[Postregistration study of comparative assessment efficacy of the use of fixed combination of nebivolol and amlodipine for the treatment of patients with moderate and high degree of arterial hypertension].

AIM: of the study was to assess efficacy of the use of fixed combination of nebivolol and amlodipine in patients with moderate and high degree of arterial hypertension (AH). MATERIAL AND METHODS: Patients with diagnosis of primary AH (n=124) were divided into 2 groups by random sample method. Patients of group 1 (n=62) received of fixed combination of nebivolol and amlodipine, while those of group 2 (n=62) received free combination of nebivolol and amlodipine. Study drugs were administered both as initial therapy and replacement of preceding treatment. Duration of observation was 3 months with visits after first 2 weeks and in 1, 2, and 3 months after enrollment. RESULTS: Starting from 2nd week visit of fixed combination of nebivolol and amlodipine treated patients had significantly lower levels of systolic and diastolic AP. Already after 2 weeks of combined two-component therapy 60% of group 1 and 52% of group 2 patients achieved target AP. Target AP was achieved by the end of month 1 by 86 and 71%, of month 2 - by 93 and 78% of patients in groups 1 and 2, respectively. In 3 months almost all patients had target AP, but in 1.6% of group 1 and 2.3% of group 2 patients this level was achieved after addition of a thiazide diuretic. Patients receiving of fixed combination of nebivolol and amlodipine achieved noromosyslolia more quickly compared with patients who received free combination of nebivolol and amlodipine. CONCLUSION: Combined therapy with fixed combination of nebivolol and amlodipine appears to be one of effective approaches to treatment of patients with moderate and high degree AH.

[The role of matrix metalloproteinases in assessment of prognosis in patients with ST-elevation myocardial infarction during hospital stay].

Aim of the study was to investigate role of matrix metalloproteinases (MMP) in assessment of prognosis of repetitive cardiovascular events during hospital stay of patients with ST-elevation (STE) myocardial infarction (MI). We consecutively included into this study 175 patients with diagnosis of STEMI. Content of MMP-1, MMP-3 and MMP-9 in blood serum was measured at admission and on day 12 after onset of disease. Levels of all MMPs on day 12 were 1.1-1.6 times higher than on day 1 of MI (<0.05). Comparison of groups of patients with favorable and unfavorable outcome showed that patients with unfavorable outcome had higher median concentrations of MMP-3 and MMP-9 on day 1; this tendency was maintained on day 12. However these differences were significant only for MMP-9. Compared with patients with favorable outcome levels of this marker in patients with unfavorable outcome were higher by 19.4% (=0.04) on day 1 and by 48.8% (=0.03) on day 12. At logistic regression analysis for MMP-9 and unfavorable outcomes during hospital stay area under ROC-curve did not exceed 0.5. But when only inhospital deaths were considered 2 for MMP-9 (day 1) was 14.3 (<0.0001) while area under ROC-curve was 0.72 (0.64; 0.78; =0.02). Thus in patients with STEMI high concentrations of MMP-9 on day 1 of STEMI can come forward as independent marker of unfavorable outcome during hospital stay.
