Clinical Applications of High-Sensitivity Troponin Testing: From Diagnosis to Prognosis.

High-sensitivity cardiac troponin (hs-cTn) is critical in the diagnosis of acute coronary syndrome. However, it can also inform risk of cardiovascular events and mortality. Patients with unstable angina and normal-range hs-cTn have a very favorable short-term prognosis and do not appear to suffer increased risk of cardiovascular events and mortality. Such patients can often be treated in the outpatient setting.
