abstract = {Cardiovascular disease (CVD) is the leading cause of death
worldwide. The aim of this study was to examine if CVD
affects the mortality of women after a breast cancer
diagnosis and population controls differently.The analysis
included a total of 3,555 women, diagnosed with primary
stage 1-3 breast cancer or in situ carcinoma between 2002
and 2005 and 7,334 controls breast cancer-free at
recruitment, all aged 50-74 years, who were followed-up in a
German breast cancer case-control study until June, 30 2020.
Kaplan-Meier and cumulative incidence function were
calculated for all-cause mortality and mortality from any
cancer, stratified for case-control status and CVD,
separately for women aged < 65 and ≥ 65 years. Cox
regression and Fine-Gray subdistribution hazard models were
used to estimate hazard ratios (HR) and $95\%$ confidence
intervals $(95\%$ CI) for the association between
case-control-status, CVD and mortality from all causes/any
cancer.The median follow-up was 16.1 years. In total, 1,172
cases $(33.0\%)$ and 1,401 initial controls $(19.1\%)$ died.
CVD prevalence at recruitment was $15.2\%$ in cases and
controls. Cases with CVD had the highest and controls
without CVD the lowest mortality during the entire
observation period in both age groups (< 65 and ≥ 65
years). CVD was identified as a risk factor for all-cause
mortality in both cases and controls aged < 65 years (HR
1.22, $95\%CI$ 0.96-1.55 and HR 1.79, $95\%CI$ 1.43-2.24) as
well as at ages of ≥ 65 years (HR 1.44, $95\%CI$ 1.20-1.73
and HR 1.59, $95\%CI$ 1.37-1.83). A significant association
of CVD and cancer mortality was found only for cases aged
≥ 65 years.CVD was significantly associated with all-cause
mortality of both cases and controls and CVD was identified
as a risk factor for cancer mortality of cases aged ≥ 65
years at recruitment. Therefore, attention should be paid on
monitoring and preventing CVD in breast cancer patients,
especially in those diagnosed at older ages.},
