What is cor pulmonale?

Cor pulmonale specifically refers to the condition where the right side of the heart is affected due to diseases of the lungs or pulmonary blood vessels. This can occur when there is increased pressure in the pulmonary arteries, often as a result of chronic respiratory illnesses such as chronic obstructive pulmonary disease (COPD) or pulmonary hypertension. These conditions lead to a strain on the right ventricle, ultimately resulting in its failure.

In essence, cor pulmonale highlights the close relationship between the lungs and the heart, where pulmonary pathology directly influences right heart function. This distinction is crucial because it emphasizes the importance of addressing underlying lung conditions to manage the heart's response effectively. Understanding this relationship is vital for healthcare professionals in both diagnosis and treatment strategies for affected patients.
