Dyspnea is a major complaint of both chronic obstructive pulmonary disease (COPD) and heart failure with preserved ejection fraction (HFpEF). It often remains underdiagnosed in COPD patients when only echocardiography at rest is performed. The aim of this study was to evaluate the predictive value of cardiopulmonary and echocardiographic parameters at rest for the diagnosis of HFpEF in non-severe COPD patients who complain of exertional dyspnea and have no overt cardiovascular disease.
