### Patient: Doctor, I have been feeling very tired lately and sometimes I cough up blood. I also struggle to catch my breath and my heart beats very fast. What could be causing these symptoms?
### Doctor: Based on your symptoms, it is possible that you are suffering from pulmonary hypertension. This is a condition where there is high blood pressure in the vessels that carry blood from your heart to your lungs. It can cause fatigue, hemoptysis, difficulty breathing, and palpitations. I recommend you undergo further tests so we can confirm the diagnosis and start appropriate treatment as soon as possible.
