Patient's question:
My best friend has hypertension, and they take medication to lower their blood pressure every day. People say that more activity is good for blood pressure, but my best friend gets dizzy even with slight movement. Later, it was found that the dizziness was caused by pulmonary artery hypertension. What is pulmonary artery hypertension? What is pulmonary artery hypertension?Doctor's answer:
Pulmonary hypertension is divided into two categories: primary (or idiopathic) and secondary. Primary pulmonary hypertension is an endothelial tumor of the pulmonary artery, equivalent to the rapid growth and filling of the pulmonary artery lumen after malignant transformation of endothelial cells. As a result, all venous blood is blocked on one side by the pulmonary artery. Without proper treatment, patients quickly die from intractable right heart failure. 75% of patients with pulmonary hypertension die within 5 years of diagnosis, with a mean survival time of 1.9 years after recurrent episodes; those with symptoms of right heart failure have a shorter average survival time of less than 1 year.
