The association of PRECISE-DAPT score with ischaemic outcomes in patients taking dual antiplatelet therapy following percutaneous coronary intervention: a meta-analysis

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.

Bleeding risk and P2Y12 inhibitors in all-comer patients with ST-segment elevation myocardial infarction treated with percutaneous coronary intervention: a single-centre cohort study

AIMS

To characterize and follow patients with ST-segment elevation myocardial infarction (STEMI) at high bleeding risk (HBR) according to the predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy (PRECISE-DAPT) score, and to examine the use of P2Y12 inhibitors and the subsequent risk of major adverse cardiovascular events (MACE) and bleeding.

METHODS AND RESULTS

This single-centre cohort study included 6179 consecutive STEMI patients who underwent percutaneous coronary intervention (PCI) at Copenhagen University Hospital, Rigshospitalet, between 2009 and 2016. Individual linkage to nationwide registries was conducted to obtain information on diagnoses, claimed drugs, and vital status. Of the 5532 (89.5%) patients with available PRECISE-DAPT scores, 33.0% were at HBR and more often elderly and female with more comorbidities than non-HBR patients. One-year cumulative incidence rates per 100 person-years were 8.7 and 2.1 for major bleeding and 36.8 and 8.3 for MACE in HBR and non-HBR patients, respectively. Among the 4749 (85.8%) patients who survived and collected a P2Y12 inhibitor ≤7 days from discharge, 68.2% of HBR patients were treated with ticagrelor or prasugrel and 31.8% with clopidogrel, while 18.2% non-HBR patients were treated with clopidogrel. Adherence was high for all (>75% days coverage). The risk of MACE was lower in ticagrelor- and prasugrel-treated patients than in clopidogrel-treated patients without differences in major bleeding.

CONCLUSION

One-third of PCI-treated all-comer patients with STEMI were at HBR according to the PRECISE-DAPT score and were more often treated with potent P2Y12 inhibitors instead of clopidogrel. Thus, ischaemic risk may be weighted over bleeding risk in STEMI patients at HBR.

Management of Residual Risk in Chronic Coronary Syndromes. Clinical Pathways for a Quality-Based Secondary Prevention

Chronic coronary syndrome (CCS), which encompasses a broad spectrum of clinical presentations of coronary artery disease (CAD), is the leading cause of morbidity and mortality worldwide. Recent guidelines for the management of CCS emphasize the dynamic nature of the CAD process, replacing the term "stable" with "chronic", as this disease is never truly "stable". Despite significant advances in the treatment of CAD, patients with CCS remain at an elevated risk of major cardiovascular events (MACE) due to the so-called residual cardiovascular risk. Several pathogenetic pathways (thrombotic, inflammatory, metabolic, and procedural) may distinctly contribute to the residual risk in individual patients and represent a potential target for newer preventive treatments. Identifying the level and type of residual cardiovascular risk is essential for selecting the most appropriate diagnostic tests and follow-up procedures. In addition, new management strategies and healthcare models could further support available treatments and lead to important prognostic benefits. This review aims to provide an overview of the diagnostic and therapeutic challenges in the management of patients with CCS and to promote more effective multidisciplinary care.
