title: Effect of coronary endothelial function on outcomes in patients undergoing percutaneous coronary intervention.
abstract: Numerous studies have documented the association between endothelial dysfunction and adverse cardiovascular events. For example, coronary artery disease is associated with functional and structural changes of the coronary arteries, resulting in ischemia or plaque rupture, and is highly associated with endothelial dysfunction. Recent data suggest that implantation of drug-eluting stents (DES) can induce coronary artery endothelial dysfunction at follow-up when compared with bare-metal stents (BMS) and that this endothelial dysfunction may be associated with late stent thrombosis. Indeed, despite the superiority of DES in preventing restenosis, the incidence of death and myocardial infarction is similar when comparing DES with BMS. Medical treatment, such as statins, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers, can improve endothelial dysfunction. Thus, administration of these drugs along with percutaneous coronary intervention (PCI) may be a low-risk strategy to provide therapeutic benefit by stabilizing unstable plaque or by suppressing new lesion formation in patients undergoing PCI.
