Question

A 56-year-old with suspected ACS has normal initial hs‑cTn. When ruling out MI using hs‑cTn, which statement is correct?

Accepted Answer

Serial hs‑cTn below the 99th percentile without significant delta supports rule-out

Answer

A single undetectable hs‑cTn always rules out MI

Answer

Use conventional troponin at 6-12 hours only

Answer

hs‑cTn results should be ignored if ECG is normal

Answer

Rule-out requires stress testing regardless of troponin
