Application of cardiopulmonary exercise test in patients with pulmonary arterial hypertension

Abstract

Cardiopulmonary exercise test is a combination of power increasing exercise and computer technology to measure the parameters of ventilation, circulation and gas exchange during body movement by real-time breathing monitoring.It can accurately detect exercise tolerance, cardiac reserve function and severity of disease in patients with cardiovascular and pulmonary diseases.Pulmonary arterial hypertension is caused by pulmonary artery disease, which leads to the increase of pulmonary artery pressure, pulmonary vascular resistance, right cardiac dysfunction, right heart failure, and eventually leads to death.The application of cardiopulmonary exercise test in patients with pulmonary arterial hypertension is summarized as follows. Key words: Cardiopulmonary exercise test; Pulmonary arterial hypertension; Application
