Prosperi-Porta G, Solverson K, Fine N, et al. - Researchers investigated the association of echocardiographic-derived stroke volume index (SVI) with death or cardiopulmonary decompensation in intermediate-risk patients with pulmonary embolism (PE). Echocardiographic-derived variables including SVI were retrospectively evaluated in normotensive patients with acute PE who were admitted between January 2012 and March 2017. They used the Doppler velocity-time integral in the left or right ventricular outflow tract to determine SVI. In-hospital PE-related death or cardiopulmonary decompensation was reported in 26 of the 665 intermediate-risk patients (3.9%) with PE. Findings revealed correlation of low SVI with in-hospital death or cardiopulmonary decompensation in acute PE. Relative to other clinical and echocardiographic variables, SVI had excellent performance.
