Hirai T, et al. - A retrospective analysis of all patients who underwent pharmacomechanical therapy (PMT) for massive or submassive pulmonary embolism (PE) at a single institution from 2010 to 2016 was conducted to ascertain whether the cardiac arrest triage (CART) Score would better predict poor outcomes after PMT for massive and submassive PE than traditional risk scores. According to the findings obtained, CART and electronic CART (eCART) scores better predict mortality in massive or submassive PE patients undergoing PMT compared to pulmonary embolism severity index (PESI) score.
