Question 8 of 39:

In this patient cardiac specific troponins may not be detectable for up to 6 hours after onset of chest pain.

You clicked 'False'

Incorrect!

Cardiac specific troponins may not be detectable for up to 6 hours after onset of chest pain.

Thus, when cTnI and cTnT levels are elevated early after onset of discomfort in patients with ST-segment elevation in MI, clinicians should suspect that an antecedent episode of unstable angina was in fact MI and the patient is exhibiting a stuttering course of occlusion and release of infarct-related artery.

Data from the Global Utilization of Streptokinase and TPA for Occluded Arteries (GUSTO) III study suggest that patients with elevated cardiac troponin T levels and who are <6 hours from the onset of discomfort have increased mortality risk.
