Why the study?
Are plasma beta-thromboglobulin levels elevated in different subtypes of acute cerebral infarction and do they correlate with outcomes?
Are plasma beta-thromboglobulin levels elevated in different subtypes of acute cerebral infarction and do they correlate with outcomes?
Plasma beta-thromboglobulin is elevated in acute atherosclerotic and cardioembolic strokes but not lacunar strokes, and predicts mortality in atherothrombotic stroke, suggesting a primary role for platelet aggregation in atherothrombosis.
BTG elevation may aid acute non-lacunar stroke differentiation; leaves open prognostic or therapeutic utility in observational data.
Plasma beta-thromboglobulin (BTG) was significantly elevated in the acute phase of 116 atherosclerotic thrombotic (p less than 0.0001) and 36 cardioembolic (p less than 0.005) infarcts but normal for 96 lacunes compared with controls. This elevation persisted into the 6th week after the acute event. Among atherosclerotic thrombotic infarcts, the acute beta-thromboglobulin level showed a tendency to correlate with infarct size on CT and predicted mortality at 6 weeks. These results suggest that platelet aggregation plays a primary role in the pathogenesis of atherothrombosis.
