| description | <p>Abstract</p> <p>Background</p> <p>B-type natriuretic peptide (BNP), a member of the natriuretic peptide family, is a cardiac-derived secretory hormone with natriuretic, diuretic, and vasorelaxant activities. Intraabdominal fat accumulation is associated with atherosclerotic cardiovascular diseases and cardiac dysfunction. Circulating BNP levels are relatively low (within the normal limits) in obesity and the metabolic syndrome. However, the relationship between plasma BNP levels and visceral fat accumulation in general population has not been reported. The present study analyzed the relationships between plasma BNP levels and various clinical variables, including insulin, visceral and subcutaneous fat area (VFA and SFA, respectively), in normal Japanese men.</p> <p>Methods</p> <p>The study (Victor-J study) subjects were consecutive 500 Japanese male workers, who underwent a health checkup and were measured VFA and SFA by computed tomography.</p> <p>Results</p> <p>Age-adjusted simple linear regression analysis showed that log-BNP correlated positively with HDL-cholesterol, and negatively with VFA, log-immunoreactive insulin (IRI), log-triglyceride, and LDL-cholesterol, but not body mass index or SFA.

Subjects with IRI ≥5.5 μIU/mL had lower plasma BNP levels than those with IRI < 5.5 μIU/mL, irrespective of obesity (body mass index, cutoff value 25 kg/m<sup>2</sup>), visceral fat accumulation (VFA, cutoff value 100 cm<sup>2</sup>) and subcutaneous fat accumulation (SFA, cutoff value 128 cm<sup>2</sup>).</p> <p>Conclusions</p> <p>Our study showed that hyperinsulinemia correlated with low levels of plasma BNP in general men, irrespective of fat distribution.</p> <p>Trial registration</p> <p>UMIN 000004318.</p> |
