De-escalation to ticagrelor monotherapy versus 12 months of dual antiplatelet therapy in patients with and without acute coronary syndromes: a systematic review and individual patient-level meta-analysis of randomised trials
Abstract
BACKGROUND
Dual antiplatelet therapy (DAPT) for 12 months is the standard of care after coronary stenting in patients with acute coronary syndrome (ACS). The aim of this individual patient-level meta-analysis was to summarise the evidence comparing DAPT de-escalation to ticagrelor monotherapy versus continuing DAPT for 12 months after coronary drug-eluting stent implantation.
METHODS
A systematic review and individual patient data (IPD)-level meta-analysis of randomised trials with centrally adjudicated endpoints was performed to evaluate the comparative efficacy and safety of ticagrelor monotherapy (90 mg twice a day) after short-term DAPT (from 2 weeks to 3 months) versus 12-month DAPT in patients undergoing percutaneous coronary intervention with a coronary drug-eluting stent. Randomised trials comparing P2Y12 inhibitor monotherapy with DAPT after coronary revascularisation were searched in Ovid MEDLINE, Embase, and two websites (www.tctmd.com and www.escardio.org) from database inception up to May 20, 2024. Trials that included patients with an indication for long-term oral anticoagulants were excluded. The risk of bias was assessed using the revised Cochrane risk-of-bias tool. The principal investigators of the eligible trials provided IPD by means of an anonymised electronic dataset. The three ranked coprimary endpoints were major adverse cardiovascular or cerebrovascular events (MACCE; a composite of all-cause death, myocardial infarction, or stroke) tested for…
