侵入性诊断程序,即所谓的IDP,可以识别功能性冠状动脉疾病,这是冠状动脉畅通的患者心绞痛的常见机制。IDP 使用冠状动脉内流量和压力测量对冠状动脉血管舒压的扩张和收缩成分进行全面评估。这是在休息和充血期间进行的,并且还要进行冠状动脉痉挛测试。
功能性冠状动脉疾病有不同的亚型,它们与不同的预后和治疗建议有关。IDP有助于做出诊断并找到最佳治疗方法。首先将适合左冠状动脉的引导导管放入左主动脉,再输送5, 000国际单位的肝素。

Summary
冠状动脉血管舒动障碍是冠状动脉畅通阻患者心绞痛的常见功能原因。这些患者心绞痛(内型)的潜在机制可以通过基于乙酰胆碱激发试验的综合侵入性诊断程序来确定,然后对冠状动脉血流储备和微血管阻力进行多普勒衍生评估。
