Purpose The simple right ventricular contraction pressure index (sRVCPI) is a new echocardiographic variable for estimating the right ventricular systolic function. Our aim was to investigate the association between the sRVCPI, the pulmonary embolism severity index (PESI), and mortality rate in acute pulmonary embolism (APE). Methods We included in this study 116 patients diagnosed with APE by pulmonary computed tomography angiography or ventilation/perfusion scintigraphy. They were divided into two groups based on the simplified PESI < or >1. Tricuspid regurgitation velocity and TAPSE were measured and used for sRVCPI calculation. Results Mortality was higher in patients with a higher sRVCPI (P < .001). In receiver operating characteristic (ROC) curve analysis using a cut-off level of 312.8 mm Hg mm, sRVCPI predicted mortality with a sensitivity of 86.8% and specificity of 69.5% (ROC area under curve: 0.712; 95%CI 0.597-0.882; P < .001). The sRVCPI was lower in the sPESI >1 than in the sPESI <1 group (364.3 +/- 31.9 vs 511.6 +/- 26.1; P < .001). There was an inverse correlation between sRVCPI and the sPESI score (-0.784; P < .001). Conclusion The sRVCPI correlated with the sPESI score and was associated with mortality in patients with APE. This easily measurable variable may be used to predict short-term mortality in APE patients.

Introduction Acute pulmonary embolism (APE) is a cardiothoracic thromboembolic emergency at risk of life-threatening. Several risk graduation algorithms may be applied to delineate short-term mortality in patients with APE. In this study, we aim to depict the relationship between the right ventricular early inflow-outflow (RVEIO) index, which is a Doppler-based parameter, and the pulmonary embolism severity index(PESI) in acute pulmonary embolism. Methods In the presented study, a total of 160 patients who were diagnosed with APE using pulmonary computed tomography angiography or ventilation/perfusion scintigraphy were comprised. Patients were separated to 2 groups based on the simplified PESI (sPESI): sPESI < 1 (n = 88) and sPESI >= 1 (n = 72). Echocardiographic parameters, including the RVEIO index, were measured. Results There were no significant differences between the groups in age and gender distribution, or the presence of diabetes mellitus, hypertension, smoking, and history of coronary artery disease. There was a positive correlation with the mortality rate and RVEIO index; the mortality was higher in patients with a higher RVEIO index(<0.001). In receiver operating characteristic (ROC) curve analysis using a cutoff level of 14.39, RVEIO index predicted mortality with a sensitivity of 80.4% and specificity of 57.6%(ROC area under curve:0.694; 95%CI, 0.581-0.814; P < .001). RVEIO index was higher in the sPESI >= 1(n:72) than in the patients with sPESI < 1(14.27 +/- 2.13 vs 10.63 +/- 2.09; P < .001). There was a positive correlation between RVEIO index and sPESI score(+0.428; P < .001). Conclusion As well as predicting the degree of tricuspid regurgitation (TR), the RVEIO index is well-correlated with sPESI score and is associated with mortality in patients with APE. This easily measurable parameter may be used to predict short-term mortality in APE patients.
