PURPOSE: This study aimed to evaluate hemodynamics and right ventricular function in patients with pulmonary hypertension (PH) using transthoracic echocardiography, and compare with measurements obtained using right heart catheterization (RHC).

METHODS: Seventy-five patients with PH were examined by both echocardiography and RHC. Echocardiography measurements included systolic pulmonary arterial pressure (SPAP), tricuspid annular plane systolic excursion (TAPSE). RHC measurements included systolic pulmonary arterial pressure (sPAP), mean pulmonary arterial pressure (mPAP), central venous pressure (CVP), and pulmonary vascular resistance (PVR). Patients were divided into two groups according to the difference between SPAP and sPAP: group I (overrated group) included group Ia and group Ib; group II (underrated group) included group IIa and group IIb.

RESULTS: SPAP was well correlated with sPAP (r=0.794, P<0.01). Among all echocardiographic measurements, only TAPSE was significantly different among groups Ia, Ib and IIa (P<0.05). In terms of RHC measurements, CVP differed significantly between groups Ia and IIb (P<0.05), while sPAP and mPAP revealed no significant differences among groups IIa, IIb and Ia (P<0.05).

CONCLUSIONS: Although SPAP measurements obtained using echocardiography is well correlated with sPAP measurements obtained using RHC, a high proportion of high or low estimation remains.

CLINICAL IMPLICATIONS: Our study found that SPAP measured using echocardiography is well correlated with sPAP measured using RHC, and only TAPSE and CVP were significantly different among PH patients with overrated or underrated SPAP by echocardiography. However, due to the small sample size of our study, further investigation is needed to determine the specific reasons of the overestimation or underestimation of measurement in SPSP by echocardiography.
