Abstract

Introduction and aim: The optimal composition and duration of antiplatelet therapy after complex percutaneous coronary intervention (PCI) remains unclear. We conducted a meta-analysis to compare 1-3 months of dual antiplatelet therapy (DAPT) followed by monotherapy vs. 12 months of DAPT.

Method: MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were queried for studies comparing 1-3 months of DAPT followed by monotherapy vs. 12 months of DAPT in the outcomes of complex PCI from inception through January 2023. Outcomes of interest included major bleeding, all-cause mortality, cardiovascular mortality, myocardial infarction (MI), stent thrombosis, target vessel revascularization, and stroke.

Results: Compared to 12 months, 1-3 months of dual antiplatelet therapy had a weak association with less major bleeding (OR 0.67; 95 % CI, 0.44-1.00; p = 0.05; I2 = 28 %). There were no significant differences between the shorter and longer antiplatelet therapy in terms of all-cause mortality (OR 0.83; 95 % CI, 0.59-1.16; p = 0.21; I2 = 17 %), cardiovascular mortality (OR 0.87; 95 % CI, 0.53-0.42; p = 0.50; I2 = 0), MI (OR 0.97; 95 % CI, 0.69-1.35; p = 0.82; I2 = 32 %), stent thrombosis (OR 1.17, 95 % CI, 0.77-1.76; p = 0.38; I2 = 0 %), target vessel revascularization (OR 1.05, 95 % CI, 0.58-1.89; p = 0.82; I2 = 64 %), or stroke (OR 1.10, 95 % CI, 0.55-2.17; p = 0.37; I2 = 7 %);.

Conclusion: Among patients undergoing complex PCI, DAPT for 1-3 months may be associated with less major bleeding but similar rates of cardiovascular events (death, MI, stroke, stent thrombosis, and revascularization) compared to DAPT for 12 months.
