OBJECTIVE: To explore the clinical value of echocardiography in the assessment of left ventricular diastolic function in patients with acute pulmonary embolism (APE). METHODS: APE patients in our hospital from June 2019 to June 2021 were selected as the observation group. They were divided into low-risk group (19 cases), medium-risk group (16 cases) and high-risk group (15 cases). The non-APE people in our hospital during the same period were selected as the control group. All subjects underwent echocardiography to observe the performance of APE patients under echocardiography. The peak velocity ratio S-wave/D-wave (S/D), early diastolic annular velocity/advanced diastolic annular velocity (Ea/Aa), early filling/early diastolic annular velocity (E/Ea), and early filling/early diastolic annular velocity (E/Ea) were compared with Ar and Vp, respectively; receiver operator characteristic (ROC) curve was used to evaluate the value of echocardiography in evaluating left ventricular diastolic function in patients with APE. RESULTS: Echocardiography show different manifestations of APE patients. Compared with the control group, S/D, Ea/Aa, and Vp in the observation group were significantly decreased and E/Ea and Ar in the observation group were significantly increased (p < 0.05). With the increase of risk stratification, S/D, Ea/Aa, and Vp gradually decreased, E/Ea and Ar gradually increased, and the difference was statistically significant (p < 0.05). The sensitivity, specificity, accuracy, positive predictive value, negative predictive value, area under curve (AUC), and 95% CI were 89.52%, 65.57%, 72.86%, 80.82%, 75.38%, 0.730, and 0.629-0.831, respectively. CONCLUSION: Echocardiography can effectively evaluate left ventricular diastolic function in patients with APE, and there are significant differences in left ventricular diastolic function in different risk stratification, which has important reference value for clinical diagnosis and treatment of APE.
