Comparative efficacy and safety of oral P2Y12 inhibitors for patients with chronic kidney disease and acute coronary syndrome: a network meta-analysis
Abstract
Background: Currently, there is a paucity of data concerning the safety and effectiveness of P2Y12 inhibitors in the acute coronary syndrome (ACS) with chronic kidney disease (CKD) population. The aim of this study is to compare the different oral P2Y12 inhibitors in terms of efficacy and safety, focusing exclusively on patients with CKD who were treated for ACS. Methods: We systematically searched PubMed, CENTRAL, and Web of Science to identify studies that compared different oral P2Y12 inhibitors (clopidogrel, prasugrel, and ticagrelor) in patients with ACS with CKD. Efficacy outcomes included the major adverse cardiovascular events composite outcome and safety outcomes included major bleedings and major or minor bleedings combined. We performed a frequentist network meta-analysis. Results: Twelve studies were included in the systematic review, 7 CKD subgroup analyses of RCTs (8878 patients) and 5 observational studies (20175 patients). After the exclusion of studies with conservative management, prasugrel resulted in significant primary endpoint reduction versus clopidogrel (HR 0.80 and 95% CI 0.64 - 0.99), while ticagrelor did not (HR 0.88 and 95% CI 0.73 - 1.06). Major bleedings did not differ between the interventions. Ticagrelor resulted in more major or minor bleedings than clopidogrel (HR 1.21 and 95% CI 1.06 - 1.38), whereas prasugrel did not (HR 1.12 and 95% CI 0.84 - 1.49). Conclusion: In patients with ACS with underlying CKD, who are intended to receive invasive management, there may be a significant reduction of the primary efficacy outcome with prasugrel as compared to clopidogrel but not with ticagrelor as compared to clopidogrel. There probably exists no difference among interventions in the major bleedings. Dedicated RCTs are needed to confirm these results.
