The heart and lung are intricately linked. When the heart is
affected by disease, the lungs will often show some related
pathological or clinical conditions and vice versa. Pulmonary heart
disease is by definition a condition when the lungs cause the heart
to fail. The left ventricle in combination with the other
structures in the "left heart" pumps blood throughout the body. The
right ventricle (and structures of the "right heart") pumps blood
to the lungs where it is oxygenated and returned to the left heart
for distribution. In normal circumstances, the right heart pumps
blood into the lungs without any resistance. The lungs usually have
minimal pressure and the right heart easily pumps blood through.
However when there is lung disease present, like emphysema, chronic
obstructive lung disease (COPD) or pulmonary hypertension- the
small blood vessels become very stiff and rigid. The right
ventricle is no longer able to push blood into the lungs and
eventually fails. This is known as pulmonary heart disease.
Pulmonary heart disease is also known as right heart failure or cor
pulmonale. The chief cause of right heart failure is the increase
in blood pressure in the lungs (pulmonary artery).
