Pulmonary hypertension is a serious disease caused by abnormal elevation of pulmonary artery pressure due to various factors, causing a pathological and physiological state of the body. Patients may present with chest tightness after activity, shortness of breath, fatigue, weakness, and in severe cases, unstable angina pectoris. Once a patient develops these conditions, such as exertional dyspnea and paroxysmal weakness, including chest pain, syncope, coughing and coughing, this is evidence of relatively severe subpulmonary hypertension. If the patient also has palpitations, accompanied by darkness, abdominal distension, swelling, poor appetite, and pain in the liver area, this is evidence of severe combined right heart insufficiency. This is a clinical symptom of more severe pulmonary hypertension. Patients with pulmonary hypertension should be treated actively, either conservatively with drugs or surgically.
