Pulmonary hypertension is when the average pressure in the pulmonary arteries is greater than 3.33 kpa (25 mm hg) when the body is quiet and inactive, or greater than 4 kpa (30 mm hg) when the body is in motion. Pulmonary vascular resistance is the ratio of the difference between the mean pulmonary venous pressure and the mean pulmonary venous pressure to the pulmonary blood flow. Therefore, any factor that increases pulmonary venous pressure, pulmonary blood flow and pulmonary vascular resistance will cause pulmonary hypertension. So what are the manifestations of pulmonary hypertension?


(1) labor dyspnea: it is easy to understand, that is, after the completion of some physical activities, patients will have dyspnea, mainly due to the decline in the compliance of pulmonary blood vessels, resulting in the amount of blood output of the heart can not increase with the need for exercise, so that the body appears oxygen-deficient performance. Typically, difficulty breathing during physical activity, such as playing basketball or football, is one of the earliest signs of PULMONARY hypertension.

(2) fatigue: and labor dyspnea, also because the amount of blood output of the heart is not enough to meet the amount of blood required by the body, there is not enough blood to carry oxygen, it will lead to the body’s various tissues in a state of hypoxia, and then appear symptoms of fatigue.


(3) Syncope: It is mainly caused by a sudden decrease in blood supply to the brain tissue, which often occurs after exercise or when suddenly standing up. It can also be caused by a large embolus blocking the pulmonary artery, a sudden spasm of the pulmonary arterioles, or an abnormal beating of the heart.


(4) Angina pectoris or chest pain: Mainly because the right ventricle becomes hypertrophy, and the coronary arteries that supply blood to the heart are reduced, resulting in a relative lack of blood supply to the heart muscle, resulting in angina pectoris or chest pain symptoms.


(5) hemoptysis: hemoptysis refers to the coughing of blood from the respiratory tract is taken out, pulmonary hypertension will make some of the capillaries in the lungs at the beginning of the microhemangioma rupture, resulting in the coughing of blood from the lungs.


(6) hoarseness: This is due to the excessive expansion of the pulmonary artery, the compression of the human recurrent laryngeal nerve, resulting in hoarseness.
