Abstract

Approximately half of all coronary angiograms performed for angina do not show obstructive coronary artery disease, and many of these patients have coronary microvascular dysfunction (CMD). Invasive testing for CMD has increased with the advent and wider availability of thermodilution systems. We review CMD pathophysiology and invasive diagnostic testing using the Doppler and thermodilution systems. We report the results of a PubMed search of invasive microvascular testing and discuss limitations of current diagnostic algorithms in the diagnosis of CMD, including controversies regarding the optimal cutoff value for abnormal coronary flow reserve, use of microvascular resistance indices, and options for increasing sensitivity of testing.

冠状动脉无阻塞性心绞痛患者冠状动脉微血管功能障碍侵入性诊断的发展与争议

在所有因心绞痛而进行的冠状动脉造影检查中，约有一半没有显示阻塞性冠状动脉疾病，其中许多患者存在冠状动脉微血管功能障碍（CMD）。随着热稀释系统的出现和普及，CMD 的侵入性检测也在增加。我们回顾了 CMD 的病理生理学以及使用多普勒和热稀释系统进行的有创诊断测试。我们报告了有关有创微血管检测的 PubMed 搜索结果，并讨论了当前诊断 CMD 算法的局限性，包括有关冠状动脉血流储备异常的最佳临界值、微血管阻力指数的使用以及提高检测灵敏度的方案等方面的争议。
