Aims: This study aimed to investigate the efficacy of early intensive statin therapy following intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS).
Methods: AIS patients who received IVT and statin therapy were included from multicenter registry databases. The primary endpoint was functional independence, defined by a modified Rankin Scale (mRS) score of 0-2 at 90 days. Propensity score matching (PSM) analyses were employed.
Results: A total of 21,349 patients were included in this study, with a mean age of 68.5 ± 12.6 years, of whom 13,578 (63.6%) were male. The baseline NIHSS score was 4 (IQR 2-8). A total of 9532 patients (44.6%) received intensive statin therapy. In the PSM analysis, the proportion of patients with mRS scores of 0-2 was significantly higher in the intensive statin therapy group (OR = 1.095, 95% CI 1.022-1.173, p = 0.010). Statin type modified the effect of intensive statin therapy on functional independence (p-value for interaction = 0.030). Treatment effects favoring the intensive approach were observed in patients receiving atorvastatin (OR = 1.134, 95% CI 1.051-1.224, p = 0.001).
Conclusion: Early intensive statin therapy following IVT leads to a significant but modest improvement in neurological outcomes, particularly in patients treated with atorvastatin as part of the intensive regimen.
