Abstract:
Pulmonary hypertension (PH) is frequent in the course of chronic respiratory diseases with hypoxia which leads to vascular remodeling, especially chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis. PH is usually moderate but may be disproportionate in some patients. In the chronic diseases of the left heart, increased atrial pressure results in pulmonary venous distension and passive PH (post-capillary) which may further lead to precapillary hypertension. A precise diagnosis of PH in chronic respiratory and cardiac diseases requires right heart catheterization. The possible role of specific treatments of PH in these disorders is not established.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
