OBJECTIVE
Associations between various plaque types in coronary and carotid arteries using multidetector row computed tomography (MDCT) have not yet been reported. We evaluated MDCT correlation of total plaque and various plaque subtypes in carotid and coronary arteries.
METHODS
We studied 62 patients who had both carotid and cardiac computed tomography angiography (CTA). The plaque in each vascular segment was classified as non-calcified, calcified or mixed.
RESULTS
The average age of this population was 68+/-22 years, 63% males. Total plaque in the carotid artery correlated with total, calcified and mixed plaque in the coronary artery (all P<0.001). Calcified plaque in the carotid artery was associated with total and calcified plaque in the coronary bed (P<0.001). Non-calcified coronary plaque was not associated with carotid plaque.
CONCLUSION
Total plaque in coronary and carotid arteries are highly correlated.
目的
利用多排螺旋计算机断层扫描（MDCT）尚未报道冠状动脉和颈动脉中各种斑块类型之间的相关性。我们评估了颈动脉和冠状动脉中总斑块和各种斑块亚型的 MDCT 相关性。
方法
我们研究了 62 例同时进行颈动脉和心脏计算机断层血管造影（CTA）的患者。每个血管节段的斑块均分为非钙化、钙化或混合。
结果
该人群的平均年龄为 68±22 岁，男性占 63%。颈动脉总斑块与冠状动脉总斑块、钙化斑块和混合斑块均相关（均 P<0.001）。颈动脉钙化斑块与冠状动脉总斑块和钙化斑块相关（均 P<0.001）。非钙化冠状动脉斑块与颈动脉斑块无关。
结论
冠状动脉和颈动脉的总斑块高度相关。
