          Abstract

          The association of raised levels of natriuretic peptides with elevated risk of mortality was investigated in the present analysis of the Membrane Permeability Outcome study.

            B-type natriuretic peptide in cardiovascular disease.

            Natriuretic peptide hormones, a family of vasoactive peptides with many favourable physiological properties, have emerged as important candidates for development of diagnostic tools and therapeutic agents in cardiovascular disease. The rapid incorporation into clinical practice of bioassays to measure natriuretic peptide concentrations, and drugs that augment the biological actions of this system, show the potential for translational research to improve patient care. Here, we focus on the physiology of the natriuretic peptide system, measurement of circulating concentrations of B-type natriuretic peptide (BNP) and the N-terminal fragment of its prohormone (N-terminal BNP) to diagnose heart failure and left ventricular dysfunction, measurement of BNP and N-terminal BNP to assess prognosis in patients with cardiac abnormalities, and use of recombinant human BNP (nesiritide) and vasopeptidase inhibitors to treat heart failure.

              Plasma brain natriuretic peptide concentration: impact of age and gender.

              We wished to examine the effects of age and gender on plasma brain natriuretic peptide (BNP) concentration in a population-based study. Measurement of BNP concentration is approved for use in the diagnosis of heart failure and may aid in the detection of left ventricular dysfunction. Although BNP is approved for clinical use, there are few data regarding the range of BNP observed in persons without cardiovascular disease or cardiac dysfunction. These data are essential for the interpretation of BNP. In 2,042 randomly selected residents of Olmsted County, Minnesota, >44 years old, BNP (Shionogi and Biosite assays), Doppler echocardiography, and medical record review were performed. A normal subset of subjects (n = 767) in sinus rhythm without cardiovascular, renal, or pulmonary disease or diabetes; on no cardiovascular medications; and with normal systolic, diastolic, and valvular function was identified. Within the normal subset, the distribution of BNP differed by age, gender, and assay system. With both assays, BNP increased significantly with age and was significantly higher in women than men, leading to age-, gender-, and assay-specific reference ranges. Receiver operating characteristic analysis for the ability of BNP to detect an ejection fraction < or = 40% was performed in each age/gender stratum in the entire cohort (n = 2,042) and confirmed that discriminatory values for BNP for detection of reduced ejection fraction were higher in women and older persons and were different between the two assays. Interpretation of BNP should include consideration of age-, gender-, and assay-specific partition values.
