Measuring Outcomes In Patients With Pulmonary Arterial Hypertension Not on Active Treatment (MOTION)

The Living with Pulmonary Hypertension (LPH) questionnaire with Heart Failure questionnaire comprises 21 items, responded to on a 6-point Likert scale ranging from 0 'No' to 5 'Very much'. A total score ranging from 0 (best) to 105 (worst) is calculated by summing the responses to all 21 questions.

Functional class was determined by the WHO classification: I: Patients with PH (pulmonary hypertension) but without resulting limitation of physical activity. Ordinary physical activity does not cause undue dyspnea or fatigue, chest pain, or near syncope. II: Patients with PH resulting in slight limitation of physical activity. They are comfortable at rest. Ordinary physical activity causes undue dyspnea or fatigue, chest pain, or near syncope. III: Patients with PH resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary activity causes undue dyspnea or fatigue, chest pain, or near syncope. IV: Patients with PH with inability to carry out any physical activity without symptoms. These patients manifest signs of right-heart failure. Dyspnea and/or fatigue may even be present at rest. Discomfort is increased by any physical activity. In the below table, N signifies subjects who were evaluable for the specific parameter at that timepoint.
