[Platelet hyperfunction in prethrombotic vascular disease]

In 3 groups of patients with high thrombotic risk (diabetes mellitus, hyperbetalipoproteinemia, hypertension) the platelet aggregation and the level of circulating platelet aggregates were found statistically higher than in normal controls. In addition, platelet aggregation in diabetic patients was found statistically higher than in the other 2 groups of patients. Therefore these 2 parameters of platelet function are useful for the screening of patients with potential risk for thrombosis allowing a more selective and defined prophylaxis, both of thrombosis and atherosclerotic complications.
