J Am Coll CardiolPublished

  • Prospective cohort study

Authors' conclusion

In an older female cohort, key CHIP subtypes (TET2, ASXL1, and JAK2) were associated with incident CVD, with associations that appeared to differ by CVD outcome.

Study context

Population
Older women in the Women's Health Initiative Long Life Study (median age 80 years)
Participants
6,677 women
Exposure
Clonal hematopoiesis of indeterminate potential (CHIP) vs no CHIP
  • Composite CHIPn = 2,176
Outcome
Incident CHD
Follow-up
Median 10.1 years
