I27.20: Pulmonary hypertension in chronic thromboembolic disease
The blood vessels in your lungs are consistently being blocked by blood clots. As a result, the pressure in the blood vessels in your lungs is too high.
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. Blood clots keep forming in your body. The blood clots can get into the lungs via the blood. The blood clots have blocked blood vessels in your lungs.
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.
