Obesity and particularly its deleterious form, visceral adiposity, has reached a high prevalence in the industrialized world owing to the lack of exercise and the widely available energy-dense diet. As a consequence, cardiovascular diseases and metabolic disorders are afflicting an unprecedented number of individuals at a world-wide scale. Over the last decades, investigations have established firm links between visceral obesity and the development of cardiovascular diseases. Moreover, studies in the field of lipid partitioning have demonstrated that inadequacy of homeostatic mechanism ensuring adequate handling of energy surplus is associated with accumulation of visceral fat and lipid overload of internal organs, which are participating to the development of heart diseases. Visceral obesity and its metabolic consequences often referred to as the metabolic syndrome is associated with the production of an atherosclerosis prone milieu. In this review, clinical implications of visceral obesity on the development of cardiovascular disorders are reviewed along with important mechanisms participating to the development of these disorders. Implications and failure of lipid partitioning and some of the potential pathways mediating development of heart diseases are also covered in view of recent development of therapeutic options.
由于缺乏运动以及能量密集型饮食随处可得,肥胖尤其是其有害形式——内脏型肥胖,在工业化世界已达到很高的患病率。因此,心血管疾病和代谢紊乱在全球范围内困扰着前所未有的大量人群。在过去几十年里,研究已确定内脏型肥胖与心血管疾病的发生之间存在着紧密联系。此外,脂质分配领域的研究表明,确保充分处理能量过剩的稳态机制不足与内脏脂肪堆积和内脏器官脂质过载有关,而这两者都参与了心脏病的发生。内脏型肥胖及其代谢后果通常被称为代谢综合征,与易于发生动脉粥样硬化的环境的产生有关。在这篇综述中,我们回顾了内脏型肥胖对心血管疾病发展的临床影响以及参与这些疾病发展的重要机制。鉴于治疗选择的最新进展,还涵盖了脂质分配的影响及缺陷以及一些介导心脏病发展的潜在途径。
