title: Difficult cases in heart failure. Novel diagnostic markers in heart failure: an emerging paradigm shift?
abstract: The differential diagnosis of dyspnea can be overwhelming in the presence of competing diseases. The recent advent of the peptide marker brain natriuretic peptide has ushered in an era of refined diagnostic capability in heart failure. We present a clinical scenario to illustrate the usefulness of this new biomarker assay in directing appropriate therapy for heart failure. (c)2001 CHF, Inc.
