主要结果指标

结果测量
措施说明
大体时间
Target Vessel Revascularization at 9 Months
大体时间:9 months
Target vessel revascularization (TVR) was defined as percutaneous revascularization or bypass of the target lesion or any segment of the artery containing the target lesion. The percentage of participants requiring revascularization of the target vessel was determined by stenosis of > 50% confirmed by angiography.
9 months

次要结果测量

结果测量
措施说明
大体时间
Systolic Velocity Ratio (SVR) > 2.0
大体时间:9 months
The percentage of participants with a systolic velocity ratio > 2.0 assessed using lower extremity arterial duplex ultrasound.
9 months
Change From Baseline in Walking Impairment Questionnaire (WIQ) Score
大体时间:Baseline and Month 9
The Walking Impairment Questionnaire (WIQ) is utilized to characterize a patient's walking ability. Scores range from 0 (no difficulty) to 100 (much difficulty).
Baseline and Month 9
Decrease in Ankle Brachial Index (ABI) > 0.15
大体时间:Baseline and Month 9

The percentage of participants with a decrease in the Ankle Brachial Index (ABI) > 0.15.

Ankle Brachial Index = Systolic Ankle Pressure / Systolic Brachial Pressure.

Baseline and Month 9
Target Lesion Revascularization (TLR) at 9 Months
大体时间:9 months
Target lesion revascularization (TLR) was defined as repeat percutaneous intervention or bypass surgery of the previously treated target lesion (or blockage). The percentage of participants requiring revascularization of the target lesion was determined by stenosis of > 50% confirmed by angiography.
9 months
Number of Deaths
大体时间:Up to 11 months
Number of patients who died due to any cause.
Up to 11 months
Number of Participants With Myocardial Infarction (MI)

The number of patients experiencing Myocardial Infarction (MI) during the study. Myocardial Infarction was defined as new pathologic Q waves of at least 0.04 seconds, or an increase in serum creatine kinase to more than twice the normal code together with a pathologic increase in myocardial isoenzymes.
Up to 11 months
Number of Participants With a Stroke
大体时间:Up to 11 months
The number of patients experiencing a stroke during the study. Stroke was defined as any sudden development of neurological deficits lasting more than 24 hours, and if a brain imaging study is performed it shows an infarction or hemorrhage. A transient ischemic attack is a neurological deficit lasting less than 24 hours and, if an imaging study is performed, shows no evidence of infarction or hemorrhage.
Up to 11 months
Minimum Lumen Diameter
大体时间:9 months
Minimum lumen diameter (MLD) is defined as the smallest diameter in millimeters (mm) in the arterial segment of interest measured angiographically.
9 months
Late Loss
大体时间:Day 1 (following revascularization) and 9 months
Late loss is defined as minimum lumen diameter (MLD) immediately post-procedure minus MLD at the time of follow-up, in mm.
Day 1 (following revascularization) and 9 months
Percentage of Participants With Binary Restenosis
大体时间:9 months
Binary restenosis was defined by a >50% diameter stenosis at follow-up study, assessed by angiography.
9 months
Diameter Stenosis
大体时间:9 months
Diameter stenosis is calculated as [1 - (minimum lumen diameter (MLD) / reference vessel diameter)] * 100, where the reference vessel diameter is the vessel diameter measured in a healthy segment of the target vessel proximal as close as possible to the lesion.
