Book Description
Understanding the Potential Mechanisms by which Peri-vascular Adipose Tissue (PVAT) contributes to obesity-related Cardiovascular Diseases (CVDs)., Obesity is a fast-growing problem that is reaching epidemic magnitudes worldwide, affecting both children and adults. It is associated with increased risk of: ü premature death, ü morbidity, and ü mortality from several cardiovascular diseases (CVDs), including: ü stroke, ü coronary heart disease (CHD), ü myocardial infarction, and ü congestive heart failure. Although several studies have substantiated that obesity confers an independent and additive risk of all-cause and cardiovascular death, there is significant variability in these associations, with some lean individuals developing diseases and others remaining healthy despite severe obesity, the so-called metabolically healthy obese. Part of this variability has been attributed to the heterogeneity in both the distribution of body fat and the intrinsic properties of adipose tissue depots, including: ü developmental origin, ü adipogenic and proliferative capacity, ü glucose and lipid metabolism, ü hormonal control, ü thermogenic ability, and ü vascularization. In obesity, these depot-specific differences translate into specific fat distribution patterns, which are closely associated with differential cardiometabolic risks. The adventitial fat layer, also known as perivascular adipose tissue (PVAT), is of major importance. Similar to the visceral adipose tissue, PVAT has a pathophysiological role in CVDs. PVAT influences vascular homeostasis by releasing numerous vasoactive factors, cytokines, and adipokines, which can readily target the underlying smooth muscle cell layers, regulating the vascular tone, distribution of blood flow, as well as angiogenesis, inflammatory processes, and redox status. An effort has been made in this Booklet to summarize the current knowledge and discuss the role of PVAT within the scope of adipose tissue as a major contributing factor to obesity-associated cardiovascular risk along with several relevant illustrations. …Dr. H.
