Impact of serum apolipoproteins on the prognosis of acute ischemic stroke after thrombolysis

Objective: The purpose of this study is to the relationship between peripheral apolipoproteins and the prognosis of patients with acute ischemic stroke (AIS) after thrombolysis. Methods: A total of 231 AIS patients with thrombolysis was enrolled. Serum apolipoproteins were measured on admission after thrombolysis. All patients enrolled were followed up for 90 days. Their functional outcomes were assessed by the modified Rankin Scale (mRS). Good functional outcome was considered as mRS < 3. Logistic regression was applied to assess the association between serum apolipoproteins and the mRS at 90 days. Results: In multivariate analysis,1) ApoB (OR=0.099, 95%CI=0.017 similar to 0.575, p=0.010) and ApoB/ApoA-1(OR=0.113, 95%CI=0.015 similar to 0.868, p=0.036) were independent risk factors of good functional outcome at 90 days. 2). there were significant differences in the mRS score distribution at 90 days in groups according to the ROC cutoff values of ApoB (0.85g/L) and ApoB/ApoA-1 ratio (0.61) (all p<0.05). Conclusion: Our findings demonstrated ApoB and ApoB/apoA-1 ratio were independent risk factors for good functional outcome at 90 days, and the ApoB level below 0.85g/L and ApoB/ApoA-1 ratio below 0.61 could be associated with a better functional outcome in this study population.
