DOI: 10.1016/s0735-1097(17)34440-6
Abstract: Background: Although lesion severity determined by coronary angiography is only moderately correlated with physiological stenosis significance, the mechanism of the discordance has not been fully elucidated, particularly with respect to the significance of microvascular function.… read more here.

DOI: 10.1016/s0735-1097(20)32350-0
Abstract: Plaque vulnerability as assessed using coronary CT angiography (CTA) affects fractional flow reserve (FFR). It is, however, unknown whether index of microcirculatory resistance (IMR) and coronary flow reserve (CFR) are associated with plaque stability similarly… read more here.

DOI: 10.1155/2020/4829647
Abstract: Background The index of microcirculatory resistance is an invasive measure of coronary microvascular function that has to be calculated during maximal hyperemia, classically achieved with intravenous adenosine (IV). The aim of this study was to… read more here.

DOI: 10.1161/circ.150.suppl_1.4142259
Abstract: Background: A reduction or delay in myocardial flow and perfusion, despite recanalization of the epicardial coronary arteries, is a well-known phenomenon. However, the association between microvascular resistance and troponin levels following elective percutaneous coronary intervention… read more here.

Invasive Assessment of the Coronary Microvasculature: The Index of Microcirculatory Resistance
Sign Up to like & getrecommendations! Published in 2017 at "Circulation: Cardiovascular Interventions"
DOI: 10.1161/circinterventions.117.005361
Abstract: Traditionally, invasive coronary physiological assessment has focused on the epicardial coronary artery. More recently, appreciation of the importance of the coronary microvasculature in determining patient outcomes has grown. Several invasive modalities for interrogating microvascular function… read more here.
