Study on coronary plaque characteristics and CT-FFR of thoracic arthralgia based on SSF2 technique
胸痹症基于SSF2技术的冠脉斑块特征及CT-FFR初探

摘要

目的 探讨基于SSF2技术的冠脉斑块特征及CT-FFR应用于胸痹症的临床价值。方法 选择蚌埠市中医医院110例胸痹症患者为观察对象，来源于2022年8月～2024年5月行冠状动脉CT造影的病例，比较不同证型患者CT-FFR结果和冠状动脉斑块特征。结果 气滞血瘀证的混合斑块占比更高，风阳上扰证的非钙化斑块占比更高，气阴两虚证的钙化斑块占比更高；左前降支CT-FFR中，气滞血瘀证较其他分型更低（P＜0.05）。结论 基于SSF2技术下，不同胸痹症分型的冠脉斑块和CT-FFR具有特征性表现。

Abstract

Objective To investigate the characteristics of coronary plaque based on SSF2 technique and the clinical value of CT-FFR in thoracic arthralgia.
Methods A total of 110 thoracic arthralgia patients from Bengbu Hospital of Traditional Chinese Medicine were selected as the observation objects, from the patients who underwent coronary CT angiography (CCTA) from August 2022 to May 2024. CCTA was obtained by SSF2 reconstruction technique in all patients, and CT-FFR results and coronary plaque characteristics of patients with different syndrome types were compared.
Results The characteristics of plaque in different TCM syndrome differentiation types were different and regular. The proportion of mixed plaques in Qi-stagnation and blood-stasis syndrome was higher, the proportion of non-calcified plaques in wind-yang upper disturbance syndrome was higher, and the proportion of calcified plaques in Qi-yin deficiency syndrome was higher. In left anterior descending branch CT-FFR, Qi-stagnation and blood-stasis syndrome was lower than other types (P < 0.05).
Conclusion   Based on SSF2 technique, coronary plaques and CT-FFR of different thoracic types have characteristic manifestations.
