To describe the link between adipocytes and cardiometabolic risk and present mechanisms by which obesity contributes to dysglycemia, dyslipidemia, hypertension, and a prothrombotic, inflammatory state favoring atherogenesis. Review of relevant literature compiled via a literature search (PUBMED) of English-language literature publications between 1994 and 2010. Cardiometabolic risk is a term that includes a series of conditions and factors, which contribute to increased risk of developing atherosclerosis. Cardiometabolic risk encompasses traditional coronary risks factors such as smoking, arterial hypertension, diabetes, obesity, elevated cholesterol, old age, male gender, and a positive family history of early coronary events plus additional contributing factors such as insulin resistance, atherogenic dyslipidemia, physical inactivity, unhealthy eating, inflammation, and hypercoagulable state. Adipocyte accumulation and dysfunction contribute to most, if not all, of the cardiometabolic risk factors. A number of different pathologic mechanisms through which adipocytes contribute to cardiometabolic risk and promote atherosclerosis are reviewed. Dysfunctional adipocytes are associated with the development of insulin resistance, hyperglycemia, atherogenic dyslipidemia and arterial hypertension, and favor a prothrombotic and proinflammatory state. Adipocytes dysfunction increases cardiometabolic risk through a variety of mechanisms.
描述脂肪细胞与心血管代谢风险之间的联系,并介绍肥胖导致血糖异常、血脂异常、高血压和促血栓形成、炎症状态从而促进动脉粥样硬化形成的机制。通过对 1994 年至 2010 年间发表的英文文献进行文献检索(PUBMED),综述相关文献。心血管代谢风险是一个术语,包括一系列增加发生动脉粥样硬化风险的病症和因素。心血管代谢风险包含传统的冠状动脉风险因素,如吸烟、动脉高血压、糖尿病、肥胖、胆固醇升高、年龄大、男性、早发冠状动脉事件阳性家族史,以及其他促成因素,如胰岛素抵抗、致动脉粥样硬化血脂异常、缺乏身体活动、不健康饮食、炎症和高凝状态。脂肪细胞堆积和功能障碍是导致大多数(如果不是全部)心血管代谢风险因素的原因。本文综述了脂肪细胞促进心血管代谢风险和动脉粥样硬化形成的多种不同病理机制。功能失调的脂肪细胞与胰岛素抵抗、高血糖、致动脉粥样硬化血脂异常和高血压的发生有关,并有利于促血栓形成和炎症状态。脂肪细胞功能障碍通过多种机制增加心血管代谢风险。
