Extremely high troponin levels induced by septic shock: a ca
Troponin levels can be elevated in various diseases other than acute myocardial infarction, including sepsis. In diseases without myocardial necrosis, the elevated troponin levels are relatively low and normalize quickly.

A 61-year-old Japanese man with impaired consciousness was transported to our hospital. He was diagnosed as having pneumonia and septic shock. His condition was severe, but his clinical course was good. However, his troponin level remained extremely high during admission; on the second day, it was higher than the measurable range. He consulted a cardiologist and performed echocardiography and myocardial perfusion scintigraphy but found no new ischemic changes.

In septic shock, troponin levels can be extremely high, which can persist even after recovery, as in very large myocardial infarctions.
