Echocardiography Doppler in pulmonary embolism: Right ventricular dysfunction as a predictor of mortality rate

To test the hypothesis that right ventricular (RV) systolic dysfunction at the time of diagnosis of pulmonary embolism (PE) is a predictor of mortality rate, 126 consecutive patients with PE were examined with echocardiography Doppler (ED) on the day of diagnosis. RV function was assessed by evaluation of wall motion on a four-point scale. The material was divided into two groups: group A ( n = 56) with normal or slightly reduced RV function and group B ( n = 70) with moderately or severely reduced RV function. The overall mortality rate was 7.9% in the hospital and 15.1% within 1 year. Four deaths occurred in group A and 15 in group B ( p = 0.04). All in-hospital deaths ( n = 10) occurred in group B ( p = 0.002). The variables associated with mortality rate were RV dysfunction and cancer (in-hospital, p = 0.002 and 0.004; 1 year, p = 0.04 and
