Hosts Mitsuaki Sawano, MD, Kentaro Ejiri, MD, and Nobuhiro Ikemura, MD, welcome Yuki Obayashi, MD, of Leiden University Medical Center, to discuss findings from the STOPDAPT-3 trial. Dr. Obayashi highlights that, among ACS patients—including those with HBR or STEMI—aspirin and clopidogrel monotherapy after 1 month of DAPT resulted in similar rates of ischemic and bleeding events. These results support flexible, patient-centered antiplatelet strategies beyond the acute phase.
