Chest pain with suspected acute coronary syndrome, especially in its most severe type – acute myocardial infarction
(MI), is a common cause for which the patient comes to the emergency department. Typical ECG is sufficient to diagnose
MI with ST elevation (STEMI), on the other hand ECG changes of NSTEMI are often atypical. Therefore, another
diagnostic tool to provide reliable information as soon as possible is needed. This approach helps differentiate MI patients
from those with a non-coronary cause of chest pain. High sensitivity methods to measure cTn provide reliable information
after 3 hours, accepting the 0/3 hour protocol, published in 2011. APACE and TRAPID-AMI trials results bring
a brand new 0/1 hour algorithm, published in 2015. Reliability of this “rule-out” protocol was tested at our hospital.
