If you have a high troponin level, your healthcare provider might initiate emergency treatment for a heart attack. We anticipate data will continue to evolve about the potential use of such information. We recommend investigators and manufacturers adhere to these recommendations. The cutoff concentrations of these devices should be set at the 97.5% upper reference limits so that the devices can detect the first presence of true myocardial (Class I). Wu has nonsalaried grant relationships with Abbot POC, Siemens, and Abbott Diagnostics. It is the best, established approach given the absence of cTn assay standardization and assays that range from point-of-care, to contemporary, to high-sensitivity assays, and the varying analytical performance across them. , Hochman JS Some have elected to guess what might be best (71,). Most often someones levels will be tested if they report experiencing symptoms of a heart attack or chest pains. , Antman EM An increased cTn concentration is defined as a value exceeding the 99th percentile of a normal reference population (upper reference limit). In the absence of delta criteria, it appears the diagnosis relied on a value (s) >99th percentile URL in the proper clinical context. are clickable links to these studies. , Simoons ML Once elevated above normal levels, troponin may remain high for 10 to 14 days if a heart attack has occurred. , et al. How to best determine this baseline value even in stable patients will need to be defined if changes are going to be considered indicative of risk (69,). Its drawbacks include lack of specificity for cardiac muscle, resulting in false-positive results and inability to detect MI with sufficient sensitivity in the first 6 to 8 h. An absolute level of CK-MB, National Academy of Clinical Biochemistry Standards of Laboratory Practice: Recommendations for the Use of Cardiac Markers in Coronary Artery Diseases, Recommendations for markers in the triage of patients with chest pain, Myocardial Infarction RedefinedA Consensus Document of the Joint European Society of Cardiology/American College of Cardiology Committee for the Redefinition of Myocardial Infarction, Biochemical markers for detecting myocardial necrosis, ACC/AHA Guidelines for the Management of Patients with Unstable Angina and Non-ST-Segment Elevation Myocardial Infarction, Joint ESC/ACCF/AHA/WHF Task Force for the Redefinition of Myocardial Infarction, ESC/ACCF/AHA/WHF Third Universal Definition of Myocardial Infarction, IFCC Educational materials on selected analytical and clinical applications of high-sensitivity cardiac troponin assays, Clinical Laboratory Practice Recommendations for the Use of Cardiac Troponin in Acute Coronary Syndrome, Fourth Universal Definition of Myocardial Infarction, Copyright 2023 American Association of Clinical Chemistry. Normally either troponin I or T levels are tested but not usually both, since levels of each provide the same information. As literature emerges on the many applications of hs-cTn measurements in the outpatient setting (74), the apparent baseline hs-cTn concentration obtained during clinical stability (i.e., not in the emergency room or hospital settings) will be known for many patients. Higher baseline concentrations or deltas can be determined that target higher PPVs and in studies focused only on patients with chest pain, they can provide better specificity (75). Easy way to find specific songs like This is a safe place for all files. The magnitude of the increase in circulating BNP is correlated to the severity of the underlying heart disease. , Huber K Higher cTn concentrations are associated with a higher likelihood of MI and/or diagnoses such as myocarditis (37,). , Bourdillon PD While the 99th percentile URL is not perfect, it supports the diagnosis of acute MI. Institutions that cannot consistently deliver cardiac marker TATs of 1 h should implement POC testing devices. Troponin is an enzyme or protein that is used for the evaluation of heart injury. Challenges exist, however, as also discussed here, given the need for standardized practices as to how to obtain these samples and quality assurance. For contemporary cTn assays, which are still used, the analytical sensitivity is often not sufficient to reliably measure below the 99th percentile URL. , Hamm CW , Sinning C It has provided a consistent cut point for 2 decades and allowed for a standardized approach to diagnosis, assisted with clinical decision making, and trial design across all cTn assays. , White HD High levels of troponin in the blood can indicate that someone has recently had a heart attack, which describes when blood flow to the heart muscle is cut off, causing tissue damage. Measurable troponin levels were also associated with a high risk of myocardial infarction and an even higher risk of heart failure. This problem is intrinsic to all delta calculations, but without a defined threshold to use for additional guidance (i.e., the 99th percentile URL), it becomes even more difficult to operationalize. In the future, there may be cardiac biomarkers that provide valuable prognostic information. It also will evaluate advantages and disadvantages of alternatives, and discuss potential opportunities moving forward. What is a critically high troponin level? , et al.

A blood test is used to check for troponin. A highly sensitive troponin test may be used. Troponin levels are normally too low to be detected, except by the highly sensitive test. If an elevated troponin level is detected, it may mean some kind of heart damage has occurred. Until there are robust data to suggest some other approach, staying with the 99th percentile, a threshold that has served the field well for the past 20years, appears prudent. The normal range is between 0 and 0.4 ng/mL. , Collet JP The troponin concentration can be thought of as a quantitative measure of the degree of injury An important distinction as compared to the use of a delta-only-based MI strategy is that irrespective of whether a change occurs or not using the UDMI, those with increases above the 99th percentile URL will be identified as having myocardial injury. This is associated with increased risk for adverse outcomes (35, 36).
