Cardiac Troponin Testing Is Overused after the Rule-In or Rule-Out of Myocardial Infarction

[摘要] To the Editor:No good studies have systematically evaluated appropriate clinical utilization of cardiac troponin testing in the clinical setting of the rule-in and rule-out of myocardial infarction (MI)1 (1, 2). Our collective 100-plus years of clinical and laboratory experience suggested that provider test ordering and use of cardiac troponin has been excessive after a diagnosis of MI or no MI has been determined. There is no evidence that supports continuation of cardiac troponin testing after a diagnosis is made (2–5). The goal of this study was to determine whether clinicians appropriately use cardiac troponin I (cTnI) in the assessment of patients at moderate to high risk of acute coronary syndrome (ACS) and MI.After receiving institutional review board approval, we retrospectively reviewed electronic health/medical records in 100 consecutive patients who had serial cTnI orders in the cardiac renal unit, …
