One hundred and seventy five @entity9398 ( @entity9398 ) @entity1 were evaluated for risk factors for @entity64 as well as for the types of @entity75 that were present. The incidence of associated risk factors for @entity64 were as follows: @entity101 (66%), @entity299 (47%), cigarette smoking (37%), @entity6 (20%), moderate @entity167 consumption (19%) and hyperlipidaemia (21%). The most frequently occurring @entity75 were multiple @entity1188 of the brain (43%). These were combined with other types of @entity64 in an additional 21%. @entity731 of the carotid and vertebrobasilar arteries occurred alone in 18% and was associated with other types of @entity64 in another 25%. @entity385 were present alone in 8% and were combined with other types of @entity64 in 15%. @entity9398 was more frequent in @entity1 (62%) than @entity1 (p less than 0.002). Mean bihemispheric gray matter cerebral blood flow (CBF) values showed a fluctuating course and when results were pooled and compared between different types of @entity9398 , @entity432 and/or multiple @entity1188 resulted in lowest CBF values. The location of @entity385 was more importantly related to @entity73 than was the total volume of infarcted brain. Mortality rates among 125 @entity9398 @entity1 followed for 31 months has been 5%. Correct clinical classification of the types of @entity75 was confirmed in three necropsied cases.
