摘要

血管周围脂肪衰减指数(FAI)已被认为是一种基于心脏计算机断层扫描(CCT)的冠状动脉炎症生物标志物。我们报告一例47岁女性急性自发性冠状动脉夹层(SCAD)累及左冠状动脉近端(LCA),接受了三次FAI。初始CCT扫描显示夹层LCA的血管周围FAI值较高。8天后进行的第二次CCT扫描显示,仅在左旋冠状动脉中持续存在较高的血管周围FAI值,其中发现狭窄严重程度和心肌梗死形成的进展。持续较高的血管周围FAI可能表明SCAD患者病情恶化。

Serial Change of Perivascular Fat Attenuation Index in a Case of Spontaneous Coronary Artery Dissection Involving the Proximal Left Coronary Artery.

The perivascular fat attenuation index (FAI) has been recognized as a cardiac computed tomography-based (CCT)-based biomarker of coronary inflammation. We report the case of a 47-year-old woman with acute spontaneous coronary artery dissection (SCAD) involving the proximal left coronary artery (LCA), who underwent FAI three times. The initial CCT scan revealed higher perivascular FAI values in the dissected LCA. The second CCT scan, performed 8 days later, showed persistence of a higher perivascular FAI value only in the left circumflex coronary artery, in which progression of stenotic severity and myocardial infarction formation were found. The persistence of a higher perivascular FAI may indicate disease deterioration in patients with SCAD.
