Insights
The PRECISE-DAPT score
Area of Science:
- Cardiology
- Clinical Research
- Predictive Analytics
Background:
- The PRECISE-DAPT score predicts bleeding risk after percutaneous coronary intervention (PCI).
- Its predictive ability may change over time and differ between sexes.
- Understanding these dynamics is crucial for patient management.
Purpose of the Study:
- To compare the predictive performance of the PRECISE-DAPT score at baseline versus during follow-up in male and female patients after PCI.
- To assess how the score's ability to predict bleeding events evolves over time.
Main Methods:
- Prospective, multicenter RE-SCORE registry.
- Inclusion of 480 patients undergoing PCI and treated with 1-year dual antiplatelet therapy (DAPT).
- Calculation of PRECISE-DAPT score at baseline and at 1, 4, and 8-month follow-ups.
Main Results:
- Baseline PRECISE-DAPT scores were similar between males and females.
- Increases in PRECISE-DAPT scores were significantly more frequent in females (44%) than males (23%).
- Follow-up reassessment showed excellent bleeding prediction in females (c-index=0.84) but modest prediction in males (c-index=0.61).
Conclusions:
- The bleeding predictive ability of the PRECISE-DAPT score varies over time, particularly in females.
- Reassessing the PRECISE-DAPT score during follow-up improves its discriminative ability in females, while remaining modest in males.
- Sex-specific monitoring of bleeding risk post-PCI is warranted.
Abstract:
The risk of bleeding as predicted by the PRECISE-DAPT score can vary over time after percutaneous coronary intervention (PCI). We sought to compare the predictive ability of the PRECISE-DAPT score calculated at baseline and reassessed during follow-up in male and female patients undergoing PCI. The RE-SCORE was a multicenter, prospective registry including patients undergoing PCI treated with dual antiplatelet therapy (DAPT) for 1 year. The primary endpoint was Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding. The PRECISE-DAPT score was determined for each patient at the time of PCI and at 1, 4 and 8-month follow-up visits or before the occurrence of an endpoint event. A total of 480 patients undergoing PCI were included. At baseline, median PRECISE-DAPT score was similar in males (23.2 [IQR 20.1-24.2]) and females (23.4 [IQR 20.2-25.3]; p = .22). During follow-up, an increase in the PRECISE-DAPT occurred significantly more often in females (44%) than in males (23%; p < .001). The discrimination of the PRECISE-DAPT score calculated at baseline was marginal in both males (c-index = 0.59, 95% CI: 0.51-0.65) and females (c-index = 0.55, 95% CI: 0.49-0.60). The discriminative ability of the score reassessed at follow-up was excellent in females (c-index = 0.84; 95% CI: 0.77-0.91) but remained modest in males (c-index = 0.61; 95% CI: 0.55-0.70). The bleeding predictive ability of the PRECISE-DAPT score can vary over time, more commonly in females than males. The discrimination of the score calculated during follow-up appeared improved in females but remained modest in males.Clinical Trial Registration - ClinicalTrials.gov Identifier: NCT03526614.
