A model for economic freedom on Mars

The momentum of human spaceflight initiatives continues to build toward Mars, and technological advances may eventually enable the potential for permanent space settlement. Aspirations for sustaining human life in space must be predicated on human factors, rather than technological constraints alone, and advances in models of governance and ethics are necessary as human civilization becomes a spacefaring species. This paper presents an idealistic but feasible model for economic freedom on Mars, which is situated within a framework in which Mars has been designated as a sovereign juridical peer to Earth. Under such conditions, Mars could maintain monetary stability through full reserve banking and a restriction on exchange with any fractional reserve Earth currencies, with a volume of circulating currency that changes based on the total population within fixed capacity infrastructure. Mars could maintain long-term political stability by diffusing the ownership of capital on Mars, which would allow all citizens of Mars to draw sufficient wealth from a combination of capital ownership and labor to live a good life. This model could also support limited tourism on Mars, in which real goods are exchanged for services but currency transactions between planets are prohibited. This model demonstrates the potential for a viable and sustainable economy on Mars that could conceivably be implemented, including on a sovereign Mars but also in other scenarios of space settlement. More broadly, this model illustrates that ideas such as diffuse capital ownership and limited government can enable freedom in space, and numerous models beyond a centralized world space agency should be explored to ensure the optimal governance of the emerging space economy.

Manifestations of Infringement on the Public Authority's General Jurisdiction in Currency Issuance and Management from an Islamic Perspective

Objectives: This study aims to identify and analyse the forms of infringement on the sovereign right of public authority in the issuance and management of currency, particularly in the context of the fractional reserve banking system and the technological advancements facilitated by globalisation, which have enabled the creation and promotion of virtual currencies. Methodology: The study adopts a composite method that combines historical induction and logical reasoning to explore the forms of infringement on the general jurisdiction of the authority associated with both traditional and emerging forms of currency. Findings: The study concludes that safeguarding public authority's exclusive and disinterested right in currency issuance and management is a priority in Islamic legal policy. Such necessitates caution against forms of infringement that violate this right due to their impact on the fairness and efficiency of the monetary system. Originality: This research's originality lies in its characterisation of the generation of credit money and the issuance or mining of virtual currencies as contemporary forms of infringement on the authority's general jurisdiction, akin to the counterfeiting of paper money.

High Powered Money in India-An Empirical Analysis

High powered money in the sum of commercial bank reserves and currency (notes and coins) held by Public. High powered money in the base for the expansion of bank deposit and creation of money supply. Thus high powered money H=C+RR+ER. Where C represents currency with the public, RR the required reserves in the commercial banks and ER the excess reserves with banks. High powered money also known as the monetary base. In India the Reserve Bank of India is responsible for regulatory and controlling the monetary base. It is important to note that the composition and dynamics of high powered money in India can change over time due to shifts in monetary policy, economic conditions, and changes in banking regulations. High powered money plays a fundamental role in monetary system. It serves as the base upon which the broader money supply (M1, M2 etc) is created through the process of fractional reserve banking. When banks make loans, they create deposits, effectively increasing the broader money supply. The RBI uses various tools, such as open market operations and reserve requirement, to control the growth of high powered money and, consequently the money supply to achieves its monetary policy objectives, such as controlling inflation and promoting economic growth.

Implementation of Minimum Mandatory Giro (Gwm) in Sharia Banking Perspective Analysis of Siyasah Syar'iyyah Maliyyahtitle

This research analyzesthe implementation of Mandatory Reserve Requirement (GWM) in Islamic banking in Indonesia, with a focus on the duplication of money resulting from the implementation of GWM in Islamic banking, the regulation of GWM in Islamic banking in the view of Siyasah Syar'iyyah Maliyyah, and finding a more just system solution for GWM regulation in Islamic banking in Indonesia. In this research, the researcher used a qualitative research method with a library research type and a philosophical approach. The results of this research show that GWM is a monetary instrument applied by the central bank to ensure the liquidity and solvency level of banks in the financial system. The purpose of implementing GWM is to ensure that banks have enough funds to handle their liquidity needs and to ensure the stability of the overall financial system. Then, the perspective of Siyasah Syariyyah Maliyyah shows that the implementation of Islamic economics in Indonesiamust be practiced according to the socio-cultural conditions in Indonesia. Currently, GWM is something that cannot be avoided, and there is still no new system that can replace it for Islamic banks. Therefore, GWM in Islamic banking is one of the monetary instruments that can control inflation. The existence of GWM in Islamic banking in the concept of Maslahah is at the level of tahsiniyat (tertiary). The debate over the existence of GWM in Islamic banking presents several solutions to provide justice for all parties, including changing the fractional reserve banking system to Narrow Banking, which clearly distinguishes between savings and deposits, emphasizes the principle of amanah, and separates profit-making activities in banking through cooperation with separate affiliate organizations from the bank itself. Because the fractional reserve banking system has been challenged in Switzerland, the solution to GWM gharar is the sovereign money system, which is similar to full reserve coverage, but goes further by giving full control over deposits seen by the central bank. So there is no gharar element. In other words, existing savings "create" loans

