Abstract

Purpose

To assess the efficacy and safety of low-dose prasugrel compared to clopidogrel based on the occurrence of major adverse cardiac events (MACEs) and major bleeding in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI).

Methods

The PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were systematically searched up to May 2020 to identify relevant randomized controlled trials (RCTs) and observational studies. A meta-analysis was conducted using a random effects model to estimate relative risks (RRs) with 95% confidence intervals (CIs). The primary efficacy and safety endpoints were MACE and major bleeding, respectively.

Results

Three RCTs (n = 2884) and five observational studies (n = 30,117) were included. A meta-analysis of RCTs revealed no significant differences in terms of MACE (RR 0.92, 95% CI 0.74 to 1.16) or major bleeding (RR 0.97, 95% CI 0.57 to 1.65) between low-dose prasugrel and clopidogrel. A meta-analysis of observational studies revealed no significant difference in terms of MACE (RR 1.13, 95% CI 0.82 to 1.55) between the two groups, but low-dose prasugrel was associated with a significantly increased risk of major bleeding (RR 1.33, 95% CI 1.02 to 1.72).

Conclusions

We found that low-dose prasugrel was not associated with changes in MACE or major bleeding compared with clopidogrel in RCTs. However, analysis of data from observational studies revealed that low-dose prasugrel was associated with an increased risk of major bleeding compared with clopidogrel.
