肺动脉高压（Pulmonary hypertension） In China, it is estimated that each patient needs 20, 000 yuan per month. Download (11.24 KB) 2010-11-6 09:55 The cause of The degree of pulmonary hypertension depends on the associated heart deformities, and the common causes of congenital heart disease that cause secondary pulmonary hypertension include: Download (3.85 KB) 2010-11-6 09:55 Aortic stenosis, main pulmonary artery window, atrial septal defect, complete atrial septal defect, artery Narrowed, dilated cardiomyopathy, right ventricular double outlet, hypertrophic cardiomyopathy, mitral stenosis, arterial catheter, single ventricle, persistent arterial, ventricular septal defect Symptoms of pulmonary hypertension include shortness of breath, ease of fatigue, fainting, chest pain and edema of the legs and ankles. In addition, heart auscultation can detect a high level of P2. If not treated, the patients pulmonary hypertension will gradually increase and even shorten life expectancy. Most of the symptoms associated with pulmonary hypertension stem from the failure of the right heart system. Because the right heart is to pump blood into the lungs, if the pressure of the pulmonary artery increases gradually, it will be the right ventricular load is increasing, and then the above symptoms appear. classification Whether the pathogenesis is clear, it is divided into idiopathic and secondary pulmonary hypertension. According to pulmonary artery resistance, cardiac output and pulmonary artery wedge pressure, the increase of PAWP was divided into three categories. The result of the increase of pulmonary arterial resistance is called capillary presex pulmonary hypertension, such as primary pulmonary hypertension, pulmonary embolism, etc. Hyperkinetic pulmonary hypertension caused by increased cardiac output, such as congenital heart disease and hyperthyroidism; The increase of PAWP is called capillary posterior pulmonary hypertension, such as mitral stenosis, left heart failure, etc., al
