Abstract

Dyspnoea during daily physical activity, despite optimized and maximized drug therapy, is a phenomenon commonly observed in patients with chronic heart failure (CHF).The purpose of this study was to assess the usefulness of a period of rehabilitation in the control of dyspnoea in a group of patients with CHF. The worsening of symptoms may be related to changes in polmunary function parameterst. It has been evaluated their possible relationship with the systolic function and / or diastolic function of the left ventricle and assessed which parameter of polmunary function can be considered a predictor of acute cardiac events and mortality in these patients. Patients with CHF but without chronic obstructive pulmonary and with dyspnoea can provide a baseline a ventilatory pattern next to normal. The improvement of dyspnoea after rehabilitation in some patients is associated with a restrictive respiratory pattern due to a modification of polmunary function following a mechanism desufflation lung. This polmunary hyperinflation in patients with CHF may be the cause of dyspnoea and may mask the restrictive ventilatory pattern typical of these patients and predicting the increased mortality from any cause and hospitalizations for cardiovascular causes more than traditional predictors based on the study of systolic and diastolic function of left ventricle.
