There is no clear and uniform time for the survival of patients with pulmonary hypertension, which should be judged in combination with the cause of the patient’s disease and condition, i.e., the rate of progression of the disease at the time of onset. Among them, some patients may not affect the life expectancy, but patients with critical conditions may even have life-threatening conditions at any time.1. Pathogenesis: When patients with pulmonary hypertension due to congenital dysplasia can improve the lesion through later surgical treatment, or even achieve a curative effect, it will not affect the patient’s life. For pulmonary hypertension caused by chronic diseases, such as chronic obstructive pulmonary disease in the elderly, or idiopathic pulmonary hypertension, after effective drug treatment, the condition is controlled smoothly, and clinical survival time of 10-20 years is more common. If the control is not ideal, leading to the aggravation of heart failure, it may affect the survival time; 2. Condition: When the patient has mild symptoms of pulmonary hypertension, the disease can be effectively controlled by medication and usually does not affect the patient’s daily life. For patients with higher pulmonary artery pressure, up to 70 mmHg, and more urgent onset, such as pulmonary embolism patients, the disease progresses faster at this time, and if resuscitation is not timely and thrombolytic therapy and anticoagulation therapy are not carried out, life threatening conditions may occur at any time due to respiratory and cardiac failure. In addition, the attack of pulmonary hypertension is more serious, often manifested as dyspnea, dizziness, weakness, angina, etc. However, with the progress of medical technology and drug treatment, the survival time of patients is also being extended accordingly. Therefore, when pulmonary hypertension occurs, patients should seek medical attention promptly, improve electrocardiogram, cardiac ultrasound and other examinations to clarify the condition, and take appropriate methods to control the condition as soon as possible under the guidance of doctors. The main control is through medication, and oxygen therapy is needed to prevent infection to prevent serious symptoms that could endanger life.
