U.S., May 30 -- ClinicalTrials.gov registry received information related to the study (NCT07613996) titled 'Impact of Hyperemic State on Angio-IMR Performance' on May 11.
Brief Summary: The goal of this observational study is to evaluate the diagnostic performance of angiography-derived microcirculatory indices (Angio-IMR) in assessing patients with stable angina or suspected coronary artery disease. The main questions it aims to answer are:
How do the numerical values of Angio-IMR from five different software vendors change across three physiological states (resting, sub-hyperemia induced by nitroglycerin, and maximal hyperemia induced by adenosine)? Which physiological state and software algorithm provide the highest diagnostic accuracy...
