Abstract:
Objective To investigate the application of the Doppler echocardiography on the clinical value on the left ventricular myocardial remodel and dysfunction in neonates with hypoxia-induced pulmonary artery hypertension. Methods The Doppler echocardiography (ECHO) datas of 24 neonates of pulmonary diseases with secondary pulmonary artery hypertension were identified by color Doppler echocardiography,and compared with 14 neonates with pulmonary diseases without pulmonary artery hypertension. Results Pulmonary artery systolic pressrure (PASP) (38.23?3.26) mm Hg increased ,the diameter of right ventricular(11.92?2.18)mm vs (7.34?0.93) mm and pulmonary artery(10.20?1.21)mm vs (6.89?0.22) mm and diameter of left ventricular end-diastolic(19.74?0.71)mm vs (14.42?0.32) mm in PAH groups increased significantly ( P 0.05). There was positive correlation between the increased pulmonary artery pressure in pulmonary artery hypertension groups and the AV/EV of the mitral value orifice blood stream ( r=0.4126,P
