Abstract
To study the impact of blood glucose concentrations on early stroke mortality in diabetic and non-diabetic stroke patients, and to identify the optimal blood glucose concentration for each patient category. A representative sample of 81 diabetic and 366 non-diabetic stroke patients was studied. Logistic regression analyses were performed in order to estimate the impact of blood glucose concentrations on admission and during hospital stay and other clinical parameters on 30-day case-fatality. Receiver operating characteristic curves were used to predict case-fatality by blood glucose. Blood glucose, body temperature and level of consciousness were independently related to early stroke mortality in diabetic and non-diabetic patients. The mean blood glucose concentration had a greater impact on 30-day case-fatality than the admission blood glucose, particularly in diabetic patients. A mean blood glucose concentration above 10.3 mmol/l predicted 30-day case-fatality in diabetic patients. The corresponding value was 6.3 mmol/l in non-diabetic patients. Improved blood glucose control has a potential to reduce early stroke mortality. The optimal glucose concentration seems to be higher in diabetic than in non-diabetic patients.