Association between contrast-enhanced adenosine-stress perfusion cardiac magnetic resonance imaging and invasive coronary angiogram for the detection of coronary artery disease: A retrospective analysis.

The objective of this study was to determine the diagnostic value of stress perfusion CMR for the detection of coronary artery disease. The was a retrospective cross sectional study in which 43 subjects were included from Cardiac MRI unit in the Hayatabad Medical Complex, Peshawar for study from 1st April 2020 to 30th November 2020. All the subjects who had been referred for stress perfusion CMR with suspected CAD were included in the study. Cardiac MRI both at rest and with adenosine stress perfusion was performed which was followed by invasive coronary angiography. A total of 43 patients were enrolled for the detection or exclusion CAD who underwent stress perfusion CMRI and invasive coronary artery angiography. The study revealed strong and statistically significant association between positive stress perfusion CMR and positive coronary angiogram vs negative stress perfusion CMR and negative coronary angiogram (p= value 0.0001). Stress perfusion CMRI can be considered as a first line, relatively safe, noninvasive test with significant accuracy to diagnose coronary artery disease in patients with suspected CAD without subjecting these patients to invasive coronary angiogram.

Intravascular Imaging versus Physiological Assessment versus Biomechanics-Which Is a Better Guide for Coronary Revascularization.

Today, coronary artery disease (CAD) continues to be a prominent cause of death worldwide. A reliable assessment of coronary stenosis represents a prerequisite for the appropriate management of CAD. Nevertheless, there are still major challenges pertaining to some limitations of current imaging and functional diagnostic modalities. The present review summarizes the current data on invasive functional and intracoronary imaging assessment using optical coherence tomography (OCT), and intravascular ultrasound (IVUS). Amongst the functional parameters-on top of fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR)-we point to novel angiography-based measures such as quantitative flow ratio (QFR), vessel fractional flow reserve (vFFR), angiography-derived fractional flow reserve (FFRangio), and computed tomography-derived flow fractional reserve (FFR-CT), as well as hybrid approaches focusing on optical flow ratio (OFR), computational fluid dynamics and attempts to quantify the forces exaggerated by blood on the coronary plaque and vessel wall.

Money Multiplication in Islamic Banking – A Discussion on its Impact on Distributive Justice

This paper explores the legitimacy of the use of Fractional Reserve System in Islamic banking from the normative premise of Islamic economics. The paper uses a methodology of structured literature review and a conceptual analysis of the literature following the approach of Critical Interpretive Synthesis (CIS). The first section of the paper presents the analysis on fractional Reserve Bank (FRB) system, how it leads to multiplication of money supply and influence the long-term inflation and business cycles; the second part of the article explains the extent to which this framework obstructs in the achievement of the objectives of Islamic Economics. This is followed by a reflective analysis of concepts and information gathered from the literature to evaluate how FRB system fits into the fabric of Islamic Economic. The second section of this paper explains how Islamic Banks, with an FRB model and its inclination towards debt-based instruments, would allow Islamic banks to contribute to the problem of inflation, even if they use Musharakah and Mudarabah as a mode of finance.

A critical legal analysis of commercial bank money

Because of the role that commercial banks play in today’s financial and banking system, this article discusses the activity of commercial banks with regards to how money (commercial bank money) is created. By exploring the nature of the fractional reserve banking system, this article establishes that commercial banks are not mere financial intermediaries, but rather exclusive money creator. A critical legal analysis of this money creation process concludes, with solid supporting arguments, that commercial bank money is riddled with legal violations and harmful socioeconomic effects, which are inevitably borne by the individual and society in the form of ‘privatizing the profits of money creation’ and ‘socializing the losses and its outrageous financial burden’.

