[Hematocrit and hemoglobin in the pathogenesis of transient cerebral ischemic attacks]

The hematocrit and the concentration of hemoglobin have been studied in 77 patients (42 men and 35 women) affected by transient cerebral ischaemic attacks involving carotid or vertebral-basilar arterial system. The results have been analysed statistically and compared to those of a control group, formed by 123 neurologic patients (68 men and 55 women) chosen at random, belonging to the same age range, and with no acute or chronic cerebrovascular disease. The hematocrit and the concentration of hemoglobin, although within normal limits, were significantly higher than in the control group only in the male patients with transient cerebral ischaemic attacks.
