Prosperi-Porta G, Solverson K, Fine N, et al. - Researchers investigated whether there exists a relation of echocardiographic-derived stroke volume index (SVI) with mortality or cardiopulmonary decompensation among intermediate-risk patients with pulmonary embolism (PE). A retrospective analysis was carried out among normotensive patients with acute PE who were admitted between January 2012 and March 2017, to assess echocardiographic-derived variables that included SVI. The Doppler velocity-time integral in the left or right ventricular outflow tract was used to ascertain SVI. Findings revealed an association of low SVI with in-hospital death or cardiopulmonary decompensation in acute PE. Excellent performance of SVI was also evident in comparison with other clinical and echocardiographic variables.
