The mortality in the Czech Republic related to this condition is high. The current treatment strategy consists of the administration of medication to patients, in order to attenuate the clinical manifestations of the disease and to influence the overall survival of patients suffering from this condition. Another treatment option is a mini-invasive procedure, with implantation of a pacemaker with biventricular stimulation, or transplantation of the heart. Despite these treatment options, the mortality of patients due to heart failure remains high, and new approaches are being studied for the diagnostics and treatment of heart failure. Factors that may play an important role in earlier diagnostics are miRNA. These molecules are located in the circulating blood. They are being described as suitable prognostic markers of heart failure, which may contribute to earlier diagnostics and bring a better understanding of processes going on in the human body.\n\nIn the study, the authors will take blood samples in order to analyze the presence of miRNA.