Does PLS in Islamic banking limit excessive money creation?

PurposeBank lending is the major source of monetary expansion. Bank-led money creation is a key issue in both conventional and Islamic financial systems. The purpose of this paper is to examine the issues related to Islamic banking money creation. In this conceptual paper, the authors investigate the involvement of profit and loss sharing (PLS) in money creation and especially how can PLS limit money creation “out of nothing.” In this regard, the authors examine the potential of the PLS principle in tackling the excessive money creation phenomenon.Design/methodology/approachThis study uses a normative approach regarding Islamic bank money creation that fits Sharia directives. In fact, this study discusses “what ought to be,” that is, the values and norms of PLS money creation that impede excessive money creation.FindingsOverall, Islamic banks create money differently compared to conventional ones. Especially, by avoiding a purely financial intermediary, money creation under the PLS principle sustains a strong relationship with the real economy and leads to a lower money multiplier. Therefore, PLS mechanisms allow financing through real assets and not credit assets “out of nothing.” This could prevent excessive money creation from causing harmful effects on indebtedness and financial instability.Practical implicationsPLS offers a valuable resolution for banking system money creation through the optimization of Islamic bank financing by facilitating the separation of the monetary function from the credit one. This reform thought reinforces the stability value of money allowing it to fully perform its functions with reference to the directives of Sharia. This especially allows the integrity and purchasing power of money, the reduction of the gap between the evolution of both real and financial economies and, consequently, the indebtedness and crisis. It is recommended to promote PLS financing by reforming institutional and regulatory constraints.Originality/valueThis study addresses the contemporary issue of money creation by Islamic banks through the PLS approach. The conceptual framework of this paper highlights the reformist role of PLS in limiting money creation through Mudarabah approach within fractional reserve banking.

CFD Computation of Flow Fractional Reserve (FFR) in Coronary Artery Trees Using a Novel Physiologically Based Algorithm (PBA) Under 3D Steady and Pulsatile Flow Conditions

A novel physiologically based algorithm (PBA) for the computation of fractional flow reserve (FFR) in coronary artery trees (CATs) using computational fluid dynamics (CFD) is proposed and developed. The PBA was based on an extension of Murray's law and additional inlet conditions prescribed iteratively and was implemented in OpenFOAM v1912 for testing and validation. 3D models of CATs were created using CT scans and computational meshes, and the results were compared to invasive coronary angiographic (ICA) data to validate the accuracy and effectiveness of the PBA. The discrepancy between the calculated and experimental FFR was within 2.33-5.26% in the steady-state and transient simulations, respectively, when convergence was reached. The PBA was a reliable and physiologically sound technique compared to a current lumped parameter model (LPM), which is based on empirical scaling correlations and requires nonlinear iterative computing for convergence. The accuracy of the PBA method was further confirmed using an FDA nozzle, which demonstrated good alignment with the CFD-validated values.

CONVENTIONAL RESULTS OF UNCONVENTIONAL MONETARY POLICY

The financial crisis of 2008 was a major crisis after 1929. It reminded once again us about the contradictory nature of fractional reserve Banking. The Great Depression taught us that the financial crisis of 2008 would result in a substantial reduction in economic activity and a sharp deterioration of key economic indicators. To "avoid" recessionary risks, the Federal Reserve System and other central banks of developed countries actively adopted monetary easing measures. A large amount of money was injected into the credit system. At the initial stage, the "explanation" of the mentioned measure was liquidity and recession risks. However, the time has shown us that the number of “colored papers" does not create wealth, it only distributes it in favor of those who have the privilege to "spend" it first, until a quantitative increase of money will be reflected in prices. As expected, the unconventional monetary policy gave very conventional results: inflation, stagnation, and an overheated credit system. The results would be more unambiguous without the Russia-Ukraine war, which affected inflation in the EU. The results of the monetary experiment conducted after the financial crisis of 2008 and its consequences, once again showed us that finance does not create wealth, it only promotes, distributes, and insures it. Therefore, every attempt to improve the picture of the real economy with monetary interventions is futile and cannot change the final result. With monetary interventions, it is only possible to postpone the consequences of the crisis, at the expense of their aggravation and intensification.

