HS Cardiac Troponin T, High-Sensitivity Troponin T, High-Sensitivity Cardiac Troponin T

HS Troponin T

Troponins are part of a group of proteins that regulate heart contraction. Troponin T is released into the blood when there is heart damage. Its measurement in blood is particularly useful in diagnosing acute myocardial infarction. Troponin T develops between 2 and 4 hours following the symptoms of an infarction. The maximum concentration is reached after 12 to 18 hours and the level remains high for 5 to 14 days after the infarction. This test can also be used to assess heart problems other than an infarction, such as cases of angina. An increase in troponin T in angina cases may be indicative of a high risk of more severe heart problems. This test has a high sensitivity (hs) and therefore can be used to measure a very slight increase in the blood, allowing heart problems to be detected very early, almost as soon as they occur. Note that an isolated hs troponin T result is not sufficient to diagnose or rule out a heart problem. A more comprehensive clinical assessment is required. Also, an infarction can occur without an increase in troponin T and, conversely, an increase can be observed without any apparent heart problems.

Term of the Week

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
