Description
Summary:<b>Background:</b> Intracerebral hemorrhage management presents clinicians with a significant therapeutic challenge. Maintaining antiplatelet therapy potentially increases the risk of recurrent bleeding, while discontinuation heightens susceptibility to ischemic stroke, particularly during the critical first month after hemorrhage. In contemporary practice, physicians demonstrate considerable hesitancy regarding early antiplatelet reinitiation, complicated by the absence of clear evidence-based treatment guidelines. <b>Aim:</b> This meta-analysis assesses the safety of early antiplatelet resumption following ICH. <b>Methods</b>: We conducted a systematic review by searching Web of Science, Scopus, PubMed, and Cochrane Library from inception to April 2025. Articles were independently screened and data extracted by two reviewers who also assessed study quality. The inclusion criteria are enrollment of adults (≥18 years) with imaging-confirmed intracerebral hemorrhage surviving >24 h, comparing early vs. delayed or withheld antiplatelet therapy. Randomized trials underwent separate evaluation using Cochrane’s Risk of Bias. Statistical analysis was performed using R software (version 4.4.2), with categorical outcomes pooled as risk ratios (RRs) with 95% confidence intervals. Statistical significance was established at <i>p</i> < 0.05. The evidence is limited by the availability of few RCTs, variable antiplatelet regiments, male predominance, and other confounding factors. The review was registered in SFO. <b>Results:</b> Our meta-analysis included 10 studies (8 observational, 2 RCTs) with 5554 patients. Early antiplatelet therapy significantly reduced recurrent intracerebral hemorrhage by 46% (RR 0.54, 95% CI 0.37–0.78, <i>p</i> = 0.001). All-cause mortality showed a non-significant difference (RR 0.81, 95% CI 0.65–1.01, <i>p</i> = 0.06). No significant differences were found for ischemic stroke (RR 0.99, 95% CI 0.60–1.63, <i>p</i> = 0.96), major hemorrhagic events (RR 0.75, 95% CI 0.49–1.13, <i>p</i> = 0.17), or ischemic vascular outcomes (RR 0.71, 95% CI 0.49–1.02, <i>p</i> = 0.60). <b>Conclusions:</b> Our meta-analysis reveals that early antiplatelet therapy following intracerebral hemorrhage significantly reduces recurrent hemorrhagic events (46% reduction) without increasing major ischemic or hemorrhagic complications.
