This was interpreted by the treating clinicians as not showing any evidence of ischemia. Given the presentation, the cardiologist stented the vessel and the patient returned to the ICU for ongoing critical care. He did not remember whether he had experienced any chest pain. Two subsequent troponins were down trending.

Submitted and written by Anonymous, edits by Meyers and Smith A 50s-year-old patient with no known cardiac history presented at 0045 with three hours of unrelenting central chest pain. The pain was heavy, radiated to her jaw with an associated headache. Triage VS: 135/65 mmHg, 95 bpm, 94% on room air, 16/min, 98.6 Abstract 556.

The only time you see this without ischemia is when there is an abnormal QRS, such as LVH, LBBB, LV aneurysm (old MI with persistent STE) or WPW." The patient was managed in the ICU and had serial troponins. Here is the patient's troponin I profile: These were interpreted as due to demand ischemia, or type II MI. First was 2.9

No chest pain. Normally, concavity in ST segments suggests absence of anterior ischemia (though concavity by itself is not reassuring - see this study ). Later on during the night of his admission he had a short episode of chest pain that resolved with sublingual nitroglycerin. His vitals were initially normal.

He did not have chest pain. A prior ECG was available for comparison: Normal One might be tempted to interpret the ST depression as ischemia, but as Smith says, "when the QT is impossibly long, think of hypokalemia and a U-wave rather than T-wave." Chest pain in high risk patient. Is it STEMI?

A middle-aged woman with history of hypertension presented to another hospital approximately 2 hours after onset of chest pain and shortness of breath. Back to the case: The providers recognized persistent ischemia and likely occlusion, and discussed this with cardiology who took the patient immediately for cath. They opened it.

Are you confident there is no ischemia? Primary VT , and the VT with tachycardia is causing ischemia with chest discomfort (supply-demand mismatch/type 2 MI)? Ischemia from ACS causing the chest discomfort, with VT another consequence (or coincidence)? Do you agree with this strategy?
