Pulmonary arterial hypertension (PAH) is a rare, progressive disorder characterised by high blood pressure in the arteries of the lungs, due to thickening and stiffening of the walls of the smaller branches of the pulmonary arteries. Over time, PAH damages the heart, which has to work harder to overcome this arterial resistance.
PAH can be associated with a number of conditions, including connective tissue diseases (such as scleroderma), portal hypertension, HIV, and certain medications/drugs. The cause may be unknown (idiopathic PAH).

Parkinson's disease (PD) is a chronic, progressive neurodegenerative condition caused by lack of dopamine in the brain, due to loss of the dopamine-containing cells of the substantia nigra.
PD is a movement disorder with four core features: tremor (shaking), bradykinesia (slowness of movement), rigidity (muscle stiffness) and postural instability (difficulty with balance and coordination).
Pulmonary embolism/emboli (PE) occurs when a blood vessel in the lung(s) is blocked by a blood clot.
PERLA means pupils equal and reactive to light and accommodation.
PEARL means pupils equal and reactive to light; PERRLA means pupils equal, round and reactive to light and accommodation.
Patent foramen ovale (PFO) occurs if the foramen ovale, a hole between the heart's atria made in normal foetal development, does not close after birth as it should.
PFO is common, affecting about 1 in 4 people.
PFO can increase risk of ischaemic stroke, because thrombi (blood clots) can pass from the right to the left side of the circulation and more easily reach the brain - normally small thrombi are filtered out by the lungs.
