American researchers have recently examined the question  of whether intensive glucose control improves functional outcome amongst people with hyperglycaemia after acute ischemic stroke. This was a randomised clinical trial included of 1151 adults (mean age 66 years) with hyperglycemia (glucose concentration of >110 mg/dL with diabetes or ≥150 mg/dL without diabetes). Subjects either received continuous intravenous insulin (target blood glucose concentration of 80-130 mg/dL [4.4-7.2 mmol/L]; intensive treatment group: n = 581) or SC insulin on a sliding scale (target blood glucose concentration of 80-179 mg/dL [4.4-9.9 mmol/L]; standard treatment group: n = 570) for up to 72 hours. The mean blood glucose level was 118 mg/dL (6.6 mmol/L) in the intensive treatment group and 179 mg/dL (9.9 mmol/L) in the standard treatment group. Favorable outcomes were seen in 119 of 581 patients (20.5%) in the intensive treatment group and in 123 of 570 patients (21.6%) in the standard treatment group. Treatment was stopped early for hypoglycemia or other adverse events in 65 of 581 patients (11.2%) in the intensive treatment group and in 18 of 570 patients (3.2%) in the standard treatment group. Severe hypoglycemia occurred only among patients in the intensive treatment group (15/581 [2.6%]). The conclusion was that intensive glucose control in this setting is probably not worth pursuing.
