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. ⋯ 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.

Cardiovascular and respiratory diseases have been one of the leading causes of mortality in the world for over 15 years. According to the results of various studies, a clear connection was revealed between the incidence of influenza and the decompensation of cardiovascular diseases, which leads to the development of acute coronary syndrome, acute heart failure and myocardial infarction. ⋯ Influenza vaccination, especially in patients with high cardiovascular risk, is one of the most important secondary prevention measures. The article is dedicated to an overview of the problems of vaccination against influenza, the study of the prognosis of patients with high cardiovascular risk, as well as general points in the pathogenesis of influenza and cardiovascular diseases.

Multicenter Study
[Characteristics of patients with chronic thromboembolic pulmonary hypertension according to the Russian National Registry].
To assess demographic and clinical characteristics, to describe of the functional and hemodynamic status, profile of concomitant pathology, data of instrumental examination in chronic thromboembolic pulmonary hypertension (CTEPH) patients; to study the features of specific and supportive therapy according to the data of the Russian national registry. ⋯ According to the Russian registry, inoperable CTEPH patients had precapillary PH (pulmonary hypertension) with severe functional status, in combination with frequent concomitant pathology (arterial hypertension, erosive-ulcerative lesions of the stomach/duodenum, atrial fibrillation, obesity, right heart failure). 66% of inoperable CTEPH patients received specific drug therapy.

Currently, the world is constantly increasing the number of people with obesity. As was shown by the Framingham study, obesity is a risk factor for many cardiovascular diseases. The effect of obesity on the structure and function of the heart is manifested in the form of cardiac remodeling, the effect on energy metabolism in the heart and infiltration of both myocardium with lipids, and an increase in the accumulation of adipose tissue in the pericardium, imbalance of adipokines and activation of inflammatory markers. ⋯ It is not fully known whether obesity is associated with systolic dysfunction, regardless of other risk factors. In any case, it has been proven that heart failure in people with obesity can develop independently of other risk factors. As an illustration, we give an example when the presence of obesity and concomitant pathology (arterial hypertension, diabetes) led to the development of systolic dysfunction with a decrease in the LV ejection fraction to 35% (fat cardiopathy), which show the potential for the influence of both obesity itself and in combination with concomitant diseases to lead to severe systolic heart failure.

The authors report the clinical case of secondary Takotsubo syndrome developed after transcatheter aortic valve replacement that was performed in compassionate manner in female patient with combination of congenital ventricular septal defect and acquired severe aortic stenosis. In the teams view, Takotsubo syndrome was triggered with profound changes of intracardial hemodynamics subsequent to iatrogenic impairment of preexisting interventricular shunt.
