摘要

评估冠状动脉狭窄的功能意义以指导经皮冠状动脉介入治疗的方法很普遍,即在腺苷或三磷酸腺苷诱导的高血流状态下使用压力丝分流储备。然而,由于这种高血容量刺激的禁忌症和不良影响,以及压力导丝损伤血管的潜在风险,分数血流储备的使用可能会受到限制。本综述将讨论其他评估方法,包括各种高血容量剂、非高血容量压力比和基于血管造影的指数。

Functional assessment of coronary stenosis: alternative hyperemic, nonhyperemic, and angiographic indexes
Assessment of the functional significance of coronary artery stenoses to guide percutaneous coronary intervention is widely performed using pressure wire fractional flow reserve during adenosine-or adenosine triphosphate-induced hyperemia. However, the use of fractional flow reserve may be limited by the contraindications and adverse effects of this hyperemic stimulus, as well as the potential risk of vessel damage from the pressure wire. This review will discuss alternative evaluation methods, including various hyperemic agents, nonhyperemic pressure ratios, and angiography-based indices.
