    Abstract:
    OBJECTIVES: To define a cardiovascular risk factor profile in very old patients with ischemic stroke. PATIENTS AND METHODS: Data from a prospective hospital-based stroke registry was collected. Demographic characteristics and cardiovascular risk factors in individuals aged 85 years or older with ischemic stroke (n=303) were compared with patients under 85 years (n=1537). RESULTS: The study population accounted for 16.5% of all cases of ischemic stroke. The mean (S.D.) age was 88.2 (2.8) years (70% women). Hypertension occurred in 44.9% of patients, atrial fibrillation in 42.6%, diabetes in 16.2%, and congestive heart failure in 15.5%. The most frequent stroke subtypes were cardioembolic (36%) and atherothrombotic (31.4%) infarction. Congestive heart failure (odds ratio [OR]=3.62), chronic renal disease (OR=2.54), female sex (OR=2.27), previous cerebrovascular disease (OR=1.71), and atrial fibrillation (OR=1.38) were significantly associated with ischemic stroke, whereas diabetes (OR=0.68), hypertension (OR=0.61), hyperlipidemia (OR=0.45), and heavy smoking (OR=0.21) occurred more frequently in patients under 85 years. CONCLUSION: Adequate treatment of potentially modifiable risk factors, including congestive heart failure, chronic renal disease, and atrial fibrillation may contribute to prevent ischemic stroke in very old people.
