Summary

Although there has been some progress in pharmacological management of PAH, limited functional capacity and low survival still persist, but there is evidence that exercise training can be accomplished without adverse effects or damage to cardiac function and pulmonary hemodynamics. Specifically, improvements in symptoms, exercise capacity, peripheral muscle function and quality of life. Training programs need to be better studied and well defined, and their physiological effects during physical training and functional capacity. The aim of this study is to compare the effects of different training exercises on physical performance indicators.

Detailed description

Pulmonary arterial hypertension (PAH) is characterized by pathological changes in the pulmonary vasculature which cause an increase in pulmonary vascular resistance (PVR), restricting the flow of blood through the pulmonary circulation. It is a serious illness, progressive and usually fatal which causes significant functional limitation, mainly due to dyspnea. In order to maintain the flow of blood, pulmonary artery pressure (PAP) increases and the disease progresses leading to right ventricular dysfunction and right heart failure. Regardless of the cause of PAH, the pulmonary arteries and arterioles have reduced capacity, and increases in cardiac output during exercise is limited. As a result, the delivery of oxygen to peripheral muscles is impaired, contributing to the symptoms of fatigue and dyspnea. While the limitation of the cardiac output to meet peripheral oxygen demand during exercise largely reduces exercise capacity, musculoskeletal dysfunction may also be involved in the exercise limitation in patients with PAH. Changes such as, muscle atrophy, decreased oxidative enzymes and a greater number of type II muscle fibers lead to an early lactic acidosis and decreased functional capacity. A modest evidence exists that exercise training can be done without adverse effects or damage to cardiac and / or pulmonary hemodynamics however, the effectiveness PAH requires more research.
