Gestational diabetes mellitus (GDM) is a common complication during pregnancy that poses considerable risks to both maternal and fetal health. However, its effect on cardiac autonomic function, measured by heart rate variability (HRV), remains uncertain. This study aims investigate potential alterations in function women diagnosed with GDM. In this cross-sectional study, 80 Kazakh pregnant their third trimester GDM were enrolled from the endocrinology department of Aktobe Medical Center between January April 2023. A control group 30 third-trimester without was also selected outpatient clinics City. HRV participants seated position. nomogram developed predict risk, integrating relevant parameters associated condition.

Maternal mental health conditions significantly contribute to pregnancy-related mortality in the United States. Approximately 20–25% of postnatal women exhibit symptoms depressive and anxiety disorders. Mental is influenced by stress, which affects mood, cognition, behavior. Heart rate variability (HRV), time interval between consecutive heartbeats, a physiological marker for assessing stress levels, providing critical insights into body’s autonomic responses. Wearable devices measuring HRV offer non-invasive method monitor health, enabling early detection maternal dynamics facilitate timely interventions. In this scoping review, we aimed capture current state science on two areas focus: (1) utilization wearable technology monitoring pregnant postpartum women, (2) findings from these perinatal studies, including observed trends throughout pregnancy postpartum, as well association HRV, health. The six included studies employed five fitness tracking wearables, utilizing either periodic or continuous 24-h monitoring. Findings include evidence that declines during pregnancy, with return normal levels postpartum. Associations were inconsistent across some demonstrating correlations others reporting no relationship. Postpartum measurements effectively differentiated depression (PPD) versus those adjustment disorder (AJD), high diagnostic accuracy. shows promise biomarker among pregnant/postpartum people, although more work needed standardize optimal methods measurement population.

Association of maternal nocturnal heart rate and adverse pregnancy outcomes

Abstract Introduction Prior data suggest that higher nocturnal heart rate may represent a marker of cardiometabolic disease risk in nonpregnant adults. Data on and pregnancy outcomes are limited. We sought to assess the association maternal with adverse outcomes. Methods This is secondary analysis nulliparas prospective cohort at eight US sites undergoing home sleep study using Embletta‐Gold device bipolar electrocardiogram baseline (6 0 –15 6 weeks) follow‐up (22 –31 visits. Exposures were mean, minimum, maximum (analyzed separately). Outcomes interest gestational diabetes, hypertensive disorders pregnancy, preterm birth, small‐for‐gestational age, stillbirth. Multivariable logistic regression models estimated odds each outcome, except for stillbirth due low frequency, per 5‐beat rate, adjusted possible confounders.

This study investigates the asymmetry in heart rate (HRA) during fetal development fetus and mother. R-R intervals from noninvasive maternal ECG signals 102 pregnant women whose gestational age ranges 20 to 40 weeks were analyzed. Several HRA indices, which evaluate accelerations decelerations RR interval time-series data, utilized examine variations both Results showed that 74.5% of mothers when measured using index Deceleration Input (DID2A). In fetuses, is driven by acceleration-to-deceleration transitions, while mothers, influenced deceleration-to-acceleration. Also, phase rectified signal averaging (PRSA) reveals acceleration deceleration capacities (AC DC) show significant correlations with (GA), indicating PRSA a promising tool for assessing development. also Porta Index (PI) associated sympathetic activity, behavioral state influences HRA. work provides new insights into asymmetry, leading deeper understanding health pregnancy.

(1) Background: Pregnancy induces significant physiological adaptations with substantial impacts on the cardiovascular system. Hypertensive disorders of pregnancy (HDPs) are connected to risks maternal and fetal complications, contributing significantly morbidity mortality across globe. This study focuses evaluating autonomic dysfunction by analyzing heart rate variability (HRV) assessing cardiac performance through global longitudinal strain (GLS) using speckle tracking echocardiography, as well examining diastolic function in pregnant women HDP compared healthy controls. (2) Methods: A case–control was conducted involving diagnosed gestational hypertension (GH), preeclampsia (PE), or severe (SPE) case group, control group. HRV measured evaluate function, GLS assessed evaluated standard echocardiographic parameters. Data were analyzed compare regulation between among different subgroups. (3) Results: The group exhibited reduced parameters controls, indicating notable dysfunction. Speckle echocardiography revealed lower HDP, particularly those SPE, Diastolic also present (4) Conclusions: valuable non-invasive tools for detecting impairments hypertensive disorders. These findings suggest that dysfunctions prevalent HDP.

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Авг. 27, 2024

Preterm birth (PTB) remains a global health concern, impacting neonatal mortality and lifelong consequences. Traditional methods for estimating PTB rely on electronic records or biomedical signals, limited to short-term assessments in clinical settings. Recent studies have leveraged wearable technologies in-home maternal monitoring, offering continuous assessment of autonomic nervous system (ANS) activity facilitating the exploration risk. In this paper, we conduct longitudinal study assess risk by examining ANS through heart rate (HR) variability (HRV). To achieve this, collect long-term raw photoplethysmogram (PPG) signals from 58 pregnant women (including seven preterm cases) gestational weeks 12–15 three months post-delivery using smartwatches daily life We employ PPG processing pipeline accurately extract HR HRV, an autoencoder machine learning model with SHAP analysis generate explainable abnormality scores indicative Our results reveal distinctive patterns during second pregnancy trimester, indicating potential early estimation. Moreover, find that HR, average interbeat intervals (AVNN), SD1SD2 ratio, standard deviation (SDNN) emerge as significant indicators.
