Relationship between predicting bleeding complication in patients undergoing stent implantation and subsequent dual antiplatelet therapy (PRECISE-DAPT) score and mortality among patients with atrial fibrillation undergoing percutaneous coronary intervention

External validity of the PRECISE-DAPT score in patients undergoing PCI: a systematic review and meta-analysis

AIMS

To summarize the totality of evidence validating the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score, ascertaining its aggregate discrimination and validation power in multiple population subsets.

METHODS AND RESULTS

We searched electronic databases from 2017 (PRECISE-DAPT proposal) up to March 2023 for studies that reported the occurrence of out-of-hospital bleedings according to the PRECISE-DAPT score in patients receiving DAPT following percutaneous coronary intervention (PCI). Pooled odds ratios (OR) with 95% confidence interval (CI) were used as summary statistics and were calculated using a random-effects model. Primary and secondary endpoints were the occurrence of any and major bleeding, respectively. A total of 21 studies and 67 283 patients were included; 24.7% of patients (N = 16 603) were at high bleeding risk (PRECISE-DAPT score ≥25), and when compared to those at low bleeding risk, they experienced a significantly higher rate of any out-of-hospital bleeding (OR: 2.71; 95% CI: 2.24-3.29; P-value <0.001) and major bleedings (OR: 3.51; 95% CI: 2.71-4.55; P-value <0.001). Pooling data on c-stat whenever available, the PRECISE-DAPT score showed a moderate discriminative power in predicting major bleeding events at 1 year (pooled c-stat: 0.71; 95% CI: 0.64-0.77).

CONCLUSION

This systematic review and meta-analysis confirms the external validity of the PRECISE-DAPT score in predicting out-of-hospital bleeding outcomes in patients on DAPT following PCI. The moderate discriminative ability highlights the need for future improved risk prediction tools in the field.

The PRECISE-DAPT score and 5-year outcomes after percutaneous coronary intervention: a large-scale, real-world study from China

AIMS

The PRECISE-DAPT (predicting bleeding complications in patients undergoing stent implantation and subsequent dual-antiplatelet therapy) score is recommended by guidelines for predicting out-of-hospital bleeding in patients after percutaneous coronary intervention (PCI). However, the long-term prognostic value of the PRECISE-DAPT score in patients after PCI remains unclear.

METHODS AND RESULTS

We performed a prospective study of 10 724 patients who underwent PCI throughout 2013 in Fuwai Hospital. The bleeding endpoint was Bleeding Academic Research Consortium 2, 3, or 5 bleeding. The ischaemic endpoints were all-cause death and major adverse cardiovascular and cerebrovascular events (MACCE). After a 5-year follow-up, 10 109 patients were finally analysed. A total of 415 (4.11%) patients experienced bleeding, 364 (3.60%) experienced all-cause death, and 2049 (20.27%) had MACCE. Using Cox regression, the risks of bleeding [hazard ratio (HR): 1.721, 95% confidence interval (CI): 1.180-2.511, P = 0.005], MACCE (HR: 1.607, 95% CI: 1.347-1.917, P < 0.001), and all-cause-death (HR: 3.902, 95% CI: 2.916-5.221, P < 0.001) in patients with a high score were significantly higher than those in patients with a low score. The PRECISE-DAPT score showed prognostic value for 5-year events of bleeding (C-statistic: 0.566, 95% CI: 0.537-0.594), MACCE (C-statistic: 0.540, 95% CI: 0.527-0.553), and all-cause death (C-statistic: 0.673, 95% CI: 0.644-0.702).

CONCLUSION

After 5 years of follow-up, the PRECISE-DAPT score has a statistically significant predictive value for long-term bleeding events in the Chinese PCI population, and also some prognostic value for death and MACCE.

ONE-SENTENCE SUMMARY

In this real-world, large-sample study, the PRECISE-DAPT (predicting bleeding complications in patients undergoing stent implantation and subsequent dual-antiplatelet therapy) score shows a statistically significant 5-year predictive value for bleeding in Chinese patients with percutaneous coronary intervention and dual-antiplatelet therapy. The study also shows that the PRECISE-DAPT score has moderate predictive value for all-cause death.
