Abstract

Objectives This investigation evaluated the relationship between obesity and B-type natriuretic peptide (BNP) in heart failure.Background Obesity is a major risk factor for the development of heart failure, but the precise mechanisms remain uncertain. Physiologically, natriuretic peptides and lipolysis are closely linked.Methods A total of 318 patients with heart failure were evaluated between June 2001 and June 2002. Levels of BNP were compared in obese (body mass index [BMI] > or =30 kg/m(2)) and nonobese (BMI <30 kg/m(2)) patients with respect to New York Heart Association functional class and lean body weight-adjusted peak aerobic oxygen consumption. In a subset of 36 patients, plasma levels of tumor necrosis factor-alpha, interleukin-6, and soluble intercellular adhesion molecule-1 were measured.Results The population's BMI was 29.4 +/- 6.6 kg/m(2); 24% were lean (BMI <25 kg/m(2)), 31% overweight (BMI > or =25 to 29.9 kg/m(2)), and 45% obese (BMI > or =30 kg/m(2)). Obese patients were younger, more often African American, and more likely to have a history of antecedent hypertension, but less likely to have coronary artery disease and with only a trend toward diabetes mellitus. Levels of BNP were significantly lower in obese than in nonobese subjects (205 +/- 22 and 335 +/- 39 pg/ml, respectively; p = 0.0007), despite a similar severity of heart failure and cytokine levels. Multivariate regression analysis identified BMI as an independent negative correlate of BNP level. There were no differences in emergency department visits, heart failure hospitalization, or death between the obese and nonobese patients at 12-month follow-up.Conclusions Our investigation indicates that a state of reduced natriuretic peptide level exists in the obese individual with heart failure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
