The commonest causes of MINOCA include: atherosclerotic causes such as plaque rupture or erosion with spontaneous thrombolysis, and non-atherosclerotic causes such as coronary vasospasm (sometimes called variant angina or Prinzmetal's angina), coronary embolism or thrombosis, possibly microvascular dysfunction.

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?

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.’

The HEART and EDACS scores are helpful to risk stratify patients with chest pain, but they hinge on accurate ECG interpretation: a low score doesn’t apply if the ECG shows STEMI(+)OMI, and shouldn’t be used for STEMI(-)OMI or OMI reperfusion either 2.

Using person-linked hospitalisation data, we compared International Classification of Diseases (ICD)-coded data with biomarker-classified admission rates for ST-segment elevation MI (STEMI), non-STEMI (NSTEMI) and unstable angina (UA) in Western Australia (WA). Results There were 37 272 ACS admissions in 30 683 patients (64.2%

50% of LAD STEMI have Q-waves by one hour. Smith : In limb leads, the ST vector is towards lead II (STE lead II STE lead III, which is more likely with pericarditis than with STEMI). This correlates with potentially salvageable myocardium. See Raitt et al.: These findings together are more commonly seen with pericarditis. Hammill, S.
