XXXX in Spain: epidemiologic incidence and patterns; a health sentinel network study.

@entity1 @entity64 @entity66 @entity697
INTRODUCTION: @entity66 is among the 4 main causes of mortality in Spain. The objective of this study was to estimate the incidence of @entity64 and to describe the principal risk factors and other clinical and epidemiologic patterns found in @entity1 . METHODS: Doctors from the Spanish sentinel health network recorded the episodes of @entity697 in 2005 in a population of 201,205 inhabitants older than 14 years. The information of the @entity1 (age and sex) and the episode (e.g., duration, symptoms, origin, medical attention, risk factors) was collected on a standard form. RESULTS: The estimated incidence rate of @entity64 was 141 cases per 100,000 inhabitants (confidence interval [CI] 95%: 125-158), 134 (95% CI: 112-157) in @entity1 and 148 (95% CI: 124-172) in @entity1 . The incidence increases significantly from the age of 65 years and @entity1 younger than this have higher rates than @entity1 . In all, 12% of @entity1 with @entity64 die within the first 24 hours. CONCLUSIONS: Incidence of @entity66 in Spain is below that recorded in other countries. There is no difference according to sex, but incidence among young and middle-aged @entity1 is greater than that among @entity1 . Significant variations from some population groups to others are observed, maybe because of the difference in the prevalence of risk factors.
