Abstract
OLANO, Ricardo D. et al. Artificial Intelligence Modeling with Non-Invasive Hemodynamics to Predict Preeclampsia in High-Risk Pregnancy. Rev. argent. cardiol. [online]. 2023, vol.91, n.5, pp.345-351. ISSN 1850-3748. http://dx.doi.org/10.7775/rac.es.v91.i5.20665.
Background:
Preeclampsia (PE) is the main cause of maternal-fetal morbidity and mortality in our country. Early hemodynamic changes during pregnancy could predict progression to PE. Machine learning (ML) enables the discovery of hidden patterns that could early detect PE development.
Objectives:
The aim of this study was to build a classification tree with non-invasive hemodynamic variables for the early prediction of PE occurrence.
Results:
Seventeen patients (15.18%) presented PE. A predictive classification tree was generated with arterial compliance index (ACI), cardiac index (CI), cardiac work index (CWI), ejective time ratio (ETR), and Heather index (HI). A total of 93.75% patients were correctly classified (Kappa 0.70, positive predictive value 0.94 and negative predictive value 0.35; accuracy 0.94, and area under the ROC curve 0.93).
Conclusion:
ACI, CI, CWI, ETR and HI variables predicted the early development of PE in our sample with excellent discrimination and accuracy, non-invasively, safely and at low cost.
