Abstract:
were measured at the end of inspiratory.ResultsThe differences of following parameters were statistically significant between the healthy control group, mild PH group, moderate PH group and severe PH group: velocity time integral of ventricular systolic wave (SVTI), velocity time integral of ventricular diastolic wave (DVTI), AR, AR/S, ARVTI/SVTI, AR/(S+D), ARVTI/(SVTI+DVTI,F=2.940, 2.838, 3.373, 7.681, 3.478, 12.052, 4.806;P<0.05,<0.05,<0.05,<0.01,<0.05,<0.01,<0.01). Correlation analysis showed that ratio of AR/(S+D) was positively correlated with pulmonary artery mean pressure (r= 0.575,P<0.01). ConclusionsThe ratio of AR/(S+D) of MHV Doppler flow spectra was correlated with pulmonary artery mean pressure. The ratio increased along with the increasing of pulmonary pressure in CHD patient. The Doppler echocardiographic detection of MHV flow had a certain reference value for the diagnosis of PH. The ratio of AR/(S+D) could be a new non-invasive parameter for evaluating PH.
