Terapia antitrombotica ottimale per i pazienti con ictus ischemico e fibrillazione atriale e malattia cardiovascolare aterosclerotica: una meta-analisi di rete frequentista.

BACKGROUND: The optimal antithrombotic strategy for secondary prevention in patients with atrial fibrillation (AF) and concomitant atherosclerotic cardiovascular disease (ASCVD) following acute ischemic stroke (IS) remains undefined. This network meta-analysis aimed to compare the efficacy and safety of oral anticoagulant (OAC) monotherapy, antiplatelet therapy (APT), and their combination in this population. METHODS: We systematically searched major electronic databases through October 2025 for relevant randomized and non-randomized studies. A frequentist network meta-analysis was performed using random-effects models to calculate pooled hazard ratios (HRs) with 95% confidence intervals (C
