COPD is a leading cause of mortality. ⋯ An MLMP-COPD model outperformed four existing models for predicting all-cause mortality across two COPD cohorts. Performance of machine learning was similar to that of traditional statistical methods. The model is available online at: https://cdnm.shinyapps.io/cgmortalityapp/.

There remains uncertainty in the optimal prognostication and management of patients with intermediate-risk pulmonary embolism (PE). Transthoracic echocardiography can identify right ventricular dysfunction to recognize intermediate-high-risk patients. ⋯ Low SVI was associated with in-hospital death or cardiopulmonary decompensation in acute PE. SVI had excellent performance compared with other clinical and echocardiographic variables.
