Utility of tests in assessing acute PE

Test	Value
Brain natriuretic peptide	Elevated levels associated with short-term mortality in hemodynamically stable patients with acute PE [22, 23]
Troponin	Elevated levels associated with greater in-hospital and short-term mortality in patients with acute PE [30, 31]
Electrocardiogram	Abnormalities associated with acute PE (nonspecific) [9, 24] and greater risk of death in patients with acute PE [25, 28]
