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