Post cath ECG: Now there are hyperacute T-waves again, and recurrent ST depression in V2 This ECG would normally diagnostic of OMI until proven otherwise No further troponins were measured, but it looks like there is recurrent OMI Next day: A CT Coronary Angiogram was done (CTCA) CARDIAC MORPHOLOGY AND FUNCTION: 1. IMPRESSION: 1.

A CT Coronary angiogram was ordered. Here are the results: --Minimally obstructive coronary artery disease. --LAD LAD plaque with 0-25 percent stenosis. The LAD has moderate 40% ostial-proximal LAD stenosis and severe 90% mid LAD stenosis involving first diagonal branch. --The CAD-RADS category 1. --No

This was sent by an undergraduate (not yet in medical school, but applying now) who works as an ED technician (records all EKGs, helps with procedures, takes vital signs) and who reads this blog regularly. Edited by Smith He also sent me this great case. The ST depressions in I and aVL have resolved.

She had a prior history of "NSTEMI" one month ago, during which she had a coronary angiogram reportedly showing no stenosis in any coronary artery. A very similar case to the one presented today appears in the January 17, 2023 post of Dr. Smith’s ECG Blog. Her vitals were within normal limits.

History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. 2 cases of Aortic Stenosis: Diffuse Subendocardial Ischemia on the ECG. We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multi-lead ST depression.

Advanced multi-vessel disease was found with stents deployed to the mid-LCx (80% stenosis), D1 (90% stensosis), and the pLAD (95% stenosis). It’s judicious, then, to arrange for coronary angiogram. elevated BP), but rather directly correlated with coronary obstruction and stymied TIMI flow. Does the ECG normalize?

During angiogram in the cath lab, the patient suffered two episodes of ventricular fibrillation for which he was successfully defibrillated. Angiogram showed a culprit lesion of 100% stenosis to the right coronary artery and 100% stenosis of the right posterior descending artery, both with TIMI 0 flow.
