Objective To explore the clinical application value of right ventricular (RV) myocardial global longitudinal strain(RVGLS) in assessing changes in RV function in patients with pulmonary embolism.Material and methods Patients with pulmonary embolism who were treated successfully in our hospital from January 2022 toDecember 2023 were enrolled in this study. Included were 34 pulmonary embolism patients without pulmonary hypertension (Group B), 31 with pulmonary hypertension (Group C), and 35 healthy volunteers, matched by gender and age (Group A). Clinical data and RV function-related variables of these groups were compared.Results Compared with pre-treatment values of Group A, the following variables of Groups B and C had higher pre-treatment values (p 20.59 % is the best cutoff value for predicting the occurrence of pulmonary embolism, and RVGLS> -17.42 % is the best cutoff value for predicting the occurrence of pulmonary hypertension in patients withpulmonary embolism. The results of multivariable logistic regression model analysis showed that RVGLS>-20.59 % is independently related to the occurrence of pulmonary embolism, and RVGLS>-17.42 % is independently related to pulmonary embolism complicated by pulmonary hypertension (p-20.59 % is independently related to pulmonary embolism, and there is a significant correlation between RVGLS and RVVFAC, RVEF, RIMP, and PASP in patients with pulmonary embolism before and after treatment.
