NSTEMI mimics

"Summary
  • Type 1 NSTEMI involves a new, partial occlusion of the cardiac vessel. Type 2 NSTEMI involves a supply-demand deficiency.
  • Always check for reciprocal ST-segment elevation when observing ST-segment depression.
  • Posterior MI diagnosis requires ST-segment elevation of 0.5mm or greater.
  • Upsloping ST-segment depressions with tall T-waves through V1-V6 is a STEMI equivalent.
  • The American Heart Association recognizes aVR ST-segment elevation in the setting of anterolateral ST-segment depression as an indication for emergent cardiac catheterization.
  • PE and dissection are important mimics of NSTEMI.
  • Consider inflammatory markers in suspected cases of myocarditis and pericarditis.
  • Differentiation of NSTEMI-mimics that involve a physiologic increase in post-left/right ventricular afterload (HOCM, AI, AS, PAH, COPD) can generally be made by careful examination of the patient’s medical history and clinical presentation."
