I27.2: Other secondary pulmonary hypertension

Other secondary pulmonary hypertension is a specific type of high blood pressure that affects the arteries in the lungs and the right side of your heart. It begins when tiny arteries in your lungs, called pulmonary arteries, and capillaries become narrowed, blocked, or destroyed, making it harder for blood to flow through the lungs to pick up oxygen. Consequently, the pressure in your pulmonary arteries rises as your heart muscle has to work harder to pump blood through. Secondary pulmonary hypertension is a more specific term that means your condition is caused by another disease or condition, potentially including such things as heart or lung disease, liver disease, or blood clots in the lungs. Common symptoms may include shortness of breath during routine activity, fatigue, chest pain, a fast heartbeat, and a noticeable bluish color to the lips and skin (cyanosis). Progression of the disease can lead to more severe symptoms and complications, including right heart failure.
