Randomised trial of elective stenting after successful percutaneous transluminal coronary angioplasty of occluded coronary arteries

摘要

Conclusions-Intracoronary stent inser- tion is effective in reducing the rate of reocclusion and shows a trend towards reduced restenosis after opening of a total coronary occlusion by balloon angio- plasty. Sustained patency of the target coronary artery is associated with im- provement in global and regional left ven- tricular function. Background-The value of angioplasty in occluded coronary arteries is limited by a restenosis/reocclusion rate of 50-70/100. In Patients with subtotal occlusion, stent Implantation has been shown to reduce Clinical and angiographic restenosis.
