Hgb 11g/dL (110g/L) and leukocytosis, and a mildly elevated troponin (36 ng/L, with normal 1mm STE in aVR due to ACS will require coronary artery bypass surgery for revascularization, the infarct artery is often not the LM, but rather the LAD or severe 3-vessel disease. 2 cases of Aortic Stenosis: Diffuse Subendocardial Ischemia on the ECG.

Whenever there is tachycardia, I am skeptical of OMI unless it has led to severely compromised ejection fracction with cardiogenic shock.
