May indicate transient exercise-induced pulmonary edema in HF; hypothesis-generating and requires prospective validation before clinical adoption.
Does exercise induce changes in alveolar-capillary membrane conductance indicative of pulmonary edema in heart failure patients?
Exercise induces a decrease in alveolar-capillary membrane conductance in heart failure patients, suggesting the development of exercise-induced pulmonary edema, particularly in those with periodic breathing or severe disease.
Agostoni et al. (2003) studied this question.
