Clinical Trial Summary

To compare low dose (1mg) pitavastatin and high dose (4mg) pitavastatin on neointimal hyperplasia and atherosclerosis progression by using optical coherence tomography (OCT) and near-infrared spectroscopy (NIRS) at 12 months follow-up and on clinical adverse cardiovascular events during 3-year follow-up.

Description:

• Patients with non-ST elevation ACS will be randomized into pitavastatin 1mg or 4mg after everolimus-eluting stent implantation with OCT and NIRS study.

• 12 months follow-up coronary angiography with OCT and NIRS will be performed to compare neointimal hyperplasia and atherosclerosis progression.

• 36 months clinical follow-up for major adverse cardiovascular events (cardiac death, all-cause death, myocardial infarction, stroke, target lesion revascularization) will be compared.

• Safety issues such as bleeding rates, abnormal liver function will be compared

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Neointimal volume with OCT (mm3 per 1mm) and lipid volume with NIRS (the maximal lipid core burden index (LCBI) in 4 mm segment during 12 months of treatment	OCT will measure neointimal volume in every mm interval and will be averaged by dividing the total neointimal volume with the number of the segment analyzed. LCBI is the lipid volume index which is calculated automatically by the device, and LCBI > 400 is considered high lipid volume.	12 months for OCT and NIRS
Secondary	Rates of major adverse cardiovascular events during 12 months follow-up	Major adverse cardiovascular events include all-cause death, cardiovascular death, myocardial infarction, stroke, target vessel revascularization	12 months for clinical events
