Parameters reflecting cardiovascular health and inflammation were studied in a pilot clinical trial conducted on 40 patients with prehypertension. The patients were treated with a new proprietary formulation of a whey protein (WP) isolate embedded into lycopene micelles (WPL) during a 1-month period. Control groups received lycopene or WP as a singular formulation or placebo pills for the same period of time. Combined WPL formulation of whey protein and lycopene has caused multiple favorable changes in the cardiovascular function (including a tendency to the reduced systemic blood pressure), the plasma lipid profile, and the inflammatory status of patients with prehypertension, whereas singular formulations of the compounds and placebo did not have such an effect. The reduction of plasma triglycerides and cholesterol fractions and almost two-fold decline in C-reactive protein (CRP) and inflammatory oxidative damage (IOD) levels as well as an increase in nitric oxide (NO), tissue oxygenation (StO2), and flow-mediated dilation values constitute the most significant benefit/outcome of the treatment with the combined formulation of whey protein and lycopene. The treatment did not affect the values of ankle-brachial index (ABI), body weight, and body mass index (BMI).

Twenty-nine healthy volunteers aged 47–69 years old were randomly assigned to a 28-day oral intake of different dark chocolate (DC) formulations. The main group received daily 30 g of proprietary lycopene-containing (L-tug) lycosome formulation of DC with enhanced bioavailability of cocoa flavanols. Two control groups daily consumed either 30 g of regular DC alone or along with 7 mg of lycopene, which corresponds to the amount of lycopene ingested with L-tug formulation. It was found that L-tug was more efficient in reducing diastolic blood pressure (mean value of −6.22 mmHg, 95% CI: 5.00, 8.00) when compared with the regular DC group (−3.00 mmHg, P < 0.05) or the group which ingested the DC and lycopene as two separate formulations (mean reduction of −4 mmHg, 95% CI: 2.47, 6.00, P = 0.0262). Only marginal superiority for L-tug formulation in the reduction in systolic blood pressure was seen. However, the L-tug formulation was the only formulation of DC which affected serum lipids. There was a reduction in total cholesterol (from median 228.00 mg/dL [95% CI: 206.2, 242.5] to 187.00 mg/dL [95% CI: 166.2, 202.2, P < 0.05]) with corresponding decline of low-density lipoprotein (LDL) cholesterol (from a median of 166.00 mg/dL [95% CI: 130.8, 177.0] to 151.00 mg/dL [95% CI: 122.8, 167.4; P < 0.05]) at the end of the intervention period. Similar decline was seen in serum triglycerides (P < 0.05). Serum high-density lipoprotein (HDL) cholesterol, glucose levels, and C-reactive protein (CRP) values remained statistically unchanged in all study groups throughout the intervention period. A superior biological activity of the L-tug lycosome formulation of DC extending beyond its antihypertensive effect to lipid-lowering ability opens up new possibilities for the use of DC for health purposes helping to reduce daily caloric intake without compromising on the health benefits of DC consumption.

Oxidative stress and antioxidant deficiency play a pivotal role in initiation, development, and outcomes of cardiovascular disease. Pharmacokinetic parameters as well as the impact of highly bioavailable lycopene on cardiovascular variables, markers of inflammation and oxidation were investigated during a 30‐day clinical trial in patients with coronary vascular disease. The patients were randomized into two major groups and were supplemented with a single 7 mg daily dose of lycopene ingested either in the form of lactolycopene (68 patients) or in the form of lycosome‐formulated GA lycopene (74 patients). The endpoints included cardiovascular function parameters, serum lipids, and four markers of oxidative stress and inflammation. Ingestion of lycosome‐formulated lycopene increased serum lycopene levels by 2.9‐ and 4.3‐fold, respectively, after 2 and 4 weeks of the trial, whereas supplementation with lactolycopene upregulated serum lycopene by half‐fold only after 4 weeks of ingestion. Lycosome formulation of lycopene resulted by the end of the trial in a threefold reduction in Chlamydia pneumoniae IgG and reduction to the same degree of the inflammatory oxidative damage marker. The decrease in oxidized LDL caused by lycosome‐formulated lycopene was fivefold. Moreover, supplementation with lycosome‐formulated lycopene was accompanied by a significant increase in tissue oxygenation and flow‐mediated dilation by the end of the observational period. In contrast, lactolycopene did not cause any significant changes in the parameters studied. Therefore, enhanced bioavailability of lycopene promotes its antioxidant and anti‐inflammatory functions and endorses a positive effect of lycopene on cardiovascular system.

