The PARIS risk score showed similar discrimination to PRECISE-DAPT for 1-year BARC 2, 3, or 5 bleeding (c-statistic 0.63 vs 0.61; p=0.29) but provided a higher net benefit in decision curve analyses.

Does the PARIS risk score outperform the PRECISE-DAPT risk score for predicting one-year out-of-hospital bleeding in ACS patients treated with PCI and DAPT?
Both PARIS and PRECISE-DAPT risk scores are moderately effective for predicting one-year bleeding in ACS patients on DAPT, with PARIS showing a higher net benefit in risk classification.

AIMS: The PRECISE-DAPT and PARIS risk scores (RSs) were recently developed for bleeding risk assessment in percutaneous coronary intervention (PCI) patients treated with dual antiplatelet therapy (DAPT). We aimed to assess the performance of these RSs for predicting out-of-hospital bleeding in patients with acute coronary syndrome (ACS). METHODS AND RESULTS: Retrospectively, we studied 1,926 consecutive ACS patients treated with PCI and DAPT. The performance of RSs for predicting one-year BARC type 2, 3 or 5 bleeding and BARC type 3 or 5 bleeding was assessed and compared. Both RSs were effective for the prediction of bleeding events. For BARC type 2, 3 or 5 bleeding, the c-statistic values for PRECISE-DAPT and PARIS were 0.61 and 0.63 (p=0.29), respectively. The two scores displayed equal c-statistics of 0.73 for predicting BARC type 3 or 5 bleeding. PARIS significantly outperformed PRECISE-DAPT in terms of indices of categoryless net reclassification improvement and integrated discrimination. Decision curve analyses also favoured PARIS. CONCLUSIONS: Within our cohort, PARIS and PRECISE-DAPT were fairly to moderately effective for the prediction of bleeding. Their predictiveness varies according to the bleeding severity. PARIS-derived bleeding risk assessment was associated with a higher net benefit compared to PRECISE-DAPT-based bleeding risk assessment.
Abu‐Assi et al. (Thu,) conducted a cohort in acute coronary syndrome (n=1,926). PARIS risk score vs. PRECISE-DAPT risk score was evaluated on One-year BARC type 2, 3 or 5 bleeding (c-statistic 0.63 vs 0.61, p=0.29). The PARIS risk score showed similar discrimination to PRECISE-DAPT for 1-year BARC 2, 3, or 5 bleeding (c-statistic 0.63 vs 0.61; p=0.29) but provided a higher net benefit in decision curve analyses.
