Abstract：Objective To evaluate right ventricular functional assessment of the effectiveness of application
of Real Time Three-Dimensional Echocardiography (RT-3DE) in diagnosis of patients sufered Pulmonary
Hypertension (PAH) along with Systemic Lupus Erythematosus (SLE). Methods A total of 54 patients with
PAH and SLE were treated in the hospital between March 2015 to February 2016 (Observation Group), 54
healthy volunteers in the hospital were selected as the study group during the same period. According to the
degree of PAH, the Observation Group were divided into mild group (pulmonary artery systolic pressure
between 35～50 mmHg, 30 cases) and severe group (systolic pulmonary artery pressure>50 mmHg, 24 cases).
Comparative analysis of Right Ventricular End-Systolic Volume (RVESV), End-Diastolic Volume (RVEDV),
Stroke Volume (SV), Ejection Fraction (RVEF), End-Diastolic Area (RVEDA), End-Systolic Area (RVESA),Systolic Stage Area (RAA), the rate of area change (FAC), Right Ventricular and Left Ventricular enddiastolic
inner diameter ratio (RV/LV), tricuspid inflow velocities (E, A), annulus motion haste (s’, e’, a’), right
ventricular myocardial performance index (MPI) and systolic pulmonary artery pressure among groups.
Results Compared with Control Group, mild group and severe group showed obviously increasing right
ventricle RVEDV, RVEF and RVESV values with significant differences (t=7.896; 8.039; 9.031, P<0.05),
no statistically significant differences in SV (P>0.05); compared with mild group, severe group showed
obviously increasing right ventricle RVEDV, RVEF and RVESV values with significant differences
(t=8.534; 8.127; 9.542, P<0.05), there is no statistically significant differences in SV (P>0.05); compared
with each groups, age (t=-1.237; 0.145), systolic blood pressure (t=1.543; 0.761), diastolic blood pressure
(t= 2.013; 0.308 ) and body mass index (t=-1.779; 1.381) without statistically significant differences
(P>0.05); the heart rate between severe group and other groups with statistically significant differences
(t=7.893; 1.608, P<0.05); compared with Control Group, mild group and severe group showed obviously
increasing RV/LV, RAA, RVESA, E/e’, MPI (t=3.896; 3.039; 4.031; 4.332; 3.733, P<0.05), FAC, s’ and
e’ significantly decreased (t=3.824; 3.918, P<0.05); while mild group compared with severe group, sPAP,
RAA, RVESA, E/e’, MPI and s’ with statistically significant differences (t=4.731; 4.057; 3.938; 3.682;
3.781; 4.375, P<0.05). Conclusion The RT-3DE can evaluate the right ventricular volume and function
of patients accurately and help the clinician to obtain more accurate information, which provides a great
convenience for therapeutic schedule. Therefore, it is worthy of further promotion in clinical use.
