[Epidemiology of acute cerebrovascular disease in Lleida from 1996 to 1997. Predictive factors of mortality at short and medium term].
BACKGROUND
Given the great clinical relevance of the cerebrovascular disease, the incidence, nosology, vascular risk factors and factors predicting short and medium-term survival after stroke were evaluated in Lleida (Spain).


METHODS
Five hundred forty-five consecutive patients with an acute stroke admitted to the Hospital Universitario Arnau de Vilanova during the period 1996-1997 were evaluated. A descriptive epidemiological study and a multivariate logistic regression analysis of predictive factors of mortality at 1-month and 1-year after the stroke were made. The latter provided a clinical scoring system for predicting survival.


RESULTS
The incidence rate of stroke was 138.3/100,000 inhabitants. Significant risk factors were hypertension and peripheral vasculopathy. There were 80.1% of ischemic and 19.9% of hemorrhagic strokes (p < 0.001). A Glasgow scale < or = 7, hemianopsia and hemorraghic stroke were significant predictors of 1-month mortality, whereas age > or = 70 years, diabetes, atrial fibrillation and limb weakness decreased survival at 1 year.


CONCLUSIONS
The incidence rate of stroke in Lleida is low respect to other studies in Spain. Simple clinical measures may help to establish a prognosis at short and medium-term.
