Clinical Trial[Usefulness of B-type natriuretic peptide (BNP) for the diagnosis of new-onset heart failure with a preserved left ventricular systolic function in longstanding hypertensive patients with acute dyspnea].
B-type natriuretic peptide (BNP) has been largely validated in the etiologic diagnosis of acute dyspnea. Nevertheless, its reliability in the setting of a preserved left ventricular systolic function (ejection fraction >50%) has not been adequately established. ⋯ BNP is a reliable biomarker of new-onset heart failure with a preserved systolic function in hypertensive patients, in particular older, hospitalized for acute dyspnea and can be safely integrated in the diagnostic strategy.
