High sensitivity cardiac troponins for ED chest pain evaluation (2022 ACC pathway)

ALiEM

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.

Compensatory enlargement was defined as being present when the total coronary arterial cross-sectional area at the stenotic site was greater than that at the proximal nonstenotic site. We documented that the majority of stenotic lesions had compensatory enlargement and thus exhibited remodeling. As was emphasized by Dr.
