Aim. To compare the effect of beta-blocker therapy (bisoprolol and nebivolol) on the dynamics of fibrotic and vascular endothelial dysfunction markers in elderly hypertensive patients after ischemic stroke (IS).Material and methods. This prospective cohort study included 75 hypertensive patients who were admitted to the hospital due to IS. The mean age of patients was 67±6 years. The average National Institutes of Health Stroke Scale (NIHSS) score was 7±3. The followup period was 6 months. The control group consisted of 20 elderly people with hypertension without prior myocardial infarction. The patients were divided into groups based on received therapy: group 1 (n=38) — bisoprolol; group 2 (n=37) — nebivolol. The level of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) was determined by enzyme-linked immunosorbent assay (ELISAKit, USA). Vascular ultrasound was carried out using a LOGIQP9 (GE) system according to the Celermajer method.Results. After 6-month nebivolol, we revealed a decrease in the level of MMP-9 by 30,2% (p<0,01), TIMP-1 by 15,6% (p<0,05). After 6-month bisoprolol therapy, the level of MMP-9 decreased by 14,5% (p<0,05), while TIMP-1 did not change. Intergroup comparison found that when using nebivolol, there was a higher decrease in the level of MMP-9 by 15,7% (p<0,05), TIMP-1 by 9,7% (p<0,05), MMP-9/TIMP-1 by 7,8% (p<0,05) than with bisoprolol therapy. After 6-month bisoprolol therapy, there was a decrease in the proportion of patients with severe endothelial dysfunction (ED) by 7,9% (p<0,05). Two patients from the nebivolol group moved into mild ED category. The number of patients with moderate ED increased by 19% (p<0,01), while prevalence of severe ED decreased by 24,4% (p<0,01).Conclusion. The results obtained indicate that the beta-blocker nebivolol at an average dose of 8,55+1,75 mg/day significantly reduces the vascular fibrosis, normalizes the ratio of collagen synthesis and degradation markers, improves the vasodilation brachial artery properties in comparison with bisoprolol in elderly hypertensive patients after IS.
