Abstract: OBJECTIVE:This study aimed to evaluate the prognostic significance of serum inflammatory factor levels in patients with acute ischemic stroke undergoing revascularization therapy. METHODS:The study included 94 patients with acute ischemic stroke who underwent revascularization therapy at our hospital. The primary outcome was the modified Rankin scale (mRS) score assessed three months post-treatment. Patients were categorized into two groups: those with a poor prognosis (mRS score > 2) and those with a good prognosis (mRS score≤2). The patients were divided into two groups based on the type of revascularization treatment received: thrombus extraction or intravenous thrombolysis. Logistic regression analysis was used to identify independent risk factors associated with the prognosis of patients treated with recanalization for acute ischemic stroke. RESULTS:Among the 94 patients, 59 had a good prognosis, and 35 had a poor prognosis. At admission, the patients in the good prognosis group exhibited lower NIHSS scores, shorter hospital stays, fewer previous cardiac events, lower LDL levels, fasting glucose, IL-6, and TNF-a compared to those in the poor prognosis group (all P < 0.05). Logistic regression analysis identified TNF-a (odd ratio (OD), 1.623; 95% confidence interval (CI), 1.282–1.933; P = 0.035) and IL-6 (OD, 1.055; 95% CI, 1.024–1.088, P = 0.023) as independent risk factors for poor prognosis in patients after revascularization. Additionally, pre-hospital NIHSS scores, IL-6, and TNF-a levels were significantly lower in the good prognosis group compared to the poor prognosis group, with these differences being statistically significant. CONCLUSION:IL-6 and TNF-α may serve as prognostic markers for outcomes following revascularization therapy in patients with acute ischemic stroke, including those receiving intravenous thrombolysis.
