肺高壓(pulmonary hypertension,PH,PHTN)或肺動脈高壓,是肺動脈壓力持續性超過正常值的病理狀態。一般定義靜息下,肺動脈收縮壓超過30mmHg或舒張壓超過15mmHg,或是肺動脈均壓(mPAP)超過20mmHg,即為肺動脈高壓[1]。肺動脈高壓可引起肺內血流動力學改變和右心功能障礙。
肺高壓會造成疲勞、勞力性呼吸困難、胸部不適、頭暈、昏厥、下肢水腫,肺高壓患者會因為心臟負荷增加令運動能力急速下降,以及發生其他症狀,可引致心臟衰竭導致病患死亡[2]。此症於1891年由恩斯特·馮·倫伯格首次描述[3]。根據最新的分類,肺高壓共有六種形式[4]。
症狀及徵象
較罕見的症狀包含乾咳、運動時暈眩和嘔吐[6]。部分患者有咳血的現象,特別是肺高壓的某些亞型,如遺傳性肺動脈高壓、艾森門格症侯群,和慢性栓塞型肺動脈高壓等[8]。肺靜脈高壓的典型症狀為臥姿時呼吸困難(端坐呼吸及陣發性夜間呼吸困難),肺動脈高壓則無此現象[9]。
其他典型症狀包含較強的第二心音。另外右心室肥大也會造成右心室產生第三心音,以及胸骨旁起伏。右心衰竭導致的全身性鬱血則可能合併有頸靜脈屈張、腹水,以及肝頸動脈回流[6][7][10] 。
另有證據顯示肺動脈高壓也可能導致三尖瓣閉鎖不全以及肺動脈瓣逆流[6][7][11]。
病因
肺高壓的病因常不明,也可由呼吸系統、循環系統疾病導致的肺動脈壓力增高。1973年,世界衛生組織首次嘗試將肺高壓分類,當時分為原發性肺高壓,以及次發性肺高壓兩大類,並將初級肺高壓分為「叢狀動脈型」(arterial plexiform)、「靜脈阻塞型」(veno-occlusive),以及「血栓栓塞型」(thromboembolic)等[12]。1988年埃維昂萊班會議將次級肺高壓按原因分類[13]。隨著新研究的進展,2008年在達納角召開的第四屆世界肺動脈高壓研討會更新了定義。以下為達納點的分類系統[4]:
治療
肺高壓可利用藥物控制病情發展的程度,若針對第一型肺動脈高目前主要分有三種不同的標靶治療途徑: 1.內皮素1 2前列環素(PGI:途徑) 3一氧化氮途徑 而目前針對此三種不同途徑的藥物如下列所述: 1.內皮素1途徑--Bosentan、Macitentan(雙重ETA-ETB拮抗劑)、Ambrisentan(選擇性ETA受體拮抗劑) 2.前列環素(PG₂I)途徑--Epoprostenol、lloprost、Treprostinil(三者皆為PGl₂類似劑)、Selexipag(PGl受體奮劑) 3.一氧化氮途徑--一氧化氮氣體(刺激可溶性鳥苷酸環化酶)、Sildenafil(PDE5抑利劑)、口服Riociguat(直接sGC刺激劑)[14] 由於肺高壓不能根治,若已引發較嚴重的心臟衰竭,就需要進行心肺移植,由於器官移植輪候需時,所以一旦確診,除藥物控制病情外,醫生都會安排病人排入器官移植的等候名單,以期病人在症狀惡化至嚴重心臟衰竭前,有適合器官進行移植手術[15]。
