Multicenter Registry for Instantaneous Wave-Free Ratio (iFR)-Guided Percutaneous Coronary Intervention in Routine Clinical Practice

Samsung Medical Center·observational·Posted Nov 9, 2017·Updated Mar 14, 2025

In Brief

An observational study evaluating Instantaneous wave-free ratio measurement for Stable Angina and 4 related conditions. Active but no longer recruiting, targeting 1,200 participants across 4 sites.

Detailed Summary

The current study sought to evaluate the clinical relevance of iFR-guided strategy in real world clinical practice using unrestricted study population from stable angina to acute coronary syndrome including acute ST-segment elevation myocardial infarction. Previous abundant historical data of FFR-guided strategy will be also included as historical control to validate the iFR-guided strategy.
