Pulmonary Hypertension

Pulmonary hypertension is increase in blood pressure of pulmonary artery, pulmonary vein, or pulmonary capillaries. It can be broadly classified into 5 groups: (1) pulmonary arterial hypertension, often idiopathic; (2) pulmonary hypertension associated with left heart disease, i.e. mitral stenosis; (3) pulmonary hypertension associated with lung diseases and/or hypoxemia; (4) pulmonary hypertension due to chronic thromboembolic disease; and (5) miscellaneous. The chief symptom is shortness of breath, and the feared long-term consequence is right heart failure (cor pulmonale).
