardial infarction?
abstract: OBJECTIVE
  In emergency department patients with symptoms suggestive of acute myocardial infarction, is the absolute or relative change of cardiac troponin assays (either high sensitivity or ultrasenstive) more accurate in diagnosing acute myocardial infarction at 1 to 2 hours postpresentation?
