    Journal: Transplant Proc; 2009 Apr; 41(3):987-8. PubMed ID: 19376405.
    Abstract:
    BACKGROUND: The aim of this study was to assessed the correlation of N-terminal natriuretic peptide type B (NT-proBNP) with echocardiographic and hemodynamic indexes of right ventricular (RV) function and to evaluate the sensitivity and specificity of Doppler echocardiography in the diagnosis of portopulmonary hypertension. METHODS: All patients underwent liver transplantation for cirrhosis. We obtained clinical data, NT-proBNP levels, echocardiography, and right heart hemodynamic measurements before transplantation. RESULTS: Patients with pulmonary hypertension displayed significantly higher levels of NT-proBNP. They also showed higher model for End-stage Liver Disease scores and higher indices of RV overload on cardiac hemodynamics. The negative predictive value of echocardiography to identify pulmonary hypertension was 83%. A correlation was not observed between systolic pulmonary artery pressures measured by the two methods; however, NTproBNP showed a trend toward a significant correlation with mean pulmonary pressure as determined by hemodynamics (r = .3; P < .01). CONCLUSION: We concluded that NT-proBNP values showed significant correlations with pulmonary hypertension that could assist in a noninvasive diagnoseis for this group of patients.
