In this study, the investigates try to confirm our hypothesis that low dose ticagrelor(60mg) had similar anti-platelets function compared with the standard dose ticagrelor in senior （no less than 75 years old)acute coronary syndrome patients . Totally 40 senior ACS patients will be divided into 2 groups randomly one month after PCI . Group 1 will be treated with ticagrelor 90mg and aspirin 100mg after PCI for 12 months as the standard group; Group 2 will be treated with ticagrelor 60mg plus aspirin 100 mg for 11 months after one month standard DAPT treatment. The platelets function will be tested in VASP and TEG methods 2 months after PCI as the primary endpoints.The clinical events will be observed 12 months after PCI.
