Investigation of acute coronary syndrome in patients presenting with chest pain

Please see the UHNM Guide for the Interpretation of Cardiac Troponin I (cTnI) for information.

The universal definition of MI requires detection of rise and/or fall of cardiac biomarkers values [preferably cardiac troponin (cTn)] with at least one value above the 99th percentile of the upper reference limit and at least one of the following: symptoms of ischaemia; new or presumed new significant ST‑segment‑T wave (ST‑T) changes or new left bundle branch block (LBBB); development of pathological Q waves in the ECG; imaging evidence of new loss of viable myocardium or new regional wall motion abnormality or identification of an intracoronary thrombus by angiography (from Thygson K et al. European Heart Journal 33: 2551-2567)

Other causes of elevated troponin include myocarditis, aortic dissection and pulmonary embolism
