A Prospective, Multi-center Clinical Trial for Evaluating the Effectiveness and Safety of Online Coronary Angiography-Derived Index of Microcirculatory Resistance (caIMR)

"caIMR will be measured by pressure sensors which are produced by Suzhou Rainmed Medical Technology Co., Ltd.~caIMR is calculated based on angiography images and Hyperemic Pa estimated from resting Pa according to prespecified equation."

"IMR will be measured by thermodilution method with pressure wire and arterial physiological detector which are produced by St. Jude Medical.~IMR = Pd ∙Tmn"
