Elevated Troponin I in the Absence of Coronary Artery Disease: A Case Report With Review of Literature.

Cardiac troponins are the most sensitive and specific markers of myocardial injury. In fact, the Joint European Society of Cardiology/American College of Cardiology committee for the redefinition of myocardial infarction (MI) states that troponins are the preferred cardiac marker for detecting myocardial injury. For the aforementioned reasons, troponin levels are routinely ordered for patients presenting to the emergency department with chest pain, dyspnea, syncope, or any other possible presentations of MI.
