Benefits of short-term or prolonged as compared to standard 1  year DAPT in patients with acute coronary syndrome treated with drug-eluting stents: a meta-analysis of 9 randomized trials

AbstractOptimal timepoint for the discontinuation of dual antiplatelet therapy (DAPT) after an acute coronary syndrome is still debated. In fact, despite a shortening of DAPT duration should be advocated, based on the negligible risk of thrombotic complications observed with newer generations of drug-eluting stents (DES), in order to reduce the hemorrhagic risk, a more prolonged anti-ischemic protection would be suitable for certain higher-risk patients, rendering the traditional 12  months strategy outdated. We performed an updated meta-analysis and indirect comparison of randomized trials comparing shorter vs extended DAPT duration in ACS patients undergoing percutaneous coronary interventions with DES. Literature and main scientific session abstracts were searched for studi es comparing 3–6 (short-term) or prolonged (>  12 months) DAPT vs traditional 12 months in ACS patients treated with DES. The primary efficacy endpoint was mortality, primary safety endpoint was the occurrence of major bleedings. Secondary endpoints were myocardial infarction and stent thrombosis. We included three randomized clinical trial s and six study sub-analysis comparing alternative (short-term or prolonged) DAPT vs 12 months in post-ACS, with a total of 15,738 patients. Mortality occurred in 1.8% of patients, with no difference according to DAPT duration (short-term vs standard DAPT: OR [95% CI] 1.00 [0.72–1.39], p = 0. 99;>  12 vs 12 months: OR [95% CI] 0.87 [0.61–1.22...
