Despite the innovations introduced in the 2022 European Society of Cardiology/European Respiratory Society Guidelines on Pulmonary Hypertension, risk discrimination and management of pulmonary arterial hypertension (PAH) patients at intermediate risk still represents a grey zone. Additionally, clinical evidence derived from currently available studies is limited. This expert panel survey intends to aid physicians in choosing the best therapeutic strategy for patients at intermediate risk despite ongoing oral therapy. An expert panel of 24 physicians, specialized in cardiology and/or pulmonology with expertise in handling all drugs available for the treatment of PAH participated in the survey. All potential therapeutic options for patients at intermediate risk were explored and analyzed to produce graded consensus statements regarding: the switch from endothelin receptor antagonist (ERA) or phosphodiesterase 5 inhibitor (PDE5i) to another oral drug of the same class; the addition of a drug targeting the prostacyclin pathway administered by different routes; the switch from PDE5i to riociguat.
