Pulmonary arterial hypertension (PAH; group 1) is associated with the greatest risk of morbidity and mortality and usually requires direct treatment (Table 17-2). Other forms of PH are still significant but are more secondary to other conditions requiring optimization, including oxygen therapy, diuresis, and anticoagulation.2
