Patients with coronary microvascular dysfunction represent a widespread population, and despite the good prognosis, many of them, because of the angina symptoms, have a poor quality of life with strong limitations in their daily activities. In 2017, a new classification of microvascular dysfunction as well as a new definition of ischemia in patients with no obstructive coronary artery disease became available. This new definition improves Kemp's initial work, where cardiac X syndrome was initially described. This work summarizes the last updates on the subject with particular attention to the new classification of microvascular dysfunction, with particular attention to microvascular and vasospastic angina definition and diagnostic criteria.
患有冠状动脉微血管功能障碍的患者为数众多，尽管预后良好，但由于心绞痛症状，许多患者的生活质量较差，日常活动受到严重限制。2017 年，一种新的微血管功能障碍分类和一种新的无阻塞性冠状动脉疾病患者缺血定义出现了。这个新定义改进了 Kemp 的最初工作，最初在那里描述了心脏 X 综合征。这项工作总结了该主题的最新进展，特别关注微血管功能障碍的新分类，特别关注微血管性和血管痉挛性心绞痛的定义和诊断标准。
