Summary: 
This article presents a review of Russian and foreign literature about the impact of arterial hypertension (AH) on the risk of cognitive impairment and dementia. Large studies have demonstrated the effect of blood pressure (BP) on the risk of vascular dementia and Alzheimer’s disease (AD) in elderly and oldest old people as well as a role of antihypertensive therapy. There is evidence of a negative effect of hypertension in middle age on cognitive functions in late-life. Observational studies as a whole have shown the positive effect of antihypertensive therapy on the prevention of cognitive function and dementia. However, there are a number of limitations that dictate the need for further research on this issue. The importance of the interdisciplinary approach to treatment of cognitive impairment by cardiologists and/or therapists, together with neurologists, as well as complex treatment regimens, including correction of risk factors and neuroprotective therapy, is highlighted.

Keywords: arterial hypertension, cognitive impairment, dementia, Alzheimer disease, antihypertensive therapy.

Summary:
Aim. To evaluate efficacy and safety of original ethylmethylhydroxypyridine succinate (Mexidol) in cardiological patients ≥75 year old. Material and methods. In the observational study, according to ethical standards of Khelsinki Declaration, with informed consent, 24 patients participated, age 75-88 y. o. Inclusion criteria: age ≥75 y. o.; already diagnosed coronary heart disease (CHD) and/or chronic heart failure (CHF); Mexidol usage. Exclusion criteria: absent informed consent, severe comorbidities. Mean age of the patients at inclusion 80,33±4,06 y. o.; 16 (66,7%) females and 8 (33,3%) males. Patients consequently visited office of cardiologist with the diagnoses: chronic CHD (I25.0-I25.9), CHF with preserved systolic function (I50.0-I50.9). All patients were consulted by neurologist, had an established diagnosis of cerebrovascular disease (I65-67). To reduce the symptoms of frailty, among the neurologist recommendations, with accordance to routine clinical practice, the original Mexidol was included. Mexidol was prescribed by a scheme of manufacturer: intravenous infusions 500 mg x 5 days, then per os 125 mg t. i.d.; overall treatment — 8 weeks. Results. Statistically significant results were noted in 6 months from the study start. There was significant increase of 6 minute walking distance in men from 304,00±87,09 to 388,63±92,28 m (р=0,01), in women from 346,06±56,81 to 427,69±76,87 m (р=0,003); also there were less signs of frailty. No one patient showed significant worsening of the condition; during the overall follow-up, patients did not call emergency or primary care physicians and did not hospitalize. Conclusion. In comorbidity patients aged ≥75 y. o. at Mexidol treatment, there was increase of 6-minute walking test distance, decrease of asthenia signs, that witness for the medication efficacy. All patients showed good tolerability of the drug that witness for safety. Obviously, there are broad trials needed to sum up a gerontological algorithm of CHD and CHF patient management in outpatient setting.

Summary:
Aim. To study an effectiveness of mexidol (ethylmethylhydroxypyridine succinate) for kidney injury in patients with ST-elevation myocardial infarction (STEMI). Material and methods. The study involved 55 STEMI patients. Acute renal injury (ARI) was determined according to basal creatinine, serum creatinine, glomerular filtration rate, cystatin C and NGAL. In STEMI patients standard therapy was supplemented by antioxidant (cytoprotector) mexidol from the 1st to the 10th day 750 mg/day intravenously. ARI values were assessed after treatment. Results. There were 36 ARI patients among 55 patients with STEMI. Therapy with mexidol significantly decreased ARI severity (urine creatinine, cystatin C and NGAL values) after 48 hours. Conclusion. Mexidol may be used in addition to standard therapy in STEMI patients to reduce ARI severity.

Keywords: cytoprotectors, myocardial infarction, acute renal injury.

Summary:
It was analyzed the mexidol influence on phospholipid metabolism in acute coronary syndrome (ACS). The study included 70 patients. Intravenous mexidol infusions were included in the complex therapy in 30 cases. Conventional clinical and laboratory data, as well as the absorption of lipid phospholipid complexes in the infrared spectrum of blood serum were evaluated. The study established a mechanism of phospholipids autoregulation as a wave-like fluctuations of their concentration in the blood serum with early increasing (compared with healthy) in the first hours and days of development of ACS. It was observed the maximum rise by the 4th day and a moderate decline by the 10 day of observation reflecting the degree of adaptation systems stress. Regardless on the clinical form of ACS mexidol application eliminates oscillatory nature of the phospholipids dynamics. It is stabilizing their rise at a level sufficient to ensure the power and plastic needs of the organism and myocardium that improves the results of combined treatment.

Keywords: acute coronary syndrome, homeostasis, phospholipids, mexidol, infrared spectrometry.

Summary:
Abstract: the paper describes the study of the state of LP0‐AOD system in the patients with coronary artery disease and type 2 diabetes and the effect of antioxidant therapy on metabolic factors. Timely correction of disorders contributed to the positive dynamics of metabolic processes, and on the background of this, reduced frequency of cardiovascular complications.

Summary: 
Aim — to estimate effect of Mexidol on blood lipids in patients with high cardiovascular risk and diabetes mellitus type 2 (DM2). Material and methods. Two groups of patients with DM2 as the main risk factor of vascular complications were prospectively followed-up within 3 months. Achievement of target blood lipid was compared in standard therapy with statins (group 1) and addition of Mexidol to basic therapy (group 2). Enzymatic colorimetric method was used to determine blood lipids level (Boehringer Mannheim, Germany). Results. There was a positive effect of Mexidol at the initial stage of statins therapy that was expressed by normalized lipids level in DM2 patients with high and very high cardiovascular risk.

Keywords: cardiovascular complications, diabetes mellitus type 2, dyslipidemia, prevention, Mexidol.
