The aim is to identify pulmonary vascular disease in post/long-COVID-19 patients as a cause of dyspnea/exercise limitation and to differentiate it from other causes of dyspnea (muscular, left cardiac, psychological, deconditioning-related causes) by investigating ventilation-perfusion (V/Q) mismatch and (exercise-induced) pulmonary hypertension (PH) or right heart dysfunction.
