A CT Coronaryangiogram was ordered. Here are the results: --Minimally obstructive coronary artery disease. --LAD No signs for aortic dissection or pulmonary embolus. --"Results were discussed with the ordering physician. Thus, Wellens' syndrome should be thought of as a transient OMI or transient STEMI.
The Queen of Hearts disagrees, diagnosing OMI with high confidence: Case Continued: The EKG was not immediately recognized by the emergency provider, who ordered a CT scan to rule out aortic dissection at 1419. Most STEMI have peak troponin I over 1000 ng/L and most NSTEMI below that level.
As his pain was very severe, emergency physicians concerned of aortic dissection and ordered a thoracic CT scan. Coronary arteries cannot be assessed because the scan was not gated, but proximal segments of the coronary arteries seem to be open with some contrast. Here is the post-intervention angiogram and post-PCI ECG.
This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? Incidence of an acute coronary occlusion.
Look at the aortic outflow tract. Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. The diagnostic coronaryangiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve.
There is ventricular hypertrophy in the absence of abnormal loading conditions, such as aortic stenosis, or hypertension, for example – of which the most common variant is Asymmetric Septal Hypertrophy. This worried the crew of potential acute coronary syndrome and STEMI was activated pre-hospital.
50% of LAD STEMIs do not have reciprocal findings in inferior leads, and many LAD OMIs instead have STE and/or HATWs in inferior leads instead. The ECG easily meets STEMI criteria in all leads V2-V6, as well. CT angiogram chest: no aortic dissection or pulmonary embolism. 24 yo woman with chest pain: Is this STEMI?
She had this ECG recorded: Obvious massive anterior STEMI She was quickly brought to the critical care area and the cath lab was activated. Here is the ECG at 25 minutes: Terrible LAD STEMI (+) OMI So a CT scan was done which of course showed a normal aorta. This time the Queen of Hearts interpreted: No STEMI or Equivalent.
Supply-demand mismatch can cause ST Elevation (Type 2 STEMI). Also see these posts of Type II STEMI. An EKG from a year prior was available for comparison: The ED physician noted Initial EKG here read by the computer as a STEMI, however, there is a very poor baseline and a lot of artifact.
