Of all patients,95%had at least one complication.The most common serious medical complication was pneumonia(5%),and the most common serious neurological complication was new cerebral infarction or extension of the admission infarction(5%).The 3-month mortality was 14%;51%of these deaths were attributed primarily to medical complications.Outcome was significantly worse in patients with serious medical complications,after adjustment for baseline imbalances,as measured by the Barthel Index(odds ratio[OR],6.1;95%confidence interval[CI],2.5 to 15.1)and by the Glasgow Outcome Scale(OR,11.6;95%CI,4.3 to 30.9).After death was discounted, serious medical complications were associated with severe disability at 3 months as determined by the Glasgow Outcome Scale(OR,4.4;95%CI,1.3 to 14. 8).Medical complications that follow ischemic stroke not only influence mortality but may influence functional outcome. |
