- 血管炎症诱导PVAT的形态变化,可量化为皮冠状脂肪组织 (PCAT) 的衰减增加.
- 脂肪减弱指数 (FAI) 衡量PCAT减弱,与冠状动脉疾病 (CAD) 的存在,进展和斑块不稳定性相关.
研究的目的:
- 审查PVAT与血管壁之间的相互作用.
- 讨论PCAT减弱作为心血管疾病 (CVD) 风险标志物的诊断和预后价值.
- 为突出发展的医疗器械标准化FAI测量临床整合的医疗设备.
主要方法:
- 对PVAT与血管壁相互作用的现有文献的综述.
- 使用冠状动脉计算机断层扫描血管学对PCAT衰减量化的分析.
- 一种新型医疗器械的描述,旨在标准化FAI测量.
主要成果:
- 通过FAI测量的PCAT衰减是CAD的显著成像生物标志物.
- FAI显示了超越传统方法改善心脏风险分层的潜力.
- 在PCAT减弱测量的变化受到技术,生物学和解剖学因素的影响.
结论:
- 标准化的FAI测量对于将这种研究工具纳入临床实践至关重要.
- 开发的医疗器械旨在克服FAI测量变量的当前局限性.
- 作为心血管疾病的创新预后生物标志物,PCAT减弱具有前景.
