Ability of echocardiography (ECHO)-estimated sPAPto predict the severity of PH determined with cardiac catheterization (CATH). PH was defined as estimated sPAP of >40 mm Hg in the presence of a measurable TRJV with echocardiography and as mPAP of >25 mm Hg during cardiac catheterization, mild/moderate PH was defined as PH with an estimated sPAP/sBP ratio of <0.67 with echocardiography and a mPAP/mean systemic arterial pressure ratio of <0.67 with cardiac catheterization, and severe PH was defined as PH with an estimated sPAP/sBP ratio of ≥0.67 with echocardiography and a mPAP/mean systemic arterial pressure ratio of ≥0.67 with cardiac catheterization.
