Disproportionate Exercise-Induced Pulmonary Hypertension in Relation to Cardiac Output in Heart Failure with Preserved Ejection Fraction: A Non-Invasive Echocardiographic Study

Abstract

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.
