Drug treatment of pulmonary arterial hypertension: a narrative review by decision point

Description

Pulmonary arterial hypertension is a disease of the small arteries in the lungs. They narrow and stiffen, the pressure the right ventricle pumps against climbs, and the ventricle eventually fails. It is treated with drugs that were transformative when they arrived and are now numerous enough that the difficulty has moved: not whether to treat, but what to give, in what order, and to whom. Guidelines answer that in the language of trials and risk scores. What somebody standing in a catheter laboratory needs is the same information organised by the decision actually in front of them. That is how this project is written, by decision point rather than by drug class: the haemodynamics that establish the diagnosis, the risk status that sets the pace, the vasoreactivity test that sends a small minority to calcium channel blockers, then the drug classes by the pathway they act on and the question that follows each one, which is what to add and when. The reading starts from a list already built.

Student responsibilities

Read up on pulmonary arterial hypertension and the drug classes used to treat it. Take one decision point, read the papers gathered for it, build its table, and write that section of the review.
