How cardiogenic shock in NSTEMI is different from STEMI?

Dr. S. Venkatesan MD

This can be simply a equivalent of HT, with no true supply side ischemia with LVF with global ST depression ) Management *More or less similar to STEMI with aggressive opening of culprit lesions with few differences. 2013 Nov;6(6):708-15. Epub 2013 Nov 12. PMID: 35743628; PMCID: PMC9224589. Circ Cardiovasc Qual Outcomes.

How does Acute Total Left Main Coronary occlusion present on the ECG?

Dr. Smith's ECG Blog

Post by Smith and Meyers Sam Ghali ( [link] ) just asked me (Smith): "Steve, do left main coronary artery *occlusions* (actual ones with transmural ischemia) have ST Depression or ST Elevation in aVR?" That said, complete LM occlusion would be expected to have subepicardial ischemia (STE) in these myocardial territories: STE vector 1.

Diffuse Subendocardial Ischemia on the ECG. Left main? 3-vessel disease? No!

Dr. Smith's ECG Blog

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

90 year old with acute chest and epigastric pain, and diffuse ST depression with reciprocal STE in aVR: activate the cath lab?

Dr. Smith's ECG Blog

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

Right precordial ST depression in a patient with chest pain

Dr. Smith's ECG Blog

Computer read: "Non-specific ST abnormality, consider anterior subendocardial ischemia" There are very poor R-waves in V1-V4 suggesting old anterior MI. Firstly, subendocardial ischemia does not localize on 12-Lead ECG. But the real question at hand is: Are these precordial ST-depressions a result of subendocardial ischemia?

What does the angiogram show? The Echo? The CT coronary angiogram? How do you explain this?

Dr. Smith's ECG Blog

This suggests further severe ischemia. associated typical Myocardial Infarction therapies such as statins and ACE inhibitors with significantly decreased 1 year mortality in MINOCA patients, which suggests that they do indeed have a similar pathophysiology to MI patients with obstructive coronary disease. Downstream vasospasm?
