Otherwise, no admission of CAD, HLD, or family history of sudden cardiac death. link] deWinter first reported his unique characteristics of LAD occlusion in 2008, and since the respective ECG changes do not fit the conventional STEMI paradigm (as he even stated – “instead of signature ST-segment elevation” ….)

Furthermore, there was no family history of early CAD, MI, or sudden cardiac death. BP 142/100 HR 90 RR 16 (BBS CTA) SpO2 99 (RA) Dstick 110 My colleagues noted the ST-depression in the respective leads, as well, and STEMI activated to the nearest PCI center. 1] Here is the admitting ED ECG after cancellation of Code STEMI.

The ED provider ordered a coronary CT scan to assess the patient for CAD. His EKG with worse pain now shows enough ST elevation to meet STEMI criteria. The EKG was read by the conventional computer algorithm as diagnostic of “ACUTE MI/STEMI”. The patient started receiving medications for “STEMI” (including heparin!!!)

However, a smooth tapering of the mid-RCA was seen, highlighted in red below: How do we explain the MI if no sign of CAD was found? This MI wasn’t caused by a ruptured plaque of CAD - it was a coronary artery dissection of the RCA. A recent study found that SCAD causes almost 20% of STEMI in young women. A study by Hassan et al.

This is technically a STEMI, with 1.5 However, I think many practitioners might not see this as a clear STEMI, and would instead call this "borderline." They collected several repeat ECGs at the outside hospital before transport: None of these three ECGs meet STEMI criteria. This ECG was recorded on arrival: What do you think?

J Electrocardiol [Internet] 2022;Available from: [link] Cardiology opinion: Takotsubo Cardiomyopathy (EF 30-35%) V Fib Cardiac arrest Prolonged QTC NSTEMI (Smith comment: is it NSTEMI or is it Takotsubo? -- these are entirely different) Moderate single-vessel CAD. I could have told you this (and did tell you this) without an MRI.

These findings are very subtle but suspicious for LAD occlusion, as we have seen in many similar (but less difficult) cases on this blog: A man in his sixties with chest pain at midnight with undetectable troponin How long would you like to wait for your Occlusion MI to show a STEMI? He also had non-acute CAD of the RCA (50%) and LCX (50%).
