Abstract 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 < 0.001, respectively). Nine (7.1\%) deaths (all in-hospital) were caused by PE. Five of these patients had advanced-stage cancer. The in-hospital mortality rate in patients without cancer was 4\%, all from PE and all in group B. In conclusion, RV dysfunction when diagnosis of PE is established is associated with mortality rate. A strategy for risk stratification of patients with PE with ED may be of clinical usefulness.
