Correct answer: D — Idiopathic, heritable and drug-associated pulmonary arterial hypertension

Acute vasoreactivity testing for selection of high-dose calcium-channel-blocker treatment is confined to idiopathic, heritable or drug-associated pulmonary arterial hypertension. It is not recommended for other PAH associations or for groups 2, 3 or 4 because a positive acute response does not identify a group with established durable benefit and treatment may cause harm.
