[Sudden cardiac death and decompensation of heart failure: how to reduce the risks. A review].

The main causes of death in patients with heart failure (HF) are sudden cardiac death and decompensation of HF, especially with a low left ventricular ejection fraction. The prediction and prevention of risk factors for the development of these conditions are important goals both for guideline-directed medical therapy and for electrophysiological treatment methods. The article presents an overview of clinical studies devoted to the study of implantable cardioverter defibrillators in the prevention of sudden cardiac death, highlights the issues of monitoring the course of HF. Special attention is paid to multisensory monitoring in implantable devices equipped with a unique set of sensors for early diagnosis of the development of HF decompensation. It is expected that the practical use of such devices will reduce the number of exacerbations and hospitalizations for HF by detecting signs of threatening decompensation of blood circulation before the appearance of active symptoms, and as a result will reduce mortality in this category of patients.
