Iron deficiency (ID) in patients with heart failure (HF) is a factor for unfavorable course and prognosis of the disease. The significance of ID in the diagnosis and treatment of HF has previously been demonstrated by multiple studies and meta-analyses. Therapy for ID in patients with HF is one of the most relevant and discussed issues. The use of intravenous iron medicinal products for the treatment of ID is currently being actively studied in patients of various categories; attempts are being made to specify the indications for use to produce the greatest effect on the prognosis and quality of life of HF patients.

AIM: To determine the effect of dapagliflozin therapy on myocardial remodeling and fibrosis according to magnetic resonance imaging (MRI) with contrast in patients with chronic heart failure (CHF) and atrial fibrillation (AF). MATERIALS AND METHODS: In the group of 22 patients with a combination of CHF and AF we analyzed the dynamics of remodeling parameters and assessed myocardial fibrosis during 6-month therapy with dapagliflozin according to cardiac MRI with contrast. RESULTS:   After 6 months of dapagliflozin therapy there was a statistically significant increase in LVEF (27 [23-32]-32 [26.5-36.5] p-0.04) and a tendency to decrease volume and linear dimensions of LV, LP. There was no progression of myocardial fibrosis according to the results of cardiac MRI with contrast in patients with HFrFV and AF. CONCLUSIONS: Dapagliflozin therapy in patients with HFrEF and AF led to favorable myocardial remodeling changes.

Aim    To compare electrocardiographic parameters and characteristics of myocardial contractility by echocardiography data in patients with chronic heart failure (CHF) with low left ventricular ejection fraction (LV EF) and atrial fibrillation (AF).Material and methods    The study included 66 patients with CHF and LV EF ≤40%. Electrocardiography was used to assess the QRS complex duration, QRS fragmentation, frontal QRS-T angle (fQRS-Ta), and 3D vectorcardiographic parameters, including the planarity of QRS loop, and the spatial QRS-T angle (sQRS-Ta). Echocardiography assessed LV EF, global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE).Results    Statistically significant correlations between electrocardiographic parameters and LV EF were not found. The presence of QRS fragmentation was associated with impaired GLS, higher GWW values, and lower GWE. A number of weak but significant correlations was observed: GLS worsened with increasing QRS duration, fQRS-Ta, and sQRS-Ta and decreasing QRS planarity index; GWW increased with increasing QRS duration; GWI, GCW, and GWE decreased as the QRS planarity index decreased. GWI decreased with increasing sQRS-Ta; GCW decreased with increasing fQRS-Ta and sQRS-Ta; GWE decreased with increasing QRS duration, fQRS-Ta and sQRS-Ta.Conclusion    Correlations were found between indicators of myocardial electrical remodeling and parameters of myocardial contractility, strain, and performance in CHF patients with low LV EF and AF. Further study of these parameters may be promising for assessing the severity of changes in myocardial structure and function in patients with various cardiovascular pathologies.

AIM: To explore the features of vectorcardiograms (VCG) of patients with essential hypertension complicated by chronic heart failure with reduced left ventricular ejection fraction (CHFrLVEF). MATERIALS AND METHODS: We analyzed VCGs of 70 hypertensive patients with CHFrLVEF and 275 hypertensive patients without clinical signs of CHF and with LVEF50%. We assessed the presence of rhythm and conduction disturbances, and the parameters of the synthesized VCG, i.e., module of the maximum QRS vector, planarity index of the spatial QRS loop (P/S), and spatial angle between the integral QRS and T vectors (sQRS-Ta). RESULTS: In hypertensive patients with CHF, certain conditions were detected more often as compared with hypertensive patients without CHF, i.e., atrial fibrillation (AF) in 52.9% vs 5.1%; p0.0001, and left bundle branch block (LBBB) in 38.6% vs 0.4%; p0.0001. The module of the maximum QRS vector and sQRS-Ta were significantly greater and P/S was significantly less in VCGs of patients with CHF. ROC-analysis showed that the presence of AF and LBBB just as VCG parameters assessed in this study provide clear discrimination between hypertensive patients with or without CHF both in the group as a whole and in the subgroups (1) without LBBB, (2) with sinus rhythm, and (3) with AF. sQRS-Ta was the most informative parameter (threshold 137, sensitivity 91%, specificity 92%). The P/S indicator at the optimal threshold value 0.92 was characterized by lower specificity (68%) with rather high sensitivity (79%). CONCLUSION: AF, LBBB, increased module of the maximum QRS vector and sQRS-Ta, and decreased P/S index are present in hypertensive patients with CHFrLVEF as compared with patients without CHF.

