. High-sensitivite Cardiac Troponin I is protein released into the blood when the heart muscle is damaged, making it a highly sensitive biomarker used to detect heart muscle injury, particularly in the context of acute coronary syndrome (ACS), such as heart attacks (myocardial infarction) and unstable angina and assessing the severity of heart damage. The test is essential not only for diagnosing heart attacks but also for monitoring recovery and guiding ongoing care.
. It is also used for risk stratification in patients with suspected ACS, helping clinicians make informed decisions about treatment.
. In addition, elevated levels may be seen in conditions like heart failure, myocarditis, or pulmonary embolism, providing insights into the extent of cardiac injury.
