Pulmonary

Back to Library |
Pulmonary hypertension results in structural
damage to pulmonary vessels.
Increased pulmonary arterial pressure is pulmonary hypertension,
This causes irreversible structural changes in pulmonary arteries,
and leads to increased demand for work on the right side of the
heart and right heart failure (cor pulmonale).
the most important being:
• Chronic obstructive airways disease.
• Fibrosis of the lungs.
• Chronic pulmonary venous congestion.
In long-standing pulmonary hypertension, structural changes develop
in the lung including medial hypertrophy in muscular arteries
(with increase in amount of smooth muscle) and pulmonary veins
(arterialization).
There is occlusion of the lumen of pulmonary
arteries by intimal proliferation, and alveolar macrophages containing
haemosiderin are prominent. Fibrosis in the interstitium of the lung
develops in long-standing cases.
The clinical effects of pulmonary hypertension are breathlessness and
development of right-sided cardiac failure. |
