What causes Group 2 pulmonary hypertension?
Group 2 pulmonary hypertension is caused by left-sided heart disease. This means conditions affecting the left side of the heart are the root cause.
Common conditions that lead to Group 2 PH include:
* Heart valve disease
* Heart muscle weakness
* Chronic inability of the heart to pump blood efficiently
When the heart can't pump effectively, blood backs up into the pulmonary circulation. Over time, this damages the blood vessels in the lungs and raises pressure.
Group 2 is actually the most common type of pulmonary hypertension. The initial treatment usually focuses on managing the underlying heart condition that's causing the elevated lung pressure.
