cases)and the death group(72 cases)according to their 30⁃day survival status after ECMO initiation. Baseline characteristics,treatment
⁃related data,and maximum vasoactive⁃inotropic score within 24 hours and 72 hours after cannulation(VISmax24 h,VISmax72 h)were
collected and compared between the two groups. Multivariate logistic regression was performed to establish the prediction model. The
area under the receiver operating characteristic curve,calibration curve,and decision⁃curve analysis(DCA)were used to evaluate
discrimination,calibration,and clinical utility of the model,and internal validation was conducted via the Bootstrap method. Results:
A total of 118 ECPR patients were included,and the 30 ⁃ day mortality rate was 61.0%(72/118). Multivariate logistic regression
demonstrated that acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score(OR=1.260,95%CI:1.064-1.492,P=0.007),
coronary heart disease(CHD)(OR=7.464,95%CI:1.284-43.386,P=0.025),continuous renal replacement therapy(CRRT)(OR=
4.146,95%CI:1.400-12.275,P=0.010),and VISmax72 h(OR=1.083,95%CI:1.018-1.153,P=0.012)were independent risk factors,
whereas delta cardiac troponin⁃T between day 1 and day 3 after cannulation(ΔcTnT)(OR=0.050,P=0.048)served as an independent
protective factor. The prediction model incorporating the above five variables yielded an area under the curve of 0.836(95%CI:0.765-
0.907). The calibration curve showed high consistency between model ⁃ predicted probabilities and actual observed probabilities.
Decision curve analysis indicated favorable clinical net benefit of the model. The C⁃index after Bootstrap internal validation reached
0.891. Conclusion:The prediction model integrating APACHE Ⅱ score,CHD,CRRT,ΔcTnT,and VISmax72 h exhibits satisfactory
predictive performance for 30⁃day mortality risk in adult ECPR patients surviving ≥72 h after ECMO cannulation. Integrating three
dimensions including baseline disease severity,organ injury and dynamic hemodynamic recovery,this model provides a quantitative
tool for early clinical risk stratification,therapeutic adjustment and doctor⁃patient communication.
