[Chronic cerebral ischemia in therapeutic hospital patients].

Objective: To study the features of clinical and functional manifestations of the syndrome of chronic cerebral ischemia (CCI) in therapeutic patients.

Material and methods: Patients (n=577) in therapeutic departments were selected by random sampling. Of these, 277 patients had verified CCI.

Results: Patients with CCI, compared with the control group, were older (61.7±9.6 years and 43.3±12.2 years, p<0.05), had a significant increase in body mass index (28.5±5.1 and 26.9±5.7 kg/m², p<0.05), systolic level (140±20 and 127±17 mmHg, p<0.05) and diastolic blood pressure (87±10 and 82±11 mm Hg, p<0.05), platelet count in peripheral blood (278.0±70.7·10⁹/l and 259.1±80.8·10⁹/l, p<0.05), venous blood glucose (7.11±3.8 and 5.31±1.7 mmol/l, p<0.05), triglycerides (1.37 (1.01; 1.97) mmol/l and 1.34 (0.96; 1.96) mmol/l, p<0.05), uric acid (0.425±0.12 and 0.374±0.14 mmol/l, p<0.05), creatinine (82.7 (68.0; 114.0) µmol/l and 72.3 (61.8; 93.0) µmol/l, p<0.05) and cystatin C (1.24 (1.08;1.62) mg/l and 1.01 (0.87; 1.32) mg/l, p<0.05). Statistically significant decrease in the concentration of high-density lipoprotein cholesterol (1.0±0.28 mmol/l and 1.2±0.32 mmol/l, p<0.05), serum magnesium (0.90±0.15 and 0.94±0.13 mmol/l, p<0.05) and estimated GFR (57.9±24 and 72.6±26.8 ml/min, p<0.05) were characteristic of patients with CCI. Elevated levels of C-reactive protein and anemia were significantly more common in these patients. A close correlation was found between the concentrations of uric acid (r=0.786; p<0.001) and cystatin C (r=0.587; p<0.005) in blood serum and the thickness of the intima-media complex of the carotid arteries.

Conclusion: In patients of a therapeutic hospital, CCI is associated with older age, weight gain, arterial hypertension, dyslipidemia, anemia, inflammation, hypomagnesemia, hyperuricemia, thickening of the intima-media complex of the carotid arteries, and a decrease in the functional state of the kidneys.