AIM: To evaluate the efficacy, safety and effect on the prognosis of cardiac contractility modulation (CCM) in patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction and atrial fibrillation compared with the group of only optimal drug therapy (ODT) of the 12-month follow-up. MATERIALS AND METHODS: Patients (n=200) were sequentially included in two groups: group 1 patients with CHF who are on ODT in combination with implanted CCM devices (n=100), group 2 comparison patients with CHF who receive only ODT (n=100). Initially and after 12 months, 12-channel electrocardiography (ECG), transthoracic echocardiography, daily ECG-monitoring, determination of the level of NT-proBNP, a six-minute walk test and an assessment of the quality of life according to the Minnesota Questionnaire were performed. RESULTS: In the CCM therapy group, a significant clinical improvement was revealed, which was expressed in the form of a decrease in functional class CHF by NYHA (New York Heart Association), an increase in the distance of a six-minute walk test and an improvement in the quality of life according to Minnesota Questionnaire, as well as an improvement in left ventricle contractile function compared to the ODT group. The absence of a proarrhythmogenic effect of the CCM was shown. There was a significant decrease in the frequency of the readmission due to CHF and the probability of achieving the combined endpoint in the CCM therapy group compared with only ODT. CONCLUSION: The use of CCM in patients with CHF and atrial fibrillation is an effective and safe method of therapy that leads to the development of reverse remodeling of the myocardium, improves the clinical status of patients and reduces the frequency of readmission due to decompensation of CHF.

Obesity is an independent predictor of cardiovascular diseases (CVD), including heart failure (HF). Nevertheless, numerous studies have shown that patients with CVD who are overweight and slightly obese have a better short-term and moderate prognosis than thinner patients with CVD. This phenomenon has been called the obesity paradox. Understanding the obesity paradox is important in patients with HF, given the high prevalence of obesity in patients with HF. The article presents an overview of clinical studies devoted to the study of obesity as a risk factor for HF, the pathogenesis of HF in obesity, and highlights the issues of the obesity paradox and the treatment of obesity in this category of patients.

AIM: To study of the features of the clinical course and prognosis in patients with chronic heart failure with low ejection fraction (HFrEF) and atrial fibrillation (AF) depending on the width of the QRS complex. MATERIALS AND METHODS: We studied the case histories of 514 patients (aged 60.213.84 years, 78% men) with HFrEF, hospitalized at the Chazov National Medical Research Center of Cardiology (Moscow) for the period from Jan 1, 2017 to Dec 31, 2018. Patients were divided into 2 groups depending on the duration of the QRS complex. RESULTS: Clinical and statistical retrospective analysis of the medical histories of patients with HFrEF, depending on the QRS duration, showed the predominance of patients with a QRS complex size of less than 130 ms (60.7%). In HFrEF, the expansion of the QRS complex is accompanied by an increase in the rate of readmission in patients with sinus rhythm (p=0.004). In patients with AF, the rehospitalization rate is significantly higher than in sinus rhythm and does not depend on the QRS duration (p=0.001). The incidence of unfavorable outcomes increases in connection with the addition of AF, which is most likely a more significant risk factor than QRS width. CONCLUSION: These results highlight that patients with AF and a narrow QRS complex have the same poor prognosis as those with a wide QRS complex and require the close attention of cardiologists.

