Study suspended due to COVID-19 pandemic

INTRODUCTION: The complexity of the pathophysiology of heterogeneous diseases such as heart failure and obstructive pulmonary disease causes a different approach to these diseases or with a view as much as a better understanding of the same situations, with which the clinical profile of patients who are associated with an association is. It is known that regular physical training promotes progressive improvements in exercise tolerance, in the pulmonary ventilation / perfusion ratio and in respiratory function by strengthening. OBJECTIVE: To compare the effects of high-intensity interval training and continuous aerobic exercise, with peripheral endothelial function, brain natriuretic peptide levels, maximum exercise tolerance, distribution of lung volumes and quality of life of patients with obstructive pulmonary disease associated with heart failure. METHODS: This is a clinical, controlled, randomized and blinded trial. Peripheral endothelial function, tolerance to maximum and submaximal exercise, distribution of lung volumes, quality of life, presence of symptoms of depression and perception of clinical change will be evaluated. EXPECTED RESULTS: Incorporate into the care of these patients, new effective therapeutic approaches, of low cost and with greater technical and scientific evidence.
