• Coronary microvascular function testing using functional coronary angiography (FCA) is underutilized for patients with an unmet need.
• 92% of patients undergoing FCA had an abnormal coronary microvascular pathway identified and 39% had abnormalities in all pathways tested demonstrating the complexity of the microvasculature.
• Call to action: (1) standardize terminology and definitions in microvascular dysfunction; (2) standardize FCA protocols; 3) investigate the agreement and interaction between different measures of microvasculature function.

用于冠状动脉微血管功能的功能性冠状动脉造影：时机已到！

• 对于需求未得到满足的患者，使用功能性冠状动脉造影 (FCA) 进行的冠状动脉微血管功能测试未得到充分利用。
• 92% 接受 FCA 的患者发现冠状动脉微血管通路异常，39% 的所有通路均出现异常，表明微血管系统的复杂性。
• 行动呼吁：(1) 规范微血管功能障碍的术语和定义；（2）规范FCA协议；3) 研究不同微血管功能测量之间的一致性和相互作用。