Assessment of hemodynamic significance of renal artery stenoses in endovascular treatment of resistant vasorenal arterial hypertension

Objective. To determine the significance of renal artery stenosis according to different methods of assessing the functional significance of stenosis and to evaluate the safety and efficacy of stenting of unilateral renal artery stenosis after 6 months and 1 year according to office BP and ABPM.Materials and methods. The study included 44 patients with resistant arterial hypertension and renal artery stenosis (mean age 69 ± 11 years), while receiving multicomponent antihypertensive therapy, including diuretic. After assessing the degree of RA stenosis according to selective angiography and additional methods of assessing the functional significance of RA stenosis (iFR, Pd/Pa, translesional gradient and FFR) the patients underwent RA stenting. The safety of the procedure was assessed by creatinine and glomerular filtration rate dynamics (MDRD equation). The effectiveness of the procedure was study according to office blood pressure (BP) and ambulatory BP monitoring (ABPM).Results. According to the results of angiography, the patients were divided into two groups: group A – patients with subtotal PA stenosis (> 90%) and group B – patients with moderate stenosis (60-90%), who underwent additional assessment of the functional significance of stenosis. The immediate angiographic result in both groups was optimal (the degree of residual stenosis was less than 5%). In group B, after stent implantation in the PA, there was a decrease of the translesional gradient by 38 ± 10 mm Hg (p < 0,0001), FFR > 0,8(p < 0.0001). iFR > 0.89, Pd/Pa>0.9 (p = 0,093). In both groups, there was a significantly significant reduction in arterial blood pressure at distant times, according to clinical BP measurement and ABPM.Conclusion. The measurement of such parameters as translesional gradient and fractional reserve is the most reliable in assessing the hemodynamic significance of PA stenosis in comparison with iFR and Pd/Pa measurements in patients with moderate PA stenosis. PA stenting in patients with uncontrolled resistant AH and severe renal artery lesions, as well as moderate stenosis confirmed by additional methods of stenosis functional significance assessment is reasonable to consider in order to enhance the antihypertensive effect.

Providing an Islamic approach of monetary systems

PurposeThe purpose of this paper is organized as follows. Section 2 reviews the literature on the subject matter, focusing on western economic literature and the Islamic economic paradigm, including the Quran, Sunnah, jurisprudence and Islamic philosophy thinking, to illustrate the origins of the Islamic approach to monetary systems. The money interest rate and its studies are explained, and the role of money and credit in the production function is considered. Then, it is shown that money maintains the demand for money in the overlapping generation model, as well as the consumption behavior of households. It is followed by an explanation of general Pareto optimality and the role of the money interest rate in inefficiency and nonoptimality for households and firms. Finally, Section 4 concludes the paper.Design/methodology/approachThis paper studies the effects of money issuance and bank creation on Pareto optimality. In explaining the origins of the Islamic approach to monetary systems, the literature review, it focuses on western economics’ literature and Islamic economics paradigms such as the Quran, sunnah, jurisprudence and Islamic philosophy thinking. In modeling section, the authors show how banks’ fractional reserve credit is profitable. The authors also examine how the introduction of the money interest rate can change the Pareto optimality. In this regard, the comparison between two situations, namely, financing by the stock of money and borrowing in the credit market, indicates that welfare is reduced by the creation system and is inefficient (or nonoptimal). The result is that no money and no credits are created. The provision of this system compensates money by increasing the real money supply or deflation. To ensure Pareto optimality, it has been proven in the field of microfoundation that there should be no fixed money contracts and no money interest rates. It is necessary that the interest rate on consumption credit is zero or Qarz-al-Hasna is broken. Moreover, profit sharing is offered in the production sector.FindingsAs a result, the authors proved mathematically that the money interest rate must be zero to ensure productivity and Pareto optimality. On the other hand, the introduction of money or credit through loanable money leads to inefficiency, both in production and households and in the general equilibrium. The inflation generated by the credit system stimulates the change in the price level and perpetuates this inefficiency. Thus, if the authors want to return to the optimality condition, the interest rate on consumption credit must be zero or Qarz-al-Hasna is breached. However, the behavior of the fractional banking system and the credit mechanism teaches us that the money interest rate is an integral part of credit and loanable funds. Thus, the elimination of the money interest rate from the banking system without bank creation is implausible. Finally, to ensure Pareto optimality, it has been mathematically proven in the field of microfoundation that there should be no fixed money contracts and no money interest rate. It is necessary that the interest rate on consumption credit is zero, or Qarz-al-Hasna is broken. Moreover, profit sharing is offered in the production sector. The result is that no money and credit are created. The provision of this system compensates money by increasing the real money supply or deflation.Originality/valueThe capitalist theory of the definition of interest plays a decisive role in economic science. In this context, the authors are dealing with different vocabularies and terms for the interest rate. These different vocabularies have their origin in the different economic situations and especially determine the thinking of the schools. Because of the relationship between future and spot, the authors have to transform the variable “level” into the variable “interest rate” in the dynamic space. Finally, the exact explanations for the movement and evaluation of the economy are revealed by the correlation of the different interest rates.

