Abstract

Our purpose was to evaluate the outcome of patients aged 70 years or older with a first-ever acute ischemic stroke and to identify the factors which determine poor outcome. Data from 115 patients, non-disabled prior to stroke, consecutively admitted to a medical department of a teaching hospital over a 30-month period, were prospectively collected at stroke onset and 6-month follow-up. Clinical and brain imaging findings and functional status were recorded. Predictors of unfavorable outcome at 6 months, defined as a modified Rankin Scale score >2, were analyzed by multiple logistic regression. The mean age of this cohort was 78.6 years (SD, 5.7) and 66.1% were women, 73.9% had hypertension, 25.2% diabetes, 36.0% atrial fibrillation (AF), 33.9% heart failure (HF), 15.8% previous transient ischemic attack (TIA), 47.8% a Charlson comorbidity index (CCI) score >1 and 52.2% a baseline National Institute of Health stroke scale (NIHSS) score >= 6. At 6 months, 54 patients (47%) had unfavorable outcome and the independent predictors of poor outcome were the initial systolic blood pressure and the NIHSS score on admission. In conclusion, near 50% of these old patients were dependent or dead 6 months after stroke onset and the main predictor of poor outcome was the neurological severity of stroke.
