Key result
Recent guidelines endorse troponin as the biomarker of choice for diagnosing acute myocardial infarction, emphasizing the 99th percentile value and classifying AMI into five subtypes.
Why the study?
How do recent guidelines define the universal diagnosis of acute myocardial infarction using troponin?
How do recent guidelines define the universal diagnosis of acute myocardial infarction using troponin?
Understanding the updated guideline criteria for troponin use is essential for a consistent approach to diagnosing the five subtypes of acute myocardial infarction.
Supports troponin 99th percentile for AMI diagnosis in practice; extends prior criteria by formalizing five subtypes for research.
BACKGROUND: All of the recent guidelines now endorse the use of troponin as the biomarker or choice for the diagnosis of acute myocardial infarction (AMI). METHODS: Review of the recent guidelines criteria. RESULTS: Rising and/or falling values of troponin in patients who appear to have ischemic heart disease will result in the diagnosis of AMI. The recent guidelines emphasize the use of the 99th percentile value for troponin and suggest it should be measurable with a high level of precision. They also suggest how to operationalize determining a significant change for patients who appear to have recurrent infarction and classify AMI into five subtypes. CONCLUSIONS: Understanding these criteria will be important to a consistent approach to the diagnosis of AMI in the future.

Allan S. Jaffe (2008) conducted a review in Acute myocardial infarction. Troponin was evaluated. Recent guidelines endorse troponin as the biomarker of choice for diagnosing acute myocardial infarction, emphasizing the 99th percentile value and classifying AMI into five subtypes.
