Abnormal vital signs are poor predictors of mortality associated with pulmonary embolism (PE).  Diagnosis of PE and right ventricular (RV) strain with transthoracic echocardiography (TTE) however, has been well documented as a predictor for pending shock and significant in-hospital mortality.  One study done by Grifoni S et al, showed that 10% of normotensive patients with PE and RV strain on echo developed PE related shock, and 3% died, whereas normotensive patients without signs of RV strain remained hemodynamically stable.
