ListOutcomeTime frameDescription
PrimaryPulmonary Vascular Resistance (PVR) Ratio of Week 12 to BaselineBaseline to Week 12
PVR ratio equals to Week 12 PVR / Baseline PVR. PVR represents the resistance against which the right ventricle needs to pump. PVR was calculated using the following formula: mean pulmonary arterial pressure (mPAP) - pulmonary artery wedge pressure (PAWP)/cardiac output (CO); where mPAP and PAWP were measured at end-expiration and CO was measured in triplicate using the thermodilution method.
SecondaryChange From Baseline to Week 12 in Mean Right Atrial Pressure (mRAP)Baseline to Week 12
mRAP was collected in the eCRF (electronic case record form). Right atrial pressure (RAP) is the blood pressure in the right atrium of the heart. Change from baseline to Week 12 in mRAP was measured at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in Mean Pulmonary Arterial Pressure (mPAP)Baseline to Week 12
mPAP was collected in the eCRF. The pulmonary artery pressure is a measure of the blood pressure found in the main pulmonary artery. Change from baseline to Week 12 in mPAP was measured at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in Pulmonary Arterial Wedge Pressure (PAWP)Baseline to Week 12
PAWP was collected in the eCRF. PAWP is pressure within the pulmonary arterial system when the catheter tip is 'wedged' in the tapering branch of one of the pulmonary arteries. Change from baseline to Week 12 in PAWP was measured at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in Cardiac Index (CI)Baseline to Week 12
CI was calculated as Cardiac Output (CO)/body surface area (BSA), where CO is Thermodilution Cardiac Output (Liters per minute \[L/min\]) and BSA (m\^2) equals to 0.007184\*weight\^0.425 (kilograms)\*height\^0.725 (centimeter). CI was represented in liters per minute per square meter (L/min/m\^2). Change from baseline to Week 12 in CI was measured at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in Total Pulmonary Resistance (TPR)Baseline to Week 12
TPR was calculated as mPAP/CO where mPAP is mean pulmonary arterial pressure and CO is cardiac output. Change from baseline to Week 12 in TPR was calculated at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in Mixed Venous Oxygen Saturation (SvO2)Baseline to Week 12
Mixed venous oxygen saturation measures the end result of oxygen consumption and delivery. Change from baseline to Week 12 in SvO2 was reported and measured at rest and no correction for multiple testing was applied.
SecondaryChange From Baseline to Week 12 in N-terminal Prohormone of Brain Natriuretic Peptide (NT-proBNP) LevelsBaseline to Week 12NT-proBNP levels in the blood are used for diagnosis of acute congestive heart failure (CHF) and may be useful to establish prognosis in heart failure.
SecondaryChange From Baseline to Week 12 in Participants World Health Organization (WHO) Functional Class (FC)Baseline to Week 12
WHO FC is a classification which reflects disease severity based on symptoms. WHO Functional Classification of pulmonary hypertension comprises of Class I (participants with pulmonary hypertension but without resulting limitation of physical activity), II (participants with pulmonary hypertension resulting in slight limitation of physical activity), III (participants with pulmonary hypertension resulting in marked limitation of physical activity) and IV (participants with pulmonary hypertension with inability to carry out any physical activity without symptoms). Change from baseline in WHO FC was reported. WHO FC was categorized as worsening (change greater than \[\>\] 0); improvement (change less than \[\<\] 0); or no change (change equals to \[=\] 0).
