High Sensitivity Troponins in Acute Chest Pain

This month JC will be looking at highly sensitive troponins and their potential applicability when assessing patients in the ED with acute chest pain. According to the CDC’s most current data the chief complaint of “Chest Pain” represents approximately 5.5% of all ED visits and may be as high as 10%. According to a recent study, in-patient or observation unit admission rates for ED patients is pretty high ranging from 40% to 80% which reflects our low risk tolerance for acute chest pain patients. The most recent European Society of Cardiology guidelines (see 3.3.2) recommends the use of high sensitivity troponins and an expedited 0/1 hour diagnostic algorithm with very high negative predictive values.  We have included  the links above as well as three articles that will be critically appraised. Also included, is a recent JACC review article by EVMS’s own Dr. John Brush titled: Troponin Testing for Clinicians.

So, is high-sensitivity troponin ready for prime-time or not? Should make for an interesting discussion and an opportunity to settle our differences at Laser Quest
