Inclusion criteria
* Male or female * Age ≥ 18 years * Patients with definite diagnosis of SSc by American College of Rheumatology (ACR) criteria (18); including all patients with any other connective tissue diseases (CTD) who, in parallel, meet the ACR criteria for SSc (18) * SSc disease duration \> 3 years dated from onset of first non-Raynaud feature * Diffusing capacity of the lung for carbon monoxide (DLCO) \< 60% of predicted
Exclusion criteria
* PH confirmed by RHC before enrolment, i.e. mean pulmonary arterial pressure (mPAP) \> or = 25 mmHg at rest or \> or = 30 mmHg at exercise, independent of PCWP (11) * RHC within the 12 months before enrolment * Use of therapy that is considered definite PAH/PH treatment (19) for any indication, within the 6 weeks before enrolment and/or for a total of more than 6 weeks during the 12 months before enrolment: i.e. endothelin receptor antagonists (ERA; e.g. bosentan, sitaxsentan, ambrisentan), phosphodiesterase type 5 inhibitors (PDE5; e.g. sildenafil, tadalafil, vardenafil), prostanoids (e.g. epoprostenol, treprostinil, iloprost, beraprost), and any experimental PAH/PH drugs. Intermittent use of PDE5 inhibitors for male erectile dysfunction is permitted * Forced vital capacity (FVC) \< 40% * Renal insufficiency, defined as estimated glomerular filtration rate (eGFR) \< 40 ml/min/1.73 m2 (20), assessed according to local practice * Previous evidence or previous diagnosis of clinically relevant left heart disease and other relevant conditions, i.e. at least one of the following: * Previous ECHO with estimated left ventricular (LV) ejection fraction \< 50%, previous history of cardiogenic pulmonary edema, increased size of left atrium (\> 50 mm) * Known significant diastolic dysfunction associated with clinical heart failure or PCWP \> 15mmHg * Known significant coronary disease or significant valvular heart disease * Evidence of inadequately treated blood pressure, defined as \> 160/90 mmHg and/or blood pressure during exercise \> 220/120 mmHg (if evaluated) * Known hypertrophic cardiomyopathy or left ventricular hypertrophy (interventricular septum thickness (IVS) or posterior wall thickness (PWD) \> 1.2 cm) * Patients referred with overt heart failure * Known congenital heart defects such as single ventricle, transposition, or Eisenmenger physiology * Previous closure of systemic pulmonary shunt, heart valve replacement, or cardiac transplantation * Pregnancy: pregnancy testing in females with child-bearing potential is mandatory and must be done before enrolment * Patients unlikely to be available for annual follow up over an anticipated 3 years of study (e.g. survival estimate, psychological, logistics; based on investigator discretion) Patients with clinically relevant left heart disease as defined above, diagnosed by ECHO at baseline (i.e. after enrolment), will be included in the study.
