Abstract:
We assessed the association of prior antiplatelet therapy (APT) at onset of intracerebral haemorrhage (ICH) with haematoma characteristics and outcome. Methods We performed a systematic review and meta-analysis of studies comparing ICH outcomes of patients on APT (APT-ICH) with patients not taking APT (non–APT-ICH). Primary outcomes were haematoma volume (mean difference and 95% CI), haematoma expansion (HE), in-hospital 3-month mortality rates and good functional outcome (modified Rankin Scale score 0–2). We provide odds ratios (ORs) from random effects models and subgroup analyses for haematoma expansion and short-term mortality rates. Results We included 23 of 1551 studies on 30,949 patients with APT-ICH and 62,018 with non-APT-ICH. Patients on APT were older (Δmean 6.27 years, 95% CI 5.44–7.10), had larger haematoma volume (Δmean 5.74 mL, 95% CI 1.93–9.54), higher short-term mortality rates (OR 1.44, 95% CI 1.14–1.82), 3-month mortality rates (OR 1.58, 95% CI 1.14–2.19) and lower probability of good functional outcome (OR 0.61, 95% CI 0.49–0.77). While there was no difference in HE in the overall analysis (OR 1.32, 95% CI 0.85–2.06), HE occurred more frequently when assessed within 24 h (OR 2.58, 95% CI 1.18–5.67). We found insufficient data for comparison of single versus dual APT-ICH. Heterogeneity was substantial amongst studies. Discussion APT is associated with larger baseline haematoma volume, early ( 〈 24 h) haematoma expansion, mortality rates and morbidity in patients with ICH. Data on differences in single and dual APT-ICH are scarce and warrant further investigation. New treatment options for APT-ICH are urgently needed.
