Risk factors for ischaemic stroke in young Greenlanders.
BACKGROUND
Contrary to a widely held belief, ischaemic cerebral infarction is not a rare disease in Greenland, as shown recently by our institution. We report data on some of the known risk factors in patients below 60 years of age with ischaemic stroke.


METHODS
Retrospective data collection and review of charts from Greenlandic patients from all of Greenland admitted to the central hospital, Dronning Ingrids Hospital in Nuuk, in the years 2001 and 2002.


RESULTS
A total of 37 patients below 60 years of age were discharged with a diagnosis of cerebral infarction. All had a CT, which showed infarction in 32. Five were reported normal, and the diagnosis of infarction rested on the absence of haemorrhage combined with long-standing, major neurological defect. Median age of the group was 54 years. Fifteen (40%) were women, thirty (81%) were smokers. Nine (24%) had hypertension. Two had diabetes, one had atrial fibrillation, and one had dilated cardiomyopathy. Two had significant carotid atherosclerosis diagnosed by duplex ultrasound. Of the rest, fifteen had transoesophageal echocardiography done, thirteen of which showed atherosclerotic changes. The cholesterol levels showed relatively high HDL levels.


CONCLUSIONS
Ischaemic stroke is a common disease in young Greenlanders and seems to be associated with atherosclerosis with smoking as the only outstanding risk factor--though not more common than in the general population.
