Abstract
It is well known that congestive heart failure (CHF) patients show reduced maximal inspiratory pressure (PImax) and limited endurance of inspiratory muscles which limit the exercise response otherwise; cardiac resynchronization therapy (CRT) has become an established adjunctive treatment to optimal pharmacologic therapy in patients with advanced CHF, diminished Left Ventricular function and intra-ventricular conduction delay. Although CRT has been shown to improve ventricular hemodynamics, quality of life and exercise capacity. As the inspiratory muscle training (IMT) improves exercise capacity and ventilatory responses to exercise in CHF patients with inspiratory muscle weakness we assess the effect of IMT on ventilator functions, ejection fraction, functional state and quality of life on patients with CHF and whom underwent to CRT and we concluded that the IMT improve the ventilator functions, functional state and quality of life in patients with CHF and whom underwent to CRT otherwise the ejection fraction not improved with IMT for CHF patients but, it had improved with IMT for CRT group
