We present the cumulative percutaneous coronary intervention (PCI) data of all comers (stable angina and acute coronary syndromes [ACS]) who presented to Hadi Clinic between January 2018 and December 2020. and the average number of stents 2.6. The radial approach was used in 544/567 (95.94%), the average SYNTAX score was 34.8 ± 9.6,

A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.

Types of ACS include stable angina 5.3% (n=8), unstable angina 24% (n=36), NSTEMI 28.7% (n=43), and STEMI 24% (n=36). All patients had interventional PCI with balloon and stent insertion. The mean age of patients was 57.68 (SD= 11.19) years. Rate of MACE as composite outcome 30-days after PPCI as 24.7% (n=37).

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 It was stented. This T-wave inversion morphology is very specific for Wellens' waves. Gottlieb SO, et al.

Here is the prehospital ECG, with pain:  Hyperacute anterolateral STEMI  The medics had activated the cath lab and the patient went for angiogram and had a 95% stenotic LAD with TIMI-3 flow. A stent was placed. When the patient had chest pain, prior to nitroglycerine, what do you think the ECG showed ? Lessons: 1. de Zwaan C.,

Despite ongoing chest discomfort and an uptrending troponin, he never meets STEMI criteria.

While this ECG is negative for “posterior STEMI”, the resolution of anterior ST depression (accompanied by the troponin elevation) confirms posterior OMI with spontaneous reperfusion. The second opportunity to make the diagnosis and expedite angiography was missed because the ECG never met STEMI criteria and continued to be labeled ‘normal.’

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?

It is equivalent to a transient STEMI. Not much, but studies of STEMI and NonSTEMI show that about 70% of those diagnosed with STEMI have a peak troponin I above 10 ng/mL and that about 70% of those diagnosed with NonSTEMI have a peak troponin I below 10 ng/mL. The lesion was stented. Again, cath lab was not activated.

The PMCardio Queen of Hearts app asks you, before giving an interpretation of OMI ("STEMI-Equivalent"), whether the patient's clinical presentation is high risk for OMI. Was it unstable angina? Well, really, in this case, there was no angina, only "dizziness") I don't think so. So let's pretend this is acute chest pain.
