Background
Besides its primary clinical utility in predicting bleeding risk in patients with acute coronary syndrome (ACS), the PRECISE-DAPT (Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Anti-Platelet Therapy) score may also be useful for predicting long-term mortality in ACS patients presenting with cardiogenic shock (CS) since several studies have reported an association between the score and certain cardiovascular conditions or events. The aim of the present study was to evaluate the utility of the PRECISE-DAPT score for predicting the long-term all-cause mortality in patients (n = 293) with ACS presenting with CS.
Methods
The PRECISE-DAPT score was calculated for each patient who survived in hospital, and the association with long-term mortality was studied. Median follow-up time was 2.7 years. The performance of the final model was determined with measurements of its discriminative power (Harrell’s and Uno’s C indices and time-dependent area under the receiver operating characteristic curve [AUC]) and predictive accuracy (coefficient of determination [R2] and likelihood ratio χ2). Hazard ratios (HRs) were used to assess the relationship between the variables of the model and long-term all-cause death.
Results
All-cause death occurred in 197 patients (67%). There was a positive association between the PRECISE-DAPT score (change from 17 to 38 was associated with an HR of 2.42 [95% CI: 1.59–3.68], R2 = 0.209, time-dependent AUC = 0.69) and the risk of death such that in the adjusted survival curve, the risk of mortality increased as the PRECISE-DAPT score increased.
Conclusion
The PRECISE-DAPT score may be a useful easy-to-use tool for predicting long-term mortality in patients with ACS complicated by CS.
