Reperfusion therapies, such as intravenous thrombolysis and mechanical thrombectomy, are crucial for restoring cerebral blood flow but may also trigger ischemia– reperfusion injury and systemic inflammatory activation, associated with poorer clinical outcomes. Methods: We retrospectively analyzed medical records of 8833 patients hospitalized for acute ischemic stroke between January 2014 and May 2025 . Of these, 2242 (25.38%) underwent reperfusion therapy (mechanical thrombectomy ± intravenous thrombolysis), and 6591 (74.62%) were treated conservatively. Laboratory parameters, including leukocyte count, C-reactive protein (CRP), and albumin, and composite inflammatory indices (e.g., neutrophil-to-lymphocyte ratio (NLR), systemic immune–inflammation index (SII), systemic-inflammation response index (SIRI), and neutrophil percentage-to-albumin ratio (NPAR)), were assessed at admission. Clinical outcomes included in-hospital mortality and functional scale results (e.g., National Institutes of Health Stroke Scale, modified Rankin score (mRS), Barthel scale, and Glasgow Coma Scale (GCS)) . Results: Patients treated with reperfusion therapy had higher inflammatory indices (white blood cells, CRP, NLR, SII, and NPAR) compared to patients treated conservatively. In multiple regression analysis, these indices were significantly determined only by GCS and mRS scores, but age, gender, comorbidities, biochemical determinations, and type of ischemic stroke treatment (reperfusion or conservative) remained non-statistically significant. Conclusions: Patients with acute ischemic stroke undergoing reperfusion therapy exhibited a stronger inflammatory response and higher in-hospital mortality than those treated conservatively. However, multivariate analysis showed that a stronger","cbCaibEFqF7J1szb","https://ap.wps.com/l/cbCaibEFqF7J1szb","pdf",270866,15,"English","# Abstract\n## Methods\n## Results\n## Conclusions\n# 1.
