The 2022 American College of Cardiology (ACC) pathway provides timely guidance [1]. Intermediate-risk patients may be further stratified based on recent stress testing or coronary angiogram findings plus a modified HEART or Emergency Department Assessment of Chest Pain (EDACS) score. Time to know your hs-cTn better.

And so it is wise to look at the coronary arteries. Here they are: Learning Points: 1. This ECG certainly looks like myocarditis, and was due to myocarditis, but missing acute coronary occlusion is not acceptable. 3–8 Shi et al. In acute MI, the T-wave is large, and the T/ST ratio is high. Angiogram was negative.
