Q: Elevated troponin can be seen beside acute myocardial infarction in all of the following conditions?
A) Sepsis
B) Subarachnoid hemorrhage
C) Pulmonary embolism
D) Aortic dissection
E) All of the above
Answer: E
The objective of above question is to highlight the statement that: "Troponin is highly specific for myocardial cell release, it is not specific for acute coronary syndrome as the cause".
There is a long list of conditions where troponin can be elevated without acute coronary disease.