To Study the Impact on the Perception of Banking Customers toward E-Banking (A Case Study of Jk Bank Customers)

Modern banking practices, including fractional reserve banking and the issue of banknotes, emerged in the 17th and 18th centuries. Merchants started to store their gold with the goldsmiths of London, who possessed private vaults and charged a fee for that service. The study sought to determine the impact on the perception of J&K bank customers with emerging Modern Banking. The study adopted a Descriptive research design on a sample size of 150 respondents in which 75 respondents were Men and 75 were women respondents which makes our research more sound and concrete, who were selected through Convince Sampling Technique (due to shortage of time because it was a project that requires a lot of time) from a target population of 1500 consisting both men and women, Government employees and self employed and married as well as unmarried which made our research more fruitful. It was concluded that the emerging the Bank was not able to change the perception of the J&K bank customers. The customers of the Bank still consider this Bank as a sound financial Institution for investment, they are also ready to be the customers of this in the future as well, and they also recommend others to avail the facilities from the J&K Bank, which shows the faith and trust on the Bank. They were not impressed by all the modern schemes and policies adopted by the new banks in the State. They are fully satisfied with the services and facilities provided by the Bank. It proved our set hypothesis wrong which was Emerging new banks have changed the perception of J&K bank customers. Finally, it was revealed that the customers of this have the same perception and Image of this Bank as a Universal bank.

Contract Theory, Title Transfer, and Libertarianism

In the present paper we argue that the theory of contracts embraced by many libertarian scholars and relied upon by them in sundry important debates (e.g. over morality of the fractional reserve banking or loan maturity mismatching etc.), that is, the title transfer theory of contracts (TTT) should be rejected as not being able to account for the binding force of future-oriented contracts, including contracts deemed enforceable by those scholars themselves. The TTT claims that the only contracts that should be legally binding are these where the debtor’s failure to abide by them constitutes a violation of the creditor’s private property rights. However, as we argue, no default of the debtor in a future-oriented contract can in itself amount to such a violation.

CENTRAL BANK DIGITAL CURRENCY EFFECTS ON FRACTIONAL RESERVE BANKING

An aim of the paper is to explore the outlines of the looming monetary order. For these purposes, we have made a brief retrospective analysis of money genesis. In its inception market had selected gold as a medium of exchange and gold had become a social institution. After WWII the leading force of monetary order changed. The Bretton Woods conference had made a political agreement to endorse the US dollar as a reserve currency. In 1971 the picture had become clearer, and the gold-backed dollar system collapsed as it was predicted earlier. A digital environment has given the reborn of new types of money. The pioneer of digital money was the crypto currency, a decentralized and transparent system to pay and hold the value. As the old saying tells, everything new is well forgotten old one. Since 2021 central Bank of China has launched a digital RMB pilot program. It is easy to grasp that the state tries to substitute the market-developed money (crypto currencies) with the monopolistic system of CBDC. We have found out the effects of CBDC on retail banking and the incapability of CBDC monetary order with fractional reserve banking.

A Further Clarification of Ludwig von Mises as a Currency School Free Banker

This article refutes the view that Ludwig von Mises proposed freedom in banking as the most suitable means to render the issue of additional fiduciary media completely impossible and shows why Mises’s proposal should not be credited as such. Following in Joseph T. Salerno’s footsteps, this article interprets Mises’s thoughts in light of the nineteenth-century debate between the currency and banking schools in Britain. It finds that Mises’s free banking theory incorporates theoretical insights from both sides and as such represents an incomplete resolution to the old debate and presages the ultimate split in modern literature on free banking. This article also addresses the law of reflux of the banking school within Mises’s free banking theory. After a critical exposition on the law of reflux, it is revealed that the actual and common employment of standard sound money in exchange and cash holding is fundamental in order for the law to serve as a strong restriction on the supply of fiduciary media in a fractional reserve free banking industry.

