Discussion for 51 Year Old Male: Chest Pain

Here is the conclusion to 51 year old male: Chest Pain. You may wish to review the case.

Here is the ECG again:

 

There is a regular sinus rhythm at a rate of about 70. The QRS is narrow. The axis is normal, at about 15 degrees.

Let's take a look at the constellation of ST changes:

There is ST elevation in leads I, aVL, V2-V6. There is slight ST depression in III and aVF (and arguably in lead II) with ugly looking T wave inversions. Some of you also noted the suspicious looking Q waves in III and aVF.

Pericarditis and Early Repol were put forth as possibilities. Remember though, that neither of those will have reciprocal changes (excepting myocarditis, which may present as STEMI). Here, we have reciprocal changes inferiorly. If you were inclined to be thinking about STEMI mimics in this case, those changes should put ischemia at the top of the list.  In addition, as some of you pointed out, the ST changes do not look like Early Repol, and the amount of ST elevation here is alarming.

The crew in this case, along with the physician, decided this was STEMI. The patient was given Heparin, ASA, anti-emetics, and Morphine. His condition improved enroute, and his BP climbed to 124/75.

Upon arrival at the hospital, he was taken directly to the cath lab. There was a complete blockage of the LAD.

 

Here is the cath lab image showing the blockage:

Here is the image after revascularization:

 

I don't know about you, but I always find these images amazing. Fortunately, our patient was discharged from the hospital to cardiac rehab a few days later. He was expected to recover nicely. 

Enjoy the holiday!

I'm with Dave Eastman on this. I think it's hyper K+ and will treat as such. But I'll do that will I head to the PCI capable facility. Do I think there is an underlying STEMI? Nope, I sure don't. Do I know the computer has a hard time with false positives? yup. Am I…

1) Change to every lead? STEMI is questionable on my Dx # 6 on a list of 5. IF my recall on this, IF a Global presentation of ST change with QRS Change: a) STEMI is extremely unlikely or NOT STEMI b) start looking for mechanical problems ( tamponade) or chemical/ electrical (electrolyte imbalance or…

My first thought was hyperkalemia. If the pt is stable, begin with Ca++ & bicarb. Consider albuterol. Serial 12-leads. Start toward PCI capable facility. If it is hyperkalemia, initial treatment should begin to improve pt's condition and there is no harm caused from the increased transport time. If there is an underlying MI as well,…
