We calculated relative risks (RRs) of cardiovascular disease mortality using Poisson regression, accounting for age- and race-specific rates in the general population, according to county-level quintiles of SES (measured by Yost index), median income, and rurality at breast cancer diagnosis. We also calculated 10-year cumulative mortality risk of cardiovascular disease accJNCI cancer spectrumpkac083https://www.ebi.ac.uk/biostudies/studies/S-EPMC9901273biostudies-literatureCounty-level geographic disparities in cardiovascular disease mortality among US breast cancer survivors, 2000-2018.PMC9901273Ramin CVo JBHo KLBerrington de Gonzalez AShiels MSVeiga LHSChen YfalseCounty-level geographic disparities in cardiovascular disease mortality among US breast cancer survivors, 2000-2018.<h4>Background</h4>Disparities in cardiovascular disease mortality among breast cancer survivors are documented, but geographic factors by county-level socioeconomic status (SES) and rurality are not well described.<h4>Methods</h4>We analyzed 724 518 women diagnosed with localized or regional stage breast cancer between 2000 and 2017 within Surveillance, Epidemiology, and End Results Program-18 with follow-up until 2018.
