Objective:
To evaluate the hemostasis of plasma aminothiols in different subtypes of ischemic stroke (IS).
Material And Methods:
The study included 177 patients, aged 62 (55-68) years, admitted in the first 8-24 hours since IS onset. The pathogenetic subtype of IS was clarified according to the results of clinical and instrumental examination by the Trial of ORG 10172 in Acute Stroke Treatment criteria. Determination of the total plasma aminothiols levels, their reduced forms and redox status was performed using the ultra-efficient Acquity H-Class UPLC liquid chromatograph (Waters, CSHA).
Results:
Large-artery atherosclerosis was diagnosed in 24.3% patients, cardioembolic stroke in 20.3%, lacunar stroke in 55.4%. Significant differences in total levels of cysteine (Cys), glutathione (Gsh) and homocysteine (Hcy) were identified in patients with different IS subtypes. Patients with large-artery atherosclerosis and lacunar stroke showed the highest level of Hcy, patients with cardioembolic stroke had the lowest levels of Cys and Gsh.
Conclusion:
Total levels of plasma aminothiols are associated with different subtypes of IS.
