Pneumonia and acute exacerbations of obstructive lung diseases (AEOLD) are associated with a significant long-term mortality. Elevated level of amino-terminal pro B-type natriuretic peptide (NT-proBNP) is a predictor of late all-cause mortality in these disorders but the pathophysiological basis for this is unknown. The present study was conducted to define the predictive role of NT-proBNP on late cardiovascular mortality among patients with acute lung disorders. ⋯ NT-proBNP concentration during pneumonia or AEOLD was strongly associated with late cardiovascular mortality but not with non-cardiovascular mortality. The results suggest that the increase in NT-proBNP during acute lung disorders may reveal occult cardiac diseases arousing a question whether patients with acute pulmonary disorders with elevated NT-proBNP levels should be subjected to further diagnostic or therapeutic cardiovascular interventions.
