Description

Condition characterised by dyspnea, slowly developing asthma, bronchitis, and chronic cyanosis in association with polycythemia. Polycythemia usually results from chronic pulmonary insufficiency and sclerosis of the pulmonary vascular bed. Cardiac involvement may be present, usually in the form of dilatation and hypertrophy of the right heart. Pulmonary arterial hyperplasia and stenosis, emphysema, and fibrosis may be the contributing factors. Splenomegaly, clubbing of the fingers, congestion of the liver, and heart failure are associated.

In 1901 Abel Ayerza lectured on the syndrome of chronic cyanosis, dyspnoea, erythraemia, and sclerosis of the pulmonary artery. He did not publish this work, but an important discussion on the nomenclature was given by Luis Ayerza in 1925. The term Ayerza's disease was introduced by F. C. Arrilaga. Baron Jean-Nicolas Corvisart des Marest (1755-1821) mentioned the condition in 1806.
