[Predictors of adverse outcomes in patients with chronic obstructive pulmonary disease and pulmonary embolism and the predictive value of the simplified pulmonary embolism severity index].

To explore the relevant factors associated with poor prognosis in patients suffering from chronic obstructive pulmonary disease (COPD) combined with pulmonary embolism (PE), and investigate the predictive value of the simplified pulmonary embolism severity index (sPESI) score on adverse outcomes in these patients.
