With cor pulmonale, cor is Latin for heart and pulmonale is Latin for lungs.
Cor pulmonale, then, is a relationship between the two, it’s when a disorder of the lungs causes dysfunction of the heart.
The pulmonary circulation is a low-resistance system with pressures ranging between 10 mmHg and 14 mmHg.
This can happen in two ways, either it’s systolic heart failure, where the ventricles can’t pump blood hard enough during systole, or diastolic heart failure, where not enough blood fills the ventricles during diastole, called diastolic heart failure.
Heart failure can affect the right ventricle, the left ventricle, or both ventricles, so someone might have, right-sided heart failure, left-sided heart failure, or both which is called biventricular heart failure.
