Why the study?
Does placement of a self-expanding coronary-artery stent prevent occlusion or restenosis in patients with coronary artery disease?
Does placement of a self-expanding coronary-artery stent prevent occlusion or restenosis in patients with coronary artery disease?
The use of self-expanding coronary-artery stents is limited by frequent early and late occlusions or restenosis, leaving their clinical utility uncertain.
Frequent early/late failures limit clinical adoption of self-expanding stents; leaves open their utility in coronary disease pending randomized trials.
Early occlusion remains an important limitation of this coronary-artery stent. Even when the early effects are beneficial, there are frequently late occlusions or restenosis. The place of this form of treatment for coronary artery disease remains to be determined.
