Abstract

Background. Among patients with acute cerebral circulation disorders, the frequency of hyperglycemia reaches 60%. To date, however, there is no consensus on the role of increasing glucose levels in the development of stroke, whether it has a physiological or pathological nature. Objective. Evaluation of the effect of hyperglycemia in the onset of ischemic stroke (IS) on the course and short-term clinical prognosis of the disease in patients with type 2 diabetes mellitus (DM2). Methods. 186 patients with IS and DM2 (54 men, 132 women) were examined, the average age was 67.8±7.72 years. Study design: case series. The degree of neurological deficit (NIHSS) and functional impairment (modified Rankin scale - mRs), and the fasting glucose level were assessed. The survey was carried out in the acute period of stroke at admission to the hospital and on the 21st day from the onset of the disease. Results. Hyperglycemia was detected in 76.3% of patients. Patients with glycemia >10.0 mmol/L were found to have a higher degree of neurological deficit than patients with normoglycemia (17.9%). Hyperglycemia >7.8 mmol/L was accompanied by a higher frequency of mRs 4-5 (by 25.6%) and a decrease in the incidence of apparent positive dynamics (by 27.7%). Conclusion. In DM2 patients, the development of IS is characterized by high levels of glycemia. Hyperglycemia is associated with the severity and clinical outcome of the disease.
