AI-generated summary by claude@2026-07, 2026-07-17

This study found that heart rhythm complexity, measured by multi-scale entropy, was negatively correlated with age and positively correlated with Kt/V, albumin, and hemoglobin in hemodialysis patients, and was impaired both by age and hemodialysis itself.

This preprint studied heart rhythm complexity as non-linear heart rate variability in 31 patients with end-stage renal disease receiving haemodialysis, using multi-scale entropy (MSE) analysis of 24-hour ECG and examining relationships with clinical laboratory parameters and timing around dialysis sessions. The authors reported that MSE area was negatively correlated with age, while MSE area (10–20 scale) was positively correlated with Kt/V, albumin, and hemoglobin, and that MSE area was higher before than after haemodialysis, leading them to describe haemodialysis as a harmful factor for HRV. A key limitation explicitly indicated by the publication status is that the work is a Research Square preprint and “has not been peer reviewed by a journal.” This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Cardiovascular disease (CVD) is one of the most common complications of end stage renal disease (ESRD) patients receiving haemodialysis (HD). A better understanding of the relationship between CVD and HD is important to improve life expectancy and reduce the mortality risk of ESRD patients receiving HD. Heart rate variability (HRV), also known as variations in heart rate, is a useful method to measure the autonomic nervous system dys-regulation with 24-h electrocardiogram (ECG). The variables of heart rhythm complexity could be acquired with multi-scale entropy analysis (MSE). We enrolled 31 ESRD patients receiving HD in this study. MSE was used as non-linear heart rate variability (HRV) in our study. MSE area was negative correlated with age. MSE area 10-20 was positive correlated with Kt/V, albumin (ALB) and hemoglobin (Hb). Furthermore, we found that the MSE area before HD was higher than the MSE area after HD. We also found that increased age was a deleterious factor of HRV in ESRD patients receiving HD. Kt/V, ALB, and Hb were beneficial factors of HRV in ESRD patients receiving HD. HD seemed to be a harmful factor of HRV in ESRD patients.
