Clinical Significance

Because of its cardiac specificity and sensitivity, cTnI has been used as a reliable marker in evaluating patients with unstable angina and non-ST segment elevation acute coronary syndrome (ACS). Previous clinical studies of patients with ACS have shown that minor increases in cTnI values provide important prognostic information about the short and long term risk of death. Ultimately, the assessment of the prognosis can be useful in identifying patients most likely to benefit from specific therapeutic interventions
