在另一项SCOT-HEART研究的事后分析中将正性重塑与低衰减斑块结合,只要符合其中一个特点就定义为不良斑块,发现存在不良斑块的患者出现心肌梗死的风险是无不良斑块患者的3倍,与是否存在>70%的狭窄一起使用预测效果更强。 图11 SCOT-HEART研究中不良斑块、狭窄...

摘要:【目的】基于CT冠状动脉造影图像计算虚拟血流储备分数使冠状动脉病变的功能无创评估成为可能,目前尚不清楚斑块是否会影响基于CTA虚拟计算的冠状动脉血流储备分数,本研究以有创FFR为参考标准,分析斑块对CT-QFR值的影响。【方法】回顾性研究纳入了...
1 CT 血流储备分数 ( CT derived fractional flow reserve,CT-FFR) FFR 是心肌最大充血状态下的 狭窄远端冠状动脉内平均压与冠状动脉口部主动脉 平均压的比值,能够反应冠状动脉的缺血性狭窄,以 及指导介入治疗,是评价冠状动脉生理功能的" 金 标准" ,但因其有创且价格昂贵,临床应用受限[17] . 近年来,CT-FFR...
