Abstract Objective: To study the clinical significance of ultrasonic cardiogram in evaluating right heart function in patients with acute or chronic pulmonary embolism (PE). Methods: 96 patients with PE in our hospital from October 2017 to October 2019 were selected for the study. Among them were 52 cases of acute pulmonary embolism (APE) and 44 cases of chronic pulmonary embolism (CPE). Another 50 cases of healthy examiners in our hospital at the same period were selected as control group. The two-dimensional ultrasound, tissue Doppler imaging (TDI) were performed, and the right ventricular anterior wall thickness (RVAWTd), right ventricular transverse diameter (RV), right atrial transverse diameter (RA), main pulmonary artery diameter (MPA), right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV), stroke volume (RVSV), right ventricular ejection fraction (RVEF), and right ventricular Tei index were compared and analyzed. Results: The RVAWTd, RV and RA in APE group were significantly higher than those in control group (P>0.05). The RVAWTd, RV and RA in CPE group were higher than those in APE group and control group (P<0.05). The RVEDV, RVESV and PASP in APE group were higher than those in control group, and the RVSV and RVEF were lower than those in control group, and the RVEDV, RVESV and PASP in CPE group were higher than those in APE group and control group, and the RVSV and RVEF were lower than those in APE group and control group (P<0.05). The ICT+IRT, ET and right ventricular Tei index in APE group were higher than those in control group, and the ICT+IRT, ET and right ventricular Tei index in CPE group were higher than those in APE group and control group (P<0.05). Conclusion: TDI and 2DE can accurately reflect the right ventricular systolic and diastolic function in patients with APE and CPE. Ultrasonic cardiogram evaluation of right heart function in PE patients can provide important reference information for clinical diagnosis and acute and chronic identification.
