Educational Pearls

  • Not every troponin elevation is an MI.
  • Trop elevates in about an hour in ACS and stays elevated for days.
  • Non-MI conditions that cause elevated troponin: Critical illness (sepsis), increased cardiac demand, right heart strain, LV dysfunction, hypotension, pressor use, acute PE, SAH, chronic renal failure, CHF, aortic dissection, and peri/myocarditis.
  • Elevated troponin in settings other than MI is correlated with increased mortality.
