Hyperglycemia is present in 50 percent of patients with acute ischemic stroke. Patients with hyperglycemia have higher in hospital, 30 and 90 day mortality and morbidity. Sixty percent of these patients have some form of diabetic syndrome, known or unknown. Remaining 40% of patients are not diabetic. Contrary to logic patients with non diabetic hyperglycemia (NDH) have statistically higher morbidity and mortality compared to the diabetic hyperglycemia (DH) cohort. So far multiple treatment trials (THIS, GRASP, GIST-UK, SHINE ongoing) with differing treatment goals have shown no clear benefit, however no obvious distinction was made along the diabetic and non-diabetic hyperglycemic groups. If hyperglycemia in the acute phase was the only culprit in worsening the injury, then there should be no difference in the outcomes for DH and NDH. Existing data implies that the two categories are two distinct physiological entities that are thus not amenable to same treatment. Stating it simply NDH is not an insulin deficient state where as DH is. Alternative possibility is that body and Neurons are accustomed to high sugars in diabetics and thus can tolerate higher sugars better during ischemic stroke compared to non diabetics. The overarching hypothesis is that reducing blood sugars in NDH increases stroke volume and thus consequently worsens outcome.
