The majority of cases of pulmonary arterial hypertension (PAH) are not preventable. Patients should avoid using anorexigen drugs as well as illicit stimulant drugs such as amphetamine-derivatives and cocaine. To minimize potential contributions from WHO group 3 disease, patients should not smoke. Those with obstructive sleep apnea or other lung disease should be optimally treated for these diseases to avoid further insults from hypoxemia/chronic pulmonary disease.
