Evaluation of the relationship of tricuspid regurgitation peak gradient/tricuspid annulus plane systolic excursion to exercise capacity, cardiac index, and ventilatory function during exercise in patients with COPD

Chronic obstructive pulmonary disease (COPD) is a global health problem and the third leading cause of death.1 The incidence of COPD is expected to increase in the coming decades owing to continued exposure to noxious substances and an aging population.2 COPD is characterized by shortness of breath, wheezing, coughing or excessive sputum production, resulting in poor health-related quality of life.1 Many patients with COPD experience progressive disease and deteriorated cardiovascular function.1 These patients tend to have exercise intolerance and higher mortality rates.
