Aim To study the condition of coronary vasculature by data of coronarography (CG) in patients with chronic ischemic heart disease (IHD) and arterial hypertension (AH) associated with stage 2-4 chronic kidney disease (CKD) and to evaluate the effect of a 12-week complex treatment with perindopril or with a combination of perindopril/amlodipine on changes in vascular wall stiffness, endothelial function, and structure and function parameters in this patient category after coronary stenting.Material and methodsr This study included 87 patients with chronic IHD and AH associated with stage 2-3 CKD for whom CG was performed due to ineffectiveness of the antianginal therapy. The patients were divided into three subgroups: subgroup 1 included 28 patients who received a conservative treatment with perindopril 10 mg/day; subgroup 2 consisted of 25 patients who underwent coronary stenting and were prescribed perindopril; subgroup 3 consisted of 34 patients who underwent stenting and were prescribed the perindopril/amlodipine combination. The reference group included 47 patients with IHD and AH with preserved kidney function. Anatomic and functional parameters of the heart, arterial stiffness, pulse wave velocity, cardio-ankle vascular index, augmentation index, central aortic systolic and pulse pressure, endothelium-dependent vasodilation, plasma concentration of endothelin-1 (ET-1), and plasma concentration of nitric oxide metabolites were evaluated at baseline and after 12 weeks of treatment.Results In patients with IHD, AH, and stage 2-3 CKD, arterial stiffness was more pronounced than in patients with preserved kidney function. Concentrations of ET-1 were significantly higher and levels of nitric oxide were lower in CKD. Supplementing the complex therapy with perindopril resulted in a considerable hypotensive effect in all subgroups, improvement of the kidney function, and positive dynamics of arterial stiffness and endothelial function. Changes in these parameters were more pronounced in patients after coronary stenting than in patients receiving only a conservative treatment. The use of perindopril/amlodipine following stenting exerted the most significant angioprotective and cardioprotective effect.Conclusion Patients with IHD and AH in combination with early CKD have pronounced impairment of the condition of arterial blood vessels and the heart. Addition of perindopril to the treatment not only exerted a hypotensive effect but also beneficially influenced mechanisms of progression of this combined pathology.

PURPOSE. To evaluate the effectiveness and safety of warfarin therapy using a clinical laboratory model of centralized monitoring of international normalized relationships, and direct oral anticoagulants in patients with atrial fibrillation in real clinical practice.MATERIAL AND METHODS. In a non-interactive prospective study, 661 atrial fibrillation patients were prescribed oral anticoagulants to prevent cardioembolic complications. The study included patients older than 18 years of age, with creatinine clearance at least 50 ml/min. Рatients were divided into 4 groups: 1 group of 120 people who took warfarin was observed in the conditions of centralized monitoring the international normalized ratio (INR), group 2 – 112 people– was taking Rivaroxaban, group 3 – 106 people– was taking Dabigatran, group 4 – 98 people took Apixaban. Formed 4 groups of patients were comparable in age, concomitant diseases, risks of thromboembolic and hemorrhagic complications.The follow-up period was 2 years from the date of prescribing.RESULTS. In patients who were observed in the clinical laboratory model of centralized monitoring of INR, the TTR was 69.4%. The groups did not differ in the number of thromboembolic complications (p>0.05). Warfarin had an advantage in the amount of large bleeding - 0.9% versus 3.6% taking rivaroxaban and 3.8% taking dabigatran (p = 0.044 and p = 0.035, respectively) without statistical significance for apixaban.CONCLUSION. The ratio of efficacy and safety of warfarin therapy can be successfully maintained at a satisfactory level using a centralized monitoring system of international normalized relationships. It allows you to get comparable treatment results with warfarin and direct inhibitors of blood coagulation factors in real clinical practice.
The article describes the clinical observation of LAA thrombosis in a 46-year-old patient with atrial fibrillation that first occurred during taking warfarin; discusses further management of the patient. Due to inefficacy of medical cardioversion (CV) and the need to restore sinus rhythm, electric CV was planned. Before the planned restoration of the rhythm, transesophageal echocardiography was performed and a thrombus in the LAA was detected. Given that the patient had been on adequate warfarin therapy for a long time, it was decided to prescribe a drug from the direct oral anticoagulants group dabigatran etexilate at a dose of 150 mg BID for 8 weeks. The control transesophageal echocardiographic examination showed evidence of complete lysis of thrombus.
