The Troponin T HS test index was normal

HS Troponin T/I test is indicated to diagnose myocardial damage, typically myocardial infarction. In which, the Troponin T HS test with high sensitivity and specificity is indicated immediately for patients with suspected myocardial damage to exclude acute myocardial infarction.

The Troponin T HS test, also known as the HS-cTnT test, is an in vitro immunoassay for the quantification of Troponin T (TnT), one of the three subunits of the protein responsible for regulatory functions. muscle contraction.
In the body, Troponin T is present in cardiac and skeletal muscle, so TnT is a specific marker to identify damage occurring in the myocardium. Troponin T HS test is performed together with other tests such as electrocardiogram (ECG), coronary angiography, echocardiogram, blood test, ... as a basis for diagnosis and early detection of infarction heart muscle.

During the first 3-4 hours after an acute myocardial infarction occurs, Troponin T levels increase and can persist for up to 2 weeks. Therefore, the Troponin T HS test is indicated in the following cases:
Diagnosis of acute coronary syndromes and monitoring of disease progression when acute myocardial infarction occurs, unstable angina pectoris but on the electrocardiogram with or without ST elevation. Prognosis of patients with acute coronary syndromes in the near-to-moderate, long-term duration. Measures and alerts the risk of death in patients with chronic renal failure before a cardiovascular event such as myocardial infarction is undetectable by other troponin tests. Evaluation of the effectiveness of the treatment of thromboembolism. Evaluation of coronary heart disease. Prognosis of occurrence or recurrence of cardiomyopathies such as atrial fibrillation.

Depending on age, the normal value of Troponin T HS test will be different, specifically:
Under 50 years old: <14 ng/L 50 - 75 years old: < 16 ng/L Over 75 years old: < 70.6 ng/L When myocardial infarction occurs, cell membranes are damaged due to lack of oxygen, causing cellular proteins to diffuse and spill into the blood. Depending on the extent of heart tissue damage, TnT will increase to varying degrees.
Compared with other TnT tests performed in the past, the current Troponin T HS test allows to detect all possible mild myocardial damage such as heart failure, arrhythmia, .. when the patient has chronic diseases, especially chronic kidney failure, acute chronic lung disease.
In fact, the Troponin T HS test is indicated within 2 - 3 hours after receiving patients with myocardial damage to diagnose, detect and exclude myocardial infarction, because this is a sensitive test. and high specificity.
The performance of Troponin T HS test when receiving patients with signs of myocardial damage may occur in one of the following cases and suggest the diagnosis as follows:
Troponin T HS index is normal, less than 14 ng /L: Conduct the test again after about 3 - 6 hours. If it's unchanged, it's not a heart attack. If Troponin T HS is increased by more than 50% from baseline, acute myocardial infarction is diagnosed. Troponin T HS increases in the range of 14 - 53 ng/L: Repeat the test after about 3 - 6 hours. If Troponin T HS is increased by more than 50% from baseline, acute myocardial infarction is diagnosed. Troponin T HS increased above 53 ng/L: Myocardial damage may occur, but to confirm the diagnosis, repeat testing should be performed after about 3 - 6 hours. If the Troponin T HS is increased by more than 530% from baseline, the diagnosis of acute myocardial infarction is confirmed. In elderly patients, a high Troponin T HS of 86.8 ng/L can confirm the diagnosis of acute myocardial infarction. To diagnose myocardial infarction, in addition to echocardiography, electrocardiogram, coronary angiography, blood tests, including Troponin T HS, are very useful in diagnosing, evaluating and excluding lesions. heart muscle.
As can be seen, the Troponin T HS test has a very important role in diagnosing cardiovascular and coronary diseases. However, in order to receive accurate assessment results, customers should choose reputable medical facilities to be examined and performed.
To protect heart health in general and detect early signs of heart attack and stroke. Currently, Vinmec International General Hospital has been and continues to deploy cardiovascular screening services. The examination helps patients detect cardiovascular problems at the earliest through tests and modern imaging methods.
The examination process at the hospital is performed by a team of doctors, experts with many years of experience combined with a system of modern equipment and machines. As a result, the results produce clear, accurate images, helping to serve the best treatment and treatment.
