Microalbuminuria and hyperthermia independently predict long-term mortality in acute ischemic stroke patients.
OBJECTIVE
To investigate the association between microalbuminuria (MA) and hyperthermia in acute ischemic stroke and to evaluate their significance as the predictors of long-term mortality after stroke.


METHODS
We assessed neurologic deficit, urinary albumin excretion and body temperature in 60 patients admitted within 24 h after the onset of their first ischemic stroke. Outcome was assessed by 90-day and 1-year mortality.


RESULTS
MA was found in 46.7% of patients. Hyperthermia was found in 18.3% patients on Day 1 and in 25% patients on Day 2. The correlation between albuminuria on Day 2 and the body temperature on Days 1 and 2 was found (r = 0.45, and r = 0.30, respectively; both P < 0.05). The mortality was significantly higher in the group of patients with both MA and hyperthermia on Day 2 (73% vs 10% after 90 days; P < 0.0001 and 73% vs 18% after 1 year, P < 0.005). In the logistic regression analysis, albuminuria (P = 0.017), hyperthermia on Day 1 (P = 0.028) and neurologic deficit on admission (P = 0.044) independently predicted 1-year mortality after ischemic stroke.


CONCLUSIONS
Daily urinary albumin excretion correlates with the body temperature in acute stroke patients, but the predictive power of both these variables is independent of that association.
