Right atrium contractility and right ventricular diastolic function assessed by pulsed Tissue Doppler Imaging can predict brain natriuretic peptide in adults with acquired pulmonary hypertension

Serum BNP correlates with RA contractility and RV diastolic dysfunction by RV TDI in adults with acquired PH. Increased BNP may be related to decreased RA systolic function and RV diastolic function in these patients.
