Objective To investigate the value of echocardiography for assessing the right ventricular function before and after treatment in the patients with pulmonary embolism.Methods Ninety-six patients with pulmonary embolism in our hospital from June 2014 to December 2015 were selected as the research subjects and divided into low-risk group,intermediate-risk group and high-risk group according to the disease severity.The echocardiographic examination was performed before and after treatment in all cases.Results The pulmonary artery systolic pressure after treatment in the low-risk group was lower than that before treatment(P0.05).The transverse diameter of right ventricle,transverse diameter of right ventricle and pulmonary artery systolic pressure after treatment in the intermediate-risk group and high-risk group were lower than those before treatment(P0.05).The Tei index after treatment in the low-risk group,intermediate-risk group and high-risk group was lower than that before treatment(P0.05).The right ventricle ejection fraction(RVEF),right ventricular end-systolic volume(RVESV)and right ventricular end-diastolic volume(RVEDV)in the low-risk group had no statistically significant difference between before and after treatment.RVEF after treatment in the intermediate-risk group and high-risk group was higher than that before treatment(P0.05),while RVESV and RVEDV after treatment were lower than those before treatment(P0.05).Conclusion Echocardiography can objectively reflect the change situation of right heart function before and after treatment in the patients with pulmonary embolism,and can be used as an evaluation method for the effect of pulmonary embolism treatment.
