Abstract
The relationship between stent design and periprocedural myocardial infarction is unclear. The newest type of drug-eluting stent (DES), the everolimus-eluting stent (EES), has thinner strut and polymer thickness and a small amount of drug. EES use, therefore, could be related to less myocardial necrosis post-percutaneous coronary intervention (PCI). This study was undertaken to compare the amount of myocardial necrosis associated with implantation of the four DES types currently approved in the U.S.
