Even if it could check a trop, that's a pretty late indicator. If you're having the big one, you're going to be dead before your troponin spikes.

- HeyLaughingBoy 7y agoIs that right? When I worked in medical instrumentation, I was always told that TnI was a leading marker.
- JshWright 7y agoIt will take up to 8 hours for troponin levels to rise after the onset of symptoms (typically 3-4).
- btach 7y agoER nurse here - some STEMIs I've taken care of had negative initial trop's (not all though). The 4 hr delta should of course be positive though - I don't typically check the 4 hr repeat for STEMIs though because they're long gone out of the ED to the cath lab then to CVICU.
