Abstract

OBJECTIVE:

To determine the prognostic value of transthoracic echocardiography in hemodynamically stable patients diagnosed with acute symptomatic pulmonary embolism.

PATIENTS AND METHODS:

Hemodynamically stable outpatients diagnosed with acute symptomatic pulmonary embolism at a tertiary university hospital were prospectively included in the study. All patients underwent transthoracic echocardiography within 48 hours of diagnosis. The primary endpoint was all-cause mortality at 1 month.

RESULTS:

Right ventricular dysfunction was documented by echocardiography in 86 of the 214 patients (40%) in our series. In the first month of follow-up, 7 patients died--4 with positive echocardiographic findings and 3 with negative findings (odds ratio, 2.0; 95% confidence interval, 0.4-9.3; P=.41). For the primary endpoint, the negative predictive value of transthoracic echocardiography was 98%, the positive predictive value was 5%, and the negative likelihood ratio was 0.7. The negative predictive value was 100% and the positive predictive value was 3% when we analyzed death due to pulmonary embolism only.

CONCLUSIONS:

In our setting, transthoracic echocardiography is not useful for prognostic stratification of hemodynamically stable patients with pulmonary embolism.
