Troponin T is a myofibrillar protein found in striated musculature. It becomes elevated 2 to 4 hours after the onset of
myocardial necrosis, and can remain elevated for up to 14 days. Patients with low level elevations of troponin T and diagnostic uncertainty for acute coronary syndrome should be evaluated by repeat measurements at 3 and 6 hours. Elevations in troponin
T are also seen in patients with unstable angina. Many other disease states are associated with elevations of troponin T, such as trauma (eg, contusion, ablation, or pacing), congestive heart failure, hypertension, hypotension (often with arrhythmias), pulmonary embolism, renal failure, and myocarditis.
