Inclusion criteria

Inclusion criteria: Patients who were suspected of having coronary artery disease by 64-slice MDCT before percutaneous coronary intervention (PCI) at our institution

Exclusion criteria

Exclusion criteria: 1. Chronic kidney disease manifested by an estimated glomerular filtration rate of < 40 mL/min/1.73 m2 2. Significant left main disease 3. Previously stented lesions. In addition, patients with extensively severe stenotic lesions which was anticipated difficulty in advancing the NIRS-IVUS catheter without plain old balloon angioplasty (POBA) using more than 2.0 mm of diameter were excluded. 4. Extremely calcified lesions treated with atheroablative device (e.g. Rotablator and Diamondback 360).
