Chronic lung diseases are common causes of pulmonary hypertension. It ranks second after the left heart disease. Both obstructive and restrictive lung diseases are know to cause pulmonary hypertension. The pathophysiology of the disease is complex, and includes factors affecting the blood vessels, airways, and lung parenchyma. Hypoxia and the inhalation of toxic materials are another contributing factors. Recent guidelines have further clarified the association between pulmonary hypertension and chronic lung disease and made general guidelines concerning the diagnosis and management. In this article, we will provide a detailed revision about the new classification and give general recommendations about the management of pulmonary hypertension in chronic lung diseases.
