  1. Brain natriuretic peptide in an elderly population.

    Article - En anglais

    Objectives

    To study the relationship of brain natriuretic peptide concentrations to ageing, and whether brain natriuretic peptide could reflect current disease states in the general elderly population.

    Design

    Brain natriuretic peptide was measured in two population samples from the general population.

    Subjects

    Five hundred forty-five 85-year-old subjects from the longitudinal population study'70-year-old people in Gothenburg, Sweden'were investigated in respect to cardiovascular, renal and metabolic disease, and 191 subjects from the 40-year-old male population were examined.

    Main outcome measures

    To study the influence of ageing on circulating brain natriuretic peptide and the association between concentrations of brain natriuretic peptide and common disease states in the elderly.

    Results

    Brain natriuretic peptide concentrations were significantly increased in relation to ageing (P<0.001).

    Brain natriuretic peptide concentrations were significantly increased in elderly with congestive heart failure (P<0.001), ischaemic heart disease (P<0.001), atrial fibrillation (P<0.001) and renal dysfunction (P<0.001) but not in hypertension.

    In multivariate analysis, brain natriuretic peptide concentrations were predictive for ischaemic heart disease (P<0.001), atrial fibrillation (P<0.01), renal dysfunction (P<0.01), congestive heart failure (P<0.05) and treatment with bêta-adrenergic blockers (P<0.05). (...)
