Key result
Breast cancer survivors in the first year posttreatment had significantly higher heart rates (p<0.001) and lower heart rate variability (SDNN p=0.001) compared to healthy matched controls.

May indicate early autonomic imbalance in breast cancer survivors; hypothesis-generating for HRV monitoring, pending prospective validation.
Case-Control (n=44)
Does breast cancer survivorship in the first year posttreatment alter heart rate variability compared to healthy controls?
p-value: p=<.001
Breast cancer survivors exhibit cardiovascular autonomic imbalance in the first year post-treatment, suggesting HRV could be a useful tool for early detection of cardiovascular disease in this population.
Caro-Morán et al. (2015) conducted a case-control in Breast cancer (n=44). History of breast cancer treatments vs. Healthy age- and sex-matched controls was evaluated on Heart rate variability (HRV) (p=<.001). Breast cancer survivors in the first year posttreatment had significantly higher heart rates (p<0.001) and lower heart rate variability (SDNN p=0.001) compared to healthy matched controls.
