摘要
冠状动脉血流储备分数(FFR)能评估狭窄血管功能,指导血运重建,但因其检测费用昂贵且因使用腺苷而存在潜在风险,故其在临床上的应用并不广泛。瞬时无波形比值(iFR)与FFR类似,均是反映冠状动脉内压力的临床指标,但其检测不需要使用腺苷。笔者通过检索国内外相关文献,分析iFR与FFR的相关性,以探究iFR指导血运重建的有效性及安全性。
Coronary flow reserve fraction(FFR)can evaluate the function of stenosed vessels and guide revascularization.However,it is not widely used in clinic because of its high cost and potential risks due to the use of adenosine.The instantaneous wave-free ratio(iFR)is similar to FFR,which is a clinical indicator of intracoronary pressure.By searching the relevant literature at home and abroad,analyzed the correlation between iFR and FFR,in order to explore the effectiveness and safety of iFR in guiding revascularization.
