Platelet adhesiveness in permanent residents of high altitude.

Platelet adhesiveness (PA) has been studied in 43 permanent residents of high altitude (highlanders) and in an equal number of age matched low landers for comparison. The importance of our findings in the light of our earlier observations in young low landers developing ischaemic cerebral stroke at high altitude and the development of ill effects of high altitude induction in fresh unacclimatised inductees is discussed.
