Abstract

GARCIA ROSA¹, Maria Luiza et al. O papel do tecido adiposo na obesidade e na insuficiência cardíaca. Insuf. card. [online]. 2019, vol.14, n.2, pp.46-55. ISSN 1852-3862.

Introduction. Obesity, an important risk factor for the development of heart failure (HF), is a protective prognostic factor. This paradox can be explained by the protective role of brown adipose tissue (BAT), anti-inflammatory adipokines and the crosstalk between adipose tissue and heart mediated by natriuretic peptides (NPs). Material and methods. Evidence for these three mechanisms is discussed. Results. In animals and humans models, in both, obese and patients with HF, there is an increase in BAT, but it is less active, with lower expression of uncoupling protein type 1 (UCP1), limiting its protective potential. The antiinflammatory effect of some adipokines is associated with myocardial regeneration, production of new blood vessels, reduction of afterload and potentiation of metabolic processes in cardiomyocytes. It has been shown that NPs, in addition to their role in circulatory homeostasis, play a role in the energy tightening and regulation of adipose tissue, interfering with the release of adipokines. It is known that NPs are decreased in obese, due to a greater clearance or lower secretion. Conclusion. The role of anti-inflammatory adipokines and the crosstalk between adipose tissue and heart mediated by NPs are promising mechanisms to explain the paradox of obesity in HF. We found only two studies on the antiinflammatory role of adipokines, with direct evidence. Despite the existence of numerous studies on NPs, the evidence is less consistent. This area deserves to be followed in an attempt to understand the paradox of obesity in HF, which could allow a better care to the patient affected.
