To elucidate whether the expression of miR-29a-3p and THBS2 may be functional predictors of RV function prognosis and PAH outcome, echocardiographic parameter (TAPSE) and Swan-Ganz parameters (mPAP and pulmonary vascular resistance (PVR)) were used for analysis. Here, THBS2 is linked to pulmonary arterial hypertension.
