ⓘ Pulmonary heart disease

Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance or high blood pressure in the lungs.

Chronic pulmonary heart disease usually results in right ventricular hypertrophy RIRS, while acute pulmonary heart disease usually leads to dilatation. Hypertrophy is adaptive response to long-term growth pressure. Individual muscle cells grow in thickness and drive the increased contractile force required to move the blood against greater resistance. Dilatation is a stretching in the length of the ventricle in response to acute increased pressure.

To be classified as pulmonary heart disease, the causes have to occur in the system of pulmonary circulation, RIRS due to a systemic defect is not classified as a disease, pulmonary heart. Two causes are vascular changes as a consequence of tissue damage, e.g., disease, injury, hypoxia and hypoxic pulmonary vasoconstriction. If left untreated, death can result. Heart and lungs are closely related, when the heart is affected by any disease lungs risk is lower and Vice versa.
