The plasma B-type natriuretic peptide (BNP) concentration was recently shown to be inversely correlated with body mass index (BMI). However, very few attempts have been made to associate abdominal obesity and BNP in the Japanese general population. Here, we conducted a cross-sectional study, and examined 339 male and 429 female residents without heart disease in a rural Japanese community who received an annual health checkup in 2006. BNP was inversely associated with both BMI and abdominal circumference (AC) in the age-adjusted regression analysis (p < 0.05). Following adjustment for traditional risk factors, multiple regression analysis revealed that BNP was negatively correlated with AC (p < 0.05), but not BMI. Although metabolic syndrome was not associated with BNP levels, AC had an influence on low BNP levels in the multiple regression analysis using both AC and BMI concurrently (p < 0.05 for AC and p > 0.60 for BMI). These effects were more prominent in men than in women. Collectively, plasma BNP levels are inversely related with obesity, as measured by AC, in Japanese community-based subjects.

Epidemiological studies have recently shown that obesity, and abdominal obesity in particular, is an independent risk factor for the development of heart failure (HF). Higher cardiac oxidative stress is the early stage of heart dysfunction due to obesity, and it is the result of insulin resistance, altered fatty acid and glucose metabolism, and impaired mitochondrial biogenesis. Extense myocyte hypertrophy and myocardial fibrosis are early microscopic changes in patients with HF, whereas circumferential strain during the left ventricular (LV) systole, LV increase in both chamber size and wall thickness (LV hypertrophy), and LV dilatation are the early macroscopic and functional alterations in obese developing heart failure. LV hypertrophy leads to diastolic dysfunction and subendocardial ischemia in obesity, and pericardial fat has been shown to be significantly associated with LV diastolic dysfunction. Evolving abnormalities of diastolic dysfunction may include progressive hypertrophy and systolic dysfunction, and various degrees of eccentric and/or concentric LV hypertrophy may be present with time. Once HF is established, overweight and obese have a better prognosis than do their lean counterparts with the same level of cardiovascular disease, and this phenomenon is called "obesity paradox". It is mainly due to lower muscle protein degradation, brain natriuretic peptide circulating levels and cardio-respiratory fitness than normal weight patients with HF.

Abdominal obesity and elevated blood pressure commonly occur in the same patient and are key components of the metabolic syndrome. However, the association between obesity and increased blood pressure is variable. We review mechanisms linking cardiovascular and metabolic disease in such patients including altered systemic and regional hemodynamic control, neurohumoral activation, and relative natriuretic peptide deficiency. Moreover, we discuss recent results using omics techniques providing insight in molecular pathways linking adiposity, metabolic disease, and arterial hypertension. Recognition of the mechanisms orchestrating the crosstalk between cardiovascular and metabolic regulation in individual patients may lead to better and more precise treatments. It is reassuring that recently developed cardiovascular and metabolic medications may in fact ameliorate, both, cardiovascular and metabolic risks.
