Alterations of heart rhythm are a common clinical event. They can be caused by almost any kind of heart disorder. ⋯ Prevalence of AF in the general population is 1-2%, and given that AF incidence rate continues to increase it can be predicted that the number of patients will be doubled within the next 50 years. This review provides the most recent diagnostic and treatment methods, including both unique domestic antiarrhythmic drugs and non - drug methods for AF treatment which were developed and implemented in clinical practice at NMRC of Cardiology of the Ministry of Health of the Russian Federation.

It has been established that an increased fibroblast growth factor (FGF-23) serum levels significantly contribute to the heart and blood vessels remodeling in patients with chronic kidney disease (CKD). But the precise mechanisms of the FGF-23 cardiac effect are currently being actively studied. At the same time, it is believed that the cardiac effects of FGF-23 may be due to the increasing deficit of Klotho protein as CKD progresses. In parallel with these changes, a number of studies indicate the persistence of the detectable troponins serum levels in CKD patients, even in the absence of clear clinical manifestations of cardiovascular diseases (CVD). The aim of the study was to confirm / exclude the existence of a causal relationship between elevated FGF-23, reduced Klotho and elevated troponin-I (as the most specific troponin in CKD). ⋯ The changes in serum levels of FGF-23, Klotho and troponin-I (Tr-I) depended on the stage of CKD. The following correlations were identified: FGF-23 and: Tr-I (r=0.601; p.

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.

The article analyzes the publications devoted to the problem of professional renal lesions caused by chemical factors. Classification, prevalence, peculiarities of the clinical picture, diagnosis of professional renal lesions caused by chemical factors of the production environment are reviewed. The frequency of professional renal lesions remains underestimated due to low manifestation of symptoms and the influence of environmental factors, which require further investigation of this issue.
