| Outline of Final Research Achievements |
We examined the time course of coronary endothelial dysfunction after drug-eluting stent (DES) implantation, and evaluated whether it influence on cardiac function and long term clinical outcome. Vasomotor function of the infarct-related coronary artery and left ventricular function were measured at 2 weeks and 6 months after stent implantation in patients with acute anterior myocardial infarction. More than 4000 patients registered in the Yamanashi PCI (percutaneous coronary intervention) Registry, which was constructed with our 14 affiliated facilities, were followed for long term clinical outcome. At 2 weeks after stent implantation, endothelial dysfunction was less in the 2nd DES compared with 1st DES. Furthermore, the recovery of it was better in the 2nd DES compared with 1st DES at six months later. Because the follow-up periods were not enough, we could not conclude the long-term outcome. So, we will follow up our study patients, and present some data in the near future.
