Abstract:Objective To study the clinical value of color Doppler echocardiography(CDE)in the diagnosis of cor pulmonale(CPM).Methods A total 70 patients with CPM who treated and accepted CDE examination in People′s Hospital of Lianshan District in Huludao City from December 2018 to December 2019 were selected as the study group,and 70 healthy physical examinees who underwent CDE during the same period were selected as the control group.The echocardiographic indexes and the pulmonary arterial hypertension of the two groups were compared.Results The myocardial systolic peak longitudinal strain(SL),left ventricular mass(LVM),left atrial volume(LAV),right ventricular anterior wall(RVAW),right ventricular(RV),right atrium(RA)and main pulmonary artery diameter(MPAD)of the study group were higher than those of the control group,the myocardial systolic peak radial strain(SR)and left ventricular ejection fraction(LVEF)were lower than those of the control group,and the differences were statistically significant(P<0.05).The systolic blood pressure,diastolic blood pressure and mean pressure of pulmonary artery in the study group were(85.45±15.28),(42.64±9.59)and(70.84±9.44)mmHg.Among the 70 cases included in the study group,60 cases were diagnosed,accounting for 85.71% and 10 cases were not diagnosed,accounting for 14.29%.Conclusion CDE can accurately estimate the pulmonary arterial hypertension in patients with CPM,and has a high clinical value in the diagnosis of CPM.
