Genetic predisposition alongside with environmental factors play a major role in the pathogenesis of coronary heart disease, causing the deregulation of various biochemical processes leading to the disease onset. Antioxidant system deregulation, marked mainly by lipid peroxidation products and a number of enzymes, is known to be one of the risk factors for coronary heart disease. A genetic defect might lead to a change in enzyme activity and inhibition of antioxidant protection. However, the pathogenic factors and antioxidant system deregulation mechanisms in different clinical courses of coronary heart disease are not studied enough as phenotypic expression of genetic polymorphism is largely dependent on the gene pool and the living conditions of a particular population, explaining the controversial data on the association of polymorphisms candidate genes with the risk of coronary heart disease. Currently, the role of genes encoding antioxidant system enzymes in predisposition to coronary heart disease development is not sufficiently studied, and research results are contradictory. The review summarizes the current data on the antioxidant system genes (superoxide dismutase enzymes, glutathione peroxidase and catalase) genetic polymorphisms association with the risk of coronary heart disease (as an acute myocardial infarction, angina рectoris).
Arterial hypertension (AH) is the major modifiable risk factor for cognitive impairment (CI), including dementia, CI in cerebrovascular and neurodegenerative diseases, including Alzheimers disease. By 2050, the number of people with dementia will approximately 3 times increase due to the aging population and limited opportunities for drug prevention and treatment of severe CI. In connection with the above, it seems necessary to create an expert consensus, which would summarize the evidence-based medicine data available to date on the effect of antihypertensive therapy (AHT) on cognitive function (CF). In the expert consensus, the data of prospective randomized clinical trials, observational and population studies, meta-analyzes on the effect of AHT on the risk of dementia and CI progression, including certain CF, were summarized and analyzed. The consensus considers the effect of antihypertensive drugs (AHD) on various cognitive domains. Literature data give evidence that AHT reduces the risk for dementia, including vascular dementia, reduces the risk of for dementia in Alzheimers disease, as well as reduces the risk and can prevent the progression of non-dementia CI. The effect of AHT on various CF has been little studied. Most meta-analyzes did not reveal the benefits of any class of AHD; however, one study demonstrated the advantage of angiotensin receptor blockers, while another study diuretics. The consensus emphasizes that, given the high incidence of AH in the general population, AHT may be one of the most effective ways to prevent CI or delay CI progression. The effect of different classes of AHD on CF requires further study. It is necessary to conduct a larger number of well-designed randomized clinical trials that would assess the state of executive functions in patients with AH.
Aim. To study the prevalence and structure of periodontal disease in in-patients with coronary heart disease preparing for coronary artery bypass surgery.Methods. The study included 144 male in-patients with coronary heart disease who were prepared for coronary artery bypass surgery in the department of cardiac surgery. The diagnosis of periodontal disease was set according to the World Health Organization recommendations based on the comprehensive dental examination. Exclusion criteria were: diabetes mellitus, survived blood transfusions and all teeth missing. A prognostic model based on binary logistic regression method was created for estimation of risk factors on periodontal disease risk.Results.The prevalence of chronic generalized periodontitis in patients with coronary heart disease preparing for coronary artery bypass surgery reaches 73.6%. Mild (51.9%) and moderately severe (48.1%) chronic generalized periodontitis were the most common. Among the risk factors for periodontal disease patients, we have identified older age, smoking, hypertension and survived acute ischemic episodes. For the created model, χ2 value was assessed as 42.7, meaning statistical significance of pConclusion. In in-patients with coronary heart disease, prophylaxis for periodontal disease should be performed to decrease the risk for exacerbations. Using the created prognostic tool in clinical practice may be used for outlining patients with higher risk for periodontal disease.
Aim. To assess the efficacy and safety of Vamloset (amlodipine/valsartan 5/80, 5/160, 10/160 mg) and Co-Vamloset (amlodipine/valsartan/hydrochlorothiazide 10/160/12.5, 10/160/25 mg) in achieving the target levels of blood pressure (BP) in patients with stage 23 arterial hypertension (AH). The article discusses indicators affecting adherence to antihypertensive therapy (AHT). Material and methods. The VICTORY II Russian study in 8 clinical centers of the Russian Federation included 103 patients over 18 years of age with stage 23 essential AH (who havent been previously treated and have office systolic BP160 mm Hg and/or diastolic BP100 mm Hg or who havent reached the target office blood pressure with mono- or double AHT). The Full Analysis Set (FAS) for efficacy analysis included 99 patients, a FAS population with the restoration of data missed using Last Observation Carried Forward. The SF-36 questionnaire for assessing the quality of life, the effect on erectile function in men, the convenience of current therapy from the point of view of patients were analyzed after 16 weeks of treatment. The Per Protocol (PP) population included 80 patients completing the study without major protocol deviations to assess the primary parameters of efficacy. All patients with stage 2 hypertension were prescribed Vamloset (amlodipine/valsartan 5/80 mg), with stage 3 hypertension amlodipine/valsartan 5/160 mg. Dose titration of Vamloset and Co-Vamloset (LLC Krka-RUS) was carried out every 4 weeks according to the AHT schemes. Results. The studys active phase included 100 patients aged 59.510.9 years (women 59%) with AH duration of 83.48.4 months; 83% of patients received AHT prior inclusion in the study. In the PP population, 16 week- AHT with Vamloset or Co-Vamloset allowed reaching the target BP in 90.0% of patients (95% confidence interval [CI] 81.295.6). Overall clinical efficacy was achieved in 98.8% of patients (95% CI 93.2100.0). All treatment regimens were characterized by high patient compliance. In the total group, 50% of patients rated their AHT as more convenient than they had previously used; of them, in the stage 2 AH group 47.8%, in the stage 3 AH group 53.3%. Metabolic neutrality with regard to at least one indicator was observed in 100% of patients, with regard to 6 indicators in 43.9% [33.9; 54.9]. For all 98 patients included in the analysis, changes in all SF-36 scales, except for physical functioning (p=0.339), were statistically significant (p0.05). The effect of AHT on erectile function was rated as positive in 51.3% of men. Good tolerance data are consistent with the established drug safety profile. Conclusion. In the VICTORY II study, high antihypertensive efficacy and an improvement in a set of indicators of optimal adherence to AHT by Vamloset and Co-Vamloset within 16 weeks were proved in patients with stage 23 AH. Patients high rating for quality improvement in the quality of life, safety of therapy and ease of use ensured optimal compliance of Vamloset and Co-Vamloset therapy throughout the study.
