Perivascular adipose tissue (PVAT) envelops the majority of systemic vessels, providing crucial mechanical support and vessel protection. In physiological conditions, PVAT releases various bioactive molecules, contributing to the anti-inflammatory environment around neighboring vessels. However, in conditions like obesity, PVAT can exacerbate cardiovascular issues such as atherosclerosis. Communication between PVAT and nearby vessels is bidirectional, with PVAT responding dynamically to signals from the vasculature. This responsiveness positions PVAT as a promising indicator of vascular inflammation. Recently, the role of PVAT in the CVD risk prediction is also greatly discussed. The objective of this review is to summarize the current state of knowledge about the PVAT function, its role in physiologic and pathophysiologic processes and its potential in CVD risk prediction. Keywords: Perivascular adipose tissue, inflammation, atherogenesis, Fat attenuation index.
