Clinical Utility of the PHQ-2 and GAD-2 in Pulmonary Hypertension

Patients with chronic thromboembolic pulmonary disease (CTEPD) without resting pulmonary hypertension (PH) frequently experience dyspnea which is not explained by stationary assessment and therefore requires cardiopulmonary exercise testing for further diagnostic insight.

Pulmonary artery pressures (PAPs) often become abnormal during exercise in patients with systemic sclerosis (SSc). This study sought to determine whether exercise-induced pulmonary hypertension (EIPH) assessed by exercise stress echocardiography (ESE) would be associated with subsequent increases in resting PAPs in patients with SSc.

Accurate resting oxygen consumption (rVO2) quantification is critical for Fick-derived cardiac output calculations. 

Remote 6-min walk testing (6MWT) has been shown to be safe in pulmonary hypertension, but limited data exist on its longitudinal durability and relationship to supervised in-clinic testing.
