          In a study of 190 patients with acute pulmonary embolism, right ventricular dilation was present in 64 (34%), mean age 58 ± 15 years. The 18 electrocardiographic abnormalities on the 12-lead electrocardiogram had a sensitivity of 8–69%, a specificity of 70–98%, a positive predictive value of 23–69%, a negative predictive value of 64–83%, a likelihood ratio for a positive test of 1.3–4.4, and a likelihood ratio for a negative test of 0.41–1.10 in predicting right ventricular dilation in patients with acute pulmonary embolism.

          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 < 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.
