Seen with pulmonary hypertension are small peripheral pulmonary arteries that are quite thickened . the larger pulmonary arteries demonstrate atherosclerosis with pulmonary hypertension 图示肺动脉高压见明显增厚的肺外周小动脉。较大的肺动脉显示伴有肺动脉高压的动脉粥样硬化。
However , if there are lots of small emboli , particularly if they are showered to the lungs over a period of time , then they collectively may block enough small arteries to produce pulmonary hypertension 然而,如果存在大量小血栓，尤其是同时进入肺组织，就会共同堵塞很多小动脉，引起肺高血压。
Pulmonary embolism pain may be pleuritic when infarction of the lung results in pleuritis or may be anginal when right ventricular ischemia occurs secondary to sudden onset of pulmonary hypertension 肺栓塞性疼痛可因肺梗死引起胸膜炎而呈胸膜性，也可因继发于突发性肺动脉高压的右心室缺血而呈绞痛样。
Lung transplants are a common therapy for many end - stage lung diseases such as chronic obstructive pulmonary disease , cystic fibrosis , pulmonary hypertension , idiopathic pulmonary fibrosis and other diseases 肺移植是许多终末期肺病的普遍治疗方法，例如慢性阻塞性肺病、囊性纤维病、肺动脉高血压、特发性肺纤维化等疾病。
Pulmonary hypertension , classified as group iii in the world health organization classification scheme for pulmonary hypertension , may result in severe right ventricular dysfunction caused by lung disease , also known as cor pulmonale 由肺疾病引起的肺动脉高压在世界卫生组织肺高压分类表里被划为第iii类，它可导致严重的右心功能受损，也就是常说的肺源性心脏病。
The research on effect of sildenafil on human physiological functions at high altitude and its use in prevention and treatment of high altitude pulmonary hypertension , high altitude pulmonary edema and high altitude hypoxemia , and improving motor ability are reviewed 本文综述了西地那非对高原人体生理的作用及其用于防治高原肺动脉高压、高原肺水肿、高原低氧血症,提高运动能力方面的研究进展。
Proliferation of vascular smooth muscle cells is involved not only in the process of pulmonary hypertension but also in many other vascular diseases such as atherosclerosis and restenosis after angioplasty or coronary artery bypass grafting ( cabg ) Vsmcs的异常增殖除了参与肺动脉高压的形成，还与动脉粥样硬化、血管成形术后再狭窄过程中血管内膜的增厚关系密切， vnp对肺动脉之外的其它血管平滑肌的异常增殖是否有调节作用尚无报道。
Vasonatrin peptide ( vnp ) is a man - made new member of natriuretic peptide family . previous studies have demonstrated that vnp was effective in preventing and treating hypoxic pulmonary hypertension and right ventricular hypertrophy , and inhibiting the proliferation of pulmonary artery smooth muscle cells 血管钠肽( vasonatrinpeptide , vnp )是人工合成的钠尿肽家族新成员，研究表明vnp能防治低氧条件下大鼠肺动脉高压和右心室肥厚的形成，并能抑制肺动脉平滑肌细胞的增殖。