1ФГБОУ ВО «Курский государственный медицинский университет» Минздрава России, Курск, e-mail: vbFpo@mail.ru Цель: изучить особенности эндотелиальной функции у больных бронхиальной астмой в сочетании с ожирением, обосновать критерии прогнозирования формирования у них легочной гипертензии, установить особенности течения при сочетании бронхиальной астмы с ожирением. Были изучены данные 3474 пациентов с различными фенотипами бронхиальной астмы в период с 2012 по 2016 гг., обратившихся за медицинской помощью в медицинские учреждения на территории Курской области. С целью оценки эндотелиальной функции определяли концентрацию уровня эндотелина-1 плазмы, изучали эндотелийзависимую вазодилатацию плечевой артерии при проведении пробы по Celermajer и соавт. (1992). На функцию эндотелия у больных бронхиальной астмой влияют тяжесть и фаза заболевания, а также наличие и выраженность ожирения. Степень выраженности эндотелиальной дисфункции коррелировала с параметрами функции внешнего дыхания, характеризующими бронхообструкцию, и с уровнем давления в малом круге кровообращения. Зарегистрирована прямая корреляционная зависимость между высоким уровнем эндотелина-1 и средним давлением в легочной артерии (r=0,31, p=0,025). Эндотелийзависимая вазодилатация плечевой артерии у пациентов с бронхиальной астмой и ожирением была 4,4±0,6%, что достоверно ниже среднего показателя в группе лиц с астмой без ожирения (5,6±0,8%). У данных пациентов выявлена положительная корреляционная зависимость между эндотелийзависимой вазодилатацией и снижением пиковой скорости выдоха (r=0,48, p<0,05), объемом форсированного выдоха за первую секунду (r=0,56, p< 0,01). Более чем у 90% больных бронхиальной астмой и ожирением возникает эндотелиальная дисфункция, диагностированная по повышению уровня эндотелина-1 в плазме, нарушению эндотелийзависимой вазодилатации плечевой артерии. Выраженность этих изменений нарастает с утяжелением бронхиальной астмы и сопутствующего ожирения. Высокий уровень эндотелина-1 в крови и нарушения эндотелийзависимой вазодилатации плечевой артерии могут иметь прогностическое значение для выявления риска развития легочной гипертензии у больных с бронхиальной астмой в сочетании с ожирением. Ключевые слова: бронхиальная астма; ожирение; эндотелиальная дисфункция; легочная гипертензия
The aim of this study is to measure the level of the endothelin-1 in blood samples and to assess vasoactive function of the endothelial in asthma patients with different phenotypes and to develop the methods of the objective assess of the ongoing treatment. Materials and methods. 119 asthma patients were separated into several phenotypes: patients with atopic asthma (60 pat); patients with ACOS (35 pat); asthma with obesity (24 pat). In all patients endothelium-dependent vasodilation and plasma level of endothelin-1 were assessed. Results. Endothelial dysfunction revealed in all asthma phenotypes. The highest level of the endothelin-1 shown in ACOS patients. In patients which achieved asthma control during three month of the anti-inflammatory therapy showed decreasing of the endothelin-1 level by 1,5 times in comparison with basic level (0,35 ± 0,06 fmol/ml and 0,64 ± 0,15 fmol/ml respectively, р < 0,01). But in patients with persistent symptoms and/or without lung function improvement the level of the endothelin-1 was not decreased significantly. Conclusions. Change of the functional conditions of the endothelial depend on the time and severity and phenotype of the asthma. The endothelin-1 level and the endothelium-dependent vasodilatation assess on the course of the treatment allow to reveal success of this anti- inflammatory therapy.
The aim of the research was to study the peculiarities of cardiac and pulmonary hemodynamics, the mechanisms of formation of endothelial dysfunction, as well as their correction with angiotensin converting enzyme inhibitor, Ramipril and angiotensin-II receptor blocker, Irbesartan, in patients with arterial hypertension (HTN) combined with bronchial asthma (BA). Design and methods . Altogether 80 patients with BA of moderate severity combined with HTN of 1, 2 degrees were enrolled in the study. The average age of the patients was 52,9 ± 4,2 years. The eligible patients were randomized for treatment with either Ramipril 5 mg/day or Irbesartan 150 mg/day in combination with bronchodilator inhalation and anti-inflammatory medications for BA (Formoterol/Budesonide 160/4,5 mcg 2 inhalations twice, Ipratropium bromide and Ambroxol through nebulizer devices). The program of instrumental examination included echocardiography (Aloka 1700, Japan; LOGIQ 500, Germany) with ultrasonic sensors of 3,5 MHz. The plasma level of endothelin 1 (ET‑1) was estimated by immune-enzyme assay (Biomedica set, category № 442–0052, Arkray, Japan). Results. Two-month monotherapy with Irbesartan allows to achieve the target blood pressure (BP), leads to the regression of cardiac remodeling and has a positive effect on endothelial function and bronchial patency. Conclusions. Irbesartan is able to provide a stable and reliable control of BP, and delays the progression of pathological cardiovascular changes; it has a favorable impact on the respiratory function, is well tolerated, easy to use, and may be considered as the best antihypertensive drug in patients with co-morbid HTN and BA.
