If the heart disease pulmonary hypertension is in the compensated stage and there are no complications, it is usually possible to have children. If it is in the decompensated stage and is complicated by pulmonary encephalopathy, arrhythmia, etc., it is not recommended to have children. Heart disease pulmonary hypertension, also known as pulmonary heart disease, is mainly due to lesions in the lung tissue, pulmonary blood vessels and other pathologies, resulting in increased resistance of the pulmonary blood vessels, which leads to pulmonary hypertension, followed by changes in the structure and function of the right ventricle. 1. If the pulmonary heart disease is in the compensatory stage, only palpitation, cough, sputum, fatigue and other discomforts after activities, and no other uncomfortable symptoms, it is usually able to tolerate normal labor or cesarean section, so it is able to give birth to a child. However, the decision should be made after a comprehensive assessment by a doctor. 2. If the patient is in the decompensated stage, respiratory failure and right heart failure may occur, manifested by dyspnea, obvious shortness of breath, abdominal distension, nausea and other discomforts; at the same time, respiratory failure may also lead to hypoxia, resulting in carbon dioxide retention secondary to pulmonary encephalopathy, as well as cardiac arrhythmia, shock and other complications, then it is not recommended to give birth to a child. Whether heart disease pulmonary hypertension can have children, it is recommended to go to the hospital in a timely manner, after the doctor combined with a comprehensive assessment of the condition of the decision.
