Machine Learning Algorithms Combining Slope Deceleration and Fetal Heart Rate Features to Predict Acidemia

نویسندگان

چکیده

Electronic fetal monitoring (EFM) is widely used in intrapartum care as the standard method for well-being. Our objective was to employ machine learning algorithms predict acidemia by analyzing specific features extracted from heart signal within a 30 min window, with focus on last deceleration occurring closest delivery. To achieve this, we conducted case–control study involving 502 infants born at Miguel Servet University Hospital Spain, maintaining 1:1 ratio between cases and controls. Neonatal defined pH level below 7.10 umbilical arterial blood. We constructed logistic regression, classification trees, random forest, neural network models combining EFM acidemia. Model validation included assessments of discrimination, calibration, clinical utility. findings revealed that forest model achieved highest area under receiver characteristic curve (AUC) 0.971, but regression had best specificity, 0.879, sensitivity 0.95. In terms utility, implementing cutoff point 31% would prevent unnecessary cesarean sections 51% while missing only 5% acidotic cases. By variables recordings, provide practical tool assist avoiding sections.

Improving the Performance of Machine Learning Algorithms for Heart Disease Diagnosis by Optimizing Data and Features

Heart is one of the most important members of the body, and heart disease is the major cause of death in the world and Iran. This is why the early/on time diagnosis is one of the significant basics for preventing and reducing deaths of this disease. So far, many studies have been done on heart disease with the aim of prediction, diagnosis, and treatment. However, most of them have been mostly f...

Fetal acidemia and electronic fetal heart rate patterns: is there evidence of an association?

OBJECTIVE Despite the ubiquity of electronic fetal monitoring, the validity of the relationship between various fetal heart rate (FHR) patterns and fetal acidemia has not yet been established in a large unselected series of consecutive pregnancies. The aim of this study was to examine the published literature for evidence of such a relationship. METHODS Four hypotheses based on assumptions in...

Clinical Application of the Heart Rate Deceleration Capacity Test to Predict Epirubicin-induced Cardiotoxicity

OBJECTIVE To investigate the clinical value of heart rate deceleration capacity (DC) in predicting the risk of epirubicin-induced cardiotoxicity. METHODS The CK-MB and cTnI levels and DC values of 86 patients were examined before chemotherapy and again after 2 and 4 cycles of chemotherapy. Patients were divided into low-risk group (LRG) (40 cases), medium-risk group (26 cases), and high-risk ...
