Abstract:
With the deepening of the research on coronary artery related diseases,people gradually realize that coronary microcirculation disorders have an important impact on the occurrence,development,curative effect and prognosis of cardiovascular diseases,and coronary microcirculation diseases have received more and more attention in ischemic heart disease.Since coronary microvessels cannot be directly observed through imaging,there are currently some indicators to evaluate coronary microcirculation function in clinical practice,among which the index of microcirculatory resistance(IMR)is widely used for the evaluation of coronary microcirculation function.Computational fluid dynamics derived IMR is accurate,easy to perform,and has a broad application prospect.This article provides a comprehensive review of the establishment,development,clinical applications,and progress of IMR.
