Echocardiography-led multimodal assessment for pulmonary hypertension in a right heart catheterization-referred cohort: incremental value of ECG and natriuretic peptides.
Background Right heart catheterization (RHC) is the reference standard for diagnosing pulmonary hypertension (PH), whereas echocardiography is the primary noninvasive tool for identifying patients who require further evaluation. Whether electrocardiography (ECG) and natriuretic peptides provide incremental diagnostic information beyond echocardiographic assessment in patients referred for RHC remains uncertain. Methods This single-center retrospective study included 130 hospitalized patients...
