摘要目的明确各CT冠状动脉指标与血流储备分数(FFR)≤0.8之间的独立相关性,综合各项指标以得出一个最能准确预测FFR≤0.8的分值,并评估此分值在预测FFR≤0.8中的诊断准确性。材料与方法此回顾性研究已经过伦理委员会批准,签署知情同意书。连续纳入的病人均采用CT冠状动脉成像及FFR对1支或多支中度狭窄血管进
Abstract Objective To clarify the independent correlation between the indexes of coronary arteries in each CT and the fractional flow reserve (FFR) ≤0.8, and to synthesize the indexes to get a score which can most accurately predict the FFR≤0.8 and evaluate the score at Predict FFR ≤ 0.8 in the diagnostic accuracy. Materials and Methods This retrospective study was approved by the Ethics Committee and signed informed consent. Continuous inclusion of patients with CT coronary angiography and FFR on one or more of the moderate stenosis