Iron deficiency is frequent in patients with chronic heart failure (CHF) with a prevalence of 50%, and its frequency varies depending on the study groups. The presence of iron deficiency limits erythropoiesis, leading to the development of anemia over time in patients with CHF, regardless of gender, race, and left ventricular ejection fraction (LVEF). Observational studies demonstrate a higher prevalence of iron deficiency in women and in patients with higher NYHA (New York Heart Association) functional class, decreased LVEF, increased brain natriuretic peptide (NT-proBNP), or increased high-sensitivity C-reactive protein. Iron deficiency and anemia in patients with CHF are independently associated with a decreased exercise capacity, hospitalizations for CHF, an increase in overall mortality and mortality from cardiovascular diseases. The clinical significance of iron deficiency requires the need to diagnose iron metabolism in all patients with CHF. Current guidelines for the diagnosis and treatment of CHF indicate the need to determine the level of ferritin and saturation of transferrin in all patients with a suspected diagnosis of heart failure. The use of oral iron therapy in patients with CHF demonstrates its low efficacy in correcting this condition according to the clinical trials. At the same time the use of intravenous iron therapy is safe and improves symptoms, exercise capacity and quality of life in patients with heart failure with reduced ejection fraction and iron deficiency, which has been shown both in international placebo-controlled trials and meta-analyses. The use of iron carboxymaltose should improve CHF symptoms, exercise capacity and quality of life in patients with CHF and LVEF45%. Intravenous iron therapy has also been shown to reduce readmissions for CHF in patients with an LVEF50% who have recently been hospitalized for worsening CHF.

Aim      To analyze echocardiographic parameters that reflect left ventricular (LV) myocardial contractility, using a novel method for evaluation of myocardial performance in patients with chronic heart failure (CHF) and atrial fibrillation (AF) during heart contractility modulation (HCM).Material and methods  Standard echocardiographic parameters and indexes of myocardial strain and work were analyzed for 66 patients (52 men and 14 women; median age, 60 [54; 66] years). 36 patients had paroxysmal AF and 30 patients had permanent AF. All patients had CHF with a duration of 17 [4; 60] months; duration of AF was 12 [6; 36] months. At baseline, the left ventricular ejection fraction (LV EF) was 33 [27; 37] %.Results After one year of HCM, LV EF significantly increased from 33 [27; 37] to 38 [33; 44] % (р=0.001). Also, there were improvements in the myocardial global longitudinal strain (from -6.00 [ - 8; - 4] to -8 [ - 10; - 6] %; р=0.001) and parameters of myocardial work, including the global work efficiency (from 74 [65; 79] to 80 [73; 87] mm Hg%; р=0.001), global constructive work (from 699 [516; 940] to 882 [714; 1242] mm Hg%; р=0.001), and global myocardial work index (from 460 [339; 723] to 668 [497; 943] mm Hg%; р=0.001). A segmentary analysis of LV work parameters showed positive changes in the myocardial constructive work in the area of the interventricular septal apical segment (at baseline, 844 [614; 1224]; after HCM, 1027 [800; 1520] mm Hg%; р=0.05) and the medium segment of the LV anteroseptal wall (at baseline, 593 [312; 1000]; after HCM, 877 [494; 1145] mm Hg%; р=0.05).Conclusion      This method for analysis of the myocardial work provides a more detailed examination of LV structural and functional remodeling and mechanisms for its effects on the LV contractile function in patients with CHF. This method is promising and merits further study in various clinical situations.

AIM: To study the effect of cardiac contractility modulation on reverse remodeling and myocardial function in patients with chronic heart failure (HF) according to echocardiography (EchoCG). MATERIALS AND METHODS: In a group of 40 patients with a combination of chronic HF and atrial fibrillation (AF), the dynamics of standard EchoCG parameters and the effectiveness of myocardial work of the left ventricle (LV) against the background of 12-month therapy of cardiac contractility modulation (CCM) were analyzed. RESULTS: The results obtained indicate a statistically significant positive effect of CCM on LV remodeling parameters and the effectiveness of myocardial work according to EchoCG. CONCLUSION: Transthoracic echocardiography is the main imaging method and provides great opportunities for evaluating the effectiveness of HF treatment, including non-drug methods such as CCM. Evaluation of LV myocardial function in patients with HF and implanted CCM devices is a promising scientific and practical research method.

Atrial fibrillation (AF) is associated with significant morbidity and mortality and may lead to the development of chronic heart failure (CHF). Each condition predisposes to the other, requiring a careful choice of the treatment strategy. This article is devoted to the prevalence and prognostic implications of both diseases. The article presents data from meta-analyzes related to the management of this group of patients. The aspects of rhythm control strategy in AF and concomitant CHF are described according to the recent studies and clinical guidelines. The features of anticoagulant therapy in patients with AF and CHF are outlined. Much attention is given to the importance of the safety profile of the anticoagulant therapy in terms of the bleeding risk in patients with concomitant AF and CHF.

