The evaluation of the results of the measures taken in the treatment of the patients with the chronic heart failure has the complex character with the possibility of the objectification for a period and in the context of the specialized care. In the situations where it is necessary to solve the alternative diagnostic problems, i.e. to choose one of two diagnostic hypotheses, the various computational recognition methods can be used. An alternative option for predicting the disease or controlling the patient compensation, including the outside of a medical institution, can be used a computational recognition method that is simple in the technical design and time–consuming, facilitating the work of a doctor in solving the alternative diagnostic tasks – a sequential diagnostic procedure based on the method of the sequential analysis by A.Wald. The use of the method is justified if it is necessary to monitor the dynamics of the changes in the patients not only in the hospital, but also in everyday life during the day, week, month, making a forecast, for example, of the probability of the rehospitalization in the different time periods. The determination of the treatment result using this method, for example, using the evaluated clinical and laboratory parameters, helps to objectively attribute the changes at the current time to one of the options – no changes, the improvement at a given errors level. Key words: chronic heart failure, circulatory insufficiency, evaluation of the treatment results, consistent diagnostic procedure, Wald's analysis.
