| 中文摘要: |
| 急性主动脉夹层是心血管系统病死率极高的一种急危重症,传统危险因素难以解释它的发病机制和预后差异。体成分异常是可干预的因素,近年来越来越受关注。借助CT、MRI和超声等影像技术,能无创量化内脏脂肪面积、骨骼肌面积及肌肉密度(即肌肉脂肪浸润程度)等体成分指标。本文围绕肥胖、肌少症和肌少性肥胖,梳理其与AAD的流行病学关联、病理生理机制及预后影响,分析影像方法的适用性,并提出基于体成分影像指标的风险评估与管理建议,为AAD精准防治提供新思路。 |
| 英文摘要: |
| Acute aortic dissection (AAD) is a severe, life-threatening cardiovascular emergency associated with an exceedingly high mortality rate. Conventional risk factors fail to fully account for its pathogenesis and heterogeneous prognosis. Abnormal body composition, as a modifiable risk factor, has attracted growing research attention in recent years. Imaging modalities including CT, MRI and ultrasound enable non-invasive quantification of body composition parameters such as visceral fat area, skeletal muscle area and muscle density (namely the extent of myosteatosis). Focusing on obesity, sarcopenia and sarcopenic obesity, this review summarizes their epidemiological links to AAD, underlying pathophysiological mechanisms and prognostic effects, evaluates the feasibility of relevant imaging techniques, and proposes risk stratification and management recommendations based on imaging-derived body composition parameters, providing new insights for the precision prevention and treatment of AAD. |
