Prosperi-Porta G, Solverson K, Fine N, et al. - This retrospective study was planned to determine whether echocardiographic-derived stroke volume index (SVI) related to mortality or cardiopulmonary decompensation among intermediate-risk patients suffering from pulmonary embolism (PE). In normotensive patients who encountered acute PE and got admitted between January 2012 and March 2017, echocardiographic-derived variables that included SVI were assessed. By using Doppler velocity-time integral in the left or right ventricular outflow tract, SVI was ascertained. Findings revealed a correlation of low SVI with in-hospital death or cardiopulmonary decompensation in acute PE. Relative to other clinical as well as echocardiographic variables, SVI demonstrated excellent performance.
