Purpose: To investigate the nursing prediction value of Barthel score, sequential organ failure assessment (SOFA) score and D-dimer on non-ST-elevation myocardial infarction (NSTEMI) inpatients.
Methods: The clinical data of 358 NSTEMI patients admitted to the emergency department were analyzed using logistic regression equation and a ROC curve was drawn. The area under ROC curve (AUC) of different indicators was compared. A COX regression model was created, and a survival curve was drawn.
Results: There were significant differences in age, D-dimer, WBC, NT-proBNP, EF (%), BI score, MEWS score, and SOFA score between the 28-day death group and the survival group (P <  0.05). The results showed that D-dimer (P =  0.002), SOFA score (P =  0.017), BI score (P <  0.001), and chest pain symptoms (P <  0.001) were independent predictors of 28-day death. When chest pain symptoms (AUC =  0.585), D-dimer (AUC =  0.945, Z =  8.00, P <  0.01), BI score (AUC =  0.145, Z =  5.36, P <  0.01), and SOFA score (AUC =  0.847, Z =  4.93, P <  0.01) were compared, the results showed that BI score (HR =  0.961, P <  0.01) and SOFA score (HR =  1.316, P <  0.001) had statistical significance on the 28-day survival time of the dead patients.
Conclusion: The Barthel score, SOFA score, and D-dimer are all essential in predicting the severity of NSTEMI patients, with a high nursing evaluation value. The Barthel and SOFA scores are associated with the risk of death within 28 days.
