OBJECTIVE Analysis of the characteristics of right ventricular remodeling has important clinical value for early prediction of mortality in patients with chronic pulmonary embolism.This study aims to observe and evaluate the characteristics of echocardiography in the right ventricle reconstruction of patients with chronic pulmonary embolism.METHODS Totally 40 patients with chronic pulmonary embolism admitted in our hospital from May,12018 to May,12019 were selected as the case group and 40 healthy people who have undergone physical examination in our hospital were regarded as the control group.Doppler echocardiography was performed in both groups.The conditions of each path of right ventricle,the basic situation of right ventricular function,and the right ventricular Tei index were compared between the two groups.RESULTS The right ventricular(RV)in the control group was(27.63±3.71)mm,which was lower than the(41.13±3.86)mm in the case group,t=15.948,P<0.001.The right atrium(RA)was(32.25±3.09)mm,lower than(43.52±3.32)mm in the case group,t=15.716,P<0.001.The main pulmonary artery(MPA)was(20.32±2.53)mm,lower than the case group’s(30.54±2.97)mm,t=16.567,P<0.001.The systolic pulmonary artery pressure(SPAP)of the control group was(32.63±7.72)mm Hg,which was lower than that of the case group’s(58.07±7.64)mm Hg,t=14.814,P<0.001.Right ventricular end-diastolic volume end-diastolic volume(RVEDV)was(63.51±18.06)ml,which was lower than the case group’s(72.54±19.03)ml,t=2.177,P=0.033.Right ventricular end-systolic volume(RVESV)was(29.34±12.73)ml,lower than(48.15±13.62)ml in the case group,t=6.381,P<0.001.Right ventricular ejection fraction(RVEF)was(54.31±12.42)%,high In the case group’s(44.82±14.03)%,t=3.203,P=0.002.The right ventricular Tei index of the control group was(0.53±0.02),which was higher than the case group’s(0.31±0.03),t=38.591,P<0.001.The ICT+IRT index was(125.09±14.83)ms,which was lower than that of the case group’s(295.41±15.21)ms,t=50.708,P<0.001.ET value was(287.97±18.63)ms,which was higher than the case group’s(225.09±21.43)ms,t=14.005,P<0.001.CONCLUSIONS Echocardiography can directly measure the right ventricle and main pulmonary artery in patients with chronic pulmonary embolism.It can effectively evaluate the size,shape and pressure of the right ventricle,which is beneficial to the right ventricular remodeling.
