The Predictive Value of Barthel Score, Sequential Organ Failure Assessment Score, and D-Dimer in the 28-Day Prognosis of Patients with Non-ST Elevation Myocardial Infarction: A Retrospective Study of 358 Patients.

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 (< 0.05). The results showed that D-dimer (= 0.002), SOFA score (= 0.017), BI score (< 0.001), and chest pain symptoms (< 0.001) were independent predictors of 28-day death. When chest pain symptoms (AUC = 0.585), D-dimer (AUC = 0.945, = 8.00, < 0.01), BI score (AUC = 0.145, = 5.36, < 0.01), and SOFA score (AUC = 0.847, = 4.93, < 0.01) were compared, the results showed that BI score (HR = 0.961, < 0.01) and SOFA score (HR = 1.316, < 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.
