View issue in PDF

• Dear readers!

  Our Journal’s quest for scientific frontiers leads to publications on hot topics in research, and the current Journal issue is supporting this general rule. Following this way, we are presenting hereby one of the hottest themes: Cardiology in Oncology. In this connection, it should be mentioned that it has been just Cardiometry that has been capable of assessing toxicity actions and effects produced both by a malignant tumor and anticancer therapy on the human hemodynamics and the cardiac muscle metabolic processes using the most advanced noninvasive Cardiocode device & technology. The pilot studies associated with these challenging research topics have been conducted by Russian researchers at the Rostov Research Institute of Oncology, Rostov-on-Don, Russia.

  Cardiotoxicity: a challenge for modern oncology

  Oleg I. Kit, Elena M. Frantsiyants, Elena A. Dzhenkova, Yuriy А. Fomenko, Vladimir S. Trifanov, Aleksey N. Shevchenko

  The article provides a modern vision of the problem of cardiotoxicity in oncology. Integrity and generality of nodal pathogenetic events in the body in case of carcinogenesis, antitumor therapy and cardiopathology are caused by similar mechanisms at different hierarchical levels. Identity of potential risk factors, including inflammation, aging, obesity, diabetes and smoking, has been noted.

  Cardiometry in oncology: new digital possibilities for analyzing the cardiovascular system state in cancer patients

  Lyubov Y. Vladimirova, Lyudmila Y. Rozenko, Nailya К. Guskova, Larisa N. Vaschenko, Marina А. Gusareva, Vitaly I. Voshedsky, Inna V. Pavlyatenko

  The new high-tech era begins not with supply of an innovative product to the market, but rather with an intellectual leap in the field of open issues in fundamental engineering, healthcare and education. In the present essay, an example of the successful translation of mathematical, physics- and engineering-related philosophy into the digital platform of Cardiometry is discussed. The theory of hemodynamics, the laws of axiomatics, logic and adaptation can be expressed in terms of mathematics. The original analytical software used in PC-assisted device Cardiocode allows carrying out a phase analysis of the hemodynamics within an extended range.

  Effect of slow coronary flow on signal-averaged electrocardiogram

  Hossein Nough, Elahe Rafiei khoshnood, Aryan Naghedi, Leila Hadiani, Mohammad Vahid Jorat

  The slow flow coronary or decreased coronary TIMI flow rate is characterized by delayed pacification of coronary vessels in the absence of any evidence of obstruction coronary artery disease and is detected by coronary angiography. In the present study, we aimed to evaluate the effects of slow coronary artery flow on signal-averaged electrocardiogram (SAECG) as a possible indicator of increased risk for ventricular arrhythmias and sudden cardiac death.

  Assessment of the efficacy of a peroral anticoagulant after surgical resection of gastric cancer

  Igor I. Katelnitsky, Maksim N. Duritsky, Petr N. Gabrichidze, Viktoria R. Zakharchenko, Yuriy А. Przhedetskiy, Sergey I. Poluektov, Alla V. Pustovalova

  Patients suffering from gastric cancer have a high risk of postoperative thrombotic complications and often use anticoagulants. Direct oral anticoagulants absorb in the proximal region of the digestive tract. Consequently, a reduction in anticoagulating activity is possible. In the present research given is an evaluation of the anti-Xa activity upon administration of Rivaroxaban at a fixed dose of 20 mg once daily in oncological patients after gastrectomy or cases of extensive resection of the stomach.

  Functional state of the blood coagulation system in postsurgery period in patients with malignant tumors of the GI tract

  Kristina А. Avanesova, Dmitry S. Petrov, Sergey N. Dimitriadi, Yulia N. Krokhmal, Ekaterina О. Vasilieva

  The present paper analyzes changes in coagulation system markers in 64 patients with malignant tumors of the GI in surgical treatment. Results obtained when using parameters of the expanded coagulogram and a new global hemostatic assessment test with the use of Thrombodynamics recorder T2 have been evaluated. Based on the findings, we have developed models for predicting postoperative venous thrombosis and compared different methods for the coagulation system examinations.

  Ruptured mycotic hepatic artery aneurysm associated with methicillin sensitive staphylococcal endocarditis

  Hamidreza Varastehravan, Hasan Salmanroghani, Aryan Naghedi

  Hemobilia is a rare cause of upper gastrointestinal hemorrhage. Classical presentations of hemobilia are biliary colic, jaundice, hematochezia and melena. Persistent bleeding sometimes requires urgent therapeutic intervention, such as angiographic intervention or surgery. It may be secondary to trauma, inflammatory disorders, gallstones or tumors. Hepatic artery aneurysm rupture is a rare cause of gastrointestinal bleeding.

  A brief analysis of the use of non-linear time-frequency filtering for processing ECG signals

  Yeldos A. Altay, Artem S. Kremlev

  Some current trends of the use of non-linear time-frequency filtering approach to ECG signal processing are discussed herein. A brief review of an application potentiality of non-linear filtration is offered for long-term ECG signal processing. Possible problems of long-term monitoring, related to measurements interference and noise of ECG signal, are revealed. To eliminate the revealed problems, in further research, an implementation of a processing system using the non-linear-threshold time-frequency filtering method is planned. It is expected to improve an accuracy of cardiac data processing considering features of interference and measurement noise of different intensity.
