Acute coronary syndromes and diagnostic methods

Abstract

On behalf of The DANSPOT Steering Commitee Funding Acknowledgements: Type of funding sources: Foundation. Main funding source(s): Danish Heart Foundation Independent Research Fund Denmark Background: Measurements of high-sensitivity cardiac troponin (cTn) T/I are used as the gold standard and are the preferred biomarkers to diagnose acute myocardial infarction (MI) in conjugation with symptoms and changes in the ECG. The URL is based on the 99th percentile of troponin concentrations in a healthy reference population. Currently, a sex-uniform manufacturer provided 99th percentile URL of troponin is utilized at Danish hospitals as a diagnostic cutoff for acute MI for both men and women. Reportedly, healthy men have twofold the troponin level compared to healthy women, suggesting that the use of a uniform URL for troponins may lead to the under-diagnostication of acute MI in women and potentially over-diagnostication in men.
