Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by vasculopathy and progressive fibrosis of the skin and visceral organs (gastrointestinal tract, heart, kidneys and lungs). Although the prevalence is low, SSc is a disease with high morbidity and mortality. Since pulmonary arterial hypertension (PAH) associated with SSc (SSc-PAH) and clinically evident cardiac involvement is associated with increased mortality, the cardiac complications and PAH in SSc are reviewed. ⋯ Recently the DETECT algorithm, a 2-step screening algorithm is proposed in a SSc-subgroup at increased risk for PAH, but further validation is needed. Despite current treatment options with prostacyclins, endothelin-1 receptor antagonists and phosphodiesterase type-5 inhibitors, mortality remains high. Several promising new treatment options for PAH are evaluated in phase II and III clinical trials.
