Abstract
Objectives-For Greece, data on incidence of stroke, type of stroke, and pro gnosis of stroke is limited. Recently, results on incidence of stroke were published. Here 1 year mortality, functional outcome after a first ever str oke, and determinants of the prognosis are described. Methods-A population based registry was established in the Arcadia area, lo cated in eastern central Peloponessos in southern Greece. Between 1 Novembe r 1993 and 31 October 1995, 555 patients with a first ever stroke were iden tified using information from death certificates, hospital records, public health centres and general practitioners. Extensive information on cardiova scular risk factors and stroke characteristics was obtained. After 1 year a modified Rankin score was determined in all surviving patients. Results-After 1 year of follow up, 204 (36.8%) patients died. The probabili ty of survival 1 year after stroke was higher for cerebral infarction than for intracerebral haemorrhage; 67.8% (95% confidence interval (95% CI) 64-7 2) and 46.4% (35-57), respectively. Of the survivors, 68.9% had either no s ymptoms or symptoms that would not interfere with their capacity to look af ter themselves (Rankin score 9 to 2). Increasing age and low Glasgow coma s cale score were the most powerful predictors of death within 1 year (p<0.01 ), whereas increasing age, atrial fibrillation, and low Glasgow coma scale score were the most important predictors of functional outcome 1 year after a stroke (p<0.01). Conclusions-One year mortality from stroke in Greece is similar to that of other industrialised countries. The most important factors that affect the prognosis of a patient with a first ever stroke are increasing age, stroke severity, and atrial fibrillation.
