TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The detection of pulmonary hypertension in patients with chronic lung disease has prognostic implications. The brain natriuretic peptide (BNP) has been suggested as a noninvasive marker for the presence and severity of pulmonary hypertension.', 'We evaluated circulating BNP levels as a parameter for the presence and severity of pulmonary hypertension in patients with chronic lung disease.', 'BNP levels were measured in 176 consecutive patients with various pulmonary diseases. Right heart catheterization, lung functional testing, and a 6-min walk test were performed. The mean follow-up time was nearly 1 yr.', 'Significant pulmonary hypertension (mean pulmonary artery pressure > 35 mm Hg) was diagnosed in more than one-fourth of patients and led to decreased exercise tolerance and life expectancy. Elevated BNP concentrations identified significant pulmonary hypertension with a sensitivity of 0.85 and specificity of 0.88 and predicted mortality. Moreover, BNP served as a risk factor of death independent of lung functional impairment or hypoxemia in uni- and multivariate analysis.'] Is brain natriuretic peptide a prognostic parameter in chronic lung disease?
