| Outline of Final Research Achievements |
The present study demonstrated that a balloon alone percutaneous coronary intervention (PCI) using drug coated balloon or ‘Stent-less PCI’ exhibited equivalent effects compared to PCI with drug eluting stents in coronary artery disease patients. After ‘Stent-less PCI’, anti-thrombotic agents can be reduced safely, because stent thrombosis or neo-atherosclerosis can be prevented. Therefore, coronary events and bleeding events will be prevented simultaneously and long term prognosis can be improved. In patients received ‘Stent-less PCI’ who plan to undergo non-cardiac surgeries, anti-thrombotic agents can be discontinued safely, and bleeding complications can be reduced. Additionally, when a patient after ‘Stent-less PCI’ will need coronary artery bypass grafting (CABG) in the future, there will be no coronary stent that might interfere in CABG.
‘Stent-less PCI’ should be performed in the patients whose coronary artery lesions can be dilated optimally only with balloon.
