Background Hyperglycemia, characterized by elevated blood glucose levels, is frequently observed in patients with acute coronary syndrome, including ST-elevation myocardial infarction (STEMI). There are conflicting sources regarding the relationship between hyperglycemia and outcomes in STEMI patients.

MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection; myocardial disorders, including myocarditis, takotsubo cardiomyopathy, and other cardiomyopathies. MINOCA I do not have the bandwidth here to write a review of MINOCA.

Here is his ED ECG at triage: Obvious high lateral OMI that does not quite meet STEMI criteria. Thus, it has recently become generally accepted that most plaque ruptures resulting in myocardial infarction occur in plaques that narrow the lumen diameter by 40% of the arterial cross section may be involved by plaque.

You've read in my previous posts that I have a lot of evidence that Wellens' represents spontaneously reperfused STEMI in which the STEMI went unrecorded. New ST elevation diagnostic of STEMI [equation value = 25.3 Consequences of reocclusion after successful reperfusion therapy in acute myocardial infarction.

Such cases are classified as MINOCA (Myocardial Infarction with Non-Obstructed Coronary Arteries). MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection. An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!!

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

This is a troponin I level that is almost exclusively seen in STEMI. In this case, profound shock for 1 hour would result in the same degree of infarction. A followup ECG was recorded 2 days later: No definite evidence of infarction. So this is either a case of MINOCA, or a case of Type II STEMI. Troponin I rose to 44.1
