Obesity is closely related to myocardial fibrosis, especially the correlation between visceral adipose tissue and myocardial fibrosis, which has attracted the attention of the medical community. A number of studies have confirmed that visceral adipose tissue participates in myocardial fibrosis by secreting a variety of adipocytokines such as leptin and adiponectin, and its mechanism of action is complicated. Recent studies have shown that visceral adipose tissue can also promote myocardial fibrosis by producing osteopontin. The emerging bioelectrical impedance analysis method for measuring visceral adipose tissue will also lay the foundation for further clinical application and research. This article reviews the involvement of visceral adipose tissue in the production of myocardial fibrosis and its determination method.
