Clinical Application of Coronary Angiography-Based Index of Microcirculatory Resistance in Various Types of Coronary Heart Disease
The coronary microcirculation plays a crucial role in the regulation of myocardial perfusion,and the index of microcirculatory resistance is the gold standard for assessing microcirculation function.With the development of computational fluid dynamics,the coronary angiography-based index of microcirculatory resistance has received increasing attention.This method does not require the use of pressure wires or hyperemic agents,and it has good diagnostic consistency with wire-based index of microcirculatory resistance.It has been applied in myocardial infarction,chronic coronary syndrome and non-obstructive coronary artery disease.This article reviews the clinical application of coronary angiography-based microcirculatory resistance index in various types of coronary heart disease.
