To explore the features of vectorcardiograms (VCG) of patients with essential hypertension complicated by chronic heart failure with reduced left ventricular ejection fraction (CHFrLVEF). ⋯ 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.

Are presented the key aspects of the management of patients with acute decompensation of heart failure leading to improved clinical outcomes. Are described the existing problems and possible solutions.

[Remote electrocardiogram telemonitoring after endovascular interventions on the coronary arteries].
To evaluate the effectiveness of a new system for telemetric electrocardiogram (ECG) monitoring in patients after endovascular interventions (EI) on the coronary arteries (CA). ⋯ Carrying out telemetric ECG-monitoring after EI on the CA improves the quality of observation after the procedure, promotes early discharge of patients, makes the intervention more comfortable and safe. The introduction of this technique into clinical practice will make it possible to more widely use the outpatient approach when carrying out EI, and to increase the turnover of specialized beds and the efficiency of the work of medical institutions.

The vector concept in the analysis of the electrical signals of the heart began to be used at the dawn of the development of electrocardiology. For several decades, vectorcardiography has developed in parallel with electrocardiography; reached its peak in the 60s, and after a period of cooling experienced a resurgence since the early 90s, when it became possible to mathematically synthesize vectorcardiograms (VCG) from digital electrocardiograms in 12 leads. ⋯ The article describes the main milestones in the development of the VCG, the history of international cooperation in this area, the contribution of domestic scientists to this field of science. Modern promising areas of research related to the vector concept of the analysis of the electrical signals of the heart are briefly reflected.

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. ⋯ 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.
