  • Prospective cohort study

Authors' conclusion

Higher LE8 scores were associated with a lower risk of incident CVD among women with BC in the United States.

Study context

Population
US women with breast cancer, Women's Health Initiative; median age 70.1 years at diagnosis
Participants
7,165 women
Exposure
Moderate and high vs low cardiovascular health before breast cancer (BC) diagnosis
Outcome
Composite of incident CVD events (CHD [MI with coronary revascularization], CVD death, stroke)
Follow-up
Median 6 years

Main finding
