Transient subendocardial ischemia in nifedipine abolition of hypertensive crises

Sublingual nifedipine, 30 mg, was used to abolish hypertensive crises in 32 patients. A follow-up of changes in blood pressure, ECG, and echocardiographic parameters evaluating the cardiac performance and central hemodynamics was performed during 4 hours after the drug. The patients with profound myocardial hypertrophy and dilatation at a left ventricular myocardial weight of over 200 g at the peak of the antihypertensive effect occurred for 15-60 min exhibited transient ECG changes by the type of subendocardial ischemia despite an above 25% reduction in mean blood pressure and the lack of severe reflex tachycardia, the pump function of the heart showing no decreases. The ejection fraction increased from 51.0 ± 2.8 to 62.0 ± 2.5% (p < 0.05) due to lower afterload. There were no clinical manifestations typical of myocardial ischemia

Financial risks of Russian oil companies in conditions of volatility of global oil prices

The development of scientific approaches to assessing and diagnosing the financial risks of oil industry in the Russian Federation becomes a high priority task in conditions of high level of volatility in oil prices in the world energy market and preservation of sanctions regime. The article shows the main threats to financial stability of oil companies in Russia. Using cluster analysis, a system of indicators is proposed that determines the level of financial risk of oil companies in Russia. Based on the method of expert assessments and fuzzy sets, the classification of financial risk levels of oil industry is proposed. The integrated financial risk level of oil industry was calculated and scenarios of its development for 2018-2020 were forecast by means of regression modeling. The system of measures to improve the stability of oil companies and prevent functional financial risks is argued. The practical implementation of research results will be the basis for timely diagnosis of financial risks and qualitative development of preventive measures to neutralize them in the oil industry of Russia. © 2019, Econjournals.

Improving the economic performance of Russia’s energy system based on the development of alternative energy sources

An upward trend in conventional energy consumption and the exhaustibility of its resources, volatility of the prices for hydrocarbons in the global energy market update the development of scientific approaches to justification of the commercial efficiency of alternative energy in the Russian Federation. Integrated economic performance and environmental safety coefficients for generating companies in Russia were calculated through taxonomic analysis. Trends in the expenditure level for energy production in the context of alternative and conventional energy resources were forecasted by means of neural modeling technologies. Using an integrated assessment method, global priorities for the use of energy resources in Russia that would enhance the national energy system operation efficiency were identified. A forecasting integrated model of the Russian energy system development was elaborated, taking into account the commercial efficiency of alternative energy. Measures to stimulate energy production based on the use of alternative energy sources were proposed. Practical implementation of the research findings would contribute to Russia’s energy system restructuring and meeting the energy needs of the national economy to the fullest extent possible. © 2018, Econjournals.
