The emerging role of highly sensitive troponin in the evaluation of acute coronary syndrome.

Abstract

Cardiac troponin is the biomarker of choice for the serological diagnosis of acute myocardial infarction. With the development of "highly sensitive" troponin assays, it is now possible to measure levels of this marker at and below the current 99th percentile of a healthy population; high sensitive troponin assays show great potential in earlier detection of acute myocardial infarction and better risk prediction in patients with acute coronary syndrome.
