肺高压(英语:pulmonary hypertension,PH,PHTN)或称肺动脉高压,是指因多种心、肺或肺血管疾病引起肺动脉压力升高,超过正常值的病理性状态,属于呼吸系统疾病中的肺循环疾病。[1]一般地,在标准海平面和静息下肺动脉收缩压超过30mmHg或舒张压超过15mmHg,或是肺动脉均压(mPAP)超过20mmHg,即认定肺动脉高压。[2]肺动脉高压呈进行性发展,会引起肺循环阻力增加,导致右心负荷增大,最终导致右心衰竭,继而引发一系列临床表现。[1]
肺动脉高压患者临床症状无特异性,可呈现呼吸困难、干咳、 晕厥、胸闷、胸痛和疲劳等症状,且活动后表现明显。对于重症患者,多有右心功能不全问题,临床可有颈静脉充盈、肝淤血、下肢、腹部或全身水肿等症状。[3]根据最新的分类,肺高压共有六种形式。[4]
症状及征象
较罕见的症状包含干咳、运动时晕眩和呕吐[6]。部分患者有咳血的现象,特别是肺高压的某些亚型,如遗传性肺动脉高压、艾森门格症侯群,和慢性栓塞型肺动脉高压等[8]。肺静脉高压的典型症状为卧姿时呼吸困难(端坐呼吸及阵发性夜间呼吸困难),肺动脉高压则无此现象[9]。
其他典型症状包含较强的第二心音。另外右心室肥大也会造成右心室产生第三心音,以及胸骨旁起伏。右心衰竭导致的全身性郁血则可能合并有颈静脉屈张、腹水,以及肝颈动脉回流[6][7][10] 。
另有证据显示肺动脉高压也可能导致三尖瓣闭锁不全以及肺动脉瓣逆流[6][7][11]。
病因
肺高压的病因常不明,也可由呼吸系统、循环系统疾病导致的肺动脉压力增高。1973年,世界卫生组织首次尝试将肺高压分类,当时分为原发性肺高压,以及次发性肺高压两大类,并将初级肺高压分为“丛状动脉型”(arterial plexiform)、“静脉阻塞型”(veno-occlusive),以及“血栓栓塞型”(thromboembolic)等[12]。1988年埃维昂莱班会议将次级肺高压按原因分类[13]。随着新研究的进展,2008年在达纳角召开的第四届世界肺动脉高压研讨会更新了定义。以下为达纳点的分类系统[4]:
治疗
肺高压可利用药物控制病情发展的程度,若针对第一型肺动脉高目前主要分有三种不同的标靶治疗途径: 1.内皮素1 2前列环素(PGI:途径) 3一氧化氮途径 而目前针对此三种不同途径的药物如下列所述: 1.内皮素1途径--Bosentan、Macitentan(双重ETA-ETB拮抗剂)、Ambrisentan(选择性ETA受体拮抗剂) 2.前列环素(PG₂I)途径--Epoprostenol、lloprost、Treprostinil(三者皆为PGl₂类似剂)、Selexipag(PGl受体奋剂) 3.一氧化氮途径--一氧化氮气体(刺激可溶性鸟苷酸环化酶)、Sildenafil(PDE5抑利剂)、口服Riociguat(直接sGC刺激剂)[14] 由于肺高压不能根治,若已引发较严重的心脏衰竭,就需要进行心肺移植,由于器官移植轮候需时,所以一旦确诊,除药物控制病情外,医生都会安排病人排入器官移植的等候名单,以期病人在症状恶化至严重心脏衰竭前,有适合器官进行移植手术[15]。
