Question

describe the relationship between cor pulmonale, pulmonary hypertension, and right ventricle hypertrophy (RVH).

Answer 1

Pulmonary hypertension is the increased blood pressure on arteries in the lungs and heart.

cor pulmonale: the dysfunction of the right ventricle due to pulmonary hypertension.

right ventricular hypertrophy: it is the enlargement of the right ventricular muscle due to pulmonary hypertension.

due to any lung disease(COPD), vasoconstriction occurs because of hypoxia or hypocapnia.it leads to increased alveolar pressure and pulmonary hypertension. this is followed by increased right ventricular afterload. Later , leads to right ventricular hypertrophy and cor pulmonale.