The Russian Acute Coronary Syndrome Registry (RusACSR) is a retrospective, continuous, nationwide, Web‐based registry of patients with acute coronary syndromes (ACS). The RusACSR is a database that uses a secure Web‐based interface for data entry by individual users. Participation in the RusACSR is voluntary. Any clinical center that provides health care to ACS patients can take part in the RusACSR. The RusACSR enrolls ACS patients who have undergone care in Russian hospitals from February 2008 to the present. Key data elements and methods of data analysis in the RusACSR are presented in this article. Up to 2015, 213 clinical centers from 36 regions of Russia had participated in the RusACSR. Currently, the database contains data on more than 250 000 ACS patients who underwent care from 2008 to 2015. Some current problems are highlighted in this article. The RusACSR is a perspective project for different epidemiologic studies in Russian ACS patients.

Цель. Определить эффективность вакцинации против гриппа у пациентов с болезнями системы кровообращения (БСК), находящихся под диспансерным наблюдением в поликлинике, по данным трехлетнего проспективного наблюдения. Материал и методы. Проведено исследование эффективности вакцинопрофилактики гриппа у лиц с БСК, находящихся под диспансерным наблюдением в 2 поликлиниках г. Иваново и в 2 поликлиниках г. Саратова по данным трехлетнего проспективного контроля. Включено в ис-следование 817 человек, из них согласившихся на вакцинацию противогриппозной вакциной Гриппол плюс было 367 (44,9%) пациентов, а отказавшихся -450 (55,1%). Через 1 год и через 2 года повторно пришли на визит 778 и 747 пациентов, соответственно. После получе-ния согласия проведена вакцинация, соответственно 42,9% и 41,8% из них. При этом количество трижды вакцинированных пациентов со-ставило 286 человек (77,9% от числа исходно вакцинированных), число трижды не вакцинированных -379 (84,2%). Результаты. В течение 36 мес после включения в исследование в группе вакцинированных выявлено достоверно меньшее, чем у не вакци-нированных, число инфекционных событий (228 и 442, р<0,0001). В группе вакцинированных было достоверно меньше число случаев ухуд-шения БСК на одного пациента (р=0,04), меньше число госпитализаций по поводу БСК (р=0,006) по сравнению с не вакцинированными. Суммарное число случаев инфаркта миокарда (ИМ), мозгового инсульта (МИ), смерти от БСК в группе вакцинированных было достоверно меньше (17), чем у не вакцинированных (38), р=0,03. Риск развития инфекционного заболевания и острого сердечно-сосудистого ослож-нения (ИМ, МИ, смерть от БСК) был достоверно ниже в группе вакцинированных: на 36% (р=0,001) и 59% (р=0,008), соответственно. Заключение. Вакцинопрофилактика гриппа у лиц с БСК, являясь важной составляющей комплексной медицинской профилактики, приве-ла по данным трехлетнего проспективного диспансерного наблюдения к снижению частоты случаев, как инфекционных заболеваний, так и ухудшения клинического течения БСК, включая развитие острого ИМ, МИ и фатального исхода.Ключевые слова: болезни системы кровообращения, грипп, острые респираторные вирусные инфекции, вакцинопрофилактика, проспек-тивное наблюдение.
