In patients with chronic coronary syndrome requiring long-term oral anticoagulation, OAC monotherapy reduced bleeding, cardiovascular death, and net adverse clinical events compared with OAC plus SAPT.
Meta-Analysis
Does OAC monotherapy improve safety and efficacy compared with OAC plus SAPT in patients with CCS requiring long-term OAC?
In patients with chronic coronary syndrome requiring long-term anticoagulation, OAC monotherapy reduces bleeding and cardiovascular death compared to OAC plus single antiplatelet therapy without increasing ischemic events.
BACKGROUND: The optimal antithrombotic therapy for patients with chronic coronary syndrome (CCS) who also require long-term oral anticoagulation (OAC) remains uncertain. OBJECTIVES: The aim of this study was to evaluate the safety and efficacy of OAC monotherapy compared with OAC plus single antiplatelet therapy (SAPT) in CCS patients with an indication for long-term anticoagulation. METHODS: Randomized trials comparing OAC monotherapy with OAC plus SAPT in patients with CCS and indication for long-term OAC from the PubMed, Cochrane Central, Web of Science, and Scopus databases up to November 10, 2025 were included in this systematic review and meta-analysis. HRs and 95% CIs were estimated through a random-effects meta-analytical framework. The primary efficacy endpoint was trial-defined major adverse cardiovascular events, and the primary safety endpoint was any bleeding. RESULTS: =47%) compared with OAC plus SAPT. There were no significant differences in myocardial infarction, stroke, or all-cause mortality. CONCLUSIONS: In patients with CCS requiring long-term OAC, OAC monotherapy was associated with reduced bleeding, cardiovascular death, and net adverse clinical events compared with OAC plus SAPT.

Galli et al. (Fri,) conducted a meta-analysis in Chronic coronary syndrome requiring long-term oral anticoagulation. Oral anticoagulation (OAC) monotherapy vs. OAC plus single antiplatelet therapy (SAPT) was evaluated on Trial-defined major adverse cardiovascular events (efficacy) and any bleeding (safety). In patients with chronic coronary syndrome requiring long-term oral anticoagulation, OAC monotherapy reduced bleeding, cardiovascular death, and net adverse clinical events compared with OAC plus SAPT.
