bet .. as opposed to a .. longshot bet .. chances of winning /
stroking out .. are pretty good / bad.

High Altitude Medicine & Biology Stroke at High Altitude:
Indian Experience
Stroke is a common medical emergency. There is limited
knowledge about stroke at high altitude. We present the
clinical profile of 30 cases of stroke at high altitude seen
at our center between November 1998 to July 2000. A detailed
neurological and systemic examination was carried out. Cases
were investigated with blood counts, lipid profile, cardiac
evaluation, and CT scan/MRI. Coagulation parameters were
studied in some cases. Strokes formed 13.7/1000 of hospital
admissions from high altitude area, compared to 1.05/1000 in
nonhigh altitude area. All our cases from high altitude area
were males (serving soldiers of armed forces). Their mean high
altitude stay was 10.2 months, and they were all located at
heights greater than 4270 m. Age ranged from 22 to 48 years
(mean 33.4 yr). Except for smoking (in four cases), they had
no preexisting risk factors. Twenty-two cases were of ischemic
stroke, 2 of intracerebral hemorrhage, 4 of TIA/RIND
(transient ischemic attack/reversible ischemic neurological
deficit), and 2 had cerebral venous thrombosis. Out of 30
cases, 28 were of "stroke in young" (<45 yr) and were compared
with cases in the same age group from nonhigh altitude areas.
Polycythemia with Hb ranging from 16.2 to 22 g=B7dL-1 was seen
in 21 of these 28 cases (75%). Protein C and S deficiency was
found in 1 case in each group. CT scan showed massive infarcts
involving at least 50% of one cerebral hemisphere in 12 cases.
Multiple infarcts were seen in one case. Conclusion: Long-
term stay at high altitude is associated with higher risk of
stroke. Although all types of stroke were seen, ischemic
stroke was the commonest. Massive infarcts were common.
Polycythemia was an important risk factor.
