[A very high level in a cardiac troponin I assay].
Cardiac troponin I (TnIc) is a very sensitive and also a specific marker of myocardial injuries. We report here, the clinical case of a patient with a particularly important and brutal increase of the troponin during a myocardial infarction. A 64-year-old man was admitted to hospital. He had a myocardial infarction associated to a cardiac necrosis and important cytolysis. The troponin assay was normal when the patient was hospitalized. The angioplasty coronary reperfusion brought about a massive troponin Ic release in systemic circulation: the assay made 10 hours after the appearance of the symptoms shows us an exceptional TnIc concentration that is greater than 4000 microg/L (baseline: 1,5 microg/L). This might be the highest value ever reported.
