摘要: The precise mechanism explaining the increased N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations among patients with concomitant acute heart failure (AHF) and kidney dysfunction is not fully understood. aim of this study was to assess impact on simultaneous measures plasma urinary NT-proBNP in an unselected cohort AHF. One hundred thirty-eight consecutive hospitalized (median age: 74 years; interquartile range: 67-80 54% male) a diagnosis AHF were prospectively studied. Blood urine samples collected hospital arrival determine concentrations. Both declining estimated glomerular filtration rate (eGFR; P<.001 for both). However, after multivariate adjustment, eGFR found be independent predictor (but urinary) concentration (eGFR: β=-0.19; P=.016). Indeed, main determinant its (β=0.42; P<.001), ratio urine/plasma function similar across range examined (P=.368). In dysfunction, circulating may mainly related cardiac secretion decreased renal clearance.
