Hosts Mitsuaki Sawano, MD, Kentaro Ejiri, MD, and Satoshi Shoji, MD, welcome Dr. Shunsuke Inoue of The University of Tokyo to discuss clonal hematopoiesis of indeterminate potential (CHIP) and its cardiovascular implications. Dr. Inoue provides expert commentary on two recent JACC publications: a Women’s Health Initiative analysis linking CHIP mutations such as TET2, ASXL1, and JAK2 with distinct cardiovascular outcomes in older women, and an exploratory substudy of the LoDoCo2 trial examining whether low-dose colchicine modifies CHIP clone dynamics. Together, these studies highlight the complexity of CHIP as both a biomarker and a potential therapeutic target, raising new questions about how age, mutation subtype, and anti-inflammatory strategies intersect in cardiovascular risk.
