- Abstract
Background: Intravenous thrombolysis (IVT), which is safe and effective, is the first‐line therapy for acute ischemic stroke (AIS). However, its benefit for AIS patients with pre‐stroke disability (PSD) is controversial. Objective: We determined the association of PSD with the safety and efficacy of IVT among patients with AIS. Methods: We searched PubMed, Embase, and the Cochrane Library from inception to May 23, 2022. The articles focusing on outcomes of AIS patients with PSD receiving IVT were retrieved. We used the random‐effects model to pool outcomes including mortality, 24 h NIHSS improvement, symptomatic intracerebral hemorrhage (sICH), favorable functional outcome (FFO), the favorable outcome, and mortality prevalence. Results: Ten studies (including 245,773 participants) that reported the outcomes of AIS patients with PSD undergoing IVT were included. In unadjusted analyses, PSD was associated with mortality (10 studies; odds ratio [OR] 1.739, 95% confidence interval [CI], 1.336–2.407), FFO (7 studies; OR 1.057, 95% CI, 1.015–1.100), 24 h NIHSS improvement (5 studies; OR.840, 95% CI,.819–.917, p =.000), and sICH (9 studies; OR.773, 95% CI,.481–1.243). In adjusted analyses, PSD was associated with mortality (seven studies; ORadj 1.789, 95% CI, 1.413–2.264), FFO (five studies; ORadj 1.087, 95% CI, 1.002–1.179), 24 h NIHSS improvement (five studies; ORadj.837, 95% CI,.799–.876), and sICH (five studies; ORadj.857, 95% CI,.725–1.012). The prevalence of FFO and mortality in patients with pre‐stroke modified Rankin Scale scores of 2–5 were 49% (0.42–0.56) and 37% (0.21–0.53), respectively. Conclusions: Patients with PSD undergoing IVT had a higher mortality rate than those without PSD. Meanwhile, PSD was associated with FFO, and there was no significant difference in sICH and 24 h NIHSS improvement. High‐quality data are needed to clarify the benefits of administering IVT in these patients.
