Does exercise stress echocardiography identify distinct pathophysiologic phenotypes such as disproportionate exercise-induced pulmonary hypertension in patients with HFpEF?
Exercise stress echocardiography is important for identifying disproportionate exercise-induced pulmonary hypertension as a distinct pathophysiologic phenotype in patients with HFpEF.
Patients with HFpEF and DEi-PH demonstrated distinct pathophysiologic features that become apparent only during exercise. These data suggest that DEi-PH is a pathophysiologic phenotype of HFpEF and reinforce the importance of exercise stress echocardiography for detailed characterization of HFpEF.
Saito et al. (Mon,) studied this question.
