Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the influence of total atherosclerotic burden assessed by 3-vessel fractional flow reserve (FFR) on the clinical outcomes of the patients with multi-vessel disease. For this purpose, the clinical data of the patients with 3-vessel intermediate coronary artery disease, whose FFR was measured at all 3-vessels due to their own clinical needs, will be analyzed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Analysis The Primary Analysis will be performed after 2-year follow-up data will be completed.

Pre-specified Subgroup Analysis

The pre-specified subgroup analysis will perform after 1-year follow-up data will be completed according to the following subjects:

* Concordant and discordant results between FFR and angiographic stenosis severity (patients and lesions with pre-PCI FFR will be analyzed.).

* Association between total atherosclerotic burden and total ischemic burden, coronary CT angiography substudy (after 2-year follow-up will be completed).

* Validation of total ischemic burden (sum of 3 vessel FFR) with Duke score, measured by treadmill test.

* Comparison of clinical outcomes of deferred lesions according to pre-PCI FFR levels (Pre-PCI FFR \<0.75, 0.75-0.80, and \>0.80).

* Comparison of clinical outcomes of deferred lesions according to iFR and FFR values ⑥ Prognosis of functional complete revascularization versus incomplete revascularization
