Clinical Trial Summary

The current study evaluated prognostic implication of comprehensive physiologic assessment using fractional flow reserve, coronary flow reserve (CFR) and index of microcirculatory resistance (IMR).


Clinical Trial Description

The patient-level data was gathered from 3 nations (Korea, Japan, Spain). The total 1397 patients (1694 vessels) data was collected from 5 university hospitals in Korea (Seoul National University Hospital, Samsung Medical Centre, Inje University Ilsan Paik Hospital, Keimyung University Dongsan Medical Centre, and Ulsan University Hospital, Korea) and Tsuchiura Kyodo General Hospital, Ibaraki, Japan, and Hospital Clinico San Carlos, Madrid, Spain.

Standardized form of data collection sheet was used and all study adopted standardized definition of patient's baseline characteristics, clinical outcomes, and physiologic data. In case of acute coronary syndrome (unstable angina, non-ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction), only non-culprit vessel was included in the data.

Primary outcome is patient- and vessel-oriented composite outcome at 5 years. ;
