    Background: Breast cancer survivors (BCS) may have a greater risk for cardiovascular disease [congestive heart failure (CHF) and hypertension (HTN)], which in turn, can affect cognitive dysfunction, a frequent, bothersome, and potentially debilitating symptom. Objective: The purpose of this study was to examine the relationship of cardiovascular disease on cognitive function in BCS. Methods: Baseline data from a double-blind RCT for cognitive training of BCS were examined. Early stage BCS (Stage I-IIIA) who were ≥21 years of age, completed adjuvant therapy (≥ 6 months), and reported cognitive concerns completed questionnaires and a brief neuropsychological assessment, including tests of memory, attention and working memory, speed of processing, and verbal fluency. Descriptive statistics, Pearson’s correlation coefficient and separate linear regression models for each cognitive domain were conducted. Results: 47 BCS, who were on average 57.3 (SD=8.1) years old, 58% White and had some college education (75%), completed the study. 44.7% of the BCS had cardiovascular disease (CHF or HTN). In linear regression models, cardiovascular disease was significantly related to immediate and delayed memory and attention and working memory (p<0.01–0.05). Conclusions: BCS who have cardiovascular disease may also be at a greater risk for cognitive dysfunction post-treatment. Results from this study inform both clinical practice and future research, specifically by examining the intersect between cancer, cardiovascular disease (cardiotoxicity), and cognition. Implications for Practice: Nurses should be aware that BCS with co-occurring cardiovascular disease are at higher risk for cognitive dysfunction, and work within the multidisciplinary team to optimize BCS health and function.
