Exercise training, as the core component of a Pulmonary Rehabilitation program, may help restore arterial blood flow in the lungs of patients who had suffered Pulmonary Embolism (PE), stimulating and promoting vasodilator effects, repairing the damaged endothelium and recruiting new blood vessels and also inducing a net fibrinolytic balance. Besides, exercise training could have a positive effect on quality of life of these patients.
An experimental multicenter study is proposed , randomized according to parallel assignation and blinded to third ones to evaluate the effect of a 10-weeks structured exercise-based intervention protocol on the restoration of lung blood flow after an acute PE.
Main objective is to compare the efficacy and safety in terms of quantitative measures from lung scintigraphy, of lung perfusion versus usual care in patients with PE. Additionally the study is aimed to identify bio-markers of response to treatment (mRNAs, MPs and proteomic approach) and to analyze the effects of training on exercise capacity, quality of life parameters and anxiety depression scores.
