在 Ach 激发试验中评估心肌乳酸生成对于诊断冠状动脉微血管痉挛至关重要且可行。该程序通常对于检测微血管痉挛的发生是安全且直接的,这在任何其他成像设备上通常都不可见 在开始手术之前,确保在接受乙酰胆碱激发试验以诊断血管痉挛性心绞痛或血管痉挛引起的微血管性心绞痛的患者中测量心肌乳酸的产生。此外,确保患者在导管插入术前至少 48 小时停用所有血管活性药物。
接下来,剃掉患者穿刺部位的毛发,包括腹股沟区域和手腕。麻醉后,穿刺部位在超声引导下通过右股静脉或左股静脉放置两个五法式静脉鞘。

Summary
冠状动脉痉挛激发试验期间心肌乳酸生成(冠状动脉-静脉血清乳酸水平差异)被认为是反映乙酰胆碱诱导的微血管痉挛引起的心肌缺血的高敏感标志物。本文介绍了评估心肌乳酸生成以诊断冠状动脉微血管痉挛的程序。
