Outcomes
Primary Outcome Measures
Change in Peak Power Index at Rest
The peak power index is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. The peak power index is calculated from the maximal power (which also takes the calculated parameter cardiac output into account) divided by the left ventricular end-diastolic volume (LVEDV). Formula: Peak Power Index = (SAPmean - PCWPmean)*CO [cardiac output]*16.667/LVEDV
Secondary Outcome Measures
Change in Left Ventricular Stroke Work Index (LVSWI) at Rest
The left ventricular stroke work index (LVSWI) is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. The LVSWI is also dependent of the calculated hemodynamic parameter stroke volume index (SVI). Formula: LVSWI = (SAPmean - PCWPmean)*SVI*0.0136
Change in Left Ventricular Ejection Fraction (LVEF) at Rest
The left ventricular ejection fraction work index (LVEF) is a calculated echocardiography parameter. LVEF is derived from the directly measured parameters left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV). These 2 parameters are acquired during a non-invasive echocardiography examination. Formula: LEVF = 100*(LVEDV - LVESV)/LVEDV
Change in End-systolic Elastance at Rest
The end-systolic elastance is a calculated hemodynamic parameter. It is approximated by the directly measured hemodynamic parameter end-systolic pressure divided by the directly measured echocardiography parameter left ventricular end-systolic volume (LVESV). The end-systolic pressure is acquired during a right heart catheterization. The LVESV is acquired during a non-invasive echocardiography examination. Approximated by end-systolic pressure/LVESV
Change in Peak Power Index During the Cardiopulmonary Exercise Tests
The peak power index is a calculated hemodynamic parameter. It is derived from the directly measured parameters mean systolic arterial pressure (SAPmean) and mean pulmonary capillary wedge pressure (PCWPmean). These 2 parameters are acquired during a right heart catheterization. Formula: Peak Power Index = (SAPmean - PCWPmean)*CO*16.667/LVEDV
Change in Lateral Mitral Annular Peak Systolic Velocity (Sm) During the Cardiopulmonary Exercise Tests
The lateral mitral annular peak systolic velocity (Sm) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.
Change in Peak Systolic Tricuspid Annular Velocity (RV-Sm) During the Cardiopulmonary Exercise Tests
The peak systolic tricuspid annular velocity (RV-Sm) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.
Change in Tricuspid Annular Plane Systolic Excursion (TAPSE) During the Cardiopulmonary Exercise Tests
The tricuspid annular plane systolic excursion (TAPSE) is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.
Change in Lateral Mitral Annular Peak Early Diastolic Velocity (E') During the Cardiopulmonary Exercise Tests
The lateral mitral annular peak early diastolic velocity (E') is a measured echocardiography parameter. It is acquired during a non-invasive echocardiography examination.
Change in the Slope of the Relationship Between Work Rate and Mean Pulmonary Arterial Pressure (PAPmean) During the Cardiopulmonary Exercise Tests
The slope of the relationship between work rate during cardiopulmonary exercise tests and PAPmean is derived from the directly measured hemodynamic parameter mean pulmonary arterial pressure (PAPmean). PAPmean is acquired during a right heart catheterization.
Change in the Ventilatory Efficiency (V'E/V'CO2) Measured From Baseline to the Anaerobic Threshold (AT) During the Cardiopulmonary Exercise Tests (CPET)
Ventilatory efficiency (V'E/V'CO2) and anaerobic threshold (AT) were parameters directly measured or derived by computed analysis from the spiroergometry system during the cardiopulmonary exercise test.
