↵2-151 where exercise tolerance was very poor, metres walked was used as the exercise tolerance measure. ABI, ability index; ET, exercise tolerance on modified Bruce protocol or walking flat; FU, follow up; O2 sat; oxygen saturation in room air (pulse oximeter); PDS, pressure distal to stenosis; stent size (mm), diameter × length.
