Stroke volume, heart rate and ventricular ejection fraction at rest and peak-exercise for each subject group: Systemic Sclerosis (SSc); Systemic Sclerosis-associated Pulmonary Arterial Hypertension (SSc-PAH); Non-Connective Tissue Disease Pulmonary Hypertension (NC-PAH); Healthy controls. A Stroke volume indexed to body surface area. B Heart rate (HR). C Right ventricular ejection fraction (RVEF)*. D Left ventricular ejection fraction (LVEF). Normally distributed data displayed as mean ± SD. *Denotes non-normally distributed data shown as median (range)
