Brief Summary

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

This study was a multicenter retrospective study that included intravascular ultrasound (IVUS) in patients with delayed stent insertion based on fractional flow reserve (FFR) in moderately narrowed coronary lesions. We would like to see the effect of lesion characteristics on clinical course.

Detailed Description

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

From January 2007 to August 2014, patients who meet the criteria for selection and exclusion from Keimyung University Dongsan Hospital, Seoul National University Hospital, Inje University Busan Paik Hospital, and Ulsan University Hospital are included.

1. Target patient screening The database will select patients who meet the selection and exclusion criteria.
2. target patient characteristics The age, sex, smoking status, medical history (hypertension, diabetes mellitus, hyperlipidemia), diagnosis, and left ventricular blood count measured by echocardiography should be checked through a computerized medical record.
3. coronary angiography Coronary angiography images of the subjects in the blinded state are analyzed to investigate the length of lesions, reference vessel diameter, and minimal vessel diameter.
4. intravascular ultrasound In the blinded state, the vessel's vessel area, plaque area, lumen area, etc. are measured by analyzing intravascular ultrasound images of the patient using EchoPlaque (Indec Systems, Mountain View, CA).
