Higher oxygen saturation at presentation was significantly associated with a lower risk of mortality from acute pulmonary embolism within 3 months (adjusted OR 0.21).
Cohort (n=81)
No
Low systolic blood pressure, high pulse rate, and low oxygen saturation at presentation are key clinical indicators associated with 3-month mortality in patients with acute pulmonary embolism.

Abstract Background Acute pulmonary embolism (APE) is under diagnosed and may be fatal. Computed tomographic pulmonary angiography (CTPA) showing right ventricular failure is associated with mortality in APE. In resource-limited facilities, clinical factors are crucial. Objectives We studied clinical factors that were associated with death from APE. Methods We enrolled patients with APE proven by CTPA between January 1, 2007 and July 31, 2011 at Khon Kaen University. Clinical factors associated with death from APE were studied by multiple logistic regression analysis. An online tool to assess risk of death from APE was also used. Results There were 81 eligible patients in the study. Of those, 20 patients (25%) died within 3 months. Clinical factors significantly associated with death were low systolic blood pressure (SBP), high pulse rate, and low oxygen saturation at presentation. Conclusions Initial systolic blood pressure, pulse rate, and oxygen saturation are associated with mortality from APE.
Makarawate et al. (Fri,) conducted a cohort in Acute pulmonary embolism (n=81). Oxygen saturation was evaluated on Mortality within 3 months (adjusted OR 0.21, 95% CI 0.06-0.78, p=<0.05). Higher oxygen saturation at presentation was significantly associated with a lower risk of mortality from acute pulmonary embolism within 3 months (adjusted OR 0.21).
