Change in Left Ventricular End-diastolic Volume (LVEDV)
Left ventricular enddiastolic volume (LVEDV) is a measurement of the volume of blood in the heart's left ventricular chamber at the end of the chamber's filling with blood and will be determined as measured by MRI.
Time frame: Baseline, week 2
Change in Forced Expiratory Volume in One Second (FEV1).
Forced Expiratory Volume in one second (FEV1) will be calculated as the volume of air forcibly exhaled in one second as measured by spirometry.
Time frame: Baseline, week 2
Change in Forced Vital Capacity (FVC).
Forced Vital Capacity (FVC) is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC will be assessed via spirometry.
Time frame: Baseline, week 2
Change in Inspiratory Capacity (IC) at Each Time-point
Inspiratory capacity (IC) was defined as the mean of the maximum IC over 3 values measured by bodyplethysmography according to internationally accepted standards.
Time frame: Baseline, week 2
Change in Total Lung Capacity (TLC)
Total Lung Capacity (TLC) will be calculated from the mean Functional Residual Capacity (FRC) plus the highest value of the Inspiratory Capacity, both measured by body plethymography according to internationally accepted standards.
Time frame: Baseline, week 2
Change in Residual Volume (RVol)
Residual Volume (RVol) will be calculated from the value of Total Lung Capacity (TLC) minus the highest value of the Slow Vital Capacity, both measured by body plethymography according to internationally accepted standards.

Time frame: Baseline, week 2
Change in Specific Airway Resistance (sRaw)
Specific Airway Resistance (sRaw) will be documented as effective resistance (sReff) calculated as the median of five acceptable measurements. Values will be measured by body plethymography according to internationally accepted standards.
Time frame: Baseline, week 2
Change in Functional Residual Capacity (FRC)
Functional Residual Capacity (FRC) will be calculated as the mean of three reproducible values as measured by body plethymography according to internationally accepted standards.
Time frame: Baseline, week 2
Change in Right Ventricular (RV) and Left Ventricular (LV) Ejection Fraction (EF)
Right and left ventricular ejection fraction is the fraction of blood (in percent) pumped out of the heart's left and right ventricular chamber, respectively, with each heart beat and will be determined as measured by MRI.
Time frame: Baseline, week 2
Change in Left and Right Ventricular End-systolic Volume
Right ventricular end-systolic volume (RV-ESV) and left ventricular end-systolic volume (LV-ESV) is a measurement of the volume of blood in the heart's right and left ventricular chamber, respectively, at the end of the heart's contraction and will be determined as measured by MRI.
Time frame: Baseline, week 2
Change in Right Ventricular Enddiastolic Volume
Right ventricular end-diastolic volume is a measurement of the volume of blood in the heart's right ventricular chamber at the end of the chamber's filling with blood and will be determined as measured by MRI.
Time frame: Baseline, week 2
Cardiac Output at Each Time-point, Left and Right Ventricular Cardiac Output (LVCO and RVCO)
Cardiac output is calculated as the heart rate multiplied by the stroke volume (= difference between ventricular enddiastolic volume and endsystolic volume) that will be determined as measured by MRI.
Time frame: week 2
