I27: Other pulmonary heart diseases
I27.0: Primary pulmonary hypertension
You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result.
The pressure in the blood vessels in your lungs is too high. The exact reason for this is not known. The blood vessels in the lungs have changed due to this disorder. The blood vessels are getting narrower.
The blood is not able to flow through the lungs properly. The blood is getting held up. As a result, the blood pressure in the lungs is building up. If the pressure in the lungs is too high, the heart has to work harder to pump the blood. The heart can get damaged as a result.
