INTRODUCTION: Clinical data on short mandatory dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy, compared with prolonged DAPT in patients undergoing percutaneous coronary intervention (PCI) are insufficient. We aim to evaluate the effectiveness and safety of P2Y12 inhibitor monotherapy and prolonged DAPT after short mandatory DAPT on cardiovascular events in patients undergoing PCI.
EVIDENCE ACQUISITION: A systematic literature search was performed in seven medical databases from building the database until July 2019. Three studies with randomized controlled trial (RCTs), totaling 21,970 patients, were included in this meta-analysis. The included studies were assessed by the Cochrane risk of bias and analyzed by Review Manager v. 5.3 software.
EVIDENCE SYNTHESIS: Our result of pooled analysis showed that there was noninferior rates of in major adverse cardiac and cerebrovascular events (MACCE), stroke, myocardial infarction and cardiac death between short mandatory DAPT followed by P2Y12 inhibitor monotherapy and prolonged DAPT in patients undergoing PCI. Pooled analysis showed that short mandatory DAPT followed by P2Y12 inhibitor monotherapy could significantly reduce the risk of bleeding BARC type 2-5 (OR=0.47, 95% CI: 0.31-0.70, P=0.002), compared with prolonged DAPT in patients undergoing PCI. However, Pooled analysis showed that short mandatory DAPT followed by P2Y12 inhibitor monotherapy was not associated with BARC type 3-5, compared with prolonged DAPT.
CONCLUSIONS: This meta-analysis demonstrated that short mandatory DAPT followed by P2Y12 inhibitor monotherapy compared with prolonged DAPT resulted in noninferior rates of MACCE, all-cause mortality, cardiac death, stroke, myocardial infarction and stent thrombosis. Furthermore, short mandatory DAPT followed by P2Y12 inhibitor monotherapy could significantly reduce the risk of bleeding BARC type 2-5.
