critical actions of Pulmonary Embolism Severity Index PESI

  • The PESI is only meant for risk stratification of pulmonary embolism after the diagnosis has been made.
  • Findings which could point toward clinically significant PE should not be overlooked in the setting of a low PESI score.
  • Additional pathology which could lead to morbidity or mortality should not be overlooked in the setting of a low PESI score.
  • All results for the validation of the PESI were made with patients who were treated for PE initially with enoxaparin, and then encouraged to transition to vitamin K antagonists.
