Usually not. Primary pulmonary hypertension usually strikes at random, without any clear familial tendency. Nobody understands why. Other pulmonary hypertension is secondary to some other lung disease. Best wishes.
It may be inherited. Up to 5% of patients with pulmonary arterial hypertension (pah) may have a genetic or heritable cause. Research studies have identified a genetic abnormality affecting bone morphogenetic protein receptor 2 (bmpr2) that appears to predispose a patient to pah. Fortunately, even if an individual inherits the abnormal gene, the likelihood of developing pah is only 1 in 5.
Yes and No. Not all forms of pulmonary hypertension are heritable. Pulmonary hypertension can develop due to severe chronic lung or heart disease, chronic thrombotic disorders, sickle cell disease & rare blood vessel disorders. Certain rare types of pulmonary hypertension associated with bmpr-2 mutations are heritable. Please consult a lung specialist for full diagnostic work up.
