Abstract

OBJECTIVES For Greece, data on incidence of stroke, type of stroke, and prognosis of stroke is limited. Recently, results on incidence of stroke were published. Here 1 year mortality, functional outcome after a first ever stroke, and determinants of the prognosis are described.

METHODS A population based registry was established in the Arcadia area, located in eastern central Peloponessos in southern Greece. Between 1 November 1993 and 31 October 1995, 555 patients with a first ever stroke were identified using information from death certificates, hospital records, public health centres and general practitioners. Extensive information on cardiovascular 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 probability of survival 1 year after stroke was higher for cerebral infarction than for intracerebral haemorrhage; 67.8% (95% confidence interval (95% CI) 64–72) and 46.4% (35–57), respectively. Of the survivors, 68.9% had either no symptoms or symptoms that would not interfere with their capacity to look after themselves (Rankin score 0 to 2). Increasing age and low Glasgow coma scale 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.
