The aim of this study was to investigate the predictive ability of PiCCO hemodynamic parameters and the relative contribution features based on the XGBoost model.  \nMethods: Multi-class receiver operating characteristic (ROC) curves explored that the XGBoost prediction model performed extremely well about LVEF and NT-proBNP. Further SHapley Additive explanation (SHAP) value analysis revealed the contributions of different PiCCO hemodynamic parameters.  \nResults: Features such as CI (cardiac index), CPI (cardiac power index), and SVRI (systemic vascular resistance index) showed significant positive effects on the prediction of LVEF and NT-proBNP. In terms of MACE, dPmax (index of the left ventricular contractility), CFI (cardiac function index), and GEDVI (global enddiastolic volume index) showed significant predictive value.  \nDiscussion: Overall, XGBoost machine learning model based on PiCCOhemodynamic parameters provide evidence that effectively predict key clinical prognostic indicators in the patients with cardiogenic shock. These results provide important theoretical basis for further individualized clinical decisionmaking in cardiogenic shock patients.  \nKEYWORDS  \nXGBoost machine learning model, pulse index continuous cardiac output, left ventricular ejection fraction, N-terminal pro-brain natriuretic peptide, major adverse cardiovascular events  \n1 Introduction  \nCardiogenic shock is a critical condition characterized by cardiac dysfunction resulting inan inadequate cardiac output ( 1–3). It is associated with substantial morbidity and mortality (2–4). Despite significant advances in etiological treatment, pharmacological therapy, and mechanical circulatory support, the diagnosis and treatment of cardiogenic shock continue to present formidable clinical challenges.  \nPrevious studies have mainly guided the management","cbCaiapqxb2BhW9z","https://ap.wps.com/l/cbCaiapqxb2BhW9z","pdf",2180015,6,1,11,"English","en",105,"# Introduction\n## Cardiogenic shock challenges and need for dynamic assessment\n## PiCCO monitoring and advantages\n# Methods\n## XGBoost modeling and evaluation strategy\n## ROC analysis and SHAP interpretability\n# Results\n## Predictive performance for LVEF and NT-proBNP\n## Feature contributions for LVEF/NT-proBNP and MACE\n# Discussion\n## Implications for prognostic prediction and individualized decision-making","[{\"question\":\"What does the study predict using PiCCO hemodynamic parameters?\",\"answer\":\"The XGBoost model predicts left ventricular ejection fraction (LVEF), N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, and 30-day major adverse cardiovascular events (MACE) in patients with cardiogenic shock.\"},{\"question\":\"How is the prediction model evaluated in this research?\",\"answer\":\"Multiclass receiver operating characteristic (ROC) curves are used to assess how well the XGBoost model performs for LVEF and NT-proBNP, and SHAP value analysis is applied to interpret feature contributions.\"},{\"question\":\"Which PiCCO features show significant predictive effects according to the results?\",\"answer\":\"For LVEF and NT-proBNP, CI, CPI, and SVRI show significant positive effects.
