Meta-Analysis: 1-Month Dual Antiplatelet Therapy Reduces Major Bleeding Without Increasing Stent Thrombosis After PCI with DES – Am J Cardiol

Main Findings: The analysis found that 1-month DAPT significantly reduced the risk of major bleeding (OR 0.66, 95% CI 0.45-0.97, p = 0.03) compared to >1-month DAPT. Additionally, there was no significant difference in stent thrombosis rates between the groups (OR 1.08, 95% CI 0.81-1.44, p = 0.60). Secondary outcomes, including all-cause mortality, cardiovascular death, myocardial infarction, stroke, and major adverse cardiovascular or cerebrovascular events were also similar between the groups.

Implications for Practice: The findings support the use of 1-month DAPT followed by aspirin or a P2Y12 receptor inhibitor as a safer alternative to longer-term DAPT in patients undergoing PCI with DES. This strategy may help reduce bleeding risks without increasing the likelihood of thrombotic events, making it a viable option for routine clinical practice, particularly in patients at high risk for bleeding.
