Which diagnosis is most consistent with hsTROP 40 ng/L, CK-MB 15 ug/L, and Myoglobin 120 ug/L?

Biomarker patterns are used to distinguish types of cardiac injury. A high-sensitivity troponin T value of 40 ng/L shows definite myocardial injury, not just temporary ischemia. The accompanying elevation of CK-MB and the early rise of myoglobin reinforce that heart muscle cells have been damaged. In stable angina, these markers would stay normal because there is no actual myocardial necrosis. While myocarditis can also elevate troponin, the combination of all three markers elevated in this context most strongly points to myocardial necrosis from an acute myocardial infarction. Pulmonary embolism can cause troponin elevations too, but the full pattern here fits myocardial infarction best.
