ABSTRACT

Objective To determine the si gnificance of plasma level of B-type natriuretic peptide (BNP) in patients with congestive heart failure (CHF) for differential diagnosis of their acute dyspne aMethods Totally, 130 patients with acute dyspnea were selected, including 78 patients diagnosed as CHF with left ventricular ejection fraction less than 040 and 52 patients without CHF Plasma level of BNP was m easured by a rapid, point-of-care quantitative immunofluorescent assay Results Plasma level of BNP was(732?53)ng/L in patients wit h CHF, much higher than that in those without CHF(71?34)ng/L(P
