Endothelial dysfunction after stenting and scaffolding of coronary arteries

Abstract

Coronary artery stenting is associated with endothelial dysfunction, probably caused by the mechanical injury as well as by the tissue reactions triggered by the metal, the polymer and the drug eluted by the stent. The clinical relevance, and the implications, of this dysfunction are still unclear. We revise the iterature on this topic and provide the first evidence regarding endothelial dysfunction after implantation of bioresorbable scaffolds.
