Comparative Evaluation of Resting and Hyperemic Angiography‐Derived Index of Microcirculatory Resistance in Chronic Coronary Syndrome
xaIMR, especially derived from hyperemic angiography, is a reliable, noninvasive alternative to wire-based IMR for assessing coronary microcirculatory resistance in chronic coronary syndrome. However, resting angiography-derived xaIMR may have limited diagnostic accuracy in patients with reduced coronary flow reserve. Further studies are warranted to validate these findings in broader populations.
