We sought to determine the contemporary utilization of early TTE (within 72 hours of PE diagnosis) and explored the association between TTE findings and PE -related mortality. Methods and Results Data from the RIETE (Registro Informatizado Enfermedad TromboEmbolica) registry, a multicenter registry of consecutive patients with acute PE , were used (2001-July 2017). We used a generalized linear mixed model to determine predictors of early TTE performance. Moreover, the association between 3 TTE variables (right atrial enlargement, right ventricular hypokinesis, and presence of right heart thrombi) and 30-day PE -related mortality was assessed in generalized linear mixed models adjusted for PE severity index, and other comorbidities. Among 35 935 enrollees with acute PE , 15 375 (42.8%) underwent early TTE . There was an increase in early TTE utilization rate over time ( P YR 2018 FD 2018 LK http://hdl.handle.net/10668/13139 UL http://hdl.handle.net/10668/13139 LA en DS RISalud RD Apr 19, 2025
