Key result
Chronic dermatoses were associated with a statistically significant decrease in LF and HF components of heart rate variability and an imbalance in autonomic nervous system regulation.
Why the study?
The study aimed to identify heart rate variability characteristics in patients with chronic dermatoses residing in the Middle Ob Region.
Do patients with chronic dermatoses exhibit altered heart rate variability compared to healthy controls?
Observational (n=111)
Do patients with chronic dermatoses exhibit altered heart rate variability compared to healthy controls?
Patients with chronic dermatoses exhibit significant alterations in heart rate variability, indicating autonomic nervous system imbalance.
The aim of the study was to identify the characteristics of heart rate variability (HRV) in patients with chronic dermatoses, citizens of the Middle Ob Region. Methods. 74 patients with chronic dermal diseases (psoriasis and eczema), as well as 37 people who were included in the control group, were examined using the method of variational pulse oximetry using the Elox-01 hardware complex and the ELOGRAPH software product. The assessment of the constituent characteristics of HRV was carried out using different approaches: methods of mathematical statistics using non-parametric tests of Wilcoxon, Shapiro-Wilk and multivariate analysis of multidimensional phase spaces, which determined the evidential base for quantitative measures and diagnostic markers (criteria) in disorders of neuro-vegetative regulation of cardiac function in patients with dermatoses. Results. Peculiarities of the heart rhythm structure were found in patients with dermal diseases: a statistically significant decrease in the LF and HF components was revealed and an imbalance was found in the regulation of the autonomic nervous system with a predominance of sympathetic imbalance in patients with dermatoses living in the Middle Ob region in the Khanty-Mansi Autonomous Okrug - Ugra. Diagnostic indicators of the characteristics of HRV in patients with eczema and psoriasis were determined, which made it possible to distinguish a complex of signs in the differences in the autonomic regulation of heart rhythm - Total P (mc2), VLF (mc2), LF (mc2) and the integral characteristics of HRV - Baevsky stress index (INB (cu), indicators of the sympathetic and parasympathetic system (SIM, PAR, cu). Conclusions. Patients with chronic dermatoses (psoriasis, eczema) living in severe climatic conditions of the Middle Ob Region have a tendency to early development of complicated forms of the disease with detection of imbalance in the regulation of the autonomic nervous system with a predominance of parasympathetic tone. The data obtained are important diagnostic aspects of the diseases pathogenesis, contributing to the determination of the further prognosis and correction of medical treatment.

Gorshkova et al. (2019) conducted an observational in Chronic dermal diseases (psoriasis and eczema) (n=111). Chronic dermatoses (psoriasis and eczema) vs. Control group was evaluated on Heart rate variability (HRV) characteristics including LF and HF components. Chronic dermatoses were associated with a statistically significant decrease in LF and HF components of heart rate variability and an imbalance in autonomic nervous system regulation.
