An Elevated Value of Troponin I, Troponin T, CK-MB, and/or Myoglobin
Troponin I or T is now widely used over other markers for acute MI in the absence of other markers.
Any elevation can indicate myocyte damage; interpret results with defined institutional cutoffs for myocardial infarction.
Suggested Additional Lab Testing
Appropriate follow-up testing with troponin level.
Test as appropriate to rule out causes of increased troponin not caused by cardiac ischemia.
If ECG is abnormal in the presence of positive markers, this is strongly indicative for AMI.
If ECG is normal or shows a pattern not indicative for AMI with a suggestive clinical picture for MI, do serial testing for troponin pressure sensation within the chest with appropriate radiation of pain, which is suggestive of AMI.
Rule out other potential causes of an elevated troponin.
