Sehun Kim, Donghoon Han, Jae Hyuk Choi, Eun-Joo Park, Dong Geum Shin, Min-Kyung Kang, Seonghoon Choi, Namho Lee, Jung Rae Cho
Korean J Intern Med. 2021;36(Suppl 1):S80-S89. Published online February 25, 2021
Background/Aims: Prolonged dual antiplatelet therapy (DAPT) with aspirin and clopidogrel beyond 1 year has been shown to reduce ischemic events at the expense of increased bleeding. However, limited data are available on the clinical significance of platelet reactivity (PR) at 1 year.
Methods: We r..