Long-term results of percutaneous coronary interventions in patients with diffuse and multivessel coronary artery diseases

Highlights. Two-year results of stenting in patients with diffuse and multivessel coronary artery lesions performed using intravascular research and control methods (optical coherence tomography, blood flow fractional reserve) are presented. A low incidence of myocardial infarction, repeated interventions and a high level of survival, free from significant cardiovascular complications, were noted when using intravascular research methods in patients during percutaneous coronary intervention in comparison with the patients who did not undergo intravascular methods.Aim. To evaluate the two-year results of percutaneous coronary interventions (PCI) in patients with diffuse and multivessel coronary lesions.Methods. 128 patients were included in the study and divided into two groups. In group I (n = 62) PCI was performed using intravascular imaging methods, in group II (n = 66) no intravascular imaging methods (retrospectively) were used. The measurement of fractional flow reserve (FFR) in diffusely altered arteries was performed against the background of maximum hyperemia between stenoses by pulling the sensor starting from the distal segment. Initially, the most distal hemodynamically significant stenosis underwent the stenting. Then, a repeated measurement of FFR was performed and it showed if the further stenting was needed. The results of stenting, as well as the determination of the stent implantation area were carried out by the method of optical coherence tomography.Results. 12 months after PCI the results of treatment were checked in all patients and after 24 months – in 106 patients (56 and 50, respectively, in groups I and II). The achievement of complete (functionally adequate, according to FFR measurements) myocardial revascularization was achieved in 93.5% of patients from group I, while the result in the control group was only 56% of patients. The average number of stenoses in the target non-occluded artery according to angiography and after FFR measurement was the following: in patients with two-vessel lesions – 2.95±0.65 and 1.82±0.88, respectively, and in patients with three-vessel lesions – 2.96±0.6 and 2.24±0.76, respectively (p = 0.0024). After 12 months of follow-up, significant differences were observed between groups I and II in the frequency of myocardial infarction (1.8 and 4.0%, respectively; χ2 = 5.172) and repeated interventions (3.6 and 16.0%, respectively; χ2 = 8.114). By the 24th month of follow-up, among the observed patients, the total frequency of myocardial infarction, repeated interventions and cardiac death were significantly higher in patients of group II compared with group I and they were 45.5 and 9.6%, respectively (χ2 = 14.784; p<0,0001).Conclusion. Long-term results of PCI in patients with diffuse and multivessel coronary lesions using intravascular imaging methods (optical coherence tomography and FFR measurements) are characterized by low cardiac complications, compared with patients operated without imaging methods.

The Role of Fractional Flow Reserve in Interventional Treatment of Multivessel Coronary Artery Disease

Selective coronary angiography (CAG) is an invasive diagnostic method for the assessment of the internal lumen and anatomical features of the coronary artery. This is a routine procedure and the basis for choosing the tactics of management of patients with coronary artery disease (CAD). However, CAG is a two-dimensional imaging, and despite the use of the poly projection imaging, there may be difficulties in assessing of the degree of stenosis (even by experienced operators, especially in 50–70% lesions). Along with multivessel disease (stenostes of 2 or more main coronary arteries with a diameter of more than 2 mm), this may cause difficulties in interpreting the results of the study and choosing further volume of revascularization (the number of treated stenosis). In these cases, it is necessary to use a combination of CAG with additional functional methods for diagnosing the significance of each coronary stenosis and its role in the occurrence of myocardial ischemia.
 The aim. To analyze the clinical results of stenting with invasive measurement of fractional flow reserve when choosing the volume of revascularization of 50–70% coronary artery stenoses.
 Materials and methods. The results of interventions in 109 patients treated at the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine from 2017 to 2022 with CAD were studied; in these patients, CAG revealed >50–70% multivessel coronary artery disease. They were divided into two groups: fractional reserve group (main group) undergoing stenting of only symptomatic stenosis according to intracoronary physiological examination (n = 52; 47%), and control group (anatomical revascularization, n = 57; 53%) where stenting was determined according to angiography.
 Conclusion. Interventional treatment of multivessel CAD with fractional flow reserve assessment enables to avoid inappropriate stenting of hemodynamically insignificant stenoses, thus it is possible to optimize treatment tactics of this group of patients (reduce the number of implanted stents).
