All

Inclusion criteria

Inclusion criteria: Measuring WSS and OSI in coronary lesions Measure WSS and OSI after bypass Patients with good bypass blood flow

Exclusion criteria

Exclusion criteria: Complex coronary artery lesions Patients with poor bypass blood flow

Design outcomes

Primary

Measure	Time frame
Preoperative coronary computed tomography (CT) will be performed on patients who are considering coronary artery bypass grafting to evaluate the hydrodynamics of the coronary lesion. The same evaluation will be performed after the patient's coronary artery bypass surgery to determine how the flow pattern has changed. The primary outcome is the completion of postoperative CT scan and hydrodynamic analysis. Translated with www.DeepL.com/Translator (free version)	—
