It means either a percutaneous coronary intervention with a stent or CABG. Reference : Apart from the heavily quoted classics of COURAGE, BARI-2D, ISCHEMIA, ORBITA 1 etc. You may be. But I am not.You need to undergo some re-vascularisation procedure. What do you mean by that Doctor ? No we can’t.

There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus.

Down-up T-waves in inferior leads are almost always reciprocal to ischemia in the territory underlying aVL. This is not normal and is a tip off that there is posterior ischemia accompanying the ischemia in aVL. It was opened and stented. Data from stress testing proves that the ST depression of ischemia does not localize.

I would expect TIMI-3 flow (normal flow, no persistent ischemia) with a culprit in the RCA (or possibly Circumflex). I would expect that a stent would be placed. The angiogram showed an open artery with 95% stenosis and thrombosis and it was stented. What would I expect the angiogram to show?

More Smith comment: it is true that ST depression (STD) due to subendocardial ischemia does not localize [it is usually diffuse ST depression, in multiple leads and not reciprocal to ST elevation in an opposite territory], this ST depression is different! Both were stented. Notice how useful serial ECGs are! mm ST depression in aVL.

Marked differences can be seen in the prevalence of coronary artery stenosis at autopsy by age and gender. In 30-39 year old women the rate of coronary stenosis at autopsy was 5/1,545 (0.3%) while 60-69 year old men had a prevalence of 12%, almost 40 times higher. The results of this dataset by age and gender follow. This happens.

Queen of Hearts interpretation: Now the cardiologist considered it "STEMI"! No labs were performed. EKG and CT head were performed.

RCA ischemia often results in sinus bradycardia from vagal reflex or ischemia of the sinus node.

He was successfully stented.

This is ischemia until proven otherwise. Here I annotate it: This shows 100% occluded circumflex (red arrow) and a 90% stenosis of the LAD (Yellow arrow). The LAD was thought to be not thrombotic, but a chronic tight stenosis. I learned that the patient is on Sotalol for control of PVCs. This explains the long QT.
