Abstract
The exertional dyspnea is a specific symptom of the heart failure and an important prognostic factor. The estimation of the oxygen consumption at the peak of the effort and at the anaerobic threshold lets on the exact and objective estimation the efficiency of the circulatory system. Patients with heart failure have the increase of the frequency of breaths and symptoms of the hyperventilation inadequate to the effort. Accompanying diseases have significant influence on the prognosis of the heart failure, they make difficult recognition of heart failure and change the way of the treatment. Ergospirometry is the most objective estimation of the patient with the exertional dyspnea: the estimation of the degree of the heart failure, the differential diagnosis of the etiology of the exertional dyspnea, the estimation of the efficiency of the cardiological and pneumonological treatment.