AIM: To evaluate the dynamics of cardiac arrhythmias on the background of cardiac contractility modulation (MCC) in patients with chronic heart failure (CHF) and various forms of atrial fibrillation (AF) on the basis of daily electrocardiogram (ECG) monitoring. MATERIALS AND METHODS: In 100 patients with CHF and AF, the following studies were performed before implantation of the MCC device and after 12 months of follow-up: 12-channel ECG with an estimate of the width of the QRS complex, transthoracic echocardiography (EchoCG), and Holter ECG monitoring. All patients received long-term optimal drug therapy for CHF before surgery. RESULTS: The results obtained indicate that there is no effect of MCC on the development and progression of ventricular arrhythmias in patients with CHF and AF during the year of follow-up, both extrasystole and tachyarrhythmias, regardless of the etiology and LVEF (less than 35% or more than 35%), and a decrease in the frequency of AF paroxysms in patients with CHF during treatment. These results are due to the reverse remodeling of the LV myocardium under the influence of the MCC device. CONCLUSION: The use of MСС in patients with CHF and AF is a safe method of therapy that does not induce cardiac arrhythmias, including ventricular extrasystole. Large-scale comparative studies are required to evaluate these results.

AIM: to evaluate the effectiveness of cardiac contractility modulation (MSS) in patients with chronic heart failure (CHF) and atrial fibrillation (AF). MATERIALS AND METHODS: The following studies were performed in 40 patients with CHF and AF before implantation of the MSS device and after 2 and 6 months of follow-up: 12-channel ECG, transthoracic EchoCG, 6-minute walk test, determination of the level of Pro-natriuretic N-terminal peptide (NT-proBNP), daily ECG monitoring, and a questionnaire based on the Minnesota quality of life questionnaire for patients with CHF (MHFLQ). All patients received long-term optimal drug therapy for CHF before surgery. RESULTS: The results obtained indicate a statistically significant positive effect of the use of MSS in patients with CHF and AF on LV FV, the functional class of CHF, and levels of NT-proBNP regardless of the etiology of CHF. CONCLUSION: The use of MSS may be promising for the treatment of heart failure in patients with CHF and AF.

OBJECTIVE: The timely diagnosis of atrial fibrillation (AF) in patients with cardiac embolism with implantable loop recorders (ILR). MATERIAL AND METHODS: Twenty-nine patients, hospitalized within 6 months after stroke (n=19) or transient ischemic attack (n=10), were included in the study. ILR were implanted in all cases. The mean time of follow-up was one year. RESULTS: Five hundred and thirteen transmissions were detected during the whole follow-up period. Symptomatic episodes were recorded in 165 cases. Such episodes as bradycardia, asystole, AF, atrial tachycardia and ventricular tachycardia were recorded in 98 cases out of 348 planned transmissions. All transmissions were analyzed by an operator. However, 70 cases were false-positive because of ILR over-sensing. In total, arrhythmias were detected in 5 patients, including sick sinus syndrome (1), supraventricular tachycardia (1), ventricular tachycardia (1) and atrial fibrillation (3). Anticoagulant therapy was started immediately after the diagnosis of AF. CONCLUSION: Loop recording monitoring is an effective strategy in patients with cardiac embolism for timely diagnosis and further treatment of arrhythmia.

Heart failure is one of the main health care problems all over the world. Although, there are many drugs with proven effectiveness and hi-tech devices, there is a continuous process of searching new possibilities in heart failure prophylaxis going on because of huge economic burden and impact on life quality. Developing of atrial fibrillation in heart failure patients increases the risks of hospitalization and all-cause mortality. Appearance of new Optimizer Smart® system of cardiac contractility modulation is a perspective way of treatment in patients with heart failure and atrial fibrillation, who are not a candidate or have not got a good result from cardiac resynchronization therapy (CRT).

Takayasu arteritis belongs to the group of systemic vasculitis with a predominant lesion of large - caliber vessels and the development of stenosis of their lumen. In world practice, to establish the diagnosis of arteritis Takayasu apply the criteria proposed by the American College of rheumatologists. Currently, there are no randomized clinical trials related to the disease, and the diagnosis and treatment of patients are based on a number of small studies, a series of clinical cases and expert opinion. The described clinical observation of a patient with Takayasu arteritis is of interest in connection with the detected atrial myocarditis during MRI diagnosis of the heart with contrast, which allows us to discuss the feasibility of this imaging technique in complex and doubtful cases.
