Abstract Purpose: To explore cardiac autonomic changes assessed by linear and nonlinear indexes of heart rate variability (HRV) and body composition modifications in breast cancer survivors and cancer-free control women. Methods: Women who were breast cancer survivors (BCS, n=27) and cancer-free control participants with similar characteristics (Control, n=31) were enrolled in the Regional General Hospital No. 251 of the Mexican Institute of Social Security (Metepec, Mexico). We processed five minutes of R-R interval time series, and we calculated relevant linear and nonlinear parameters of HRV such as mean RR interval (RRave), the Root Mean Square of the Successive Differences (RMSSD), the Poincaré plot measures SD1, SD2, SD1/SD2, and the sample entropy (SampEn). Additionally, we indirectly assessed body composition measures such as body weight, fat mass, visceral fat rating (VFR), normalized VRF (nVFR), muscle mass, metabolic age, and total body water.Results: We found that diverse HRV indexes and only one body composition measure showed statistical differences (p<0.05) between the BCS and Control groups: RRave: 729 (648–802) vs. 795 (713–852) ms; RMSSD: 16.5 (8.9–27.0) vs. 19.7 (14.2–28.5) ms; SD1: 11.6 (6.3–19.0) vs. 13.9 (10.0–20.1) ms; SD1/SD2: 2.5 (2.1–3.3) vs. 2.2 (1.9–2.7), SampEn: 1.5 (1.3–1.8) vs. 1.7 (1.5–1.8), and nVFR 0.12 (0.11–0.13) vs.0.10 (0.08–0.12) points/kg, respectively. The nVFR was significantly correlated to several indexes of HRV.Conclusions: BCS exhibit a lower parasympathetic cardiac activity and changes in HRV patterns than controls, likely because of the concomitant increase of visceral fat.

Introduction: Breast cancer remains the most commonly type of cancer. Heart rate variability (HRV), a clinical indicator of autonomic dysfunction and premature mortality, has been found to be impaired in breast cancer survivors immediately after treatment and in the last stages of metastasis. Physical activity and fitness represent relevant health markers that might prevent some of the side effects following breast cancer treatment, so it would be of clinical interest assessing potential differences with healthy controls. Hypothesis: Compared to healthy women, breast cancer survivors are expected to show impaired HRV-derived parameters, as well as lower physical activity and fitness. Methods: This cross-sectional study included 20 women that survived breast cancer (post-operative period >2 years) and 20 healthy women controls, matched by age and BMI. Fitness evaluations included the modified Ruffier-Dixon test and handgrip strength. Moderate-to-vigorous physical activity (MVPA) was assessed through a self-reported questionnaire. Short-term HRV was measured using 5-minutes recording and were analyzed with Kubios Premium. Sample size was determined for two-tailed tests, statistical power of 0.8, effect size >0.7, and significance level of p<0.05. Between-groups differences were examined using Mann–Whitney U test and Student’s t-test, for normally and not-normally distributed variables, respectively. Results: Concerning HRV parameters, breast cancer survivors presented lower Very Low Frequency and Low Frequency, and higher Low Frequency/High Frequency ratio (all p <0.001), compared to controls. No statistically significant differences were observed in MVPA time ( p =0.48) or estimated VO 2max ( p =0.24), although handgrip strength was decreased in cancer survivors ( p =0.02). Conclusions: A cardiovascular imbalance in breast cancer survivors may be suggested in comparison to healthy age- and BMI-matched controls, as evidenced by reduced HRV after >2 years of post-operative treatment. In contrast, there were no differences in weekly MVPA or VO 2max between groups, although muscular strength could still be affected. These results need to be contrasted by future long-term prospective research.

AbstractThe aim of this study was to explore cardiac autonomic changes assessed by linear and nonlinear indexes of heart rate variability (HRV) and body composition modifications in breast cancer survivors and cancer-free control women. Women who were breast cancer survivors (BCS, n = 27) and without cancer with similar characteristics (Control, n = 31) were recruited for this study. We calculated some relevant linear and nonlinear parameters of 5 min of RR interval time series such as mean RR interval (RRave), the corrected Poincaré index (cSD1/SD2), the sample entropy (SampEn), the long-term fractal scaling exponent (α2) and 2UV from symbolic dynamics. Additionally, we indirectly assessed body composition measures such as body weight, fat mass, visceral fat rating (VFR), normalized VRF (nVFR), muscle mass, metabolic age, and total body water. We found that diverse HRV indexes and only one body composition measure showed statistical differences (p < 0.05) between the BCS and Control groups. RRave: 729 (648–802) vs. 795 (713–852) ms; cSD2/SD1: 3.4 (2.7–5.0) vs. 2.9 (2.3–3.5); SampEn: 1.5 (1.3–1.8) vs. 1.7 (1.5–1.8); α2: 0.6 (0.3–0.6) vs. 0.5 (0.4–0.5); 2UV: 7.1 (4.3–11.5) vs. 10.8 (6.4–15.7) and nVFR 0.12 (0.11–0.13) vs. 0.10 (0.08–0.12) points/kg, respectively. The nVFR was strongly significantly correlated with several indexes of HRV only in the BCS group.Our findings suggest that BCS exhibit lower parasympathetic cardiac activity and changes in HRV patterns compared to Controls. A concomitant increase of visceral fat, among other factors, may contribute to cardiac autonomic disturbances and changes in HRV patterns in BCS.

The same aggressive treatments that have led to a reduction in the breast cancer may also have adverse effects on cardiac autonomic balance. The objective of this study was to compare heart rate variability (HRV) between breast cancer survivors in the first year posttreatment and healthy women, controlling for known confounders. This descriptive case-controlled study included 22 breast cancer survivors and 22 healthy age- and sex-matched controls. Short-term HRV was measured using an accepted methodology to assess the cardiac autonomic balance. One-way analysis of covariance results revealed that heart rate was significantly higher ( F = 15.86, p < .001) and the standard deviation of normal-to-normal (NN) interval ( F = 19.93, p = .001), square root of mean squared differences of successive NN intervals ( F = 18.72, p = .001), HRV index ( F = 5.44, p = .025), and high-frequency ( F = 5.77, p = .03) values were significantly lower in the breast cancer survivors than in the matched controls. The principal finding of the presence of a cardiovascular imbalance in breast cancer survivors in comparison to healthy age-matched controls suggests that HRV study could be a clinically useful tool to detect cardiovascular disease in early-stage breast cancer survivors.

Background: Breast cancer is the most common malignancy among women worldwide. The treatments may also cause neuromuscular and skeletal disorders; therefore, the aim of this study was to verify the existence of a relationship between heart rate variability and different functional fitness parameters in women survivors of breast cancer. Methods: This cross-sectional study included 25 women survivors of breast cancer, with a mean ± SD age, height, and body mass of 50.8 ± 8.8 years, 1.6 ± 0.7 m, and 67.1 ± 12.3 kg, respectively. Patients underwent measurements of heart rate variability with time and frequency domain analyses, as well as a “30 s chair-stand test”, “6 min walking test”, “timed up and go test”, and “ball throwing test”. Results: A multiple linear regression analysis showed that from the heart rate variability frequency domain, high frequency explained 21% (R2 = 0.21) of the “30 s chair-stand test” performance. Conclusion: The findings of this study highlight high frequency as a predictor of “30 s chair-stand test” performance, regardless of age and time after diagnosis, suggesting its usefulness as a clinical indicator of functionality in breast cancer survivors. This study presents a straightforward and non-invasive methodology predicting functional fitness in women breast cancer survivors potentially applicable to clinical practice.
